[0001] This application claims priority to German Patent Application No. 10 2016 217 082.1, filed on September 8, 2016, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND OF THE INVENTION

Field of the Invention

[0002] The present invention relates to a communication device for use with at least one personal protection system, a mask for use with a communication device, and a holding device for use with a communication device.

Description of Related Art

[0003] Emergency personnel such as firefighters are required to participate in missions involving different situations that require products for self -protection. In particular, helmets in combination with fire protection jackets and trousers are often required. During use, the helmet is often combined with a respiratory mask which forms part of an air supplying device.

[0004] In addition the emergency personnel require good communication devices. During operations the communication between the team leader and the team members is important. Typically analogue or digital wireless communication are used. Specific communication devices are known for applications with a helmet or a helmet-mask combination that are either integrated into the helmet or into the mask.

[0005] DE 10 2013 011 195 Al describes a personnel protection system that includes a helmet with a first microphone device arranged on the helmet and a second microphone device that is arranged at a breathing or respiratory mask. A remote communication device is communicatively connected to the first microphone device. Further connecting devices such as Bluetooth connect the second microphone device with the remote communication device. This communication device is only suitable for a personal protection system consisting of a helmet and a mask.

[0006] There is however a need for clear communication in challenging and noisy environments while wearing different personal protection systems that do not include a full mask such as a singular helmet, helmet suspension, head gear, protective glasses or a half mask device. SUMMARY OF THE INVENTION

[0007] Generally, provided is an improved communication device that can be easily interchanged between different personal protection systems while providing at the same time clear communication that is easily understood.

[0008] According to a preferred and non-limiting embodiment, example, or aspect, provided is a communication device for use with at least one personal protection system, in a preferred and non-limiting embodiment, example, or aspect, a head gear device. The communication device includes: at least one microphone module and at least one loudspeaker module, wherein the microphone module and the loudspeaker module are flexibly connected to each other by at least one connector that allows for an adjustment of the distance between the microphone module and the loudspeaker module. The at least one microphone module can include a housing with at least two sections each one having at least one microphone. A first microphone can be arranged in at least one of the housing sections and a second microphone can be arranged in the other housing section. The two microphones can be arranged a predetermined distance to each other within the housings. The first housing section with the first microphone can include an insertion mechanism for inserting the first housing section into the loudspeaker module in a first functional mode or for inserting the first housing section into a receiving element mounted to a protective head gear device, in a preferred and non-limiting embodiment, example, or aspect, a mask, in a second functional mode.

[0009] In a preferred and non-limiting embodiment, example, or aspect, the communication device can be used with any head gear device, such as, in a preferred and non-limiting embodiment, example, or aspect, a helmet and its suspension components, protective glasses, a half-mask device, and/or a full-mask device.

[0010] In a preferred and non-limiting embodiment, example, or aspect, the communication device can allow for flexible mounting to different head set devices and can provide a large field of applications and options. In a preferred and non-limiting embodiment, example, or aspect, also provided can be the specific combination and flexibility in mounting the communication device and also transferring the communication device to other users. At the same time the communication device can provide clear communication while the user is wearing different personal protection systems in noisy environments. [0011] In a preferred and non-limiting embodiment, example, or aspect, the communication device can allow for clear speaking and understanding through transmitting a signal to a remote speaker microphone that can be connected to a transmitting device (in a preferred and non-limiting embodiment, example, or aspect, a radio, or an LTE mobile). In a preferred and non-limiting embodiment, example, or aspect, the communication device can also enable communications in explosive environments. In a preferred and non-limiting embodiment, example, or aspect, the communication device can also be specifically designed for individual personal protection systems such as masks or helmets while fulfilling the need for close team communication without feedback sounds. In a preferred and non-limiting embodiment, example, or aspect, the communication device can be compatible with different helmets and masks and can also be worn on a head band holder, either on the left or on the right side of the head, and can be mounted and detached easily and quickly.

[0012] While known head set solutions offer a good intelligibility, they are mostly mounted and restricted to just one special personal protection system or are inserted into the ear, which may be impractical for users such as, in a preferred and non-limiting embodiment, example, or aspect, firefighters. The ability to switch ears is valuable to users that have a preference between their right ear or left ear.

[0013] In a preferred and non-limiting embodiment, example, or aspect, the communication device can offer several advantages including an easy donning and doffing which can allow handing over of the communication device to other teammates, and easy maintenance of the attached personal protection systems. In a preferred and non-limiting embodiment, example, or aspect, the communication device including two microphones has improved speech intelligibility. In a preferred and non-limiting embodiment, example, or aspect, versatile attachment options to different personal protection systems can allow for a secure voice communication device in many different work environments.

[0014] In a preferred and non-limiting embodiment, example, or aspect, the at least two housing sections of the microphone module can be designed in a hollow shape, respectively. In a preferred and non-limiting embodiment, example, or aspect, the at least two microphones can be placed or disposed within the hollow shaped housing sections.

[0015] In a preferred and non-limiting embodiment, example, or aspect, the two housing sections of the microphone module can be designed as hollow cylinders. [0016] In a preferred and non-limiting embodiment, example, or aspect, the housing sections can have a cylindrical, hexagonal, square-shaped form, or any other suitable shape.

[0017] In a preferred and non-limiting embodiment, example, or aspect, both housing sections can be connected to each other in order to form one microphone module or housing. In a preferred and non-limiting embodiment, example, or aspect, one microphone can be disposed in one housing section, and a second microphone can be disposed in the other housing section. In a preferred and non-limiting embodiment, example, or aspect, the housing sections can be connected to each other and form one piece. In a preferred and non-limiting embodiment, example, or aspect, the housing sections with the respective microphone in each section may be arranged in-line (i.e., the two microphones are arranged to each other at an angle of 180°) or on an angle (i.e., the two housing sections are arranged in an angle smaller than 180° such as 100-120° to each other). However, this is not to be construed in a limiting sense since the spatial arrangement of the two housing sections with the respective microphones can be selected to optimize speech and sound quality.

[0018] In a preferred and non-limiting embodiment, example, or aspect, the housing of the microphone module may be made of plastic or any other suitable material.

[0019] In a preferred and non-limiting embodiment, example, or aspect, the communication device can include an automatic switch for switching between the at least two microphones of the microphone module depending on which functional mode is being used. In a preferred and non- limiting embodiment, example, or aspect, such automatic switch can allow for the use of only one of the microphones depending on the functional mode of the device for a specific personal protection system thereby providing a clear communication signal. In a preferred and non-limiting embodiment, example, or aspect, the automatic switch between the two microphones within the housing of the microphone module can, in a preferred and non-limiting embodiment, example, or aspect, be provided by way of a reed contact or any other similar type of contact switch including, in a preferred and non-limiting embodiment, example, or aspect, a hall effect switch using a magnet. Thus, in a preferred and non-limiting embodiment, example, or aspect, when switching between the functional modes, one or the other of the two microphones can be activated.

[0020] In a preferred and non-limiting embodiment, example, or aspect, the two functional modes of the communication device can include a first mode wherein the communication device is mounted to a helmet (without any mask) or to a helmet suspension, and a second functional mode wherein the communication device is mounted to a gas mask or other respiratory mask. [0021] In a preferred and non-limiting embodiment, example, or aspect, in the first functional mode (i.e., the communication device is mounted or attached to a helmet or helmet suspension or an arm band) the first housing section with the first microphone can be inserted into the loudspeaker module. In a preferred and non-limiting embodiment, example, or aspect the first housing section can include at least two slots or slits on opposite sides as an insertion mechanism in order to allow easy sliding of the first housing section into a corresponding receiving element in the loudspeaker module. In a preferred and non-limiting embodiment, example, or aspect, the receiving element can be a pocket provided with projections corresponding to the slots or slits on the first housing section.

[0022] In a preferred and non-limiting embodiment, example, or aspect, in the first functional mode, the second housing section with the second microphone may not be inserted into the loudspeaker module and can thus be outside of the loudspeaker module. In a preferred and non- limiting embodiment, example, or aspect, the second microphone (i.e., the microphone that is not inserted into the loudspeaker module) can be used for communication in the first functional mode. Thus, in a preferred and non-limiting embodiment, example, or aspect, the second microphone can pick up the voice of the person wearing the helmet or helmet suspension with the attached communication device directly near the mouth and can subtract noise from the voice signal on a physical based method.

[0023] In a preferred and non-limiting embodiment, example, or aspect, in the second functional mode (i.e., communication device mounted or attached to a mask), the first housing section with the first microphone can be inserted into a suitable receiving element (may also be described as an adapter) on the mask for receiving the first housing section with the first microphone of the microphone module. In a preferred and non-limiting embodiment, example, or aspect, the first microphone can automatically be activated (in a preferred and non-limiting embodiment, example, or aspect, by a contact as a switch) when inserted into the mask receiving element or adapter. Thus, in a preferred and non-limiting embodiment, example, or aspect, the first microphone of the first housing section can be inserted into the receiving element on the mask and can be used for communication in the second functional mode.

[0024] In a preferred and non-limiting embodiment, example, or aspect, in the second functional mode, the voice can be captured in front of a speech diaphragm and guided into a permanently inserted funnel. In a preferred and non-limiting embodiment, example, or aspect, the funnel can be a part of the mask adapter that can be permanently attached to the mask.

[0025] In a preferred and non-limiting embodiment, example, or aspect, each of the at least two microphones of the microphone module can be an electret microphone, a condenser microphone, or a piezoelectric microphone. In a preferred and non-limiting embodiment, example, or aspect, each microphone is desirably an electret microphone. An electret microphone is a type of electrostatic capacitor-based microphone that eliminates the need for a polarizing power supply by using a permanently charged material. Specifically, an electret is a stable dielectric material with a permanently embedded static electric charge (which, due to the high resistance and chemical stability of the material, will not decay for hundreds of years). An advantage of using electret microphones is that the microphones are able to filter ambient noise.

[0026] In a preferred and non-limiting embodiment, example, or aspect, one or more electret microphones are desirably used for the free standing arrangement of the microphone module. In a preferred and non-limiting embodiment, example, or aspect, an electret microphone is used for the second microphone used in the first functional mode on a helmet or head support system (i.e., for the second microphone in the second housing section of the communication device that is not inserted into the loudspeaker module and is arranged in front of the mouth of the person wearing the communication device attached to the helmet or head band).

[0027] In a preferred and non-limiting embodiment, example, or aspect, the at least one connector between the microphone module and the loudspeaker module can include a wired connection, such as a spiral cable, or a wireless connection, such as, in a preferred and non-limiting embodiment, example, or aspect, Bluetooth. In a preferred and non-limiting embodiment, example, or aspect, the connector can allow for high flexibility regarding direction and length between the microphone module (comprising the housing with the at least two microphones) and the loudspeaker module, especially, in a preferred and non-limiting embodiment, example, or aspect, in the case of the second functional mode (i.e., the communication device used with a helmet and mask).

[0028] In a preferred and non-limiting embodiment, example, or aspect, the loudspeaker module can include at least one element for receiving the at least one first housing section of the microphone module with the first microphone. In a preferred and non-limiting embodiment, example, or aspect, and as previously described, the first housing section can include at least two slots or slits on opposite sides in order to allow an easy sliding of the housing section into a corresponding receiving element such as a pocket (provided on the back side of the loudspeaker module) with projections corresponding to the slots or slits on the first housing section. In a preferred and non-limiting embodiment, example, or aspect, the receiving element of the loudspeaker module can allow for the easy insertion of the first housing section into the loudspeaker module, in a preferred and non-limiting embodiment, example, or aspect, by sliding.

[0029] In a preferred and non-limiting embodiment, example, or aspect, the first housing section of the microphone module may be held in place in the loudspeaker module by way of a clip, such as, in a preferred and non-limiting embodiment, example, or aspect, a release clip or a spring clip. In a preferred and non-limiting embodiment, example, or aspect, the clip can be arranged on the backside of the loudspeaker module. In a preferred and non-limiting embodiment, example, or aspect, the microphone module can be removed from the first receiving element by overcoming the spring clip.

[0030] In a preferred and non-limiting embodiment, example, or aspect, the loudspeaker module can include at least one further mechanism for detachable connection of the loudspeaker module to at least one holding device that can be attached to a head gear device, such as, in a preferred and non-limiting embodiment, example, or aspect, a helmet, a head support system, helmet suspension, protective glasses, a half-mask and/or a full-mask device. In a preferred and non-limiting embodiment, example, or aspect, the at least one further mechanism for detachable connection may be configured as a receiving mechanism for an element of a holding device (in a preferred and non-limiting embodiment, example, or aspect, in the form of a pocket). In a preferred and non-limiting embodiment, example, or aspect, there may be at least two pockets formed on the back side of the loudspeaker module as the receiving mechanism. In a preferred and non- limiting embodiment, example, or aspect, the pockets can be placed on the end of the backside of the loudspeaker module opposite to the (first) receiving element on the loudspeaker module for mating with the microphone module. In a preferred and non-limiting embodiment, example, or aspect, the two pockets can be placed (in a mirror image) along the longitudinal sides of the loudspeaker module. This can allow a switching of the wearing positions of the loudspeaker module and thus the communication device. In a preferred and non-limiting embodiment, example, or aspect, the communication device may be worn either on the left or on the right side of a person's head. The pockets can also allow for easy mounting and demounting of the communication device to a head gear device.

[0031] In a preferred and non-limiting embodiment, example, or aspect, the loudspeaker module can include an unlocking element for unlocking the loudspeaker module from the holding device. In a preferred and non-limiting embodiment, example, or aspect, by pressing the unlocking element the complete loudspeaker module (including the microphone module if attached) can be removed from the holding device (such as, in a preferred and non-limiting embodiment, example, or aspect, a swivel) attached to a head gear device (such as, in a preferred and non-limiting embodiment, example, or aspect, a helmet).

[0034] In a preferred and non-limiting embodiment, example, or aspect, the sound transmitting device can be designed and located such that the sound is tunneled from the speech membrane directly to the location of the first microphone that is arranged in the receiving element (or adapter) provided on the outer surface of the mask. In a preferred and non-limiting embodiment, example, or aspect, the sound transmitting device can be connected to the mask receiving element of the head gear.

[0035] In a preferred and non-limiting embodiment, example, or aspect, the at least one sound transmitting device can be provided as a sound channel, a sound funnel, a wire coupling and/or a wireless coupling. In a preferred and non-limiting embodiment, example, or aspect, the at least one sound transmitting device can be a sound funnel made of any suitable synthetic material, such as silicon, rubber or any plastic material.

[0036] According to a preferred and non-limiting embodiment, example, or aspect, a holding device for detachably mounting a communication device to at least one head gear device is provided that includes at least two parts: at least one swivel mechanism for receiving the at least one loudspeaker module of the device and at least one adapter allowing for the mounting of the swivel mechanism with, in a preferred and non-limiting embodiment, example, or aspect, the loudspeaker module, to the at least one head gear device.

[0037] In a preferred and non-limiting embodiment, example, or aspect, the swivel mechanism (in a preferred and non-limiting embodiment, example, or aspect) shaped as a latch can be inserted into at least one further (second) receiving element (in a preferred and non-limiting embodiment, example, or aspect, in the form of a pocket or a slit or slot) provided at the loudspeaker module for detachably connecting the loudspeaker module to the holding device.

[0038] In a preferred and non-limiting embodiment, example, or aspect, the holding device can allow for flexible use of the communication device. In a preferred and non-limiting embodiment, example, or aspect, the holding device can allow for easy interchange of the communication device between different head gear devices. In a preferred and non-limiting embodiment, example, or aspect, the swivel mechanism can be in the form of a swivel arm or a pivoting arm for receiving the loudspeaker module of the communication device to provide a way of connecting the communication device to any type of personal protection system in a universal manner.

[0039] In a preferred and non-limiting embodiment, example, or aspect, the at least one mounting adapter can form a part of the holding device and can be attachable to a helmet, a head support system (head band), protective glasses, a half-mask and/or a full-mask device.

[0040] In a preferred and non-limiting embodiment, example, or aspect, the at least one mounting adapter may be constructed like a clamp for attachment to a band or strap of a helmet or mask. In a preferred and non-limiting embodiment, example, or aspect, the mounting adapter may also be constructed with a mounting mechanism such that it can be directly fixed or attached to a helmet. In a preferred and non-limiting embodiment, example, or aspect, the at least one mounting adapter can be positioned on either the left or the right side of the head gear device.

[0041] In a preferred and non-limiting embodiment, example, or aspect, the mounting adapter can include a receiving element for receiving a swivel mechanism.

In a preferred and non-limiting embodiment, example, or aspect, the cylinder head of the swivel arm can be rotatably stored within the hollow cylinder in order to allow for movement of the swivel arm and thus movement and adaptation of the arrangement of the loudspeaker module (as part of the communication device) to the person wearing the personal protection gear.

[0043] In a preferred and non-limiting embodiment, example, or aspect, the specific construction or design of the latch in conjunction with the receiving element of the mounting adapter can enable the microphone module to be positioned in a working position with a first movement and moved from that working position with a second movement which is in the opposite direction of the first movement.

[0044] In a preferred and non-limiting embodiment, example, or aspect, an opposite construction of the swivel mechanism and mounting adapter is also conceivable.

However, the description of connector 30 being a coiled cable is not to be construed in a limiting sense, since it is envisioned that connector 30 can be a wireless connection such as, in a preferred and non-limiting embodiment, example, or aspect, a Bluetooth connection.

[00132] With reference to Fig. 1A, in a preferred and non-limiting embodiment, example, or aspect, microphone module 10 can include a housing with two sections 11, 12. In each of the sections there is one microphone 13, 14 provided. Thus, the first microphone 13 is arranged in the first housing section 11 and the second microphone 14 is arranged in the second housing section 12. Due to the arrangement in a housing made of, in a preferred and non-limiting embodiment, example, or aspect, a rigid plastic material, the two microphones 13, 14 can be arranged a predetermined distance to each other within the housing. The distance of the microphones as well as the spatial arrangement (angle) between the microphones can be, however, adjustable, in a preferred and non-limiting embodiment, example, or aspect, to the respective user. In a preferred and non-limiting embodiment, example, or aspect, the second microphone 14 can be an electret microphone. [00133] In a preferred and non-limiting embodiment, example, or aspect, the first housing section 11 with the first microphone 13 can include an insertion mechanism 11a for attaching the first housing section 11 to the loudspeaker module 20 in a first functional mode or to an adapter 41 mounted to a face piece, in particular a mask 40 in a second functional mode (see Fig. 3A).
