The present invention generally concerns audio accessories and specifically relates to a head- phone and connecting cable combination.

BACKGROUND

Different types of music equipment/audio devices frequently use different types of inter- connectable male and female connectors of different sizes that are commonly jointly referred to as headphone connectors. Examples thereof are mobile phones and various types of portable AV devices, such as mp3 players, that in most cases are equipped with a 3,5 mm size female connector that is commonly named a minijack or mini socket and that is intended for receiving a corresponding 3,5 mm size male connector that is commonly named a miniplug or minijack plug. On the contrary, professional audio equipment frequently uses a bigger 6.3 mm size female connector, namely a jack socket also commonly named a ¼ inch jack, a full-size jack or a phono jack that is intended for receiving a corresponding 6,3 mm size male connector/plug. It is often regarded as a problem that such different connector types/sizes are used in various types of audio devices and equipment. It has the effect that users frequently switching between e.g. portable devices and non-portable equipment are required to employ an adapter when connecting accessories, such as headphones thereto. Such adapters are often small in size and are therefore easily misplaced or even lost.

DETAILED DESCRIPTION

The invention will be explained with reference to exemplifying embodiments of an audio accessory of the invention, including alternative uses thereof and alternative components included therein. These embodiments of the invention are described below and are illustrated in the accompanying drawing figures. They relate to an application of the inventive solution to an exemplary headphone and connection cable combination. It is emphasized that the illu- strations are for the sole purpose of describing exemplary embodiments of the invention and are not intended to limit the invention to details or to any specific field of application thereof. The inventive solution may thus be used with and for other than the illustrated and described types of headphones and connection cables as well as audio devices and equipment that are all appropriate for such applications. Expressions such as user equipment, audio devices and audio equipment shall therefore throughout this specification include any type of equipment in connection with which audio accessories including a headphone and a connection cable may be employed. It shall be realized that the invention covers the incorporation of such application related features and any combination of features disclosed herein. It is stated throughout this specification that the headphones have a separate connection cable and it shall be emphasized from the beginning that this shall mean that the connection cable is not stationary or fixed to the headphone but is readily connectable and disconnectable in relation thereto. Parts of the specification also refer in general to interconnectable male and female connectors of different types and or standards. For the purposes of the invention this may theoretically include interconnectable connectors of any type that may be used for connecting audio devices or audio equipment to an accessory, such as headphones. At the present time such male and female connectors are mainly connector plugs (often referred to also as jack plugs, phono plugs etc.) and connector jacks (often referred to also as sockets or jack sockets) of the TRS or TS type. Of such connectors a 3,5 mm size plug (often referred to as a standard minijack connector) and jack is the standard for music headphones and most other electronic devices/user equipment, such as mobile phones, whereas a 6,3 mm plug and jack is the standard for professional equipment, such as mixer tables or boards etc.

As was discussed in the introduction a common problem in association with connecting audio accessories to different types of audio devices as well as to audio equipment is the different types and/or standards of male and female connectors used therein. The invention attempts to overcome the disadvantages and problems encountered with the present commonly used solution of using separate small adapters that are often lost. The invention proposes a new approach for making this type of adapters superfluous in such applications. Specifically, the basic idea of the proposed solution is to provide an accessory including headphones and a separate connection cable having interconnectable connectors of two different types. This will provide the desired optional connection variants since the same cable may be used for connecting the headphones to most devices and equipment by simply turning the cable around.

The invention will be explained below with reference to exemplifying schematical embodiments thereof that are illustrated in the accompanying drawing figures 1-5. In Figs. 1A-B is disclosed an exemplary embodiment of the inventive audio accessory to which the basic concept of the invention has been applied. In particular, Figs. 1A-B schematically illustrate headphones 2 and a connection cable 3 being included in an audio accessory 1 (Figs. 2 and 3) of the invention. The headphones 2 are of a basic type having two ear-cups 7, 8 supported by a headband 6. The connection cable 3 is a separate component used for connecting head- phones 2 to user equipment 10, e.g. portable audio devices such as music players or mobile phones schematically indicated in Fig. 2, or alternatively to other audio equipment 11, such as a non-portable sound mixer board as schematically indicated in Fig. 3. The connection cable illustrated in Fig. IB has connection plugs 4B, 5B of mutually different types being provided at each of its two ends. In this embodiment one 4B of the connection plugs is a 3,5 mm (1/8 inch) size standard TRS or TS type male connector provided at one cable 3 end. The other connection plug 5B is a 6,3 mm (1/4 inch) size standard TRS or TS type male connector provided at the opposite end of the cable 3. The headphones 2 illustrated in Fig. 1A have separate sockets 4A, 5 A of said different types being provided in one 7 of the ear-cups for connection to a respective mating connection plug 4B and 5B, respectively, at an end of the connection cable 3. In this case one 4A of the sockets is thus a 3,5 mm (1/8 inch) size standard TRS or TS type female connector and the separate, slightly spaced other 5 A socket is a 6,3 mm (1/4 inch) size standard TRS or TS type female connector. In the illustrated embodiment the connection cable 3 is also equipped with a microphone 9 for allowing two-way communication, but it should be obvious that the inclusion of such a microphone is optional and does not form any actual part of the invention. With reference to Figs. 2 and 3, the described embodiment of the audio accessory 1 of the invention may be used in two basic applications APP I and APP II. In the application APP I illustrated in Fig. 2 the connection cable 3 of Fig. IB is connected with its 6,3 mm size connection plug 5B at one end of the connection cable 3 to a 6,3 mm size socket 5 A of the headphones 2. The 3,5 mm size connection plug 4B at the other, opposite end of the connection cable 3 is connected to a mating 3,5 mm size socket 4A commonly found in predominantly portable user equipment 10, such as an mp3 music player or a mobile telephone for one- or two-way audio communication there between.

In an alternative application APP II of the inventive audio accessory 1 illustrated in Fig. 2, the cable 3 of Fig. IB is simply turned around and connected with its 3 ,5 mm size connection plug 4B at one end of the connection cable 3 to the headphones 2. The 6,3 mm size connection plug 5B at the other end of the connection cable 3 is then connected to a mating 6,3 mm size socket 5 A commonly found in predominantly stationary or nonportable audio devices 11 , such as professional audio equipment. The switch between e.g. the described examples of applications may thus be performed without any small sized, easily misplaced or even lost adapters.

In Fig. 4 is illustrated an alternative second embodiment of a pair of headphones 102 for inclusion in an audio accessory 1 of the invention, likewise in combination with a connection cable 3 as shown in Fig. IB. Like before, the headphones 102 have two ear-cups 7, 8 supported by a headband 6 and two separate sockets 4A, 5 A of said different types for connection to one each of the connection plugs 4B, 5B at the respective ends of the connection cable 3. However, in this embodiment is shown a variation of the first embodiment of Fig. 1A. Specifically, the separate sockets 4A, 5A are here provided in a separate ear-cup 7, 8, and specifically the left ear-cup of Fig. 4 is equipped with the 3,5 mm size socket 4 A and the right ear-cup of Fig. 4 is equipped with the 6,3 mm size socket 5 A.

In Fig. 5 is illustrated a further alternative third embodiment of a pair of headphones 202 for inclusion in an inventive audio accessory 1 , likewise in combination with a connection cable 3 as shown in Fig. IB. The headphones 202 likewise have two ear-cups 7, 8 supported by a headband 6 and separate sockets 4A, 5 A of said different types for connection to one each of the connection plugs 4B, 5B at the respective ends of the connection cable 3. However, in this embodiment is shown a further variation of the first embodiment of Fig. 1A. Specifically, in this case the separate socket types 4A, 5 A are paired in both ear-cups 7, 8, and specifically the left 7 as well as the right 8 ear-cup of Fig. 5 is equipped with both a 3,5 mm size socket 4A and a 6,3 mm size socket 5A.

Finally, in Fig 6 is illustrated an alternative embodiment of an audio accessory 301 of the invention. This variation is provided in order to exemplify the possible inclusion of other types of connectors in the headphones 302 and connection cable 303 of the audio accessory 301. In the given embodiment are used headphones 302 and connection cable 303 that are basically the same as those of the previously described ones, except for the use of an alternative type of connector. Specifically, the left ear-cup 7 of the headphone 302 of Fig. 6 has a female connector/socket 4A of the earlier described 3,5 mm size standard TRS or TS type, and one end of the connection cable 303 has a mating male connector/plug 4B of the 3,5 mm size standard TRS or TS type. However, here the ear-cup 7 also has a second female connector 305A that is an USB type socket. The opposite end of the connection cable 303 has a mating male connector 305B being an USB type plug for connection to the USB socket 305A of the headphones 302 or alternatively to mating USB sockets that are becoming increasingly common in user equipment. It will be clear that also this variation of the inventive audio accessory may be used in the previously described alternative modes or applications involving a simple turning around of the cable. As stated above, the general object of the invention is to provide a solution that will make the presently commonly used separate small adapters superfluous in applications involving switching between different types of devices and equipment. This object is achieved by providing an accessory having the integrated adapter function to allow such switching without using separate additional adapters. For example, by providing the two different types of connectors in both the headphones and in the separate connection cable the switching between different types of devices may be performed by simply turning around the cable.

In alternative, but not specifically illustrated embodiments of the invention variations of the different illustrated parts of the inventive accessory may be employed without departing from the scope of the invention. An example of this is a use of the inventive solution to a headset type of accessory having only one ear-cup with two separate sockets being provided therein. Likewise, the connection cable of the accessory may or may not have the illustrated microphone. It shall also be emphasized that although the invention has been described and illustrated with specific reference to indicated applications thereof, the invention is in no way restricted to such applications. The basic principles of the invention may be used in association with other types of headphones and connection cables as well as audio devices/equipment and specifically also with other present and future types of connectors.

The invention has been described in connection with what is presently considered the most practical and preferred embodiments, but it is to be understood that the invention is not limited to the disclosed embodiments. The invention is therefore intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
