Document Type and Number:
WIPO Patent Application WO/2018/126832
Kind Code:
A1
Abstract:
Disclosed are a condenser microphone with mutually switched bi-directional and non-directional functions, and an electronic device, which relate to the technical field of microphone structures. In the condenser microphone and the electronic device, when a sealing component is not located at the position of an upper opening or a lower opening, and is not attached to the upper opening or the lower opening, the condenser microphone has a bi-directional function; whereas when the sealing component is located at the position of the upper opening or the lower opening, and is attached to the upper opening or the lower opening, the condenser microphone has a non-directional function. Therefore, the condenser microphone provided by the embodiments of the present invention has a dual function of bi-directionality and non-directionality, and can be switched between the bi-directional function and the non-directional function, such that a bi-directional condenser microphone can be switched to a non-directional condenser microphone, thereby broadening the usage range thereof.
