Abstract:
A microphone unit includes a housing having a first main surface and a second main surface disposed opposite each other. The housing surrounds an inner chamber which includes a resonance chamber. The first main surface includes a concave indentation facing toward the inner chamber. A hearing aid, including a substantially cylindrical battery and a microphone unit is also provided.
Abstract:
A microphone porting and venting assembly (100) is formed of a remote support substrate (118) providing a (130) acoustically resistive element with dedicated venting cavities (132) along with an external baffle (220) providing acoustic channels (212, 214, 216) which further provide water drainage and external sound sampling points (222, 224, 226). The microphone porting and venting assembly (100) is well suited waterproof, noise cancelling microphone systems.
Abstract:
A capacitive microphone and method of fabricating the same are provided. One or more holes can be formed in a first printed circuit board (PCB). A diaphragm can be surface micromachined onto an interior surface of the first PCB at a region having the one or more holes. Interface electronics can also be interconnected to the interior surface of the PCB. One or more spacer PCBs can be attached to a second PCB to the first PCB, such that appropriate interconnections between interconnect vias are made. The second PCB and first PCB with spacers in between can be attached so as to create a cavity in which the diaphragm and interface electronics are located.
Abstract:
A receiver, a mobile terminal device having the same includes a main circuit disposed upward by a predetermined gap from a bottom surface of a bracket housed within the mobile terminal device. The receiver includes a diaphragm provided at the other side of the bracket separated by a predetermined gap from the main circuit and a container shape in which a circuit is wired within the bracket and that houses a receiver mesh in an area in which a portion of a lower surface of the container shape is opened and that mounts a magnet on an injection structure molded at a periphery of the receiver mesh and the diaphragm covers an upper portion of the receiver mesh and the magnet and a coil fixed to the diaphragm and facing the magnet.

Abstract:
A personalized housing for a consumer product, such as as speaker, includes a customizable cover at least partially covering the product and a set of at least two end caps coupled to the product. The end caps are oriented in at least partial opposition to each other and installed using an interference fit. A vibration dampening connector or buffer couples the end caps to the product. The butler is arranged such that urging the end caps onto the product couples the end caps in a releasable interference fit, and the cover remains coupled to the product when the end caps are pulled from the cover. The cover allows access to controls located on the product, for example volume and input controls, may be made of at front panel covering only the front of the product, and a corresponding enclosure that covers the top, rear and sides of the product.
Abstract:
A portable audio input/output device may include one or more openings that extend through a cover of the device and allow acoustic signals outside a housing of the device to reach a microphone disposed within the housing. The opening(s) may be illuminated by a light guide disposed within the housing, which scatters light emitted from lights disposed within the housing. In some instances, a hole may pass through a printed circuit board to allow acoustic signals to be received by the microphone disposed below the printed circuit board. An input/output (I/O) interface module with multiple buttons and inputs may be installed in the hole. The multiple buttons and I/O ports of the I/O interface module may be aligned along an axis vertical relative to the housing and centered with respect to each other.
Abstract:
The present invention relates to a silicon based MEMS microphone, comprising a silicon substrate and an acoustic sensing part supported on the silicon substrate, wherein a mesh-structured back hole is formed in the substrate and aligned with the acoustic sensing part, the mesh-structured back hole includes a plurality of mesh beams which are interconnected with each other and supported on the side wall of the mesh-structure back hole, the plurality of mesh beams and the side wall define a plurality of mesh holes which all have a tapered profile and merge into one hole in the vicinity of the acoustic sensing part at the top side of the silicon substrate. The mesh-structured back hole can help to streamline the air pressure pulse caused, for example, in a drop test and thus reduce the impact on the acoustic sensing part of the microphone, and also serve as a protection filter to prevent alien substances such as particles entering the microphone.
Abstract:
A protective cover for an electronic device that has an interactive control panel and one or more electrical contacts includes a protective shell having first member and a second member. The second member is configured to join with the first case member to at least partially cover the electronic device. An aperture defined by the protective shell is aligned with the interactive control panel when the electronic device is at least partially enclosed by the protective shell. A securing mechanism secures the first member with the second member. An electrical connection attached to the protective shell is configured to connect an electrical source to at least one of the electrical contacts of the electronic device to provide an electrical connection to the electrical source when the electronic device is received by the first member.
Abstract:
An apparatus for measuring a plurality of loudspeakers arranged at different positions includes a generator of a test signal for a loudspeaker; a microphone device configured for receiving a plurality of different sound signals in response to one or more loudspeaker signals emitted by one of the loudspeakers in response to the test signal; a controller for controlling emissions of the loudspeaker signals by the loudspeakers and for handling the different sound signals so that a set of sound signals recorded by the microphone device is associated with each loudspeaker in response to the test signal; and an evaluator for evaluating the set of sound signals for each loudspeaker to determine at least one loudspeaker characteristic for each loudspeaker and for indicating a loudspeaker state using the at least one loudspeaker characteristic. This scheme allows automatic, efficient and accurate measurement of loudspeakers arranged in a three-dimensional configuration.
