    Abstract: The present invention provides a directional MEMS microphone and a receiver device wherein MEMS microphone comprises a microphone cover, a printed circuit board (PCB), a application specific integrated circuit (ASIC) chip, a MEMS die, a diaphragm, a damping, a metal wire(s), at least two internal acoustic ports and at least two external acoustic ports corresponding to the internal acoustic ports. The microphone further comprises a tuning cavity which includes a first tuning cavity by which a first internal acoustic port is communicated with a first external acoustic port, or by which a second internal acoustic port is communicated with a second external acoustic port. Compared with the prior art, the directional MEMS microphone including the tuning cavity to form a sound transmission channel by connecting the internal acoustic port and the external acoustic port expands the sound transmission distance, thereby increasing the sensitivity the directivity of the MEMS microphone.

    Abstract: A packaged MEMS device may include an embedding arrangement, a MEMS device disposed in the embedding arrangement, a sound port disposed in the embedding arrangement and acoustically coupled to the MEMS device, and a grille within the sound port. Some embodiments relate to a sound transducer component including an embedding material and a substrate-stripped MEMS die embedded into the embedding material. The MEMS die may comprise a diaphragm for sound transduction. The sound transducer component may further comprise a sound port within the embedding material in fluidic or acoustic contact with the diaphragm. Further embodiments relate to a method for packaging a MEMS device or to a method for manufacturing a sound transducer component.

    Abstract: A microphone rubber apparatus mounted on an SMD microphone prepared on a printed circuit board to protect the SMD microphone from an external physical impact and the like in a portable communication device such as a portable terminal and a Personal Digital Assistant (PDA). The microphone rubber apparatus includes a microphone holder portion formed to engage with and wrap up a microphone, a connection portion protruding to one side of the microphone holder portion and delivering a transmission sound to the microphone through an inside thereof, and at least one shock absorbing portion deformably formed around the connection portion to ease an impact caused by an external force. Thus, the shock absorbing portion having a wrinkled shape can be deformed no matter in which direction an impact is applied to the portable communication device, thereby easing the impact and preventing the microphone rubber from being detached from the microphone due to the external impact or during a distribution test.

    Abstract: An audio speaker has at least one transducer for converting electrical signals into mechanical motion. There is a planar sound producing structure that has a first face and a second face. A mechanical connection connects the at least one transducer to the sound producing structure, such that mechanical motion produced by the at least one transducer induces the sound producing structure to vibrate and produces sound from the first face and the second face. A deflector is interposed between the at least one transducer and the sound producing structure. The deflector is adjacent to the second face of the sound producing structure and reflects the produced sound from the second face of the sound producing structure to a listening area forward of the first face.
