A microphone system has a lid coupled with a base to form a package with an interior chamber. The package has a top, a bottom, and a plurality of sides, and at least one of those sides has a portion with a substantially planar surface forming an opening for receiving an acoustic signal. The microphone system also has a microphone die positioned within the interior chamber. The microphone is positioned at a non-orthogonal, non-zero angle with regard to the opening in the at least one side.

A microphone is provided that ensures the electrical connection between a unit case and an audio-signal output circuit board. The microphone includes a unit case 10 having a shape of a hollow cylinder with a closed end and accommodating an electroacoustic transducer 20, an audio-signal output circuit board 40 connected to the electroacoustic transducer, and a microphone case accommodating the unit case and the audio-signal output circuit board, wherein the audio-signal output circuit board has a receiver 41 disposed on a portion of the peripheral edge of the audio-signal output circuit board, and an open end 11 of the unit case comes into contact with the receiver and is positioned when the unit case and the audio-signal output circuit board are accommodated in the microphone case.

A connector for a microphone and a microphone are provided that can prevent loose connections to a microphone stand. The connector for the microphone is to be inserted into a connector support hole of a microphone stand. The connector includes pins to be electrically connected to the microphone stand, a connector body accommodating the pins, a sleeve disposed on the outer circumferential surface of the connector body, and an elastic member for biasing the sleeve toward the rear end of the connector body. The sleeve has an insertion portion to be inserted into a space between the connector body and the connector support hole.

There is provided an electrodynamic sound transducer comprising a chassis and at least one diaphragm which is capable of vibrating and which at its edge has at least two oppositely disposed fixing portions for fixing the diaphragm to the chassis. The edge of the diaphragm is not connected to the chassis between the fixing portions so that the diaphragm can vibrate freely at those locations.

A MEMS microphone and a manufacturing method thereof. The method comprises: sequentially forming a first isolation layer, a diaphragm, and a second isolation layer on a substrate; sequentially forming a first protective layer, a backplate electrode, and a second protective layer on the second isolation layer; forming a release hole penetrating through the first protective layer, the backplate electrode, and the second protective layer; forming an acoustic cavity penetrating through the substrate; releasing the diaphragm through the acoustic cavity and the release hole; and forming a groove on a surface of the first isolation layer, wherein the diaphragm conformally covers the surface of the first isolation layer, thereby forming a spring structure at a position of the groove.

Provided is an organic light emitting display device. The organic light emitting display device includes a display area including a plurality of pixels and a non-display area enclosing the display area, the organic light emitting display device comprises an organic light emitting display panel including a plastic base member, a back plate which is disposed below the organic light emitting display panel and includes a polymer material, a support substrate which is disposed below the back plate and includes a hole formed so as to correspond to a part of the display area, and a microphone module below the support substrate. The microphone module includes a diaphragm which is disposed to overlap at least a part of the hole, a core which is disposed below the diaphragm and is formed of a magnet, and a coil which encloses around the core.

The present invention provides a vibration motor including a housing with an accommodation space, a vibration member and a fixed member accommodated in the accommodation space, and an elastic support member suspending the vibration member. The elastic support member has an elastic arm, a first fixed part, and a second fixed part. Both the first fixed part and the second fixed part are bent toward the same side of the elastic arm, and the vibration member is located between the first fixed part and the second fixed part. The elastic stress of the elastic support member is effectively improved and the service life of the elastic support member is improved.
