Abstract
A microphone includes a case including a plurality of sound holes; a first sound device installed at positions corresponding to at least two sound holes in the case; a second sound device spaced apart from the first sound device in the case and installed at a position corresponding to at least one sound hole; and a semiconductor chip electrically connected to the first sound device and the second sound device, where the at least two sound holes formed in the positions corresponding to the first sound device are each formed in upper and lower surfaces of the case on the basis of the first sound device.
Claims17
A microphone comprising:
- a case in which a plurality of sound holes are formed;
- a first sound device mounted in the case and installed at a position corresponding to at least two sound holes formed in an upper surface and a lower surface of the case, respectively;
- a second sound device mounted in the case, installed to be spaced apart from the first sound device by a predetermined interval, and installed at a position corresponding to another sound hole formed in the case;
- and
- a semiconductor chip electrically connected to the first sound device and the second sound device.
A microphone comprising:
- a first sound device receiving a sound source signal and outputting a first sound output signal;
- a second sound device formed to be spaced apart from the first sound device by a predetermined interval, receiving the sound source signal and outputting a second sound output signal;
- a case in which the first sound device and the second sound device are positioned, a first sound hole and a second sound hole are formed in an upper side and a lower side of the first sound device, respectively, and a third sound hole is formed in a position corresponding to the second sound device;
- and
- a semiconductor chip positioned on the second sound device and outputting a final sound signal based on the first sound output signal and the second sound output signal.
A microphone comprising:
- a case in which a first sound hole and a second sound hole are formed in an upper side and lower side, respectively, and a third sound hole is formed;
- a first sound device positioned between the first sound hole and the second sound hole in the case;
- a second sound device formed at a position corresponding to the third sound hole in the case;
- and
- a semiconductor chip positioned on the second sound device,
- wherein each of the first sound device and the second sound device includes a substrate, a vibration membrane formed over the substrate, and a fixed membrane formed over the vibration membrane to be spaced apart from the vibration membrane by a predetermined interval, and
- the first sound device and the second sound device are electrically connected to each other through a first connection part and a second connection part formed in the respective substrates.
