    摘要: A microphone front chamber structure is adapted to be disposed on a front side of a voice reception hole of a microphone unit. The microphone front chamber structure includes a shell and a microphone holder. The shell has a first hole. The microphone holder is disposed in the shell and has a second hole corresponding to the first hole. The first hole and the second hole form a front chamber. The first hole has a first width at a position farthest away from the microphone holder. The second hole includes first and second sections arranged along an axis. On the axis, the first section has a tapered width along the axis and away from the shell. The second section has a second width constant along the axis. The first width is greater than the second width. A voice reception device including the microphone front chamber structure is also provided.

    摘要: The present invention provides a MEMS microphone, including: a base with a back cavity; and an electric capacitance system arranged on the base. The electric capacitance system includes a back plate, a first diaphragm and a second diaphragm opposite to the back plate and arranged on an upper and lower sides of the back plate. The MEMS microphone further includes an insulation layer isolating the base, the back plate, the first diaphragm and the second diaphragm, and a sealing space formed between the first diaphragm and the second diaphragm. The pressure in the sealing space is equal to an external pressure.

    摘要: The present disclosure provides a vibration sensor including a vibration assembly including a mass element and an elastic element, a first acoustic chamber, an acoustic transducer, and a buffer member. In response to an external vibration signal, the vibration assembly vibrates such that a volume of the first acoustic chamber changes. The acoustic transducer is in communication with the first acoustic chamber. In response to a volume change of the first acoustic chamber, the acoustic transducer may generate an electrical signal. The buffer member is connected to the mass element or the elastic element. The buffer member reduces an impact force of the mass element acting on the elastic element during a vibration process of the vibration assembly. The acoustic transducer has a first resonance frequency, the vibration assembly has a second resonance frequency, and the second resonance frequency is less than the first resonance frequency.
