    Abstract: Disclosed is a structure for detecting the vibration displacement of a speaker, including: a vibration system having a movable pole plate; a magnetic circuit system; and a fixed pole plate provided under the vibration system and opposite to the movable pole plate, the movable pole plate and the fixed pole plate constituting a capacitor. Also disclosed is an acoustoelectric inter-conversion dual-effect device, further including an impedance transformer connected to the capacitor and including a field effect transistor and a diode. In the present invention, a movable pole plate of a capacitor is provided on a vibration system and a fixed pole plate is provided under the vibration system and fixed in position. When the vibration system vibrates, the change in capacitance is detected to calculate the actual displacement of the vibration system, which can reduce the power of the speaker device when the actual displacement of the vibration system exceeds a safety threshold. For an electronic device adopting such a speaker structure, the displacement of the vibration system of a speaker product can be detected in real time at the system end of the electronic device.

    Abstract: Described is an air valve and a speaker containing the air valve described. The air valve comprises a valve body, an elastic valve plate, an air inlet penetrating through an inner surface and an outer surface of the valve body, and an air outlet penetrating through an inner surface and an outer surface of the valve plate. The valve plate is connected with the valve body in a sealing manner to form an annular sealing area encircling the air outlet and the air inlet. The inner surface of the valve body covers the air outlet, and/or the inner surface of the valve plate covers the air inlet. The air valve can be opened or closed via elastic deformation of the valve plate of the air valve. Therefore, the air valve can be perfectly matched with smaller sized products, reducing the difficulty in adjusting the micro speaker in a limited space.

    Abstract: The present invention discloses a quasi-differential capacitive MEMS pressure sensor and manufacturing methods thereof. The quasi-differential capacitive MEMS pressure sensor includes a first lower electrode, a second lower electrode, a first upper electrode supported above the first lower electrode, and a second upper electrode supported above the second lower electrode, wherein the first upper electrode is a pressure-sensitive film, and a cavity between the first upper electrode and the first lower electrode is a closed cavity, so that the first upper electrode and the first lower electrode constitute an air pressure-sensitive type capacitor; and the second upper electrode and the second lower electrode constitute a reference capacitor whose capacitance does not vary with external air pressure. The pressure sensor provided by the present invention can at least partially filter out a common-mode interference signal in an output signal of the air pressure-sensitive type capacitor by use of the reference capacitor, thereby improving the stability and resolution of the output signal of the air pressure-sensitive type capacitor.
