Document Type and Number:
WIPO Patent Application WO/2021/047274
Kind Code:
A1
Abstract:
The present invention provides a diaphragm and a receiver using the diaphragm. The diaphragm comprises: a fixing frame, having an inner cavity running through the fixing frame in the thickness direction; a reed, having a hinge end connected to the fixing frame and a vibration end suspended in the fixing frame; and a vibration plate, fixedly connected to the vibration end of the reed, the vibration plate being suspended in the fixing frame, and a predetermined gap being formed between the vibration plate and the fixing frame. Compared with the prior art, the diaphragm in the present invention can improve high frequency response while ensuring high air vibration efficiency, thereby improving the overall condition and performance of a receiver.
