Document Type and Number:
WIPO Patent Application WO/2020/107400
Kind Code:
A1
Abstract:
The present application relates to the technical field of loudspeakers, and provides a receiver and a hearing aid with the receiver. The receiver comprises an upper shell, a lower shell, an armature, a first permanent magnet, a second permanent magnet, a coil and a sealing membrane, wherein the upper shell and the lower shell are snap-fitted to each other, and the armature is fixedly mounted between the upper shell and the lower shell; the first permanent magnet is fixed to an inner surface of the upper shell, the second permanent magnet is fixed to an inner surface of the lower shell, a magnetic field is formed between the first permanent magnet and the second permanent magnet, and one end of the armature is located between the first permanent magnet and the second permanent magnet; the coil is wound around the armature; and the sealing membrane is fixed to one end of each of the upper shell and the lower shell. Based on the structure, the receiver, compared to a traditional receiver, omits an iron core and a vibrating membrane. Due to the fact that the iron core is omitted, the first permanent magnet and the second permanent magnet are respectively directly fixed to the upper shell and the lower shell, thereby effectively reducing the thickness of the receiver and reducing the volume of the receiver.
