Receiver with multi-plate diaphragm

Abstract

The invention discloses a receiver with a multi-piece type vibration film. The receiver with the multi-piece type vibration film comprises a shell body, a sound production unit and a drive device. The drive device comprises a vibration film unit. The vibration film unit comprises a vibration film support which is fixedly connected with the inner wall of the shell body, at least one connecting part and a vibration film which is fixedly connected with the other end of the connecting part, and one end of the connecting part is fixedly connected with the vibration film support. The receiver with the multi-piece type vibration film is not only capable of guaranteeing soundness of connecting and reducing process difficulties, but also capable of not scarifying low frequency.

Description

technical field

[0001] The invention relates to a receiver, in particular to a receiver with a multi-piece diaphragm. Background technique

[0002] The receiver, also known as the earpiece, is an electroacoustic device that converts audio electrical signals into sound signals without sound leakage. It is widely used in communication terminal equipment such as mobile phones, fixed phones, and earphones to realize audio, such as voice and music. Waiting for replay. In the receiver, the conversion of the electrical signal to the sound signal is mainly completed by an internal drive device, which mainly includes an armature, a coil, a magnet, and a diaphragm unit. Among them, the diaphragm unit is a more important part, its function is to compress the air in the front cavity through vibration, drive the air to vibrate and output the sound from the sound unit, and the amplitude range of the diaphragm also determines the sound frequency. High and low, the greater the vibrating r...
