Vibrating diaphragm with concave-convex reinforcing ribs

Abstract

The invention discloses a vibrating diaphragm with concave-convex reinforcing ribs. The vibrating diaphragm is used for a telephone receiver. At least one end of the vibrating diaphragm is connected with a vibrating diaphragm support, the vibrating diaphragm support is fixedly connected with a shell of the telephone receiver, one end of the vibrating diaphragm is in transmission connection with a conducting rod of the telephone receiver, the vibrating diaphragm comprises a vibrating diaphragm body and convex hulls, and the convex hulls include the first convex hulls which are convex upwards and the second convex hull which is convex downwards. The vibrating diaphragm with the concave-convex reinforcing ribs is simple in structure, the vibrating strength is higher on the premise that the thickness is not changed, the vibrating amplitude is higher, smoothness and stability of vibration of the vibrating diaphragm can be effectively guaranteed, the sound quality of the telephone receiver can be effectively guaranteed, and the vibrating diaphragm with the concave-convex reinforcing ribs is more suitable for large telephone receivers.

Description

technical field [0001] The invention relates to a vibrating membrane of a receiver, in particular to a vibrating membrane with concave-convex reinforcing ribs. 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. Among them, the diaphragm 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. , the lar...

Problems solved by technology

However, when the thickness of the diaphragm is ensured, the vibration strength of the diaphragm is difficult to be guaranteed

If the diaphragm is too thin, the vibration of the diaphragm will be unstable when it vibrates, and it is likely to form a wave-shaped vibration, which will cause noise interference to the receiver
