Vibrating diaphragm with reinforcing rib structure and telephone receiver

Abstract

The invention discloses a vibrating diaphragm with a reinforcing rib structure and a telephone receiver. The vibrating diaphragm is used for the 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, reinforcing ribs are arranged on the vibrating diaphragm, the reinforcing ribs are pits with round cross sections, a conducting hole is formed in the center of the bottom of the end of one pit, and the conducting rod is connected with the vibrating diaphragm through the conducting hole. The vibrating diaphragm is simple in structure, the vibrating strength is higher on the premise that the thickness is not changed, the vibrating amplitude of the vibrating diaphragm is higher, the stability and smoothness of vibration of the vibrating diaphragm can be effectively guaranteed, and the sound quality of the telephone receiver can be effectively guaranteed. The vibrating diaphragm is connected with the conducting rod through the conducting hole, connection is convenient and firm, and a small space is occupied.

Description

technical field [0001] The invention specifically relates to a vibrating membrane and a receiver with a rib structure. 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 larger the vibrating range of the diaphragm,...

AI Technical Summary

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, when the diaphragm vibrates, it is likely to form a wave-shaped vibration, which will cause noise interference to the receiver
