Novel telephone receiver with anti-collision function and anti-vibration function

Abstract

The invention discloses a novel telephone receiver with an anti-collision function and an anti-vibration function. The telephone receiver comprises a shielding shell, a magnetic force drive mechanism, a vibrating film and a conduction rod, wherein the magnetic force drive mechanism, the vibrating film and the conduction rod are arranged in the shielding shell. The magnetic force drive mechanism comprises an armature, a magnet, a coil and an iron core, the coil and the iron core are sequentially arranged on the armature in a sleeving mode, the two ends of the conduction rod are connected with the free end of the armature and the vibrating film respectively and in the upward and downward vibrating direction of the vibrating film, first protrusion portions are arranged on the two inner walls, opposite to the armature, of the iron core, the magnet is disposed on the inner wall of the iron core, and second protrusion portions are formed at the positions corresponding to the first protrusion portions. By the adoption of the novel telephone receiver with the anti-collision function and the anti-vibration function, on the premise that sound quality of the telephone receiver is not affected, the anti-collision function and the anti-vibration function can be achieved, use environments are more flexible, and service life is prolonged.

Description

technical field [0001] The invention relates to the field of receivers, in particular to a new receiver with anti-collision and anti-vibration functions. 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. [0003] However, when people use devices such as mobile phones, fixed phones, and earphones, they often cause relatively large impacts on the receivers in these devices in some environments. When used in a large and harsh environment, the impact often affects the armature in the receiver, causing the receiver to fail to work properly. This is because the armature is an important part of the drive device in the receiver. It drives the diaphragm in the receiver to vibrate through...

[0003] However, when people use devices such as mobile phones, fixed phones, and earphones, they often cause relatively large impacts on the receivers in these devices in some environments. When used in a large and harsh environment, the impact often affects the armature in the receiver, causing the receiver to fail to work properly

This is because the armature is an important part of the drive device in the receiver. It drives the diaphragm in the receiver to vibrate through its own vibration to transmit sound, and if the armature is subject to a large impact, the armature is very It is easy to be attracted to the magnet upward or downward, which will cause the armature to fail to vibrate and make it invalid, so that the diaphragm cannot continue to vibrate, so that the entire receiver cannot work properly
