Telephone receiver with anti-collision and anti-throwing function

Abstract

The invention discloses a telephone receiver with an anti-collision and anti-throwing function. The telephone receiver comprises a shielding outer shell and a moving iron unit arranged in the shielding outer shell. The moving iron unit comprises an armature, magnets and coils. The inside faces, opposite to the armature, of the coils in the vertical vibration direction of the armature are respectively provided with at least a protruding part. The telephone receiver with the anti-collision and anti-throwing function has the anti-collision and anti-throwing function, is simple in manufacturing technology, wide in audio range and better in tone quality effect.

Description

technical field [0001] The invention relates to a receiver, in particular to a receiver with the function of anti-collision and drop resistance. 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 its own ...

Problems solved by technology

[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

[0004] In order to avoid the above situation, traditional earphones generally use a raised part on the armature to prevent the armature from being integrated with the magnet. Although such a setting can achieve a good effect, due to the distance between the magnet and the armature Smaller, its manufacturing process is more difficult; and it is easy to reduce the vibration amplitude of the armature, and the audio range of the receiver is also reduced, which affects the overall sound quality
