Receiver with novel shielding case

Abstract

The invention discloses a receiver with a novel shielding case. The receiver comprises a bottom case, an upper cover, a sound production tube, an electromagnet drive device arranged in a cavity formed by the bottom case and the upper cover, and a vibration film component, wherein the shielding case is arranged on the bottom case and the upper cover, and the connection position of the bottom case and the upper cover is sealed by the shielding case. The receiver with the novel shielding case is simple in structure and magnetic leakage can be effectively reduced, besides the gap between the bottom case and the upper cover can be effectively sealed by the shielding case arranged on the bottom case of the receiver and the upper cover, thus magnetic leakage is prevented, magnetic interference is absent from the sound production tube of the receiver and the sound quality is ensured.

Description

technical field [0001] The invention relates to a receiver, in particular to a receiver with a novel shielding shell. Background technique [0002] Receivers or hearing aids can receive signals in a variety of ways. With the development of science and technology, the transmission of Bluetooth functions has gradually become common. The coil is generally closer to the loudspeaker device, such as a sounding tube. The magnetism of magnetic flux leakage affects the speaker device, and it is easy to generate howling and noise in the receiver or hearing aid, which affects the use of the user. [0003] When the upper cover and the housing of the receiver are assembled, electric welding is usually used for welding, and glue is used for bonding after welding. Although this connection method is fast, because the electric welding method can only form a connection point on the outer edge of the connection surface between the upper cover and the shell, it is easy to cause magnetic flux ...

AI Technical Summary

Problems solved by technology

Although this connection method is fast, because the electric welding method can only form a connection point on the outer edge of the connection surface between the upper cover and the shell, it is easy to cause magnetic flux leakage. It will affect the movement of the vibrating armature inside it, reducing the stiffness of the vibrating armature, thus affecting the use effect
