Abstract

The invention provides a receiver, and relates to the technical field of receivers. The receiver is provided with an upper cover, a base frame, a diaphragm, a voice coil and a magnetic circuit unit, the diaphragm is adhesively fixed between the upper cover and the base frame, and the upper cover and the base frame are thermally melted, the voice coil is adhesively fixed to a lower surface of the voice coil, the magnetic circuit unit comprises a magnet, a pole core supported on the upper surface of the magnet and a magnet yoke connected to the lower surface of the magnet and forming a magneticgap with an outer circumferential surface of the pole core, the magnet has a first magnet portion and a second magnet portion protruding from the first magnet portion, the pole core is an annular polecore, and the annular pole core is supported on the upper surface of the first magnet portion is sleeved on the outer periphery of the second magnet portion.

Description

technical field [0001] The present invention relates to the technical field of receivers, in particular to a receiver. Background technique [0002] The receiver, also known as the handset, 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, landline phones, and earphones to realize audio, such as voice and music. replay. Its working principle is that the changing audio electrical signal is fed into the voice coil of the receiver, which is placed in the magnetic gap of a permanent magnet magnetic circuit, and the changing Ampere force (Lorentz force) produced by the voice coil due to the changing current ) is driven to vibrate up and down, and drives the diaphragm to drive the front and rear air to generate sound waves. [0003] The volume and power of the receiver are smaller than that of the speaker. The working efficiency of the receiver...
