Abstract

The invention relates to a loudspeaker and belongs to the technical field of loudspeakers. Including a mesh cover, a bracket and a U cup, the mesh cover and the bracket are matched and connected to each other to form a whole, the U cup is clamped at the bottom of the bracket, a sound membrane is installed in the mesh cover, and the bottom surface of the sound membrane is provided with A rectangular piezoelectric ceramic sheet, the bottom of the piezoelectric ceramic sheet is cemented with a grooved voice coil that runs through up and down, and a rectangular U-cup mounting port is also opened on the bottom surface of the bracket, and the U-cup mounting port is snap-fitted and installed. U cup, the top surface of the U cup is also provided with a magnetic slot for installing the washer, the top surface of the washer is provided with a secondary magnetic slot, and a secondary magnet is glued and installed inside the secondary magnetic slot. There is also a main magnet glued to the bottom surface of the company, and the bottom surface of the main magnet is glued in the magnetic groove of the U cup. The loudspeaker of the invention solves the problem of difficult assembly of the loudspeaker, simultaneously solves the technical problems of magnetic flux leakage and nonlinear distortion, and has low production cost, high production efficiency, high finished product qualification rate and excellent acoustic performance.

Description

technical field [0001] The invention relates to a loudspeaker and belongs to the technical field of loudspeakers. Background technique [0002] The speaker is a sound output device in which the electrical signal output from the audio amplifier is converted into the vibration of the vibration unit, which generates density waves in the air, thereby generating sound waves. According to the working principle of the speaker, the speaker is classified into different types such as magnetic speaker, dynamic speaker, electrostatic speaker, piezoelectric speaker and ceramic speaker. [0003] In the prior art, the loudspeaker includes: a magnetic circuit unit including a magnet for generating magnetic flux, a yoke portion for providing a path for the magnetic flux; and a bobbin (bobbin) wound with a voice coil; a frame (frame) and a vibrometer including a diaphragm vibrating according to the movement of the bobbin, a damper for adjusting the vibration direction of the diaphragm, and a...
