Problems solved by technology

[0013] Due to the uneven viscosity of the liquid adhesive used in assembly processing, it is difficult to quantitatively control the amount of adhesive sprayed from the adhesive applicator, and it is difficult to adjust the adhesive coating according to the viscosity of the adhesive. The air ejection pressure of the cloth machine has great difficulties in process management
[0014] In addition, as mentioned above, due to the difference in the air ejection pressure of the adhesive applicator and the viscosity and coating amount of the adhesive, it is difficult to stick the structural parts of the speaker to have a certain adhesive force, so the quality of the speaker Deviation
[0015] In addition, the binder includes various harmful substances and thus is also a cause of environmental pollution.

Abstract

The present invention relates to a microspeaker, comprising: a frame; a vibration diaphragm, the outer periphery of which is fixed at the frame; a voice coil fixed at the lower surface of the vibration diaphragm; a resilient suspension, the outer periphery of which is fixed at the frame; a yoke fixed at the suspension; a permanent magnet fixed at the inner bottom surface of the yoke; and a plate fixed at the upper surface of the permanent magnet, wherein the pair of the frame and the vibration diaphragm, the pair of the yoke and the permanent magnet, and / or the pair of the permanent magnet and the plate are coupled together by a bonding film.

Description

technical field [0001] The present invention relates to a microspeaker, and more particularly to a microspeaker capable of simplifying the assembly process and improving productivity by combining various parts with an adhesive film when manufacturing and processing the microspeaker. Background technique [0002] In general, a loudspeaker is a device that converts electrical signals into acoustic signals. Microspeakers are mainly used in small-sized audio equipment, such as mobile phones, notebook computers, MP3 players, earphones, etc. Recently, the demand for small speakers for portable audio equipment has increased greatly. [0003] However, most of the latest electronic products using micro-speakers, especially mobile communication terminals such as mobile phones, have structures that generate vibration signals. Such a vibration signal is used as a signal instead of receiving a signal tone, or as a signal for confirming an input state in a touch panel method of directly ...
