Problems solved by technology

This assembly method has the following problems: (1) The efficiency of artificially attaching the sound-absorbing cotton is low, and the labor cost is high; (2) The material of the sound-absorbing cotton itself is relatively soft and easily damaged. , it is easy to cause damage to the sound-absorbing cotton and affect the use effect of the sound-absorbing cotton
(3) When the sound-absorbing cotton is attached manually, the consistency of the position of the sound-absorbing cotton is poor, which is likely to cause the deviation of the consistency of the acoustic performance

Abstract

The invention discloses a material component, a forming method and an assembly method of the material component, and a sound production device module. The material component comprises a bottom film provided with a through hole; a double faced adhesive tape adhered on the bottom film; a soft material piece, wherein the cross sectional area of the soft material piece is greater than that of the through hole, and the soft material piece is adhered on one side face of the bottom film through the double faced adhesive tape and covers the through hole; and a hard supporting piece, wherein the hard supporting piece is located in the through hole and is adhered on one side face of the double faced adhesive tape away from the soft material piece. One problem to be solved in the invention is that the efficiency of the existing manual assembly method of the soft material piece is low.

Description

technical field [0001] The present invention relates to the technical field of automation, and more specifically, the present invention relates to a material component, a forming method, an assembling method thereof, and a sounding device module. Background technique [0002] The speaker module is an important acoustic device of portable electronic equipment, which is used to complete the conversion between electrical signals and acoustic signals, and is an energy conversion device. The speaker unit divides the entire module cavity into two cavities, the front cavity and the rear cavity. In the rear acoustic cavity, some materials that can improve the acoustic performance can be properly filled, such as sound-absorbing cotton. Sound-absorbing cotton can reduce the low-frequency resonance frequency of the speaker module, improve low-frequency sensitivity, improve harmonic distortion, and improve audio. [0003] At present, one side surface of the sound-absorbing cotton is a...
