Description

Elastic wave with local elastic support structure

This creation is related to a kind of elastic wave structure used for a horn, especially a kind of elastic wave with a partial elastic support structure.

According to the general speaker or speaker, the non-metallic parts contained in the interior of the speaker are made of cloth. The main reason is that the specially treated cloth has the appropriate elasticity and strength, and can provide the speaker or speaker to operate. Functional requirements, such as drum paper, elastic waves, connecting sheets, etc., are all true. Among them, Damper is one of the most important components in the speaker or speaker structure. The elastic wave is an elastic support between the outer frame and the voice coil. Its main function is when the vibrating piece vibrates. Provides the repetitive force required for the voice coil to vibrate, and restrains the displacement of the voice coil in the horizontal direction, making the vibration process of the voice coil more stable. Therefore, in addition to providing better output power and audio characteristics of the speaker or speaker, the elastic wave is also the basis for the quality control of the speaker or speaker manufacturer when manufacturing the speaker or speaker.

A method for manufacturing a conventional elastic wave, which comprises an impregnation step, a baking step, a hot pressing step, and a cutting step. Wherein, the impregnation step impregnates the fabric with the resin, so that the cloth absorbs the resin, and a resin layer is formed on the outside of the fiber of the cloth, so that the cloth has a certain hardness. The baking step dries the resin-absorbent fabric to remove moisture from the fabric. The hot pressing step heats the cloth absorbing the resin and forms a wave-like shape in the cross section by embossing. The cutting step forms a central through hole, cuts into a plurality of elastic waves, and removes excess cloth.

Further, the elastic wave produced by the above-mentioned conventional technique has the following drawbacks: First, the hardness of the entire elastic wave is the same, and the resin after drying is hard and the elasticity is poor. Second, when the elastic wave is used for a long time, the resin is subjected to vibration, fatigue stress, heat and the like, which may cause problems such as hardening and aging. Thirdly, since the material of the resin is different from that of the fabric, it is easy to resonate with the vibration frequency of the fabric, and there are many noises, low-frequency channels are not easy to appear, the load rebounding ability is poor, and the sound quality is poor.

Therefore, after observing the above-mentioned missing, the creator of the case believes that the conventional elastic wave structure still needs further improvement, and there is no such creation.

The main purpose of the present invention is to provide a spring wave having a partial elastic support structure, which is mainly provided through the elastic support portion to form a partial elastic and airtight elastic wave, and provides a vibration of the elastic wave relative to the voice coil. Support, so that the elastic wave has superior fatigue resistance.

Preferably, the body is provided with at least two elastic supporting portions selected from one or a combination of the two side surfaces of the body.

Preferably, the elastic supporting portions are linearly disposed in a radial direction of the body.

Preferably, wherein the elastic support portions form at least two linear arrangements.

Preferably, the area of the elastic support portion is greater than, equal to, or smaller than the area of the gas permeable region.

Preferably, the body is provided with a plurality of the elastic supporting portions, and the elastic supporting portions are spaced apart from each other at the second block.

Preferably, wherein the elastic support portions are disposed around the perforations.
