Embodiment 1

[0021] Embodiment 1: The molded body 100 adopts the tube-drawing process. The material of the tube is 304 stainless steel or 305 stainless steel. One end of the tube is shrunk inwardly. Fit it to the inner wall of the drawing tube, and then use the jig heating block to shape the damping cloth 500 to keep it close to the shape of the inner wall of the drawing tube. The other straight end of the drawing tube is processed after the damping cloth 500 is put into the drawing into contraction.

Embodiment 2

[0022] Embodiment 2: The same process as in Embodiment 1, the difference is that the two end surfaces of the drawing tube do not need to shrink inwardly, and the damping cloth 500 is put into the drawing tube, and the ring with the same inner diameter as the drawing tube is used to press down and fix the damping Cloth 500.

Embodiment 3

[0023] Embodiment 3: as image 3 As shown, the molded body 100 adopts an injection molding process, and the damping cloth 500 is fixed by a plastic buckle. The shape of the buckle is shown in the schematic diagram. .

Abstract

The invention discloses a tunable acoustic damping and belongs to the technical field of acoustics. The tunable acoustic damping comprises a molding body, wherein the molding body is of a pipeline structure; damping cloth is arranged on the inner wall of the pipeline structure; the damping cloth is capable of simultaneously covering at least one circular end face of the molding body; and the damping cloth is of a grid-like structure. The acoustic damping is capable of weakening harsh or loud sounds from the sound source, so that the sound is soft when transmitted to listener's ears. The tunable acoustic damping disclosed by the invention is simple in structure, high in practicality and wide in application field.

Description

technical field [0001] The invention relates to an acoustic damping, in particular to an adjustable acoustic damping. Background technique [0002] The sound emitted by the acoustic equipment will change with the change of the sound source. If the sound transmitted to the user's ear by the receiver or the speaker is too high-pitched or the noise is loud, it will make the user feel very uncomfortable. For such a situation, the purpose of adjustment is generally achieved by reducing the volume of the acoustic equipment, but this adjustment method will not be very timely, and the user will only adjust when they hear the noise, and the adjustment is relatively meaningless. There is little protection for the user. If acoustic damping is installed at the place where the receiver or speaker emits sound, when the sound is too harsh, the damping can improve the tone in real time, control the tone at the source of sound propagation, and send soft sound to the user's ear, which can pl...
