Anti-coupling acoustic structure on refrigerator

Abstract

The invention discloses an anti-coupling acoustic structure on a refrigerator. The anti-coupling acoustic structure on the refrigerator comprises an installing panel used for being connected with a refrigerator door body or a refrigerator body, and an acoustic body; a plurality of through holes are formed in the installing panel; the acoustic body is arranged on the back face side of the installing panel; a gap exists between the acoustic body and the back face of the installing panel; and a surrounding and blocking part is arranged in the gap. According to the anti-coupling acoustic structure on the refrigerator, the acoustic body and the installing panel are arranged in a spaced manner, electrostatic coupling is not prone to happening when an electromagnetic compatibility experiment is performed on the refrigerator, the experiment precision can be guaranteed easily, meanwhile, it is avoided that the acoustic body and the installing panel resonate in the using process, and consequently the tone quality is affected, the surrounding and blocking part has the sound gathering effect, the directivity of sounds made by the acoustic body can also be improved, and a better listening effect is acquired.

Description

technical field [0001] The invention relates to the technical field of refrigerator manufacturing, in particular to an anti-coupling acoustic structure on a refrigerator. Background technique [0002] As a container that can keep food at a constant low temperature and cold state, a refrigerator has become one of the indispensable household appliances in modern families. With the rapid development of informatization, users have higher and higher requirements for intelligent refrigerators. [0003] One of the most important functions of a smart refrigerator is that it can perform human-computer interaction, and using the audio structure set on the refrigerator to play voice is an important means of human-computer interaction. [0004] The audio structure on the existing refrigerator includes an installation panel and an audio body, and the audio body is closely attached to the back of the installation panel, and is fixedly connected by buckles. [0005] Electromagnetic compa...

AI Technical Summary

Problems solved by technology

[0006] When doing electromagnetic compatibility experiments on refrigerators, it is necessary to apply static electricity from the surface of the installation panel to the sound structure. In the existing sound structure, the sound body is directly in contact with the back of the installation panel, and the sound body is too close to the surface of the installation panel, which is prone to electrostatic coupling and affects the experiment. Accuracy, not conducive to product testing

[0007] At the same time, the audio body is in direct contact with the installation panel, and the audio body tends to resonate with the installation panel during use, which affects the sound quality

[0008] In addition, because the sound structure on the existing refrigerator does not have a sound gathering structure, the sound emitted by the sound body is relatively divergent, and it is difficult to obtain a better listening effect
