Problems solved by technology

This kind of earmuffs must be frozen in the refrigerator before use, in order to have a good heat absorption effect, so that the wearer will not feel stuffy, but this kind of earmuffs is very inconvenient to use, if there is no refrigerator Occasionally, it will not be frozen in advance and will not have the effect of absorbing heat and cooling down

Embodiment 1

[0021] Such as figure 1 and figure 2 Commonly shown, a kind of cooling and sealing cover-type earmuffs for acoustic products is a ring-shaped structure, including a ring-shaped outer lining 10 with one side open. The opening of the outer lining 10 is combined with a backsheet 20. It is a ring-shaped sheet, the outer liner 10 and the back sheet 20 are pasted together, and the closed space surrounded by the outer liner 10 and the back sheet 20 is provided with a filler 30 . The bottom sheet 20 is combined with the earphone body.

[0022] Such as image 3 As shown, the outer lining 10 is made of a heat-conducting silica gel layer, and the thickness of the heat-conducting silica gel layer is preferably between 0.1 mm and 1 mm. The filler 30 is foam, sponge, memory foam or silica gel. Thermally conductive silicone has the formability of solid substances and the flexibility and fluidity of liquid substances, so it can automatically fill the uneven skin structure around the huma...

Embodiment 2

[0025] Such as Figure 4 As shown, this embodiment is basically the same as Embodiment 1, the difference is:

[0026] The filler 30 is heat-conducting silica gel, the outer liner 10 is a fabric or leather material outer liner, and the outer liner 10 and the backsheet 20 are thermally pressed and pasted together.

Abstract

The invention discloses a temperature-reducing seal cover type earmuff for acoustic products, and relates to the technical field of acoustic products contacted with human ears. The earmuff is an annular structure and comprises an annular outer lining with an opening at one side, the opening of the outer lining is combined with an annular base piece, a filler is arranged in the closed space surrounded by the outer lining and the base piece, and the outer lining is a heat conducting silica gel layer or the filler is a heat conducting silica gel. The temperature-reducing seal cover type earmuff for the acoustic products solves the problems of poor sealing property and radiating property of the existing earmuff used for the acoustic products, not only meets the requirement of high standard acoustic sealing, but also is good in radiating effect and light in weight, so people cannot feelings of sultriness or press after long-term wearing.

Description

technical field [0001] The invention relates to the technical field of acoustic products in contact with human ears, in particular to a cooling and sealing cover earmuff for acoustic products. Background technique [0002] Earphones are personal audio. With the rapid development of the electronic industry, there are more and more types of earphones, which can be divided into four types: earplugs, ear-hanging, in-ear and head-mounted in terms of wearing styles. Wherein, the earphone is provided with earmuffs that are in close contact with the skin around the human ear, and the earmuffs form a sealed space between the earphone and the human ear, which can block the entry of external sounds. [0003] There are two main types of earmuffs currently on the market for earphones: [0004] The first type: use foam as the inner filler, and use leather or fabric as the outer lining. This kind of earmuffs has poor sealing performance and is difficult to meet the requirements of high a...
