Description

Technical Field

[0001] The invention belongs to the technical field of electronic products, and in particular relates to an earphone pad and a manufacturing method thereof. Background Art

[0002] In the field of audio equipment, headphones are widely used to provide a personalized listening experience. Headphones include two left and right housings containing speakers, which are placed close to the user's ears to directly transmit sound. In order to improve comfort and prevent the housing from directly contacting the user's ears, headphones are usually equipped with earphone pads. These earphone pads play a role of buffering and sealing, effectively reducing sound leakage, improving sound quality, and reducing the discomfort that may be caused by long-term use of headphones.

[0003] The current earphone pad design usually includes an annular pad and a coating layer coated on the surface of the annular pad. This design provides a good cushioning effect, but it also requires additional fixings to fix the annular pad and the coating layer together. For example, publication number CN114390386A discloses an earphone cover and an assembly method thereof, including an annular fixing, a cylindrical and elastic surface layer, and an annular buffer, wherein the fixing is connected to one end of the surface layer, and the other end of the surface layer passes through the central opening of the buffer and is connected to its own other end or the fixing to form a circular ring-shaped structure covering the buffer. This design not only increases the production complexity of the earphones, but may also affect the service life of the earphones. For example, if the fixing is not suitable or degummed due to excessive use, the coating may become loose, affecting the overall stability of the earphone pad and reducing the user experience.

[0004] Therefore, there are areas that need to be improved and optimized in the design and manufacture of earphone pads. An ideal earphone pad should have a stable structure, and at the same time, it should also have a simplified design and manufacturing process to reduce production costs and complexity. Summary of the invention

[0005] The technical problem to be solved by the present invention is: to provide an earphone pad and a manufacturing method thereof in view of the problem that the covering layer of the earphone pad in the prior art is easy to loosen due to the possibility of debonding of the fixing parts during use.

[0006] To solve the above technical problems, on the one hand, an embodiment of the present invention provides an earphone pad, including an annular cushion and an elastic surface layer, wherein the elastic surface layer has an annular cavity adapted to the annular cushion, and the annular cushion is located inside the cavity.

[0007] Optionally, the annular cushion is a sponge.

[0008] Optionally, the elastic surface layer is polyester.

[0009] On the other hand, another embodiment of the present invention provides a method for manufacturing an earphone pad, comprising the following steps:

[0010] Prepare a cylindrical polyester fabric and an annular profiling block for molding the cylindrical polyester fabric, wherein the annular profiling block has a plurality of positioning bosses;

[0011] One end of the cylindrical polyester cloth is passed through the positioning boss and fixed to the annular profiling block, and the other end is passed through the central opening of the annular profiling block, and then the annular profiling block is turned around along the surface of the annular profiling block, and is also passed through the positioning boss and fixed to the annular profiling block, so that the cylindrical polyester cloth completely covers the annular profiling block;

[0012] Putting the shaped block covered with the cylindrical polyester cloth into an oven for baking, and taking out the annular shaped block after baking to obtain a shaped polyester, wherein the shaped polyester has an annular cavity of the same size as the annular shaped block;

[0013] Prepare a ring-shaped sponge of the same size as the ring-shaped block;

[0014] The ring-shaped sponge is stuffed into the ring-shaped cavity of the molded polyester to obtain the earphone pad.

[0015] The earphone pad provided by the embodiment of the present invention only includes an annular software layer and an elastic surface layer. Compared with the traditional earphone pad, this earphone pad avoids the use of additional fixing parts, thereby reducing the complexity and avoiding the possibility of the coating layer loosening. The present invention provides a method for making an earphone pad. Through the cylindrical polyester cloth and the annular profiling block, an earphone pad with a desired shape can be simply and effectively made, without the need for complicated equipment and processes, the production process is simple, and the production cost is relatively low.
