WO2009018677A1 - An earcap for headphone - Google Patents

Abstract

An earcap for headphone, which is made from silica gel material and in the form of a cover body, comprises a body (2) and a cushion (4) that is arranged on the periphery of the body (2) and molded together with the body (2). The body (2) is smooth-faced and has several through-holes set on it. The cushion (4) has a protruded outer surface and a depressed inner surface. Since the body (2) and the cushion (4) are formed as one body and molded through injecting one time, the manufacturing process is simplified. And the manufacturing material is chosen from silica gel which is fit for a human body, so it meets the requirements of environmental protection, high temperature resistance, and it is difficult to burn, easy to clean and sanitize.

Description

 Earphone earmuffs

 The present invention relates to a earphone ear cover, and more particularly to a earphone ear cover using a silicone material. Background technique

 The existing earphone ear cover is made of synthetic leather or chemical fiber fabric wrapped sponge, and the processing technology is complicated, and the sponge and the chemical fiber fabric are flammable, which is not good for fire prevention. In addition, the sponge is easy to breed bacteria and is inconvenient to be disinfected. It is easy to absorb the sweat of the human body and the close contact with the human body may cause an allergic reaction to the human body. When the temperature is high, it is difficult to dissipate heat, and long-term use is not conducive to human health. Summary of the invention

 SUMMARY OF THE INVENTION An object of the present invention is to provide an earphone ear cover which is simple in structure, easy to handle and safe to wear.

 In order to achieve the above object, the technical solution adopted by the present invention is: a earphone earmuff, which is made of a silicone rubber material and has a cover shape, and includes a body and an ear art portion which is disposed on the periphery of the body and integrally formed with the body.

 The body has a smooth planar shape and is provided with a plurality of through holes. The ear pad portion has an annular shape, and is convexly disposed on one side of the body to have a C-shaped cross section. The ear pad portion defines a convex outer surface and a concave inner surface. The outer surface of the ear pad portion is provided with a plurality of slightly convex ribs, and the number of ribs are evenly distributed around the body, and the whole is radially striped. The surface of the ear pad portion is provided with a plurality of protrusions, and the protrusions are columnar, and are distributed around the body, and are arranged in an inner and outer direction.

 The body and the ear pad portion of the invention are integrated into one body, and can be formed by one injection, which simplifies the complicated processing technology; the manufacturing material is selected from the medical silicone material suitable for the human body, and is environmentally friendly, high temperature resistant, flame retardant and easy to clean, The invention has the advantages of easy disinfection; and has a unique radial stripe surface and an inner venting convex design. Therefore, the earphone ear cover of the present invention has a simple structure, is comfortable to wear, and is safe and practical.

For a better understanding of the features and the details of the present invention, reference should be made to the accompanying drawings. DRAWINGS Figure 1 is a schematic view of a earphone earphone of the present invention;

 Figure 2 is the main view of Figure 1.

 Figure 3 is a top view of Figure 1.

 Figure 4 is a side view of Figure 1;

 Figure 5 is a cross-sectional view of Figure 4

 The invention is described in detail below with reference to the accompanying drawings.

 As shown in FIG. 1-5, the earphone ear cover of the present invention is injection molded from a medical silicone material, and has a substantially cover shape, and includes a body 2 and an ear pad portion 4 which is disposed on the periphery of the body 2 and integrally formed therewith.

 The body 2 is a circular smooth plane on which a plurality of evenly distributed circular through holes 22 are provided to facilitate the transmission of sound from the through holes 22. The through hole 22 has a diameter of 2 mm.

 The ear pad portion 4 is annular, and is convexly disposed toward the side of the body 2 so as to have a C-shaped cross section, thereby forming a convex outer surface and a concave inner surface, and a slightly convex rib on the outer surface. 42, the number of ribs 42 is evenly distributed around the body 2, and is generally striped in shape. The inner surface of the ear pad portion 4 is provided with a plurality of protrusions 44, which are cylindrical and evenly distributed around the body 2, and are arranged in two inner and outer rings as a whole, and the protrusion 44 has a diameter of 1.5 mm.

 In use, the earphone ear cover is sleeved on the earphone body, the through hole 22 of the body 2 corresponds to the speaker sound hole, and the sound can be smoothly released, and the inner surface of the ear pad portion 4 of the earphone ear cover 4 makes the inner surface of the ear pad portion 4 and the earphone Spaces are formed between the bodies, and the protrusions 44 can be bent and extended, so that the ear pad portion 4 is more elastic and comfortable to wear; the protrusions 44 are formed with a gap to be well ventilated.

 The body and the ear pad portion of the invention are integrated into one body, and can be formed by one injection, and the complicated processing technology is barreled; the manufacturing material is selected from medical silicone materials suitable for the human body, and is environmentally friendly, high temperature resistant, flame retardant and easy to clean. And easy to sterilize; and, with a unique radial stripe surface and internal venting convex design, the earphone earmuff of the invention is simple in structure, comfortable to wear and safe and practical.

 In the above, various other changes and modifications can be made in accordance with the technical solutions and technical concept of the present invention, and all such changes and modifications should be included in the appended claims. The scope of protection.
