Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically to duplex headphones. Background Technology

[0002] Headphones are portable audio devices that convert electrical signals into sound waves. They are mainly used for personal listening and are usually connected via wired or wireless means. Duplex headphones are a type of headphone that supports two-way communication, has large earcups and an adjustable headband, and provides clear sound and good noise isolation.

[0003] Currently, headphones still have some shortcomings, such as water entering the earpiece when worn in water.

[0004] To overcome the problem of poor waterproof performance of headphones, a Chinese patent (publication number: CN207235048U) discloses a waterproof headphone. By pressing the earcups of the headphone, air from the air-absorbing bag is expelled through the suction holes. This allows the air-absorbing bag to adhere to the skin of the wearer's ear through the suction holes under negative pressure, thereby improving the waterproof performance of the headphone earcups and avoiding changes in inner ear pressure caused by the negative pressure adsorption of the air-absorbing bag, thus protecting the inner ear.

[0005] However, the headphones currently in use still have some shortcomings. The document mentioned above states that by expelling air from the headphone cover, the negative pressure can be reduced and the waterproof effect of the headphones can be improved. However, if the seal is not good enough, small water droplets and moisture may still enter the headphone. Secondly, the earcups of the headphones are prone to stains after wearing them for a long time, which is troublesome to clean. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this invention is to provide a dual-mode over-ear headphone to solve the problems mentioned in the background art, such as poor headphone sealing, which can affect headphone sound quality, and the inconvenience of replacing headphone foam pads.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a duplex headset, including a headband, with a headset body connected to the bottom of the headband, a sponge pad connected to the side of the headset body, and a microphone installed on the side of the headset body away from the sponge pad.

[0008] The earphone body has a fixing ring inside, and two placement grooves are opened inside the fixing ring. A waterproof membrane and a waterproof mesh are respectively connected inside the placement grooves. The waterproof mesh is close to the sound outlet of the earphone body. The fixing ring is provided with a sealing mechanism to improve the waterproof effect of the earphone.

[0009] The surface of the fixing ring is provided with an L-shaped groove, and a fixing block is fixed to the side of the sponge pad near the headphone body. The L-shaped groove is provided with a disassembly and assembly mechanism for replacing the sponge pad.

[0010] Furthermore, the sealing mechanism includes an airbag ring, which is connected inside two mounting grooves, and the two airbag rings are respectively attached to the sides of the waterproof mesh and the waterproof membrane.

[0011] Furthermore, an installation groove is provided on the side of the placement groove, and a miniature air pump is installed inside the installation groove. The output end of the miniature air pump is connected to a connecting pipe, which is connected to the side of the airbag ring.

[0012] Furthermore, the disassembly and assembly mechanism includes a sliding block, which is fixed around the inside of the fixed block. The sliding block and the L-shaped groove are provided with six sets, and the sliding block has a telescopic groove on its side.

[0013] Furthermore, a compression ball slides inside the telescopic groove, and a spring connects the compression ball to the telescopic groove.

[0014] Furthermore, a positioning groove is provided on the side of the L-shaped groove, the positioning groove is engaged with the extrusion ball, and the sliding block is slidably connected with the L-shaped groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this dual-mode headset, the airbag ring expands inside the mounting groove after being supplied with gas. When the airbag ring expands, it can squeeze the side walls of the waterproof membrane and waterproof mesh, improving the sealing effect of the headset body.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1, such as Figures 1-4The technical solution shown in this utility model provides the following solution: To solve the problem of poor headphone sealing, and that a high level of sealing affects headphone sound quality, a sealing mechanism is disclosed: including a headband 1, with a headphone body 2 connected to the bottom of the headband 1, a sponge pad 3 connected to the side of the headphone body 2, and a microphone 4 installed on the side of the headphone body 2 away from the sponge pad 3; a fixing ring 201 is connected inside the headphone body 2, and two mounting grooves 202 are formed inside the fixing ring 201, with a waterproof membrane 203 and a waterproof mesh fabric 204 respectively connected inside the mounting grooves 202, providing waterproofing. The mesh fabric 204 is located near the sound outlet of the headphone body 2. The fixing ring 201 has a sealing mechanism inside to improve the waterproof effect of the headphone. The sealing mechanism includes an airbag ring 205, which is connected to the inside of two mounting slots 202. The two airbag rings 205 are respectively attached to the sides of the waterproof mesh fabric 204 and the waterproof membrane 203. The mounting slot 206 is provided on the side of the mounting slot 202. A miniature air pump 207 is installed inside the mounting slot 206. The output end of the miniature air pump 207 is connected to a connecting pipe 208, which is connected through to the side of the airbag ring 205.

[0029] During use, the miniature air pump 207 can be activated. When activated, the miniature air pump 207 delivers gas to the two airbag rings 205 through the connecting tube 208. After being delivered gas, the airbag rings 205 expand inside the mounting groove 202. When the airbag rings 205 expand, they can compress the side walls of the waterproof membrane 203 and the waterproof mesh 204. When the airbag rings 205 compress, the water vapor and water droplets encountered by the headphones will not enter the headphone body 2 through the side of the waterproof mesh 204 and the waterproof membrane 203, thereby improving the sealing effect of the headphone body 2. Furthermore, when the miniature air pump 207 is not running, the compression strength of the airbag rings 205 on the waterproof membrane 203 and the waterproof mesh 204 is limited. The limited compression can increase the gap between the waterproof membrane 203, the waterproof mesh 204 and the mounting groove 202, which can indirectly improve the sound transmission of the headphone body 2, thereby enhancing the headphone sound effect. The sealing of the headphone body 2 can be changed according to the needs of the usage environment, improving the convenience of headphone use.

[0030] Example 2, as follows Figure 2 , Figure 5 and Figure 6The present invention provides the following technical solution to address the problem of inconvenient replacement of the earphone's foam pad 3, which affects hygiene and safety: a disassembly and assembly mechanism is disclosed. An L-shaped groove 210 is provided on the surface of the fixing ring 201. A fixing block 211 is fixed to the side of the foam pad 3 near the earphone body 2. A disassembly and assembly mechanism for replacing the foam pad 3 is provided inside the L-shaped groove 210. The disassembly and assembly mechanism includes a sliding block 212, which is fixed around the inner side of the fixing block 211. Six sets of sliding blocks 212 and L-shaped grooves 210 are provided. A telescopic groove 213 is provided on the side of the sliding block 212. A compression ball 214 slides inside the telescopic groove 213. A spring connects the compression ball 214 to the telescopic groove 213. A positioning groove 215 is provided on the side of the L-shaped groove 210. The positioning groove 215 and the compression ball 214 form a locking connection, and the sliding block 212 and the L-shaped groove 210 form a sliding connection.

[0031] The earphone's foam pad 3, after prolonged use, will show wear and stains and needs replacement. Rotating the foam pad 3 will cause the fixing block 211 to rotate. When the fixing block 211 rotates, it will cause the sliding block 212 to rotate. When the sliding block 212 rotates, it will cause the telescopic groove 213 to press against the inner wall of the positioning groove 215. After being pressed, the compression ball 214 can slide through the telescopic groove 213. As the compression ball 214 slides, it can compress the spring inside the telescopic groove 213. After the compression ball 214 is forced out of the positioning groove 215, the sliding block 21... 2. The sliding block 212 can slide through the L-shaped groove 210. When the sliding block 212 slides, the fixed block 211 can rotate on the surface of the fixed ring 201. When the sliding block 212 rotates to the side of the L-shaped groove 210 away from the positioning groove 215, it can pull the sponge pad 3 outward. When the sponge pad 3 is pulled, it can drive the sliding block 212 to slide out of the L-shaped groove 210. At the same time, the fixed block 211 will also slide out of the surface of the fixed ring 201. At this time, the sponge pad 3 and the headphone body 2 will be separated and disassembled. After disassembly, a new one can be replaced, which further improves the convenience of using the headphone.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
