Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a sports head-mounted earphone. Background Art

[0002] Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. Headphones can be separated from the media player so that you can listen to the audio alone without disturbing others.

[0003] Headphones, as the name implies, are worn on the head, not inserted into the ear canal. They are different from in-ear earplugs. In the prior art, the headphone is hung on the top of the user's head with a headband and clamped on the sides of the user's ears with two earmuffs, thereby achieving the positioning of the headphone and the user's head.

[0004] However, existing sports headphones are equipped with filters when in use. The filters are used to isolate the sound-generating mechanism and the ear canal. Since sweating occurs during exercise, the filters are easily soaked by sweat. If they are not cleaned, the filters will be affected by dust and debris, which will affect the output of the headphones. However, most of the existing filters are integrated with the headphones, making it difficult to disassemble and clean the filters, which is not convenient for later maintenance. Utility Model Content

[0005] The purpose of the utility model is to provide a sports headset to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sports head-mounted headset, comprising a wearing bracket, an earpiece and a mesh tube, wherein earpieces are arranged at both ends of the wearing bracket, a mesh tube is arranged on the inner side of the sound channel of the earpiece, a filter is arranged on the inner side of the mesh tube, the mesh tube is fitted with the inner wall of the sound channel, a cylindrical groove is provided on the side of the sound channel, a movable block is slidably connected in the cylindrical groove, a pull rod and a positioning rod are fixed on the movable block, the end of the pull rod passes through the side wall of the earpiece and is connected with the pull block, and a tension spring is sleeved on the outer side of the pull rod, the two ends of the tension spring are respectively connected to the movable block and the inner wall of the cylindrical groove, a fixed socket adapted to the positioning rod is provided on the side wall of the mesh tube, the positioning rod is inserted in the fixed socket to limit the mesh tube, and the mesh tube is limited by setting the positioning rod. When the mesh tube needs to be removed to maintain the filter, it only needs to pull the pull block and pull the positioning rod out of the fixed socket through the pull rod to cancel the restriction of the mesh tube, and then it can be taken out from the sound channel of the earpiece.

[0007] Preferably, a microphone is provided on the earpiece at one end of the wearing bracket, and the microphone is provided for recording the user's voice.

[0008] Preferably, a sound insulation sponge is provided on the outside of the sound channel of the earpiece, which can improve comfort and prevent sound leakage.

[0009] Preferably, a plurality of limit blocks are arranged on the outer side wall of the mesh tube, and a limit groove matched with the limit block is arranged on the inner wall of the sound channel of the earpiece, and the limit block is inserted in the limit groove. The limit block and the limit groove mainly play a limiting role.

[0010] Preferably, an elastic frame is arranged on the outside of the wearing bracket, and the elastic frame is arranged to improve the rebound effect so as to facilitate clamping on the user's head.

[0011] Preferably, a sponge pad is provided on the inner side of the wearing bracket to improve wearing comfort.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model sets the filter in the mesh cylinder and limits the mesh cylinder by the positioning rod. When the filter needs to be maintained, the positioning rod can be pulled out from the fixed socket by the pull rod to cancel the restriction of the mesh, so that the mesh cylinder can be removed for maintenance. When installing, the positioning rod can be pushed into the fixed socket by the tension spring to limit the mesh cylinder again. The operation is simple and easy to understand, which effectively improves the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
