Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of headphones, and in particular to a noise reduction headphone with an anti-slip function. Background Art

[0002] Headphones, as the name implies, are worn on the head, not inserted into the ear canal, and are different from in-ear earplugs. They consist of two parts, a signal transmitter and headphones with signal receiving and amplifying devices. The transmitter is connected to the signal source, and a preamplifier or headphone amplifier can also be connected in front of the transmitter to improve the sound quality and adjust the timbre.

[0003] In the prior art, headphones mainly include a headband and earmuffs. When in use, the headband is hung on the top of the head, and the earmuffs are attached to the outside of the ears, forming a cavity between the earmuffs and the ears. The top headband is hung on the top of the user's head and the two earmuffs are clamped on the sides of the user's ears, thereby achieving positioning of the headphone and the user's head. However, compared with in-ear headphones, the headphone is heavier. When the user uses the headphone, the headphone is easily tilted forward and backward with the user's head and falls off, which is inconvenient to use and reduces the user's comfort. The headphones are also easily damaged.

[0004] A filter is provided in the earmuff of the existing headphone to isolate the sound-generating mechanism and the ear canal. The filter can not only filter the sound, but also prevent external dust and debris from entering the sound-generating mechanism. On the one hand, it protects the electronic components in the earphone from damage, and on the other hand, it ensures the purity of the sound quality output by the earphone. However, the filter is often in direct contact with the ear and is fixedly connected to the earmuff, which is difficult to disassemble and clean. The adhesion and accumulation of dust and debris will not only affect the output sound effect of the earphone, but may even cause redness, swelling and inflammation of the ear, affecting the health of the ear. Summary of the invention

[0005] To this end, an embodiment of the present invention provides a noise reduction headphone with an anti-slip function. Through the setting of the anti-slip component, the cavity formed between the earmuff and the ear can be locked by the fan-shaped plate, so that the headphone is prevented from detaching from the user's head and tilting and falling off. The structure is simple and easy to use, which increases the user's comfort, prevents the earphone from being dropped, and prolongs the service life of the headphone. Through the setting of the disassembly component, the sleeve connection of the pulley, the pressure piece and the transmission belt is linked, and the card block can be controlled to lock and loosen the positioning ring, so as to control the installation and disassembly of the filter net, so that the filter net is easy to be disassembled and cleaned, and dust and debris are prevented from being attached and accumulated, and the cleanliness of the filter net is ensured, so that the output sound effect of the earphone is good, and the health of the ear is protected at the same time, so as to solve the problem in the prior art that due to the heavy weight of the headphone, it is easy to tilt forward and backward with the user's head during use and fall off, which easily causes the earphone to be damaged, is inconvenient to use, and reduces the user's comfort. The filter net in the earmuff is often in direct contact with the ear and is fixedly connected to the earmuff, which is difficult to disassemble and clean.

[0006] In order to achieve the above-mentioned object, the embodiment of the present invention provides the following technical solution: a noise reduction headphone with anti-slip function, comprising a body, wherein the lower inner wall of the body is fixedly connected to two ear-covering compartments, and the inside and outside of the two ear-covering compartments are respectively installed with an anti-slip component and a disassembly component;

[0007] The anti-slip assembly includes an internal gear, seven driven gears are equidistantly connected to the housing through bearings, the front walls of the seven driven gears are meshed with a transmission rack, the outer wall of the internal gear is provided with arc-shaped teeth, and the front wall of the arc-shaped teeth is meshed with a driving gear;

[0008] The disassembly and replacement assembly includes a rotating shaft, a pulley is fixedly sleeved on the outer wall of the rotating shaft, a guide bolt is fixedly connected to the upper and lower ear bins of the pulley, five reference shafts are fixedly connected at equal intervals inside the outer ear bin, pressure pieces are rotatably sleeved on the outer walls of the five reference shafts, linkage frames are fixedly connected to the outer walls of the inner ends of the five pressure pieces, a clamping block is fixedly connected to the outer ends of the pressure pieces, a transmission belt is fixedly connected between the inner walls of the five linkage frames, and a second friction roller is fixedly sleeved on the inner outer wall of the rotating shaft.

[0009] Furthermore, transmission grooves are formed at the inner ends of the two sleeve ear bins, the internal gears are rotatably connected in the transmission grooves, and the seven driven gears are rotatably connected in the transmission grooves.

[0010] Furthermore, the seven driven gears are all meshedly connected with the internal gear.

[0011] Furthermore, a limiting groove is provided on the inner wall of the ear bin, and seven pairs of slide grooves are equidistantly provided on the inner wall of the ear bin. Slide bars are slidably connected in the seven pairs of slide grooves, and the slide bars are fixedly connected to the transmission rack, and a fan-shaped plate is fixedly connected to the inner wall of the slide bar.

[0012] Furthermore, a power shaft is rotatably connected to the middle of the limiting groove, the driving gear is fixedly sleeved on the outer wall of the power shaft, and a first friction roller is fixedly sleeved on the inner outer wall of the power shaft.

[0013] Furthermore, a card slot is opened in the outer ends of the two sleeve ear bins, a positioning ring is arranged in the middle of the card slot, and a filter net is fixedly installed on the inner wall of the positioning ring.

The fan-shaped plates can lock the cavity between the earmuff and the ear to prevent the headphone from falling off the user's head due to tilting. The structure is simple and easy to use, which increases the user's comfort, prevents the earphone from being dropped, and prolongs the service life of the headphone.

[0018] 2. Compared with the prior art, the present invention provides a disassembly and replacement component. When dust and debris accumulate on the filter and need to be cleaned, the earphone user can manually rub the second friction roller to drive the rotating shaft to rotate, thereby rotating the pulley. Under the linkage sleeve action of the transmission belt, the linkage frame moves with the transmission belt, pulling the five pressure pieces to rotate synchronously along the reference axis, and the clamping block moves with the rotation of the pressure piece to press and release the positioning ring, which is convenient for installing and disassembling the filter. The sleeve of the pulley, the pressure piece and the transmission belt can be linked to control the clamping block to lock and release the positioning ring, thereby controlling the installation and disassembly of the filter, making the filter easy to disassemble and clean, preventing the adhesion and accumulation of dust and debris, ensuring the cleanliness of the filter, and making the output sound effect of the earphone good, while protecting the health of the ears.
