Description

Technical Field

[0001] This invention belongs to the field of headphone technology, specifically relating to a headphone device with adjustable wearing clamping force. Background Technology

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Headphones are generally detachable from the media player, connected via a plug. The advantage is that they allow for private listening without disturbing others; they also isolate ambient noise, which is helpful for people using them in noisy environments such as recording studios, bars, while traveling, or exercising. Originally designed for telephones and radios, headphones are now widely used with mobile phones, portable music players, radios, portable game consoles, and digital audio players, thanks to the prevalence of portable electronic devices.

[0003] The existing technology has the following problems: most of the current headphone devices that can adjust the wearing clamping force have poor adaptability. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a headphone device with adjustable clamping force, characterized by high adaptability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a headphone device with adjustable clamping force, comprising a first steel wire rope, a first micro motor installed near the center of the first steel wire rope, a headband of the headphone located below the first micro motor, a second steel wire rope installed on the inner side of the headband of the headphone, both the first and second steel wire ropes being connected to the headband of the headphone via multiple loops, a second micro motor located near the center of the second steel wire rope, two headphone bodies installed below the headband of the headphone, the two headphone bodies being connected to the second steel wire rope via a first fixing point and a fourth fixing point respectively, and the two headphone bodies being connected to the first steel wire rope via a second fixing point and a third fixing point respectively.

[0006] Preferably, the first micro motor and the second micro motor have the same model.

[0007] Preferably, the headband of the headphones is directly fixed to the headphone body by welding.

[0008] Preferably, the number of the cable loops shall not be less than twelve.

[0009] Preferably, the headband of the headphones has an arched design.

[0010] Preferably, the total length of the second wire rope is less than the total length of the first wire rope.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This invention, by incorporating a first micro motor, a second micro motor, a first steel wire rope, a second steel wire rope, a headband for headphones, and a cable loop, allows different wearers to adjust the clamping force and sealing of the headphones according to their own needs, thereby improving the comfort experienced by the user and enhancing the adaptability of the headphones.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-3 The present invention provides the following technical solution: a headphone device with adjustable wearing clamping force, comprising a first steel wire rope 3, a first micro motor 1 installed near the center of the first steel wire rope 3, a headphone headband 10 disposed below the first micro motor 1, a second steel wire rope 4 installed on the inner side of the headphone headband 10, the first steel wire rope 3 and the second steel wire rope 4 being connected to the headphone headband 10 by multiple cable loops 11, a second micro motor 2 disposed near the center of the second steel wire rope 4, two headphone bodies 7 being installed below the headphone headband 10, the two headphone bodies 7 being connected to the second steel wire rope 4 by a first fixing point 5 and a fourth fixing point 9 respectively, and the two headphone bodies 7 being connected to the first steel wire rope 3 by a second fixing point 6 and a third fixing point 8 respectively.

[0019] To ensure the normal operation of the second micro motor 2, in this embodiment, preferably, the first micro motor 1 and the second micro motor 2 are of the same model.

[0020] To ensure the normal operation of the headband 10 of the headphones, in this embodiment, preferably, the headband 10 of the headphones is directly fixedly connected to the headphone body 7 by welding.

[0021] To ensure the normal operation of the cable loops 11, in this embodiment, preferably, the number of cable loops 11 shall not be less than twelve.

[0022] To ensure the normal operation of the headband 10 of the headphones, in this embodiment, the headband 10 of the headphones is preferably designed in an arch shape.

[0023] In order to ensure the normal operation of the second wire rope 4, in this embodiment, preferably, the total length of the second wire rope 4 is lower than the total length of the first wire rope 3.

[0024] The working principle and usage process of this invention are as follows: First, the user wears the headphones on their head. Then, by using buttons or an app, the user can operate the micro motor control chip inside the headphone body 7 to select whether the headphones need to retract or expand. When retraction is needed, the first micro motor 1 and the second micro motor 2 are activated simultaneously. One end of the first steel wire rope 3 is fixed at the second fixed point 6, and the other end is fixed at the third fixed point 8. The first steel wire rope 3 passes through the loop 11 and is wound around the shaft of the first micro motor 1. As the motor rotates, the first steel wire rope 3 gradually loosens. One end of the second steel wire rope 4 is fixed at the first fixed point 5, and the other end is fixed at the fourth fixed point 9. The second steel wire rope 4 passes through the loop 11 and is wound around the shaft of the second micro motor 2. As the motor rotates, the second steel wire rope 4 gradually tightens. This changes the clamping force and sealing of the headphones by adjusting the bending angle of the headband 10. When expansion is needed, the first micro motor 1 and the second micro motor 2 are activated in reverse. After adjustment, the headphones begin to work.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
