Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and more specifically, to a retractable headphone. Background Technology

[0002] Over-ear headphones are headphones worn on the head, not inserted into the ear canal. They offer good soundstage, comfort, and prevent ear canal abrasion. Their sound quality across high, mid, and low frequencies is excellent, providing a good listening experience even with symphonic music. The mid-range volume is particularly rich. While existing over-ear headphones use elastic clips to automatically engage with different slots to adjust the length of the headband, this adjustment mechanism suffers from poor stability. The telescopic arms are prone to shifting under stress, making it difficult to maintain the overall shape after adjustment. This reduces the reliability of the headphones and affects the user experience. Therefore, this invention designs a telescopic over-ear headphone to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a retractable headphone to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A retractable headset includes a headband, two telescopic arms, and an earphone head. The earphone head is fixedly mounted at the bottom end of the telescopic arms. Limiting slots are provided on both ends of the headband. The telescopic arms slide through the bottom of the headband and extend into the limiting slots. T-shaped studs are threaded to both sides of the headband. Several locking screw grooves are spaced apart on the sides of the telescopic arms. The T-shaped studs are adapted to the locking screw grooves. An anti-slip strip is fixedly mounted at the upper end of the telescopic arms. The anti-slip strip is slidably connected to the limiting slot.

[0006] As a preferred embodiment of this utility model, a knob block is fixedly connected to the side of the T-shaped stud, and the knob block has rounded corners on its sides.

[0007] As a preferred embodiment of this utility model, the headband has lateral grooves at the positions corresponding to the T-shaped studs on both sides, and the knob block is located in the lateral grooves.

[0008] As a preferred embodiment of this utility model, the end face of the headband is flush with the end face of the anti-slip strip.

[0009] As a preferred embodiment of this utility model, a soft padding layer is fixedly installed on the inner side of the headband, and the soft padding layer is a component made of rubber.

[0010] As a preferred embodiment of this utility model, the top of the headband is fixedly connected with a hanging ear, and the end face of the hanging ear is provided with a circular hanging hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a knob block to rotate the T-shaped stud in the forward direction, disengaging it from the locking screw groove. This allows the telescopic arm to slide along the bottom of the headband. The anti-disengagement strip slides into the limiting slot, effectively preventing the telescopic arm from detaching from the headband. Once the desired extension / retraction is achieved, the knob block is used to rotate the T-shaped stud in the reverse direction. The T-shaped stud then connects to the corresponding locking screw groove on the telescopic arm, locking and positioning the adjusted telescopic arm. This ensures the stability of the telescopic structure, prevents the telescopic arm from easily shifting under force, maintains the overall shape after extension / retraction adjustment, improves the reliability of the headphones, and guarantees a superior user experience.

[0019] 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.

[0020] like Figures 1 to 5 As shown, this utility model provides a telescopic headphone, including a headband 1, two telescopic arms 2, and an earphone head 3. The earphone head 3 is fixedly installed at the bottom end of the telescopic arms 2. Limiting slots 101 are opened on both ends of the headband 1. The telescopic arms 2 slide through the bottom of the headband 1 and extend into the limiting slots 101. T-shaped studs 4 are threaded to both sides of the headband 1. Several locking screw grooves 201 are spaced apart on the side of the telescopic arms 2. The T-shaped studs 4 are adapted to the locking screw grooves 201. The T-shaped studs 4 can be threaded to the corresponding locking screw grooves 201 on the telescopic arms 2, so that the telescopic arms 2 are locked and positioned after telescopic adjustment. An anti-disengagement strip 5 is fixedly installed at the upper end of the telescopic arms 2. The anti-disengagement strip 5 is slidably connected to the limiting slots 101 to effectively prevent the telescopic arms 2 from detaching from the headband 1.

[0021] Among them, such as Figure 3 and Figure 5 As shown, a knob block 6 is fixedly connected to the side of the T-shaped stud 4. The knob block 6 has rounded corners 601 on its side, which facilitates the rotation of the T-shaped stud 4.

[0022] Among them, such as Figure 3 As shown, the headband 1 has lateral grooves 102 at the positions corresponding to the T-shaped studs 4 on both sides. The knob block 6 is located in the lateral grooves 102 and can be set to be hidden.

[0023] Among them, such as Figure 1 As shown, the end face of the headband 1 is flush with the end face of the anti-slip strip 5, which helps to ensure the overall appearance of the headphones.

[0024] Among them, such as Figure 2 As shown, a soft padding layer 7 is fixedly installed on the inner side of the headband 1. The soft padding layer 7 is a component made of rubber, which makes the headphones comfortable to wear.

[0025] Among them, such as Figure 2 As shown, the top of the headband 1 is fixedly connected to an ear hook 8, and the end face of the ear hook 8 is provided with a circular hanging hole 801, which facilitates the hanging and placement of the headphones.

[0026] The working principle of this utility model:

[0027] During use, if telescopic adjustment is required, use the knob block 6 to rotate the T-shaped stud 4 clockwise, causing the T-shaped stud 4 to disengage from the locking screw groove 201. The telescopic arm 2 then slides along the bottom of the headband 1. The anti-disengagement strip 5 slides with the limiting slide 101, effectively preventing the telescopic arm 2 from disengaging from the headband 1. Once the desired telescopic shape is achieved, use the knob block 6 to rotate the T-shaped stud 4 counterclockwise. The T-shaped stud 4 is threaded into the corresponding locking screw groove 201 on the telescopic arm 2, thus locking and positioning the telescopic arm 2 after adjustment. This ensures the stability of the telescopic structure, prevents the telescopic arm 2 from easily shifting under force, and facilitates the stable maintenance of the overall shape after telescopic adjustment.
