Description

Technical Field

[0001] The utility model relates to the technical field of head-worn earphones, in particular to an adjusting mechanism for a head-worn earphone. Background Technique

[0002] A head-worn earphone refers to an earphone that is worn on the head rather than inserted into the ear canal. It has a good sound field, good comfort, can avoid scratching the ear canal, and has very good sound quality performance in terms of high, middle, and low frequencies. Even when playing symphonies, it has a good listening experience.

[0003] During the use of the existing head-worn earphones, the adjusting mechanism can adjust the length. However, during the use process, due to the different head shapes of each person, the adjusting mechanism is prone to continuous stretching, and it cannot be positioned after stretching. The continuous stretching process affects the fitting degree of the ears, thereby reducing the noise reduction efficiency and not meeting the use requirements. For this reason, the utility model provides an adjusting mechanism for a head-worn earphone. Content of the Utility Model

[0010] Further, the number of the moving grooves is two groups and they are symmetrically distributed. The moving grooves are arc-shaped structures. The limiting grooves are communicated with the moving grooves. The number of the limiting grooves is equal to the number of the moving grooves, and the length of the moving grooves is greater than the length of the limiting grooves.

[0011] Further, the limiting block is fixedly connected to the adjusting rod. The limiting block is adapted to the limiting groove. The number of the positioning grooves is several groups and they are distributed in an array. The thickness of the positioning groove is less than that of the adjusting rod.

[0012] Further, the number of the receiving grooves is two groups and they are symmetrically distributed. The support seat is fixedly connected to the handle. The number of both of them is two groups and they are symmetrically distributed. The side cross-section of the handle is an "L" shaped structure. The support seat is adapted to the receiving groove.

[0013] Further, both ends of the connecting spring are respectively connected to the support seat and the receiving groove. The positioning block is fixedly connected to the support seat. One side edge of the positioning block is an arc structure. The positioning block is adapted to the positioning groove.

[0014] Compared with the above background technology, the headphone adjusting mechanism provided by the present application includes a support rod, an adjusting rod and a positioning component. In order to prevent the adjusting rod from being continuously stretched during use, the positioning block is inserted into the corresponding positioning groove, so that the adjusting rod is positioned inside the moving groove. The structure is simple and the operation is convenient.

[0015] The utility model provides a headphone adjusting mechanism. Compared with the prior art, it has the following beneficial effects:

[0016] A headphone adjusting mechanism. By arranging a positioning component between the support rod and the adjusting rod, when the adjusting rod is pulled out, the user holds the handle, so that the handle drives the support seat and the positioning block to be pulled upward, the connecting spring is stretched, the positioning block is disengaged from the inside of the positioning groove, and the adjusting rod is elongated along the inside of the moving groove, while driving the limiting block to move along the inside of the limiting groove until it is elongated to a suitable position. Then release the handle. Under the elastic potential energy of the connecting spring, the positioning block is inserted into the corresponding positioning groove to position the adjusting rod, ensuring that the adjusting rod will not be continuously stretched during the use of the headphone and maintaining the fitting degree between the headphone body and the ear.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution for a headphone adjustment mechanism of a headset: a headphone adjustment mechanism of a headset includes a support rod 1, and further includes: an adjusting rod 2, the number of the adjusting rods 2 is two groups, and a positioning component 3 is arranged between the adjusting rod 2 and the support rod 1; the positioning component 3 includes a moving groove 31, a limiting groove 32 opened inside the moving groove 31, a limiting block 33 connected to the end of the adjusting rod 2, a positioning groove 34 opened outside the adjusting rod 2, a receiving groove 35 opened at the upper end of the support rod 1, a support seat 36 and a connecting spring 37 arranged inside the receiving groove 35, a handle 38 connected to the upper end of the support seat 36, and a positioning block 39 connected to the bottom of the support seat 36.

[0024] Among them, the number of the headphone bodies 4 is two groups and they are symmetrically distributed. The headphone bodies 4 are connected to the ends of the adjusting rods 2. A control circuit board, a battery and a speaker are arranged inside the headphone bodies 4, which is beneficial to the connection between the headphone bodies 4 and the adjusting rods 2 and is convenient for the user to wear and use the headphones.

[0025] In addition, the number of movable grooves 31 is two groups and they are symmetrically distributed, the movable grooves 31 are arc-shaped structures, the limiting grooves 32 are connected to the movable grooves 31, the number of limiting grooves 32 is equal to the number of movable grooves 31, and the length of the movable grooves 31 is greater than the length of the limiting grooves 32, the limiting block 33 and the adjusting rod 2 are fixedly connected, the limiting block 33 and the limiting groove 32 are adapted to each other, the number of positioning grooves 34 is several groups and they are distributed in an array, the thickness of the positioning grooves 34 is less than the thickness of the adjusting rod 2, the number of storage grooves 35 is two groups and they are symmetrically distributed, and the support seat 36 and the handle 38 are fixedly connected. The handle 38 is connected, and the number of both is two groups and they are symmetrically distributed. The side profile of the handle 38 is an "L"-shaped structure. The support seat 36 and the storage groove 35 are adapted to each other. The two ends of the connecting spring 37 are respectively connected to the support seat 36 and the storage groove 35. The positioning block 39 and the support seat 36 are fixedly connected. One side edge of the positioning block 39 is an arc structure. The positioning block 39 and the positioning groove 34 are adapted to each other, which is conducive to positioning the adjustment rod 2 along the inside of the support rod 1, so that the adjustment rod 2 will not be continuously stretched during wearing, thereby maintaining the stability of the adjustment rod 2.
