Description

Technical Field

[0001] The utility model relates to the technical field of TWS earphones, in particular to a TWS earphone with a compact structure. Background Art

[0002] TWS earphones are the abbreviation of true wireless Bluetooth earphones, which consist of two independent earplugs and a rechargeable storage box. The biggest advantage of TWS earphones is that there will be no problem of earphone wire entanglement when wearing them. This experience is subversive. Although some people are worried that TWS earphones are easy to fall off, most of the TWS earphones on the market are designed in accordance with human ear engineering and generally will not fall off during daily use. When the TWS earphones on the market are in use, the internal earphone slot is tightly fitted with the earphone body without any gap, which makes it inconvenient to use, especially when there is a small amount of sweat on the hands. For this reason, we propose a compact TWS earphone. Utility Model Content

[0006] Preferably, a charging port is installed near the middle of the bottom of the first machine box.

[0007] Preferably, the top of the first machine box is convex near the middle, and the bottom of the second machine box is concave inwardly.

[0008] Preferably, a groove matching the earphone body is formed at the bottom of the second box.

[0009] Preferably, the side walls on both sides of the limiting rod are fixedly connected to limiting blocks near the bottom end, and the inner wall of the limiting hole is provided with a limiting groove matching the limiting block.

[0010] Preferably, the inner wall of the limiting hole is polished.

[0011] Preferably, a slot is provided at the bottom of the first machine box near the right side, a fixed shaft is fixedly connected to the inner wall of the slot, a hanging rope is sleeved on the fixed shaft, and a hanging ring is fixedly connected to the bottom end of the hanging rope.

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

[0013] In the present technical solution, through the mutual cooperation between the spring, the limit rod, the limit block and the annular block, it can be achieved that when the second machine box is opened and the annular block is not subject to the limiting pressure of the second machine box, the spring stretches and drives the annular block to move upward a short distance, thereby driving the earphone body to move upward to make it easier to use; through the mutual cooperation between the hanging rope and the hanging ring, the earphone as a whole can be mounted, making it more convenient to carry.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a compact TWS headset, comprising a first machine box 1, the top of the first machine box 1 is movably connected to a second machine box 5 through a hinge near the rear, the top of the first machine box 1 is provided with two earphone slots 3 arranged in the left and right directions, the earphone slot 3 is provided with an earphone body 4, the bottom of the second machine box 5 is provided with a groove matching the earphone body 4, the earphone slot 3 is provided with an annular groove near the top, an annular block 8 is provided in the annular groove, a plurality of uniformly distributed limiting rods 10 are fixedly connected to the bottom of the annular block 8, a limiting hole matching the annular block 8 is provided at the bottom of the inner cavity of the annular groove, a spring 9 is fixedly connected between the bottom end of the limiting rod 10 and the bottom of the inner cavity of the limiting hole, the left and right side walls of the limiting rod 10 are fixedly connected to the limiting blocks 11 near the bottom, and the inner wall of the limiting hole is provided with a limiting block matching the limiting block 11 The first machine box 1 is equipped with a limiting groove, and the inner wall of the limiting hole is polished. A charging port 2 is installed near the middle of the bottom of the first machine box 1, and the top of the first machine box 1 is convex near the middle. The bottom of the second machine box 5 is concave inwardly. A slot is opened near the right side of the bottom of the first machine box 1, and a fixed shaft 6 is fixedly connected to the inner wall of the slot. A hanging rope 7 is sleeved on the fixed shaft 6, and a hanging ring is fixedly connected to the bottom end of the hanging rope 7. Through the mutual cooperation among the spring 9, the limiting rod 10, the limiting block 11 and the annular block 8, it can be realized that when the second machine box 5 is opened and the annular block 8 is not subject to the limiting pressure of the second machine box 5, the spring 9 stretches and drives the annular block 8 to move upward a short distance, thereby driving the earphone body 4 to move upward to make it easier to take; through the mutual cooperation between the hanging rope 7 and the hanging ring, the earphone can be mounted as a whole, so that it is more convenient to carry.

[0021] Working principle: When in use, insert the earphone body 4 into the earphone slot 3, close the second machine box 5 to drive the earphone body 4 to move downward a short distance, so that the earphone body 4 can fit tightly with the groove and the earphone slot 3. At this time, the spring 9 is in a compressed state. When taking it out, open the second machine box 5. At this time, the earphone body 4 is not subject to the limiting pressure of the second machine box 5. The spring 9 stretches and drives the annular block 8 to move upward a short distance through the limiting rod 10. The earphone body 4 is moved upward for a distance so that there is enough gap between it and the earphone slot 3 for easy access. The whole can be mounted anywhere through the hanging rope 7 and the hanging ring for easy carrying.
