[0041] Please combine Figures 1 to 4The headset 1 provided in the first embodiment of the present invention comprises a middle piece 10, a head bow 11 fixedly connected to one end of the middle piece 10, and an earphone body 12 rotatably connected to the other end of the middle piece 10; telescopic parts 110 are respectively arranged on opposite sides of the head bow 11 close to the earphone body 12; a connecting part 111 is arranged in the middle part of the head bow 11, and opposite sides of the connecting part 111 are connected to the telescopic part 110; the telescopic part 110 comprises a shell 1100 and an internal accommodating space 1101, and opposite sides of the connecting part 111 are respectively fixed with an elastic sheet 113 and extend into the accommodating space 1101, and the telescopic part 110 can slide freely relative to the elastic sheet 113 in the extending direction of the head bow 11 toward the earphone body 12; the inner wall of the shell 1100 is provided with a fixing plate 1 102, the fixed plate 1102 abuts against the spring piece 113; a limit plate 1103 is respectively provided on the opposite sides of the fixed plate 1102 and defines two sliding grooves 1104 together with the fixed plate 1102; a first baffle 1130 is respectively provided on the opposite sides of the spring piece 113, and when the telescopic part 110 is telescoped along the sliding groove 1104, the first baffle 1130 abuts against the limit plate 1103; by arranging the first baffle 1130 and the limit plate 1103 on the opposite sides of the sliding telescopic part 110, the first baffle 1130 abuts against the limit plate 1103 at any time during the telescopic process of the telescopic part 110, so that during the telescopic process, the telescopic part 110 will not have unnecessary left and right shaking relative to the spring piece 113, thereby improving the telescopic stability of the head bow 11 and extending the service life.

[0042] Furthermore, please combine Figure 2 and Figure 4 A bow-shaped piece 112 is arranged inside the head bow 11, and the bow-shaped piece 112 supports the head bow 11; by arranging the bow-shaped piece 112 inside the head bow 11, the bow-shaped piece 112 can support the head bow 11, thereby improving the durability of the headphone 1.

[0043] It is understandable that since the main body of the head bow 11 is generally made of plastic material, the longer the head bow 11 is used, the more likely it is to break. Therefore, a bow piece 112 can be clamped inside the head bow 11, so that both ends of the bow piece 112 can extend to the position connected to the middle piece 10, thereby providing support for the head bow 11 in more areas, avoiding the situation where the head bow 11 breaks as the headset 1 is used for a longer time, thereby improving the durability of the headset 1. In this embodiment, preferably, the bow piece 112 can be a metal bow piece, which is stronger and more durable, has better stability, is not easy to wear, and has a longer service life.

[0044] Furthermore, the connecting portion 111 is provided with a second baffle 1110 in a direction perpendicular to the spring sheet 113 at the fixed portion of the connecting portion 111, and the second baffle 1110 and the outer shell 1100 respectively abut against two sides of the bow-shaped piece 112; this arrangement can ensure that when the telescopic portion 110 slides, the outer shell 1100 and the second baffle 1110 can limit the bow-shaped piece 112, thereby improving the stability of the head bow 11 during telescopic operation and extending its service life.

[0045] Furthermore, please combine Figure 2 and Figure 4 The two ends of the bow piece 112 are set as bent ends 1120. When the telescopic part 110 is stretched to reach the maximum length, the second baffle 1110 abuts against the bent end 1120, thereby preventing the telescopic part 110 from being pulled off, improving the stability of the head bow 11 during extension and retraction, and extending the service life.

[0046] Furthermore, a protrusion 1131 is provided at one end of the spring piece 113 away from the connecting portion 111, and a plurality of grooves 1105 are provided at intervals on the fixing plate 1102. Whenever the telescopic portion 110 is extended or retracted by a certain distance, the protrusion 1131 enters the groove 1105 accordingly; the protrusion 1131 cooperates with the groove 1105, and whenever the telescopic portion 110 is extended or retracted by a certain distance, the groove 1105 on the fixing plate 1102 can limit the telescopic portion 110, so that it will not be extended or retracted at will, thereby ensuring stability and comfort when worn.

[0047] Furthermore, the surface of the groove 1105 and the interval between adjacent grooves 1105 are arc-shaped, and the surface of the protrusion 1131 is an arc-shaped surface; the surfaces of the groove 1105 and the protrusion 1131 are both arc-shaped, which reduces the friction when the spring piece 113 is extended and retracted, making the spring piece 113 smoother when extended and retracted, thereby improving the feel of use.

[0048] Furthermore, the spring piece 113 is made of an elastic material; the spring piece 113 made of the elastic material can allow the spring piece 113 to smoothly escape from the groove 1105 when the telescopic portion 110 slides.

[0049] For further information, please refer to Figure 5 and Figure 6 The earphone body 12 includes an earmuff 120 and a connecting piece 121, one end of the connecting piece 121 is rotatably connected to the middle piece 10, and the other end is fixedly connected to the earmuff 120; the rotatable connection between the connecting piece 121 and the middle piece 10 allows the earmuff 120 to be rotated and folded when not in use, thereby reducing the volume of the headphone 1 and facilitating storage.

[0050] Furthermore, please combine Figure 5 and Figure 6The earmuff 120 includes a sound outlet 1200, a circular protrusion 1201 on one side of the earmuff 120 opposite to the sound outlet 1200, and a connecting member 121 includes a connecting rod 1213 and an arc-shaped arm 1210 connected to one end of the connecting rod 1213; the arc-shaped arm 1210 is arranged around the circular protrusion 1201, and the arc-shaped arm 1210 is divided into a first part 1211 and a second part 1212 by the connecting rod 1213, and the length of the first part 1211 is less than the length of the second part 1212; the central axis L (such as Figure 6 L) and the direction M of the head arch 11 (as shown in Figure 6 M) forms an inclination angle α (as shown in Figure 6 α shown in the figure), the inclination angle α ranges from 20° to 30°; preferably, the inclination angle α is 25°; the arc arm 1210 is divided into two parts, a long part and a short part, so that the central axis of the earphone body 12 forms an inclination angle with the head bow 11, which can allow the user to place the head bow 11 at the back of the head when wearing it, reduce the pressure of the head bow 11 when wearing it, and improve wearing comfort.
