[0027] See also Figure 1 The present invention provides a Bluetooth headset, including a headset body, wherein the handle section 10 of the headset body is split into two halves to form a middle shell 20 and a side shell 30, and a headset mainboard 40 is arranged in the middle shell 20. Figure 2 The inner wall of the side shell 30 is attached with a Bluetooth antenna 50 and a touch panel 60. The Bluetooth antenna 50 and the touch panel 60 are spaced and coupled with each other. Figure 1 The earphone motherboard 40 is provided with a plurality of connecting springs 70 on the side of the side shell 30. The Bluetooth antenna 50 and the touch panel 60 are electrically connected to the earphone motherboard 40 via the connecting springs 70. In the present invention, the Bluetooth antenna 50 and the touch panel 60 can be fabricated on the inner wall of the side shell 30 in the form of an LDS antenna. Specifically, a copper layer is first plated on the entire inner wall of the side shell 30, and then the shape of the Bluetooth antenna 50 and the touch panel 60 is formed on the inner wall of the side shell 30 through a laser forming process. The earphone motherboard 40 is provided with an antenna drive circuit and a touch control circuit. The touch panel 60 is electrically connected to the touch control circuit via the connecting springs 70, and the Bluetooth antenna 50 is electrically connected to the antenna drive circuit via the connecting springs 70. The utility model utilizes the inner wall of the side shell of the headphone stem to set the antenna and the touch panel, which reduces the space occupied by the antenna in the interior of the headphone stem. By coupling the touch panel with the antenna, the touch panel can also have a certain antenna function, thereby ensuring the strength of the headphone Bluetooth signal.

[0028] See also Figure 2In an optional embodiment of the present invention, the Bluetooth antenna 50 includes an H-shaped antenna body 80 and an oblique upper branch 90 connected to the outer side of the vertical arm of the H-shaped antenna body 80. The H-shaped antenna body 80 is specifically composed of a vertical arm and an inverted L-shaped arm, and the oblique upper branch 90 is connected to the side of the vertical arm away from the inverted L-shaped arm; the touch panel 60 includes a square touch panel body 100 and a coupling branch 110 forming an inverted L-shaped connection with the square touch panel 100. In the illustration of the present invention, the touch panel 60 can be abstractly understood as a kitchen knife shape; a Z-shaped gap 120 is formed between the Bluetooth antenna 50 and the touch panel 60 for coupling. The manner in which the Bluetooth antenna 50 and the touch panel 60 form a Z gap can be simply understood as the kitchen knife-shaped touch panel 60 being inverted and spaced apart and placed on the vertical arm step of the H-shaped antenna body 80. In an optional embodiment of the present invention, the Z-shaped spacing 120 is spaced 0.5 mm to 1 mm apart to better ensure coupling between the Bluetooth antenna 50 and the touch panel 60. The coupled Bluetooth antenna design of the present invention can cover the frequency band of 2400 MHz to 2500 MHz, with an antenna efficiency greater than 30% and an antenna standing wave ratio less than 3.

[0029] See also Figure 2 In an optional embodiment of the present invention, the leg of the vertical arm of the H-shaped antenna body 80 is a feeding leg 130, and the leg of the folded arm (i.e., the inverted L arm) of the H-shaped antenna body 80 is a grounding leg 140, see Figure 1 , several of the connecting springs 70 include a first connecting spring 150 for connecting to the feeding leg 130 and a second connecting spring 160 for connecting to the grounding leg 140. Of course, several of the connecting springs 70 also include a third connecting spring 170 for connecting to the square touch body 100 of the touch sheet 60.

[0030] See also Figure 3In an optional embodiment of the present invention, the first connecting spring 150, the second connecting spring 160, and the third connecting spring 170 each include a base plate 180 for connecting to the earphone motherboard 40, a resilient contact 190 disposed at the trailing edge of the base plate 180, and edge guards 200 disposed on the edges of the base plate 180 on both sides of the resilient contact 190 to limit the upward and downward elastic movement of the resilient contact 190. The resilient contact 190 includes an inverted L-shaped resilient support member 210 for connecting to the trailing edge of the base plate 180 and an inverted V-shaped contact member 220 connected to the floating end of the inverted L-shaped resilient support member 210. The connecting spring structure of the present invention has sufficient rebound contact margin and is also limited by the edge guard 200 to prevent deformation during long-term use. The Bluetooth antenna 50 and the touch panel 60 are electrically connected via the connecting spring structure of this embodiment, which can improve the reliability of the electrical connection and the service life of the connecting springs.

[0031] See also Figure 1 In an optional embodiment of the present invention, the bottom side of the handle of the earphone motherboard 40 is provided with a first charging contact pin 230 and a second charging contact pin 240 extending out of the middle shell 20 and in an eight-shaped shape. The first charging contact pin 230 and the second charging contact pin 240 are respectively connected to the positive and negative poles of the charging circuit on the earphone motherboard 40, and the Bluetooth headset can be prevented from being charged in the matching earphone compartment.

[0032] See also Figure 4 In an optional embodiment of the present invention, the top end of the handle section is connected to a sound cavity 250, and the shape of the sound cavity 250 can be abstractly understood as a bowl shape. The sound cavity 250 contains a speaker 260 and a battery assembly 270, and the speaker 260 and the battery assembly 270 are both connected to the earphone motherboard 40 (i.e., electrically connected).

[0033] See also Figure 4 In an optional embodiment of the present invention, an earplug cover 280 is provided on the opening of the sound cavity 250 (i.e., the bowl side), and a bowl-shaped ear cap 290 is provided on the sound outlet of the earplug cover 280. The bowl-shaped ear cap 290 is made of silicone and is detachable. The earphones of the present invention provide bowl-shaped ear caps 290 of various specifications and sizes so that users can choose the appropriate one for replacement. The earplug cover 280 is provided with air holes 300, which can balance the air pressure inside the earphone. When the earphone vibrates, the internal air pressure will change. The function of the air holes is to form an air flow channel inside the earphone to release the air pressure generated by the vibration, allowing the earphone to sound better, thereby bringing better sound quality.

[0034] In summary, the present invention provides a Bluetooth headset, comprising a headset body, wherein the stem section of the headset body is split in half to form a middle shell and a side shell, wherein a headset mainboard is disposed within the middle shell, and a Bluetooth antenna and a touch panel are attached to the inner wall of the side shell, wherein the Bluetooth antenna and the touch panel are spaced apart and coupled to each other, and a plurality of connecting springs are provided on the side of the headset mainboard facing the side shell, wherein the Bluetooth antenna and the touch panel are electrically connected to the headset mainboard via the connecting springs.
