[0002] Bluetooth headsets are popular among users due to their convenience and compactness, and their use is becoming increasingly widespread. However, using headsets for a long time can easily cause damage to the ears. You need to pay attention to the volume and usage time when using them. In addition, it is easy to lose hearing the sounds on the road when wearing headsets while walking or riding. For this reason, clip-on Bluetooth headsets came into being.

[0003] However, there are some problems with the existing technology: most of the existing Bluetooth headset antennas use wires to connect various components, and the earplugs of ear clip-on Bluetooth headsets are small and have little internal space. The wires take up too much internal space of the headset, which also makes the assembly of the Bluetooth headset antenna more complicated. Therefore, we propose an ear clip-on Bluetooth headset antenna based on laser engraving processing. Utility Model Content

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 6 As shown, an embodiment of the present invention provides an ear-clip type Bluetooth headset antenna based on laser engraving processing, including a circuit board 1, which is circular and made of plastic material. The main function of the circuit board 1 is to fix various parts.

[0024] A circuit assembly 2 is provided on the circuit board 1. The circuit assembly 2 includes a radiation element 201 and an electronic component 202. The radiation element 201 and the electronic component 202 are fixedly connected to the circuit board 1. A laser engraved circuit 203 is provided on the surface of the circuit board 1. The laser engraved circuit 203 is used to connect the radiation element 201 and the electronic component 202.

[0025] The radiating element 201 is the main part of the antenna, responsible for transmitting and receiving electromagnetic waves. The radiating element 201 can be linear (such as a dipole antenna) or planar (such as a patch antenna). The specific shape and size depend on the required operating frequency and the design requirements of the antenna. The electronic component 202 is used to process various signals. The radiating element 201 and the electronic component 202 are directly fixed on the circuit board 1 and then connected through the laser-engraved circuit 203, which greatly reduces the use of wires and reduces the demand for internal space in the headphones.

[0026] A mounting hole is provided on the circuit board 1, and a fixing rod 8 is movably connected in the mounting hole. A fixing component 3 is provided at one end of the fixing rod 8. The fixing component 3 is used to fix the circuit board 1. The fixing component 3 includes a clamping block 301. The upper end of the clamping block 301 is fixedly connected to a rotating shaft 302. A groove is provided on the side of the fixing rod 8. The clamping block 301 is rotatably connected in the groove through the rotating shaft 302. The clamping block 301 is triangular in shape. A first spring 303 is fixedly connected to one side of the clamping block 301. The first spring 303 is fixedly connected to the groove of the fixing rod 8. A limiting plate 6 is also fixedly connected to the middle of the fixing rod 8, and the circuit board 1 is located above the limiting plate 6.

[0027] After aligning the mounting holes on the circuit board 1 with the fixing rod 8, press the circuit board 1 downward, and the circuit board 1 will apply a thrust to the clamping block 301, causing the clamping block 301 to compress the first spring 303 and retract into the fixing rod 8. When the circuit board 1 moves to the limit plate 6, it can no longer move downward. At this time, the clamping block 301 is no longer subject to the thrust of the circuit board 1, and is thus moved outward by the rebound force of the first spring 303, thereby fixing the circuit board 1 on the fixing rod 8.

[0028] The other end of the fixed rod 8 is movably connected to the fixed plate 4, and a buffer assembly 5 is provided on the fixed plate 4. The buffer assembly 5 includes a buffer column 501, which is fixedly connected to the upper end of the fixed plate 4. The upper end of the buffer column 501 is open, and the inner wall of the buffer column 501 is fixedly connected to the second spring 502, and the second spring 502 is fixedly connected to the buffer block 503, and the buffer block 503 is fixedly connected to the fixed rod 8.

[0029] When the Bluetooth headset falls, the circuit board 1 will be subjected to the impact force, causing the circuit board 1 to move, thereby driving the fixing rod 8 to move, and the fixing rod 8 then drives the buffer block 503 to move. The buffer block 503 will compress the second spring 502, so that the second spring 502 will offset the impact force, thereby protecting the circuit board 1 from damage and extending the service life of the Bluetooth headset.

[0030] A wire hole 7 is provided in the middle of the fixing plate 4 and is used for connecting external circuits.

[0031] The working principle of this utility model is as follows:

[0032] The utility model reduces the space occupied by the circuit inside the Bluetooth headset by fixing the radiation element 201 and the electronic component 202 on the circuit board 1, and then setting a laser engraved circuit 203 on the circuit board 1 to connect the radiation element 201 and the electronic component 202. At the same time, a buffer component 5 is set on the support structure of the antenna. When the Bluetooth headset falls and is impacted, the second spring 502 can offset the impact force, thereby avoiding damage to the circuit board 1 caused by the impact force and extending the service life of the Bluetooth headset.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
