Embodiment 1

[0030] Embodiment 1, this embodiment proposes an antenna device, such as figure 2 , image 3 As shown, it includes a circuit board 11, and also includes a radiator 12. An antenna 13 is arranged on the circuit board 11. The radiator 12 is located on one side of the circuit board 11. The radiator 12 is made of a conductive material, and the radiator 12 has a first connection. At point 121, there is a second connection point 111 on the circuit board 11, the first connection point 121 is connected to the second connection point 111 through a wire 14, and the second connection point 111 is connected to the ground point on the circuit board 11 through a ground wire. 14 Connect the radiator 12 to the ground point of the circuit board 11 to realize the connection between the radiator 12 and the ground point on the circuit board 11 . In this solution, by increasing the radiator 12, the radiator 12 is located on one side of the circuit board 11, and there is a certain distance between...

Embodiment 2

[0047] Embodiment 2, this embodiment proposes a bluetooth headset, such as Image 6 As shown, it includes a housing 21, a loudspeaker assembly (not shown in the figure because of the angle) arranged in the housing 21, and also includes the antenna device described in Embodiment 1. The antenna device is arranged in the housing 21 and radiates The body 12 is located on the side of the circuit board close to the ear when worn. Such as Figure 7 As shown, the radiator 12 is located near the ear, and the radiation pattern of the antenna is changed so that more energy is radiated toward free space, thereby reducing the impact on the human body and the deterioration of the performance of the antenna on the head of the human body.

[0048] For other structures of the antenna device, please refer to the description in Embodiment 1, which will not be repeated here. It should be noted that in this embodiment, the radiator 12 can be fixed on the shell of the earphone, on the speaker shel...

Abstract

The invention discloses an antenna device and a bluetooth earphone. The antenna device includes a circuit board and a radiator. An antenna is arranged on the circuit board. The radiator is located on one side of the circuit board. The radiator is made of conductive material. A connection point, the circuit board has a second connection point, the first connection point is connected to the second connection point through a wire, and the second connection point is connected to the ground point on the circuit board through a ground wire. The antenna device of the present invention arranges a radiator on one side of the circuit board, and a coupling current is generated on the radiator, which can change the edge radiation field of the signal, and the coupling current communicates with the circuit board to form a cycle of coupling current, which can change the radiation direction of the antenna , so that more energy radiates toward free space, thereby reducing the radiation impact of electromagnetic wave signals on the human body. At the same time, changing the radiation direction of the antenna so that more energy radiates toward free space can reduce the attenuation of the signal by the human body and improve the communication quality.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to an antenna device and a bluetooth earphone. Background technique [0002] Electronic devices with wireless communication functions are provided with antenna elements to send and receive signals. In recent years, wearable devices with wireless communication functions have become more and more widely used. Wearable devices include Bluetooth headsets, smart watches, and smart bracelets. Wearable devices are generally worn close to the body, and they are relatively close to the human body. Especially for Bluetooth headsets, the Bluetooth antenna configured has a radiation direction similar to that of a dipole (electric dipole). figure 1 As shown, they radiate to both sides respectively. When the user wears and uses it, part of the electromagnetic signal radiates to the free space outside the earphone main body 30, and the other part radiates to the head of ...
