Bone conduction earphones use bone conduction technology to receive words, close to the bone, and the sound waves are directly transmitted to the auditory nerve through the bone. Therefore, both ears can be opened without hurting the tympanic membrane, and therefore it is loved by consumers. However, when assembling the battery or the control circuit board in the existing bone conduction earphones, it is necessary to assemble the battery or the control circuit board into a shell integrally formed with the earhook, and further use a silicone strip to stick to the exposed part of the battery or the control circuit board for packaging. At this time, the volume of the housing needs to be set to accommodate most of the batteries or control circuits, which makes the positioning, assembly and wiring of the batteries or control circuits more complicated, which is not conducive to assembly and wiring.

可选的是，天线主体145a包括平行部145a1与弯折部145a2，在垂直于电路板141的方向上观察，平行部145a1的宽度大于弯折部145a2的宽度，平行部145a1一端连接接地部145b以及馈电部145c，另一端连接弯折部145a2，平行部145a1与弯折部145a2在连接处呈阶梯状设置，弯折部145a2从连接处向电路板141的一侧弯折。Optionally, the antenna main body 145a includes a parallel portion 145a1 and a bent portion 145a2, viewed in a direction perpendicular to the circuit board 141, the width of the parallel portion 145a1 is greater than the width of the bent portion 145a2, and one end of the parallel portion 145a1 is connected to the ground portion 145b And the power feeding part 145c, the other end is connected to the bent part 145a2, the parallel part 145a1 and the bent part 145a2 are arranged in a stepped shape at the joint, and the bent part 145a2 is bent toward one side of the circuit board 141 from the joint.
可选的是，控制电路组件14进一步包括设置于电路板141上的接地部件146，其中天线主体145a向电路板141的远离接地部件146的一侧弯折延伸。在本实施例中，接地部件146为USB接口和/或电路上的开关142，或者其他接地部件146。一般，接地部件146例如USB接口，都会对天线145造成一定的干扰，在本实施例中，天线主体145a向电路板141的远离接地部件146的一侧弯折延伸，能够在有限空间内改善接地部件146对天线145信号的干扰，保证信号质量。在本实施例中，USB接口可用于在骨传导耳机与外界设备例如移动终端传输数据，也可用于为电池组件13充电。Optionally, the control circuit assembly 14 further includes a grounding component 146 disposed on the circuit board 141 , wherein the antenna main body 145 a bends and extends toward a side of the circuit board 141 away from the grounding component 146 . In this embodiment, the grounding component 146 is a USB interface and/or a switch 142 on the circuit, or other grounding components 146 . Generally, the grounding component 146, such as the USB interface, will cause certain interference to the antenna 145. In this embodiment, the antenna body 145a is bent and extended toward the side of the circuit board 141 away from the grounding component 146, which can improve grounding in a limited space. The interference of the component 146 to the signal of the antenna 145 ensures the signal quality. In this embodiment, the USB interface can be used to transmit data between the bone conduction earphone and an external device such as a mobile terminal, and can also be used to charge the battery assembly 13 .
可选的是，天线主体145a的宽度沿天线主体145a的延伸方向逐渐变小。例如具体地，平行部145a1的宽度从一端到另一端宽度不变，弯折部145a2的宽度逐渐沿延伸方向逐渐变小。当然在其他实施例中，平行部145a1的宽度从一端到另一端可以逐渐变小，但平行部145a1另一端的宽度仍大于弯折部145a2的宽度。Optionally, the width of the antenna main body 145a becomes gradually smaller along the extending direction of the antenna main body 145a. For example, specifically, the width of the parallel portion 145a1 is constant from one end to the other end, and the width of the bent portion 145a2 gradually decreases along the extending direction. Of course, in other embodiments, the width of the parallel portion 145a1 may gradually decrease from one end to the other end, but the width of the other end of the parallel portion 145a1 is still greater than the width of the bent portion 145a2.
可选的是，天线主体145a的弯折角度沿天线主体145a的延伸方向逐渐变大。例如弯折角度逐渐变大，一般是为了远离接地部件146例如USB等，从而保证天线145的辐射效率。可选的是，在弯折部145a2远离平行部145a1的一端具有弯折脚145a3，此处的弯折角度最大，一方面为了满足天线145尺寸的需要，另一方面是为了提升辐射效率。Optionally, the bending angle of the antenna main body 145a becomes gradually larger along the extending direction of the antenna main body 145a. For example, the bending angle becomes gradually larger, generally to keep away from the grounding component 146 such as USB, so as to ensure the radiation efficiency of the antenna 145 . Optionally, there is a bent foot 145a3 at the end of the bent part 145a2 away from the parallel part 145a1, where the bent angle is the largest, on the one hand to meet the size requirements of the antenna 145, and on the other hand to improve radiation efficiency.
