Detailed Implementation
[0019] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.
[0020] Example 1: See Figures 1 to 3 This embodiment is applied to a bone conduction headphone, which includes a curved headband 1, a bone conduction vibrator 3 disposed on one side of the headband 1, and a fixing member 2 disposed on the other side of the headband 1, wherein the headband 1 is made of a thin metal sheet.
[0021] The earphone clip in this embodiment is made of rubber and includes a first inner clip 101 and a first outer clip 102 integrally formed. The cross-section of the earphone clip is U-shaped. A gap a is provided between the first inner clip 101 and the first outer clip 102. When in use, the earphone clip is clamped on the headband 1 using the gap a, and the position and support bar are adjusted according to the head shape of the tester.
[0022] See Figure 3 and Figure 4 The earphone clip has an inlay groove 103, the shape of which corresponds to the shape of the earphone clip's cross-section. A first spring piece 107 is embedded in the inlay groove 103. The first spring piece 107 has a U-shaped cross-section, comprising two symmetrical straight portions and an arc portion. The straight portions are disposed within the inner or outer clamping body, and the arc portion is used to drive the two straight portions to move closer together, thereby driving the first inner clamping body 101 and the second outer clamping body 102 to clamp the headband 1.
[0023] See Figure 3The first inner clip 101 has a hook-shaped first hair-binding part 104 on the side facing the tester. This hook-shaped part is integrally formed with the first inner clip 101 or is a hook-shaped metal piece embedded in the first inner clip 101. The first hair-binding part 104 has an L-shaped cross-section, with its horizontal portion connected to the first inner clip 101 and its vertical portion opposite to the first inner clip 101. The vertical portion of the first hair-binding part 104 is inserted into the tester's hair, and the horizontal portion of the hair-binding part supports the hair.
[0024] See Figure 4 The first outer clamp 102 has a long, strip-shaped first support bar 105 on the side furthest from the test subject. The first support bar 105 can be bent and deformed to support the auricle of the test subject. The first support bar 105 includes a rubber support bar sleeve and a copper guide wire 106 passing through the support bar sleeve. The guide wire 106 is deformed and supported by plastic deformation. The end of the support bar sleeve can be connected to the first outer clamp 102, or the end of the support bar sleeve can be integrally formed and connected to the first outer clamp 102.
