The adjustment base includes an adjustment cylinder 6 fixedly connected to the back of the voice acquisition unit and a circular adjustment plate 12 locked inside the adjustment cylinder 6. The adjustment plate 12 is fixedly connected to the clip via a connecting block 1201. A compression spring 8 is provided inside the adjustment cylinder 6 between the adjustment plate 12 and the voice acquisition unit. The compression spring 8 can press the adjustment plate 12 against the retaining ring 7 at the outer end of the adjustment cylinder 6, increasing the friction between the adjustment plate 12 and the inner wall of the retaining ring 7, and preventing relative movement with the user's movements in a free state.

[0031] The wearable voice acquisition device is clipped to the user's collar when worn. By adjusting the position of the adjustment seat, the sound acquisition port 2 is aligned with the user's mouth and its position is fixed, which facilitates the adjustment of the sound pickup distance and direction. This allows the device to pick up the user's voice in a directional manner based on the wearing position, effectively improving the completeness and clarity of the acquired voice.

[0032] As a further optimization, such as Figure 7 As shown, a compression plate 9 is disposed inside the adjusting cylinder 6 between the adjusting plate 12 and the compression spring 8. A guide mechanism is provided between the compression plate 9 and the adjusting cylinder 6, which allows the adjusting plate 12 to move only along the axial direction of the adjusting cylinder 6.

The clip is integrally formed and made of spring steel or elastic resin material. The inner side of the first clip 13 and the inner side of the straight section of the second clip 14 are provided with a rubber or silicone anti-slip layer.

[0037] As a further optimization, the inner side of the first clamping plate 13 and the inner side of the straight section of the second clamping plate 14 are provided with arc-shaped protrusions, and the arc-shaped protrusions on the first clamping plate 13 and the second clamping plate 14 are staggered to increase the clamping force and friction on the collar. As a further optimization, the free end of the first clamping plate 13 is tilted towards the voice collector for easier clamping onto the collar.
