Embodiment 1

[0035] Such as Figure 1-Figure 3 As shown, the embodiment of the present invention provides a microphone mounting structure, including a handle portion 1, an internal circuit board 2, a microphone 3, and a sound guide 5. The handle 1 is cylindrical and is used by the operator to hold it. It has a first cavity with a bottom at one end. The bottom is provided with a through microphone hole 11 that communicates with the first cavity. The external sound passes through the microphone. The hole 11 enters the first cavity of the handle 1. The internal circuit board 2 is arranged in the first cavity of the handle 1 and extends along the length of the handle 1. The end of the internal circuit board 2 close to the microphone appearance hole 11 deviates from the axis of the microphone appearance hole 11; both sides of the internal circuit board 2 All are equipped with electronic devices. The microphone 3 is fixed to one end of the lower surface 23 of the internal circuit board 2 by ref...

Embodiment 2

[0039] Such as Figure 4 As shown, the embodiment of the present invention provides a microphone mounting structure, including a handle portion 1, an internal circuit board 2, a microphone 3, and a sound guide 5. The structure of the handle 1 is the same as that of the first embodiment, with a first cavity and a microphone appearance hole 11 communicating with the first cavity; the installation method of the internal circuit board 2 is also the same as that of the first embodiment. The difference between this embodiment and the first embodiment lies in: the position of the microphone 3, the structure of the internal circuit board 2, and the structure and installation manner of the sound guide 5 are different.

[0040] In this embodiment, the microphone 3 is fixed to one end of the upper surface 22 of the internal circuit board 2 by reflow soldering, and the sound receiving hole 31 of the microphone 3 is located on the non-welded surface of the microphone 3. Since the sound receiv...

Embodiment 3

[0044] This embodiment provides a wireless headset, including the microphone installation structure described in any one of the first embodiment and the second embodiment. In other words, the microphone 3 of this embodiment can be fixed on the lower surface 23 of the internal circuit board 2 and located outside the sound guide 5, wherein the sound receiving hole 31 is located on the side of the microphone 3 that contacts the internal circuit board 2 and is connected to the internal circuit The sound guide holes 21 on the board 2 are aligned. At this time, one end of the sound guide channel 4 is connected to the sound guide hole 21, and the other end is connected to the microphone appearance hole 11, so as to realize the sound receiving function of the microphone 3. Alternatively, the microphone 3 of this embodiment may also be located on the upper surface 22 of the internal circuit board 2 and inside the sound guide sleeve 5. The sound receiving hole 31 is located on the non-wel...

Abstract

The invention belongs to the technical field of earphone manufacturing, and particularly relates to a microphone mounting structure and a wireless earphone, and the microphone mounting structure comprises a handle part, an internal circuit board, a microphone and a sound guide sleeve. The handle part is provided with a first cavity with a bottom surface, and the bottom surface is provided with a through microphone appearance hole; the internal circuit board is located in the cavity of the handle part, and one end, close to the microphone appearance hole, of the internal circuit board deviatesfrom the axis of the microphone appearance hole; the microphone is fixed at one end, close to the surface of the microphone appearance hole, of the internal circuit board and is provided with a soundreceiving hole; the sound guide sleeve is arranged in the first cavity and is provided with a second cavity, the second cavity, the internal circuit and the bottom surface of the handle part form a sound guide channel, one end of the sound guide channel is connected with the sound receiving hole, and the other end of the sound guide channel is communicated with the microphone appearance hole, so that the sound receiving hole is aligned to the microphone appearance hole, and the sound receiving function of the microphone is realized; the microphone mounting structure of the wireless earphone isconvenient to assemble, simple in structure and low in production cost.

Description

Technical field [0001] The present invention relates to the technical field of headset manufacturing, in particular to a microphone installation structure and a wireless headset. Background technique [0002] For many wireless headset products on the market, the microphone’s appearance hole is located at the bottom of the headset handle for beautiful appearance. Because the bottom space of the handle is small and limited by the layout of the internal circuit board, the vertical installation of the microphone and its To align with the appearance holes, it is usually necessary to set a small circuit board at the bottom of the handle, solder the microphone to the small circuit board, and then connect the small circuit board to the main circuit board through a lead or soft board to ensure the circuit connection between the microphone and the main circuit board , To achieve the microphone's radio function. There are many fixing methods and production process steps of this kind of mic...
