fig. 3 is an exploded perspective view of the present invention;

fig. 4 is an exploded view of the combination of the lens leg tone mesh and the acoustic hole of the present invention;

fig. 5 is a cross-sectional view of the sound receiving hole of the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the following specific embodiments and accompanying drawings.

The utility model relates to an audio frequency glasses product, it is shown in figure 1 to figure 5 to see, the utility model discloses a: the glasses leg 1, the glasses leg 1 comprises a shell, and the shell comprises a cover 13 and a base 14 which are mutually matched. The cover 13 and the base 14 have a mounting cavity 10 therein for accommodating the earphone circuit 2.

The earphone circuit 2 comprises a circuit board 20, and the earphone circuit 2 is powered by a battery 6 arranged in the mounting cavity 10. And a sound receiving microphone 3 is arranged on the earphone circuit 2.

The front end of the glasses leg 1 is provided with a connecting end 15 connected with the glasses frame, the rear end of the glasses leg 1 is provided with a charging electrode 16, and the battery 6 is charged through the charging electrode 16. The entire temple 1 has an inner side 101 that fits the user, an outer side 102 opposite the inner side 101, and an upper side 103 and a lower side 104 that connect the inner side 101 and the outer side 102. Since the inner side surface 101 is attached to the side of the head of the user when the user wears the glasses, it is inconvenient to provide the sound-receiving hole. The outer side 102 is far from the sound source, which is also not favorable for sound reception. Therefore, the sound receiving hole 11 of the present invention is formed on the upper surface 103 or the lower surface 104. In order to improve the sound receiving effect, the present invention is provided with sound receiving holes 11 on the upper side 103 and the lower side 104, and the positions of these two sound receiving holes 11 are staggered with each other to obtain sound sources from different positions.

The sound receiving microphone 3 is arranged in the cavity 10 and close to the sound receiving hole 11. The radio microphone 3 of the present invention is not directly disposed inside the acoustic hole 11, but communicates the radio microphone 3 with the acoustic hole 11 through a bending passage 12. This has the advantage that the air flow entering through the acoustic opening 11 does not reach the acoustic microphone 3 immediately, but needs to pass through the bent passage 12, which reduces the air flow velocity and thus the wind noise.

Specifically, the bending passage 12 includes: a first passage 121 communicating with the sound reception microphone 3 and a second passage 122 communicating with the sound reception hole 11, and the first passage 121 and the second passage 122 orthogonally communicate.

As shown in fig. 5, this is a sectional view of the lower side 104 of the temple 1 with the sound-receiving hole 11. When the circuit board 20 of the earphone circuit 2 is installed, the circuit board 20 is supported by the column 141, the sound receiving microphone 3 is arranged on the inner side surface of the circuit board 20, the foam 5 is arranged on the outer side surface of the circuit board 20, the foam 5 is positioned at the outlet of one end of the inner side of the bending channel 12, and a through hole 200 is formed in the position, corresponding to the sound receiving microphone 3, of the circuit board 20. The opening mode of the bending channel 12 is as follows: the bending channel 12 is formed in the main body 141 and opens a first through hole 121 inwardly from the top surface of the pillar 141. The second channel 122 is opened from the outside to the inside along the lower side 104 (or the upper side 103), and penetrates through the middle section of the first channel 121. Therefore, the external air flow firstly enters the second channel 122, and when the air flow enters the first channel 121 from the second channel 122, the air flow directly impacts the bent inner wall of the channel, so that the wind speed is greatly reduced, and the wind noise is effectively overcome. In addition, in order to further reduce the wind speed, the aperture of the first passage 121 is larger than that of the second passage 122.

The sound hole net 4 is arranged on the sound collecting hole 11, the sound hole net 4 is made of metal materials, dense meshes are formed in the sound hole net 4, and the sound hole net 4 can achieve the effects of noise reduction and wind noise resistance structurally.

As shown in fig. 4 and 5, a flange 41 is formed on the outer edge of the tonehole mesh 4, and an annular groove 110 matched with the flange 41 is formed in the tonehole 11. A boss 111 is formed in the central area of the annular groove 110 of the acoustic opening 11, and an outlet at one end outside the bending channel 12 is opened on the boss 111. When the device is installed, the flange 41 of the sound hole net 4 is clamped and embedded at the annular groove 110, so that the sound hole net 4 is used for forming blocking isolation for a section of outlet outside the bending channel 12.

The above is the cross-sectional view of the sound-absorbing hole 11 formed in the lower side 104 of the temple 1, and the structure of the sound-absorbing hole 11 formed in the upper side 103 is the same, and the two are only different in position, and will not be described in detail here.

Of course, the above description is only for the specific embodiment of the present invention and is not intended to limit the scope of the present invention, and all equivalent changes or modifications made by the structure, characteristics and principles according to the claims of the present invention should be included in the claims of the present invention.
