[0028] Working principle: the Bluetooth module in the control panel 4 is connected with an external audio device, the holding handle 5 is held by hand, and the first cover body 6 is spoken to, the sound first enters the first cover body 6 through the first through hole 7, and the sound receiving part 8 converts the vibration signal of the sound into an electric signal, the electric signal is transmitted to the sound emitting part 11, and the electric signal is amplified and then converted into a sound signal, and then the sound signal is released from the sound guide area 12 of the second cover body 14, when the three sound guide areas 12 are aligned with the three sound emitting parts 11, the three sound guide areas 12 uniformly conduct the sound, so that the sound is conducted in left, middle and right directions, the sound intensity of the three directions is the same, when the second cover body 14 is rotated, one of the sound guide areas 12 on the two sides is blocked by the mounting column 2, the sound transmission area of this position is reduced, the sound is transmitted from the sound guide area 12 with smaller area, the sound transmission area of the remaining two sound guide areas 12 does not change, but the direct transmission of part of the sound is hindered, so the sound intensity and sound effect can be changed, which can be adjusted according to the actual scene, when one of the sound guide areas 12 is blocked by the mounting column 2, for example, the sound guide areas 12 on the left and right sides are opposite to the two sound emitting parts 11, and the other sound guide area 12 is blocked by the mounting column 2, so that the sound emitted by the sound emitting part 11 in the middle can only be transmitted from the sound guide areas 12 on the left and right sides through the sound guide groove 25, so the sound intensity of the left and right sides can be enhanced, when one of the sound guide areas 12 on the left and right sides is blocked by the mounting column 2, the sound emitted by the sound emitting parts 11 on the left and right sides can only be transmitted from the sound guide area 12 in the middle position through the sound guide groove 25, so the sound intensity of one side on the left and right sides is weakened, and the sound intensity of the middle part is enhanced, so the adjustment of the sound transmission direction and the sound intensity of the wireless microphone can be realized.

[0029] It will be obvious to a person skilled in the art that the application is not limited to the details of the above-described exemplary embodiments, but that the application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. The embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.

[0030] Furthermore, it should be understood that although the description is made on the basis of the embodiments, not every embodiment contains only one independent technical solution, and the description is made in this way only for the sake of clarity, and a person skilled in the art should consider the description as a whole, and the technical solutions in each embodiment can also be combined appropriately to form other embodiments that can be understood by a person skilled in the art.
