AI Technical Summary
The existing microphones have a symmetrical sound guide cone structure. Although they can evenly disperse the sound, users want the sound to have a directional enhancement of power and clarity when singing.
A microphone with an asymmetrical sound-guiding structure is designed, and the asymmetric structure of the sound-guiding body is adopted. By adjusting the grip direction and angle, the audio conduction effect in a certain direction is selectively enhanced.
Through the asymmetrical structure of the sound conductor, the audio conduction effect in a certain direction can be selected to meet the user's need to enhance the directionality of sound when singing.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of microphones, in particular to a microphone with an asymmetric sound guide structure. Background Art
[0002] In the past, people did not have the conditions to sing karaoke by themselves. Usually, buying a set of karaoke equipment would not only be expensive, but also take up space. If they wanted to sing karaoke, they often had to go to KTV. Although portable karaoke equipment existed, they were scarce and the sound quality was usually unsatisfactory.
[0003] Current microphones have a symmetrical sound guide cone structure, which can evenly disperse the sound and improve the user's perception of the sound. However, when singing karaoke, users often want the sound to be more directional to enhance the power and clarity. For this reason, we propose a microphone with an asymmetrical sound guide structure. Utility Model Content
[0004] In order to solve the problem that the current microphone has a symmetrical sound guide cone structure, which can evenly disperse the sound and improve the user's perception of the sound, but when singing karaoke, the user often hopes that the sound has directionality to enhance the sense of power and clarity, the utility model provides the following technical solutions: a microphone with an asymmetrical sound guide structure, comprising an audio response part, a connecting part and a hand-held part, the audio response part is connected to the top of the hand-held part through the connecting part, a microphone core is arranged on the upper part of the inner cavity of the audio response part, the microphone core is used for audio collection, a loudspeaker with a sound outlet facing downward is arranged on the lower part of the inner cavity of the audio response part, the microphone core is electrically connected to the loudspeaker, a sound guide body is arranged on the top of the hand-held part, the sound guide body is below the sound outlet of the loudspeaker, the sound guide body has a top pointing to the loudspeaker, and the side surfaces of the sound guide body have different slopes in different directions.
[0005] Preferably, the sound guide body is a sound guide cone, the top is the apex of the sound guide cone, and the apex does not coincide with the center of the sound guide cone.
[0006] Preferably, the top of the sound guide body is a straight-line structure.
[0007] Compared with the prior art, the beneficial effects of the utility model are:
[0008] By adopting an asymmetric sound guide, the audio conduction effect in a certain direction can be selectively enhanced by adjusting the direction and angle of holding the microphone. BRIEF DESCRIPTION OF THE DRAWINGS
