DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Combination Figures 1 to 4 A microphone convenient for voice control is shown, comprising a base 1, a support rod 2 is arranged above the base 1, a microphone 3 is arranged on the top of the support rod 2, the microphone 3 comprises a first hemispherical cover 31, a second hemispherical cover 32 is arranged on the other side of the first hemispherical cover 31, a connecting ring 33 is arranged between the first hemispherical cover 31 and the second hemispherical cover 32, and a sound collection mechanism 4 is arranged inside the first hemispherical cover 31 and the second hemispherical cover 32.

[0023] Among them, the sound collection mechanism 4 includes a mounting block 41, a plate-shaped sound receiver 42 is embedded on one side of the mounting block 41 and fixed by a snap, and a sound collecting tube 43 is embedded on the other side of the mounting block 41. The sound collecting tube 43 is connected to the mounting block 41 by screws. The sound collecting tube 43 can converge the sound, and the sound in the tube is louder and the collection effect is better.

[0024] A small microphone 44 is provided inside the sound collecting cylinder 43 and fixedly connected thereto. The small microphone 44 collects the sound inside the sound collecting cylinder 43 and converts it into an electrical signal.

[0025] The first hemispherical cover 31 is provided with a plurality of hollow rings 34 , which are connected by connecting ribs. After passing through the first hemispherical cover 31 , the sound is transmitted to the plate-shaped sound receiver 42 for rough sound source collection.

[0026] The first hemispherical cover 31 is located on one side of the plate-shaped sound receiver 42 and the sound collecting tube 43. The second hemispherical cover 32 is provided with a plurality of arc-shaped sound collecting holes 35. A circular through hole 36 is provided in the middle of the plurality of arc-shaped sound collecting holes 35. The circular through hole 36 faces the small sound receiver 44. After passing through the arc-shaped sound collecting holes 35 and the circular through hole 36, the sound is transmitted to the sound collecting tube 43 for sound source collection again.

[0027] The connecting ring 33 is connected to the first hemispherical cover 31 and the second hemispherical cover 32 by screws, and the mounting block 41 is fixed to the connecting ring 33 by buckles. The connecting ring 33 blocks the internal space of the microphone 3 to avoid generating a large echo, and facilitates the fixing of the overall structure of the microphone 3.

[0028] A threaded sleeve 45 is fixedly provided at the bottom of the mounting block 41 , and the threaded sleeve 45 is connected to the support rod 2 through threads.

[0029] Working principle: When the utility model is in use, when collecting sound, part of the sound passes through the first hemispherical cover 31 and then enters the plate-shaped sound receiver 42 for coarse sound source collection, and part of the sound passes through the arc-shaped sound receiving hole 35 and the circular through hole 36 and then enters the sound collecting tube 43 for further sound source collection. The sound is focused in the sound collecting tube 43, and the small sound receiver 44 collects the sound in the sound collecting tube 43 and converts it into an electrical signal. The sound in the tube is louder and the collection effect is better. The external host combines the sounds collected by the plate-shaped sound receiver 42 and the small sound receiver 44 to output the most accurate sound.
