In addition, the anechoic chamber has good sound insulation and absorption effects, and sound energy emitted from the loudspeaker assembly 4 can be effectively isolated, absorbed and attenuated by the anechoic chamber, so that the sound of the loudspeaker assembly 4 is relatively effectively blocked and weakened to be transmitted to the microphone to form self-excitation, and the howling of the howling-preventing K-song microphone is effectively prevented.

In one embodiment, as shown in fig. 3 and 4, the sound-deadening assembly includes a first sound-deadening layer 311 mounted (adhesively or otherwise) on the inside of the first mesh 31, and a second sound-deadening layer 21 mounted (adhesively or otherwise) on the bracket 2 away from the lower space 34; the first muffling layer 311 and the second muffling layer 21 enclose the anechoic chamber. It is understood that the first sound-deadening layer 311 and the second sound-deadening layer 21 each include, but are not limited to, a sound-deadening sponge or the like, and the first sound-deadening layer 311 and the second sound-deadening layer 21 make the upper space 33 the anechoic chamber in which the microphone 1 is located. In this embodiment, the noise reduction assembly has the advantages of simple structure, low manufacturing cost and convenience in installation.

It should be noted that the first sound-deadening layer 311 and the second sound-deadening layer 21 enclose only an ideal space similar to an anechoic chamber, which has a technical effect similar to that of an anechoic chamber, but is not an anechoic chamber in a straight sense.

Specifically, the sound entering the anechoic chamber is effectively absorbed when passing through the first sound-deadening layer 311 and/or the second sound-deadening layer 21, so that reflected sound waves, harmonics, noise waves, and the like are not generated in the anechoic chamber.

In an embodiment, as shown in fig. 1 to 4, the first mesh cover 31 is provided with a forward hole set 312 and a backward hole set 313; the front hole group 312 is used for transmitting sound to the front side of the diaphragm of the microphone 1, and the back hole group 313 is used for transmitting sound to the back side of the diaphragm of the microphone 1. It is understood that the forward hole set 312 is located right above the first mesh enclosure 31, the backward hole set 313 is located below the first mesh enclosure 31, the microphone 1 divides the upper space 33 into a first space and a second space, the forward hole set 312 communicates with the first space, and the backward hole set 313 communicates with the second space. It should be noted that two diaphragms are arranged on the microphone 1 to generate sound, the forward hole group 312 is arranged opposite to the diaphragm above, the backward hole group 313 is arranged opposite to the diaphragm below, the diaphragm above is used for receiving sound, the diaphragm below is used for generating reverse wave suppression sound, when the upper and lower diaphragms receive the same sound wave at the same time, the two diaphragms vibrate in opposite directions, the phases of the generated sound waves are completely opposite, the angles differ by 180 degrees, and after being superimposed, the sound finally received by the microphone 1 and transmitted to the system is the sound received by the forward hole group 312 minus the sound received by the backward hole group 313, so that the microphone has strong angle sound reception suppression.

Specifically, when the voice is transmitted from the front angle of the forward hole group 312 on the top of the first mesh enclosure 31, the voice sound pressure received by the forward hole group 312 is strongest because the voice has a strong directivity, and the voice sound pressure received by the backward hole group 313 is weaker, so that the reverse suppression effect is very weak, and at this time, the microphone 1 can obtain stronger voice to transmit to the system, and thus obtain better voice to be output from the speaker assembly 4. When the external sound enters from the side angle of the first mesh enclosure 31, the sound received by the forward hole group 312 and the backward hole group 313 are superimposed to each other, so that the suppression effect is very strong, and the sound around the peripheral side of the first mesh enclosure 31 is effectively suppressed. When the external sound enters from the side of the first mesh enclosure 31, the sound pressure intensity of the sound received by the forward hole group 312 and the back hole group 313 is not very different, and the suppression effect is very strong after the two groups are mutually overlapped due to the completely opposite phases, so that the sound around the peripheral side of the first mesh enclosure 31 is effectively suppressed. When the sound emitted by the speaker assembly 4 is received by the forward hole group 312 and transmitted to the diaphragm above the microphone 1, and part of the sound is received by the backward hole group 313 and transmitted to the diaphragm below the microphone 1, so that the forward sound and the backward sound of the diaphragm of the microphone 1 have opposite phases, namely the sound waves have a phase difference of 180 degrees in forward and backward directions, and the sound waves with opposite phases acting on the diaphragm of the microphone 1 are superposed and offset with each other, so that the sound output by the speaker assembly 4 is received and suppressed by the microphone 1, and the sound output by the speaker assembly 4 is effectively isolated from a sound receiving loop of the microphone 1, thereby further suppressing the squeal of the anti-squeal K microphone.
