Example one

Please refer to fig. 1 to 5, the utility model discloses a microphone stereo set integral type equipment that first embodiment provided, including casing 10 with battery 50 in the casing, equipment is still including locating mark core receiver 20, circuit control panel 30, preceding stage audio frequency processing, digital processor, power amplifier, two unit speaker 40 in the casing 10 and connect two the angle modulation ware of unit speaker, mark core receiver 20 locates the upper end of casing 10, two unit speaker 40 rotate connect in the both sides of casing 10, mark core receiver 20 preceding stage audio frequency processing, digital processor, power amplifier and two unit speaker 40 all with circuit control panel 30 connects.

Specifically, the sound voiceprint 200 when the user sings is picked up by the microphone receiver 20 and transmitted to the circuit control panel 30 through the wire 21, the circuit control panel 30 is processed by the internal preceding stage audio frequency and the digital processor, wherein the digital processor collects the sound signal of the wire 21 in a digital form, and then the sound signal is processed by conversion, filtering, estimation, enhancement, compression, identification and the like to obtain a signal form meeting the requirement, and then the signal form is transmitted to the power amplifier of the circuit control panel 30 to become the driving unit loudspeaker 40 to generate sound, which can be understood, in the embodiment of the utility model, two unit loudspeakers 40 are arranged to transmit the sound to two ears of the user, which can be understood, in other embodiments of the utility model, in order to reduce the production cost and meet the requirement of the client of each price level, only one unit loudspeaker can be arranged, therefore, the utility model discloses be not limited to single, two unit speaker 40, and unit speaker 40 left and right sides sound channel is through the constructional device who improves (add angle regulator), only need the inclination (symmetry and asymmetry as shown in figure 1) a-b of adjustment unit speaker 40, make unit speaker 40 produce vibrations and produce the sound wave conveying with casing 10, and unit speaker 40 is the relative sound wave direction towards user's ear that produces of splayed, simultaneously through digital processor, will mark 360 angle curve characteristics (figure 3) under core receiver 20 different frequencies, because the frequency that receives heart type influence is great carries out modeling after the digital conversion, the sample, compare, shift the looks, reverse phase is handled, self-excitation distortion has just been solved under the condition of not adjusting frequency, the problem of whistling, user experience has been improved.

Specifically, in the present embodiment, the two-unit speakers 40 may be symmetrically disposed or asymmetrically disposed.

Specifically, the angle adjuster may be a rotating motor or the like connected to the unit speaker 40 to rotate the unit speaker 40 around the housing 10.

It should be noted that, limited by the fact that the mark core receiver is too close to the unit horn loudspeaker box (only 5CM), according to the principle of sound transmission, the directivity of the unit horn will present the distribution as shown in (fig. 2), and will directly radiate to the mark core receiver for pickup (influenced by the characteristics of the microphone receiver, refer to the heart type of fig. 3), causing the on-line repeated amplification and positive feedback resonance, and generating the distortion phenomena such as self-excitation, howling, and mark flying, causing the user experience to be very bad, therefore, in the embodiment of the present invention, the sound voiceprint can be pre-processed by changing the waveform of the sound voiceprint, modulating or delaying the phase of the sound voiceprint, or enhancing one or more of the geminal wave components of the sound voiceprint, and the sound voiceprint is collected in a digital form, so as to obtain a sound signal; and carrying out transformation, filtering, estimation, enhancement, compression and identification processing on the sound signal to obtain the modified sound signal.

Specifically, curve characteristics of a receiver of the microphone and sound integrated equipment within a range of 360 degrees under different frequencies can be obtained; and then obtaining the frequency with a larger difference value with the preset curve characteristic in the curve characteristic, carrying out digital conversion, modeling, sampling, comparing, phase shifting and phase inversion processing to obtain the angle required to be adjusted. In the implementation process, the selection of the heart-shaped and super-heart-shaped structures is favorable for solving the interference generated by the microphone and receiver directions at 90-270 degrees and the lower unit loudspeaker, which is illustrated by taking the heart-shaped as a case, the distance between the microphone and sound integrated device and the loudspeaker box is about 5CM in the near-field pickup, for example, in a heart-shaped 360-degree curve shown in (fig. 3), we find that the sound wave interference between 90-270 degrees is strong, and count out the frequencies with strong interference (for example, 1K and 5K, which will affect the microphone and sound integrated device receiver analog signal to form positive feedback with the unit loudspeaker to cause self-excited distortion), and amplify the sound obtained after the heart-shaped microphones are converted into digital signals, and then sample the frequency (for example, 1K) signals with strong interference and perform digital sampling, modeling, comparison and phase shifting, The sound wave played back is picked up by the microphone and receiver again, so that local offset of phase is formed, positive feedback self-excited howling distortion is not formed, and different frequencies are corrected in different phases, so that the phenomena of large volume, near field and no distortion can be solved.
