Embodiment 1

[0030] like figure 1 , image 3 , Figure 5 As shown, the splicing control system of a sounding device in the present invention includes at least one modulator 1 for receiving the sound source signal 6 and generating a high-frequency signal as a carrier wave mixed with the received sound source signal 6 to form a modulated signal, and several modulators for A signal amplifier 3 for amplifying and outputting the modulated signal, several sounding devices 5 for receiving the modulated signal amplified by a signal amplifier 3 and making sound, the modulator 1 is connected to the signal amplifier 3 , and the signal amplifier 3 is connected to the sounding device 5 . The sound source signal 6 is a sound signal of a microphone or a CD or DVD or MP3.

[0031] It also includes a micro-processing unit 2 for receiving the modulated signal sent by the modulator 1 and performing phase processing on the received modulated signal. The micro-processing unit is connected to the modulator 1 ...

Embodiment 2

[0046] The difference between this embodiment and embodiment 1 is:

[0047] like figure 2 and Figure 4 As shown, it also includes a communication module 7 for connecting to an intelligent terminal 8 , and the communication module 7 is connected to the modulator 1 . The smart terminal 8 and the communication module 7 are used to replace the sound source signal 6, and the sound source can be replaced remotely through the smart terminal 8 to adjust the volume level.

Abstract

The invention discloses a sound production device splicing control system and method. The system comprises a modulator which is used for receiving sound source signals and taking high-frequency signals generated by the modulator as carriers to be mixed with the received sound source signals to form modulation signals, signal amplifiers which are used for amplifying and outputting the modulation signals, and sound production devices which are used for receiving the modulation signals amplified by one signal amplifier and producing sound. The modulator is connected with the signal amplifier, and the signal amplifier is connected with a sound production device. According to the invention, the sound pressure can be effectively improved, so that a user can hear a better sound effect, more flexible sound field combination can be realized, the application requirements are met, and the cost is reduced, and the freight, the installation and the maintenance are convenient due to the splicing mode of a plurality of sound production devices.

Description

technical field [0001] The invention relates to the technical field of sound generation, in particular to a splicing control system and method for sound generation devices. Background technique [0002] In the process of sound propagation, within the coverage of a sound reinforcement direction generating device, high sound pressure is provided, and high-definition and high-natural sound propagation can be realized. The improvement of the sound pressure of the acoustic parametric array is a difficult point in the scientific research of the parametric array in various countries. The current research and development are all by increasing the sound pressure of a single generating device. Moreover, how to increase the sound pressure when a single sound generating device is difficult to upgrade in the short term, and the single block sound generating device with large sound pressure has the problems of high production cost, difficult transportation, and high maintenance cost. How ...
