[0033] The strong sound dispersing device is a defensive security device, which can emit high-intensity sound waves to achieve the purpose of dispersing personnel, and is generally applied in public security scenes.
[0034] In the related art, the existing strong sound dispersing device is often independently deployed, and if a single point failure occurs, the application may not be achieved. Moreover, the actual use environment is relatively complex, such as different distances, different range target areas, and the use of the same strong sound dispersing device may be difficult to achieve good results, and the applicability is general.
[0035] Therefore, the application provides a multi-drive strong sound dispersing device and a strong sound dispersing array.
[0036] The application provides a multi-drive strong sound dispersing device.
[0037] The application provides a multi-drive strong sound dispersing device. Figure 1 The application provides a multi-drive strong sound dispersing device.
[0038] The application provides a multi-drive strong sound dispersing device.
[0039] The application provides a multi-drive strong sound dispersing device.
[0040] The application provides a multi-drive strong sound dispersing device.
[0041] In the embodiments of the present application, a multi-drive strong sound dispersion device is provided, which comprises a sound source input interface, an input selection module, an audio processing module, a cascade control module and a plurality of groups of drive output modules. The sound source input interface can be used to receive input audio signals, and the number thereof can be multiple. Each sound source input interface can receive different sound source input audio signals. For example, in some embodiments, the sound source types connected to the multi-drive strong sound dispersion device in the embodiments of the present application can include but are not limited to Bluetooth sound sources, MP3 sound sources, MIC sound sources, etc., and the present application does not make any limitation in this regard.
[0042] In the embodiments of the present application, the main function of the input selection module in the multi-drive strong sound dispersion device is to select one or more sound source signals from a plurality of sound source input interfaces for playing. The input selection module can be one or more switch selectors, which can switch different input signal sources according to the needs of users. For example, in some embodiments, the input selection module can use physical buttons, knobs or other toggle switches, etc. The electronic switch or relay inside the input selection module will route the selected audio signal to the output according to the selection operation, that is, connect the circuit between the selected sound source input interface and the audio processing module, so as to transmit the audio signal to the audio processing module.
[0043] The audio processing module is mainly responsible for processing the audio signal to improve the quality of the audio signal and improve the output effect. For example, common audio processing methods include amplification, filtering, equalization, compression, limiting, etc. In the embodiments of the present application, the audio processing module can use any product on the market, and the present application does not make any limitation on the processing effect thereof. The audio signal processed by the audio processing module can be transmitted to the cascade control module and each group of drive output modules. In the embodiments of the present application, the cascade control module can be used to realize the connection between different multi-drive strong sound dispersion devices. For example, the cascade control module of one multi-drive strong sound dispersion device can be connected to the sound source input interface of another multi-drive strong sound dispersion device, so that the joint output between different multi-drive strong sound dispersion devices can be realized. For example, please refer to Figure 2 , Figure 2 a circuit schematic diagram of a cascade control module provided in the embodiments of the present application is shown, Figure 2 In the embodiments of the present application, C15-1 and C16-1 can be connected to the audio processing module, and P4 can be used as a cascade port to connect the sound source input interface of another multi-drive strong sound dispersion device.
[0044] It should be noted that the operation of the cascade can be extended to a scenario of more than two multi-drive strong sound dispersion devices, thereby forming a strong sound dispersion array. In the strong sound dispersion array, multiple multi-drive strong sound dispersion devices can be used for outputting sound waves. Thus, for a relatively broad area, a better strong sound dispersion effect can be achieved based on the strong sound dispersion array. For a relatively small area, only one single multi-drive strong sound dispersion device can be used, thereby greatly improving the applicability of the multi-drive strong sound dispersion device.
[0045] As shown in Figure 1 In the embodiment of the present application, the drive output module of the multi-drive strong sound dispersion device can include multiple drive output modules, denoted as drive output module 1, drive output module 2,..., and drive output module N, where N is a positive integer, and the present application does not limit the specific number thereof. Please refer to Figure 3 , Figure 3 A multi-drive strong sound dispersion device including two drive output modules is shown, one drive output module is arranged on each of the left and right sides, that is, even if one drive output module fails, the other drive output module can also work to output sound waves, which can improve the operation stability and reliability of the multi-drive strong sound dispersion device.
[0046] For one drive output module, it can include a drive circuit and a transducer, wherein the input end of the drive circuit is connected to the audio processing module, the audio signal processed by the audio processing module can be output to the drive circuit, the output end of the drive circuit is connected to the transducer, and the transducer is a device capable of converting one form of energy into another form of energy. In the embodiment of the present application, the transducer can be a loudspeaker, which converts the audio signal into a high-decibel sound wave output. In the embodiment of the present application, the decibel of the sound wave signal output by the transducer can be greater than or equal to 130 decibels, for example, it can be 141 decibels, etc.
[0047] It can be understood that the multi-drive strong sound dispersion device provided in the embodiment of the present application includes a sound source input interface, an input selection module, an audio processing module, a cascade control module, and multiple groups of drive output modules; the sound source input interface is used to receive an input audio signal, the sound source input interface is connected to the input selection module, the input selection module is connected to the audio processing module, the audio processing module is connected to the cascade control module and each group of drive output modules; the drive output module includes a drive circuit and a transducer, the input end of the drive circuit is connected to the audio processing module, the output end of the drive circuit is connected to the transducer, and the transducer is used to output a sound wave signal. The strong sound dispersion device of the present application includes multiple groups of drive output modules, which can also achieve sound wave output in the case of single-point failure, and is provided with a cascade control module, which can conveniently achieve the cascade application of multiple multi-drive strong sound dispersion devices, thereby adapting to different use environments and needs, and having better applicability.
[0048] In some embodiments, the multi-drive strong sound dispersing device further comprises a power supply circuit.
[0049] Specifically, in the embodiments of the present application, a power supply circuit can be arranged in the multi-drive strong sound dispersing device, which can be externally connected to other power supplies to supply power to each module and component in the multi-drive strong sound dispersing device by voltage conversion. For example, the power supply circuit can include a DC-DC converter for converting input DC power into power of a required voltage level for use. The specific circuit structure of the present application is not limited.
[0050] In some embodiments, the audio processing module comprises a pre-stage processing unit; the pre-stage processing unit is connected to the drive circuit of each group of drive output modules.
[0051] In the embodiments of the present application, the audio processing module can include a pre-stage processing unit, which can be used to implement pre-stage processing of the audio signal, that is, to preliminarily adjust and optimize the original audio signal to ensure that the subsequent processing steps can be more effectively performed. The purpose of pre-stage processing is to improve the audio quality, reduce noise interference, and prepare the best signal state for recording or playing. For example, the pre-stage processing unit can implement functions such as gain adjustment, equalization, noise reduction, and clipping, and the present application is not limited in this regard. Please refer to Figure 4 , Figure 4 A circuit schematic diagram of a pre-stage processing unit provided in the embodiments of the present application is shown, which includes an NJM2761 chip. NJM2761 is a high-performance single-channel audio power amplifier chip that can provide high output power at low voltage and has low total harmonic distortion (THD) to ensure high-quality audio output. Of course, it can be understood that other types of chips can also be used in the pre-stage processing unit in the embodiments of the present application, and the present application is not limited in this regard.

In the embodiments of the present application, each multi-drive strong sound dispersing device is connected through a cascade control module, and the cascade control module of a previous multi-drive strong sound dispersing device is connected to the audio source input interface of a subsequent multi-drive strong sound dispersing device. In this way, only the first multi-drive strong sound dispersing device needs to receive audio signal input, which can be dispersed to each multi-drive strong sound dispersing device for sound wave signal output. In actual use, the user can flexibly adjust the number of multi-drive strong sound dispersing devices configured in the strong sound dispersing array according to the needs, so as to be suitable for different distances and different range target areas.
[0053] In some embodiments, the strong sound dispersion array can also be provided with a power adapter, which can power each multi-drive strong sound dispersion device, and the voltage level of the output is not limited, and can be flexibly determined according to actual needs.
