[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] Please refer to Figure 1 , a conference room sound reinforcement management method provided by an embodiment of the present invention is applied to a conference host of a conference room sound reinforcement management system, the conference room sound reinforcement management system comprising: a conference host, an audio processing module and at least one extension module; the conference host is respectively connected to the audio processing module and the extension module in communication; one of the extension modules is arranged in a conference room;

[0039] The method comprises steps S101-S102:

[0040] Step S101: when receiving a first digital audio signal uploaded by any first extension module, sending the first digital audio signal to an audio processing module, so that the audio processing module performs data processing on the first digital audio signal to generate a second digital audio signal, and returns the second digital audio signal to the conference host;

[0041] Furthermore, each of the extension modules is respectively connected to at least one pickup module and at least one power amplifier; and each of the power amplifiers is respectively connected to at least one sound box.

[0042] Furthermore, after the first extension module receives the initial digital audio signal uploaded by the sound pickup module, the first digital audio signal is generated by adding a source IP address to the initial digital audio signal; the source IP address is the IP address of the first extension module;

[0043] When any one of the sound pickup modules connected to the first expansion module receives the sound information, the initial digital audio signal is converted and generated.

[0044] Further, sending the first digital audio signal to the audio processing module so that the audio processing module performs data processing on the first digital audio signal to generate a second digital audio signal, and returning the second digital audio signal to the conference host is specifically:

[0045] Sending the first digital audio signal to an audio processing module, so that the audio processing module optimizes the first digital audio signal using at least one audio algorithm to generate a second digital audio signal, and returns the second digital audio signal to the conference host;

[0046] The optimization processing includes: one or more of automatic gain, automatic mixing, feedback suppression, noise elimination, echo elimination, equalization processing, compression processing and limiting processing.

[0047] Step S102: When a second digital audio signal returned by the audio processing module is received, the second digital audio signal is sent to all extension modules, so that the second extension module performs a sound amplification and playback operation on the second digital audio signal according to the source IP address of the second digital audio signal; the IP address of the second extension module is the same as the source IP address.

[0048] Further, the sending of the second digital audio signal to all extension modules so that the second extension modules perform a sound amplification and playback operation on the second digital audio signal according to the source IP address of the second digital audio signal is specifically as follows:

[0049] The second digital audio signal is sent to all expansion modules so that the expansion modules can identify whether their own IP addresses are the same as the source IP address of the second digital audio signal. If so, the second digital audio signal is amplified by the connected first power amplifier and played through the speakers connected to the first power amplifier.

[0050] Further, when receiving the second digital audio signal returned by the audio processing module, the method further includes:

[0051] When a request is received to perform a sound amplification and playback operation on the third extension module for the first digital audio signal uploaded by the first extension module, the second digital audio signal is copied to generate a third digital audio signal; and the IP address of the third extension module is added to the third digital audio signal as the source IP address of the third digital audio signal, so that the third extension module performs a sound amplification and playback operation on the third digital audio signal according to the source IP address of the third digital audio signal.

[0052] In this embodiment, the second extension module can accurately identify and receive the second audio signal according to the IP address of the second audio signal. The IP address is selective, and the extension host with a different IP address will not receive it. For example, after the conference host receives the returned second digital audio signal, it only needs to send a second digital audio signal with an IP address, and the second extension module with the same IP address will accurately receive it for sound amplification and playback operations; if the second digital audio signal wants to be played on two extension hosts, the conference host only needs to copy the second digital audio signal and add the IP address of the third extension module after receiving the returned second digital audio signal, so that the second and third extension modules can simultaneously receive the same audio signal for sound amplification and playback operations.

[0053] Furthermore, the conference room sound reinforcement management system further comprises a conference management platform; the conference management platform is communicatively connected with the conference host;

[0054] The conference management platform is used to control the switches of each system module; the conference management platform is also used to set the audio algorithm of the audio processing module; the conference management platform is also used to set the IP address of each expansion module; the conference management platform is also used to adjust the operating parameters of the conference host, each pickup module and each power amplifier.

[0055] In order to better illustrate this embodiment, a preferred implementation scheme is provided. Please refer to Figure 2 , is a preferred conference room sound reinforcement management system, comprising: a conference host, an audio processing module and a plurality of extension modules; the conference host is respectively connected to the audio processing module and the extension module in communication; one extension module is set in a conference room, extension module 1 is deployed in conference room 1, extension module 2 is deployed in conference room 2, and so on. Each extension module is directly connected to a pickup module and a power amplifier; each power amplifier is respectively connected to two speakers. The pickup modules in each conference room are connected in series to the extension module.

[0056] In this embodiment, the conference management platform is generally installed on a computer, mobile phone or other device, and is connected to the conference host through a network, so as to remotely control the switches of the conference host, audio processing module, expansion module, pickup module and power amplifier; and adjust the parameters of the conference host, audio processing module, expansion module, pickup module and power amplifier;

[0057] Exemplarily, the conference management platform may set an audio algorithm for the audio processing module, set an optimized processing operation for the audio processing module and the audio algorithm selected therefor.

[0058] In this embodiment, the conference management platform can set the IP address of each extension module;

[0059] As one of the embodiments, each conference room is used separately, and the conference management platform sets a respective IP address for the extension module of each conference room to distinguish different conference rooms.

[0060] When conference participants use the sound pickup module to collect sound in their respective conference rooms, digital audio signals are generated and uploaded to the extension modules of their respective conference rooms. Each extension module adds its own IP address to the generated digital audio signal. The extension modules of each conference room upload the digital audio signals with added IP addresses to the conference host. The conference host sends the digital audio signals of each IP address to the audio processing module for optimization processing, generates optimized digital audio signals, and returns the optimized digital audio signals to the conference host.

[0061] The optimized digital audio signal still carries the IP address information. The conference host sends the optimized digital audio signal to all expansion modules. Each expansion module identifies the IP address of the received digital audio signal, determines the digital audio signal belonging to its own IP address, discards the digital audio signal that does not belong to its own IP address, amplifies the digital audio signal belonging to its own IP address through the connected first power amplifier, and plays it through the speakers connected to the first power amplifier.

[0062] The present invention achieves the purpose of distinguishing the source of a digital audio signal by adding an extension module IP address to the digital audio signal, uniformly processing the digital audio signal with an audio processing module, and distributing the digital audio signal to a corresponding conference room for playback using the IP address of the digital audio signal.

[0063] As another implementation scheme, when Conference Room 1 and Conference Room 2 need to be connected for use, the conference management platform sets the IP addresses of Conference Room 1 and Conference Room 2 to the same IP address. The digital audio signals collected by the sound pickup modules in Conference Room 1 and Conference Room 2 can be distributed to Conference Room 1 and Conference Room 2 for simultaneous audio playback after being processed by the audio processing module.

[0064] Implementing the embodiments of the present invention has the following effects:

[0065] The present invention realizes the management, control and audio processing of the sound reinforcement equipment of multiple conference rooms through a conference host, an audio processing module and a conference management platform; it is mainly aimed at solving the scenario where there are multiple conference rooms on one floor or one building, and can effectively reduce the equipment usage of the conference host and the audio processing module, thereby improving the management efficiency; in addition, the sound reinforcement equipment switches and parameter adjustments of multiple conference rooms are controlled by a conference management platform, which facilitates the unified management of multiple conference rooms by managers and improves the management efficiency.
