Description

Technical Field

[0001] The present application relates to the technical field of audio equipment, and more specifically, to an audio adjustment method, device, equipment and storage medium for an IP broadcast speaker. Background Art

[0002] With the continuous development of IP broadcasting technology, people's demand for audio playback equipment is growing. As a common device in IP broadcasting systems, the functions of IP broadcasting speakers are constantly enriched as user needs increase. Nowadays, users require IP broadcasting speakers to support multiple audio source inputs, such as network audio sources, local line inputs, Bluetooth audio sources, wireless microphone audio sources, etc., and to be able to adjust the volume and EQ equalizer of each audio source separately to achieve personalized sound effect settings.

[0003] However, existing IP broadcast speakers adjust the volume and EQ of each input audio source individually in the following three ways:

[0004] Method 1: Use the display screen + remote control to make changes. Define the volume switch button, EQ type switch button, EQ frequency switch button and plus and minus buttons through the remote control, and use the display screen to observe the type of audio source, equalizer type, frequency and parameter value to make changes. This method is complicated to operate and does not have an intuitive display operation interface.

[0005] Method 2: Add a web access interface to the IP speaker and add a corresponding control interface to the web interface to select the volume and equalizer and adjust the parameters. However, this method requires a computer to be connected to the speaker's LAN to access the speaker's web terminal for operation, which is not convenient enough.

[0006] Method 3: Add a touch panel to the speaker and adjust it through the touch panel and design a separate interface. For IP broadcast speakers, this method will first increase a lot of costs, and secondly, IP broadcast speakers are usually hung on the wall during normal use, which is inconvenient to operate.

[0007] It can be seen that the existing methods of adjusting the volume of multiple input audio sources and the equalizer sound effects of IP broadcast speakers are either complicated to operate or require additional hardware, which cannot meet the convenience needs of users.

[0059] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0060] Figure 1 A structural diagram of an IP broadcast speaker for implementing audio adjustment provided in an embodiment of the present application, such as Figure 1 As shown, the IP broadcast speaker may include:

[0061] MCU, DSP audio processing chip, digital power amplifier module and speaker.

[0062] Among them, MCU (Microcontroller Unit) is a microcontroller unit, which can be used as the main control center. MCU can have a first serial port and a second serial port. The first serial port can be used to control the DSP audio processing chip, and the second serial port can be used for signal transmission to receive the command signal transmitted by other receiving modules. The DSP audio processing chip is connected to the MCU, which can be connected through the SPI bus. When the broadcast server sends the network audio stream signal to the terminal through the network, the network audio stream signal can be transmitted to the DSP audio processing chip through the MCU via the SPI bus. The use of the SPI bus does not require the DAC (Digital-to-Analog Converter) of the analog audio, and then the DSP audio processing chip performs further processing. The DSP audio processing chip can be connected to the speaker through the digital power amplifier module. The DSP audio processing chip can have multiple channels, and different channels correspond to audio signals of different sound sources. The DSP audio processing chip can adjust the volume (gain) and equalizer parameter value of the sound source for each channel. After the adjustment or modification is completed, it can be transmitted to the digital power amplifier through the I2S signal for decoding and output, and further played by the speaker.

[0063] based on Figure 1 The structure of the IP broadcast speaker shown in the figure, the embodiment of the present application provides a method for implementing audio adjustment of the IP broadcast speaker, such as Figure 2 As shown, the process of implementing the method may include:

[0064] Step S110: Acquire an audio signal and send the audio signal to a channel in a DSP audio processing chip.

[0065] The channel corresponds to the source type of the audio signal.

[0066] Specifically, Figure 3As shown, if the audio signal is input from a Bluetooth audio source, the audio signal will be sent to the ADC1 channel in the DSP audio processing chip; if the audio signal is input from a 2.4G wireless microphone source, the audio signal will be sent to the ADC2 channel in the DSP audio processing chip; if the audio signal is input from a local line audio source, the audio signal will be sent to the ADC3 channel in the DSP audio processing chip.

[0067] When the audio signal is input from a network audio source, it is transmitted by the MCU to the DSP audio processing chip through the SPI bus, and the audio signal is also sent to the corresponding channel in the DSP audio processing chip.

[0068] Further, from Figure 3 It can be seen that when the audio signal comes from a Bluetooth audio source, a 2.4G wireless microphone audio source, and a local line input audio source, they all have corresponding input modules. Then, the IP broadcast speaker can also include a Bluetooth receiving module, a 2.4G wireless microphone receiving module, and a local line input module. Among them, the Bluetooth audio source audio signal corresponds to the Bluetooth receiving module, the 2.4G wireless microphone audio source audio signal corresponds to the 2.4G wireless microphone receiving module, and the local line input audio source corresponds to the local line input module.

[0069] Based on this, the process of obtaining audio signals is further introduced, which may include the following three situations:

[0070] The first method is to obtain the audio signal pushed from the Bluetooth audio source through the Bluetooth receiving module.

[0071] The second method is to obtain the audio signal input from the 2.4G wireless microphone sound source through the 2.4G wireless microphone receiving module.

[0072] The third method is to obtain the audio signal input from the local line input audio source through the local line input module.

[0073] Step S120, responding to the user's instruction to adjust the audio signal from the WeChat applet, controlling the DSP audio processing chip to adjust the volume and equalizer parameter value of the channel through the first serial port.

[0074] Specifically, the functions of the IP broadcast speaker can be pre-deployed in the WeChat applet so that users can adjust the audio they listen to through the WeChat applet.

[0075] Examples include Figure 4When the user is listening to audio and needs to adjust the audio parameters, he can open the WeChat applet and turn on Bluetooth to connect to the Bluetooth receiving module of the IP broadcast speaker. The IP broadcast speaker automatically identifies the audio source category to which the audio belongs. The user can freely modify the audio volume and equalizer parameters in the WeChat applet interface. In addition, other parameters can be set, such as playback priority, whether lighting is required, lighting effect binding, lighting speed, and lighting color. When the user selects the parameter to be adjusted, the MCU will receive the adjustment instruction and control the DSP audio processing chip through the first serial port to adjust the parameters of the corresponding channel.

[0076] Among them, the Bluetooth receiving module of the IP broadcast speaker can use a Bluetooth module with a data transparent transmission function. The Bluetooth module that supports data transparent transmission can transmit data instructions through Bluetooth connection via Bluetooth.

[0077] It is understandable that users do not need to adjust the audio through buttons without obvious labels, nor do they need to use additional equipment to assist in the adjustment. Audio adjustment can be achieved only on the WeChat mini program, meeting users' convenient and intuitive adjustment needs.

[0078] Step S130: Transmit the audio signal whose volume and equalizer parameter value have been adjusted to the digital power amplifier module via an I2S signal, so that the digital power amplifier module can decode and output the audio signal.

[0079] In addition, when users need to adjust other parameters besides audio in the WeChat mini program interface, they can also transmit through the WeChat mini program and directly control the MCU output.

[0080] The audio adjustment method of the IP broadcasting speaker provided in this embodiment obtains an audio signal and sends the audio signal to a channel in a DSP audio processing chip, wherein the channel corresponds to the source type of the audio signal. Further, in response to the user's instruction to adjust the audio signal from the WeChat applet, the DSP audio processing chip is controlled through the first serial port to adjust the volume and equalizer parameter value of the channel, and the audio signal with the volume and equalizer parameter value adjusted is transmitted to the digital power amplifier module via an I2S signal for decoding and output by the digital power amplifier module. It can be seen that the user can realize the audio output of the device on the WeChat applet, and can freely adjust the audio volume and equalizer parameter value without relying on the control operation on the hardware, making it more convenient to adjust the audio of the IP broadcasting speaker.

[0081] Furthermore, when the IP broadcast speaker is deployed on the WeChat applet, it has strong scalability. If various other parameters of the IP broadcast speaker need to be changed later, such as modifying the IP, gateway, SIP parameter settings, etc., you can add a corresponding modification interface to the WeChat applet and add a corresponding protocol to the IP broadcast speaker to quickly modify other setting parameters of the IP broadcast speaker.

[0082] In some embodiments of the present application, the above step S120, in response to the user's instruction to adjust the audio signal from the WeChat applet, controls the DSP audio processing chip through the first serial port to adjust the volume and equalizer parameter value of the channel, is further introduced. The process may include:

[0083] S1. Obtain an adjustment instruction transmitted from the Bluetooth receiving module to the MCU through the second serial port.

[0084] The adjustment instruction is an instruction initiated by the user from the WeChat applet to adjust the audio signal.

[0085] Examples include Figure 3 ,When the user turns on the Bluetooth connection to the Bluetooth receiving module of the IP broadcast speaker and issues an adjustment command, the command signal will be transmitted to the MCU through the second serial port UART1.

[0086] S2. Based on the adjustment instruction, the DSP audio processing chip is controlled through the first serial port to adjust the volume and equalizer parameter value of the channel.

[0087] Examples include Figure 3 After receiving the adjustment instruction, the MCU can transmit it to the DSP audio processing chip through the first serial port UART2, and control the DSP audio processing chip to adjust the volume and equalizer parameter value of the corresponding audio channel based on the adjustment instruction.
