Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a terminal device, an audio control method, an electronic device, and a readable storage medium. Background Technology

[0002] Currently, mobile terminals are typically equipped with two miniature speakers: one at the top and one at the bottom (in portrait mode) or one on the left and one on the right (when rotated to landscape mode). The top and bottom speakers are used to play the left and right channel audio signals respectively in portrait mode, while the left and right speakers are used to play the left and right channel audio signals respectively in landscape mode. This means that even if the audio signal to be output includes low-frequency channel signals, it will be mixed in the Digital Signal Processor (ADSP) chip and then output as full-range channels. In other words, in this technology, mobile terminals can only output signals from two channels independently and cannot output signals from more than two channels. Summary of the Invention

[0006] Thirdly, an electronic device is provided, including a processor and a memory, the memory storing a program or instructions executable on the processor, the program or instructions, when executed by the processor, implementing the method as described in the second aspect.

Thus, by controlling each of the first audio output units to output audio signals of different channels via the first audio bus, and by controlling the second audio output unit to output audio signals of different channels via the second audio bus, multi-channel playback of multiple channels is achieved. Furthermore, this terminal device can output low-frequency audio signals in addition to outputting full-range audio signals, that is, by controlling the output of full-range audio signals and low-frequency audio signals via two sets of audio buses respectively, thereby achieving the output of low-frequency channel signals.

Detailed Implementation

[0014] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0015] The following description, in conjunction with the accompanying drawings, details a terminal device, audio control method, electronic device, and readable storage medium provided in this application through specific embodiments and application scenarios.

[0016] Figure 1The illustration shows a structural diagram of a terminal device provided in an embodiment of this application, which may include: a terminal body 110 and a baseband chip 115, a first audio bus 120, a second audio bus 130, at least two first audio output units 140 and a second audio output unit 150 disposed on the terminal body; wherein, the baseband chip 115 is connected to each of the first audio output units 140 through the first audio bus 120, and the baseband chip is connected to the second audio output unit 150 through the second audio bus 130, and each of the first audio output units 140 and the second audio output unit 150 is used to output audio signals of different channels.

[0017] In this embodiment, a first audio bus controls each first audio output unit to output audio signals of different channels, and a second audio bus controls the second audio output unit to output audio signals of different channels, thereby achieving multi-channel playback. The first audio bus 120 controls the output of full-range channel signals, which include all audio content from low to high frequencies. Each first audio output unit 140 corresponds to a different full-range channel signal. The second audio bus 130 controls the output of low-frequency channel signals, which only include low-frequency audio content. For example, assuming the audio signal to be output is 2.1 channels, 2.1 channels correspond to 3 independent channels, including 2 full-range channels and 1 low-frequency channel. That is, the "2" in "2.1" represents 2 full-range channels, which typically include a left channel and a right channel. The ".1" represents 1 low-frequency channel. For example, as... Figure 2 The diagram illustrates a 2.1-channel multi-channel playback configuration. The baseband chip 115 includes a first interface 1151 and a second interface 1152. The baseband chip 115 is connected to a first audio bus 120 via the first interface 1151 and to a second audio bus 130 via the second interface 1152. The first audio bus 120 is connected to two first audio output units 140. Each first audio output unit 140 and the second audio output unit 150 output signals for their respective channels. The second audio bus 130 is connected to the second audio output units 150, which output signals for the low-frequency channels. Each first audio output unit 140 includes a first audio amplifier unit 141 and a first output channel 142. Each second audio output unit 150 includes a second audio amplifier unit 151 and a second output channel 152. An output channel refers to an audio output device or unit, such as a speaker.

[0018] In one exemplary embodiment, the size of the first output channel 142 is larger than the size of the second output channel 152.

[0019] In one exemplary embodiment, the first audio power amplifier unit 141 and the second audio power amplifier unit 151 may have a built-in digital signal processing (DSP) chip for implementing digital audio signal separation, mixing, DAC (analog-to-digital conversion), low-pass filtering, power amplification, etc.

[0020] In one exemplary embodiment, this application also provides a layout diagram of the audio output units corresponding to different channels of the terminal device under different usage states, such as... Figure 3 The image shows a schematic diagram of the audio output unit layout of a terminal device in portrait mode for a 2.1 channel audio scenario; as shown... Figure 4 The diagram shows the layout of the audio output units of the terminal device in landscape mode in a 2.1-channel scenario. Therefore, in this embodiment, 2.1-channel multi-channel playback can be achieved whether the terminal device is rotated or not.

[0021] In one exemplary embodiment, the first audio bus 120 and the second audio bus 130 can be integrated circuit built-in audio buses (Inter-IC Sound, I2S). The I2S bus includes a serial clock line (Bit Clock, BCK), a frame clock line (Word Clock, WCK), and a serial data line (DATA), and can transmit two channels of sound simultaneously, namely the left channel and the right channel. For example, as... Figure 5 The diagram shown is a timing diagram of the I2S bus. In one exemplary implementation, as... Figure 6 As shown in this embodiment, the interfaces of the first audio bus 120 and the second audio bus 130 corresponding to the baseband chip 115 can be set to Master Mode to provide a clock signal (BLCK) and a frame synchronization signal (LRCLK). The first audio output unit 140 and the second audio output unit 150 are both set to Slave Mode to receive the clock signal (Bus Clock, BLCK) and the frame synchronization signal (Left-Right Clock, LRCLK) provided by the baseband chip 115. The frame clock signal LRCLK is used to switch between left and right channel data. LRCLK being "1" indicates that right channel data is being transmitted, and "0" indicates that left channel data is being transmitted. In an exemplary embodiment, the selection of left and right channels can be achieved by configuring the LRCLK register of the digital audio amplifier.

[0022] In this embodiment, a terminal device is provided, which may include: a terminal body and a baseband chip, a first audio bus, a second audio bus, at least two first audio output units, and a second audio output unit disposed on the terminal body; wherein, the baseband chip is connected to each of the first audio output units through the first audio bus, and the baseband chip is connected to the second audio output unit through the second audio bus. Each of the first audio output units and the second audio output unit is used to output audio signals of different channels. Thus, by controlling each of the first audio output units to output audio signals of different channels through the first audio bus, and by controlling the second audio output unit to output audio signals of different channels through the second audio bus, multi-channel playback of multiple channels is realized. Furthermore, the terminal device can output low-frequency audio signals on the basis of outputting full-range audio signals, that is, by controlling the output of full-range audio signals and low-frequency audio signals through two sets of audio buses respectively, the low-frequency channel signal output is realized.

[0023] In one implementation, such as Figure 7 As shown, the terminal device further includes: a control bus 160 and a switching unit 170; wherein, the baseband chip 115 is connected to the first terminal 171 of the switching unit 170 via the control bus 160, the second terminal 172 of the switching unit 170 is connected to the second audio output unit 150, the third terminal 173 of the switching unit 170 is connected to the first audio bus 120, the fourth terminal 174 of the switching unit 170 is connected to the second audio bus 130, and one of the third terminal 173 and the fourth terminal 174 of the switching unit 170 is connected to the second terminal 172 of the switching unit 170. For example, in... Figure 7 In the middle, the third terminal 173 is connected to the second terminal 172, such as Figure 8 As shown, the fourth terminal 174 is connected to the second terminal 172.

[0024] It is understood that the baseband chip 115 is used to control one of the third terminal 173 and the fourth terminal 174 of the switching unit 170 to be connected to the second terminal 172 via the control bus 160. For example, as... Figure 9As shown, assuming the audio signal to be output is 2.0 channel, the two first audio output units 140 output the full-range channel signal of the left channel and the full-range channel signal of the right channel, respectively. The baseband chip 115 also controls the third terminal 173 of the switching unit 170 to be connected to the second terminal 172 of the switching unit 170 via the control bus 160. In this way, the full-range channel signals of the left and right channels are simultaneously transmitted to the second audio output unit 150, mixed, and then output. All three channels work simultaneously, realizing multi-channel playback under 2.0 channel conditions. For example, as... Figure 10 As shown, assuming the audio signal to be output is 2.1 channels, the two first audio output units 140 output the full-frequency channel signal of the left channel and the full-frequency channel signal of the right channel, respectively. The baseband chip 115 also controls the fourth terminal 174 of the switching unit 170 to be connected to the second terminal 172 of the switching unit 170 through the control bus 160. In this way, the low-frequency channel signal in the audio signal to be output can be transmitted to the second audio output unit 150. The three channels work simultaneously to realize multi-channel playback under 2.1 channels.

[0025] In one exemplary embodiment, the terminal device may further include a control component, wherein the control component is used to control whether the second audio output unit 150 is activated. When the control component is activated, the second audio output unit 150 is enabled, and the second audio output unit 150 outputs a low-frequency channel signal. When the control component is deactivated, the second audio output unit 150 is prohibited from outputting a low-frequency channel signal, that is, the second audio output unit 150 is restricted to prevent it from working and thus from outputting a low-frequency signal. In this way, the user can customize whether or not a low-frequency channel signal needs to be output according to their needs.

[0026] In one exemplary embodiment, the control component may include at least one of a software control component and a hardware control component. The software control component may include at least one of the following: buttons on a terminal screen, buttons in a virtual keyboard, voice control buttons, gesture control buttons, etc. The hardware control component may include at least one of the following: physical buttons on a terminal device, gesture sensing control buttons on a terminal device, and other physical buttons. In one implementation, such as Figure 11 As shown, the terminal device may further include: a mixing processing unit 180 and a filtering unit 190; wherein the mixing processing unit 180 and the filtering unit 190 may be connected in series between the first audio bus 120 and the third terminal of the switching unit 170.

[0027] The mixing unit 180 combines audio signals from different channels and adjusts the balance between the channels to obtain a mixed audio signal. The filtering unit 190 filters the signal processed by the mixing unit 180 to allow low frequencies to pass through. For example, assuming the output audio signal is 2.0 channels, the two first audio output units 140 output the full-range signal of the left and right channels respectively. These signals are then processed by the mixing unit 180 to obtain the mixed audio signal. After processing by the filtering unit 190, the mixed audio signal is obtained. When the baseband chip 115 controls the third terminal 173 of the switching unit 170 to be connected to the second terminal 172 of the switching unit 170 via the control bus 160, the full-range signal is output through the second audio output unit 150. In this way, the signals from the left and right channels are mixed and filtered before being transmitted to the second audio output unit 150. All three channels operate simultaneously, achieving subwoofer playback in 2.0 channel mode. Therefore, in this embodiment, by adding a control bus 160 and a switching unit 170, multi-channel playback and subwoofer playback in any channel mode can be achieved.

[0028] Figure 12 This illustration shows a flowchart of an exemplary embodiment of the audio control method provided in this application, which can be derived from the above. Figures 1-11 Execution by the terminal device in any of the embodiments may include the following steps: S1210: By analyzing the audio signal, the corresponding channel signal is obtained.

[0029] It is understandable that after the terminal acquires the audio signal, it performs channel separation on the audio signal to obtain the channel signal corresponding to each channel.

[0030] S1220: In response to the determination that the number of channel signals is at least two, control each first audio output unit to output a different full-frequency channel signal, and use the switching unit of the terminal device to control the second audio output unit to output a low-frequency channel signal.

[0031] It is understood that when the number of channel signals is greater than or equal to two, each first audio output unit outputs a full-range channel signal corresponding to the channel type, while the second audio output unit needs to output a low-frequency channel signal based on the switching unit control. For example, refer to the above. Figure 9Assuming the audio signal to be output is 2.0 channel, the two first audio output units 140 output the full-range signal of the left channel and the full-range signal of the right channel, respectively. With the third terminal 173 of the switching unit 170 connected to the second terminal 172, the full-range signals of the left and right channels can be transmitted to the second audio output unit 150 after mixing and filtering. All three channels operate simultaneously, achieving multi-channel playback and low-frequency channel signal output in 2.0 channel mode. (Refer to the above...) Figure 10 Assuming the audio signal to be output is 2.1 channels, the two first audio output units 140 output the full-range channel signal of the left channel and the full-range channel signal of the right channel, respectively. When the fourth terminal 174 of the switching unit 170 is connected to the second terminal 172 of the switching unit 170, the low-frequency channel signal in the audio signal can be transmitted to the second audio output unit 150. The three channels work simultaneously to realize multi-channel playback under 2.1 channels and output of low-frequency channel signals.

[0032] In this embodiment of the application, the audio signal is parsed to obtain the channel signal corresponding to the audio signal. Then, in response to the judgment that the number of channel signals is at least two, each first audio output unit is controlled to output a different full-frequency channel signal, and the switching unit of the terminal device is used to control the second audio output unit to output a low-frequency channel signal, thereby realizing multi-channel playback under multi-channel and output of low-frequency channel signals.

[0033] In this embodiment of the application, controlling the first audio output unit and the second audio output unit to output different channel signals may include one of the following: (1) In one implementation, controlling each first audio output unit to output different full-frequency channel signals and controlling the second audio output unit to output low-frequency channel signals using the switching unit of the terminal device includes: in response to the determination that the channel signals include at least two full-frequency channel signals and the number of full-frequency channel signals is less than or equal to the number of first audio output units, controlling each first audio output unit to output the full-frequency channel signal of the corresponding channel type, and controlling the second audio output unit to output a first low-frequency channel signal using the switching unit, wherein the first low-frequency channel signal is obtained by mixing the at least two full-frequency channel signals.

[0034] In other words, if the number of full-range channel signals included in the channel signal is less than or equal to the number of the first audio output units, then each full-range channel signal can be output through the corresponding channel type audio output unit. At the same time, at least two full-range channel signals will be mixed and then the mixed first low-frequency channel signal will be output through the second audio output unit. In this way, low-frequency channel signals can be output on the basis of outputting full-range channel signals, thereby increasing the bass effect and bringing a more immersive experience to the user.

[0035] (2) In one implementation, the step of using the switching unit of the terminal device to control each first audio output unit to output different full-frequency channel signals and to control the second audio output unit to output low-frequency channel signals includes: in response to the determination that the channel signal includes a second low-frequency channel signal and at least one full-frequency channel signal, and the number of full-frequency channel signals is less than or equal to the number of first audio output units, controlling each first audio output unit to output the full-frequency channel signal of the corresponding channel type, and using the switching unit to control the second audio output unit to output the second low-frequency channel signal.

[0036] In other words, the channel signal includes a second low-frequency channel signal and at least one full-frequency channel signal. The second low-frequency channel signal can be output through the second audio processing unit, and each full-frequency channel signal can be output through the first audio output unit of the corresponding channel type, thus realizing the synchronous output of the low-frequency channel signal of the full-frequency channel signal.

[0037] In an exemplary embodiment, the method further includes: in response to a determination that the channel signal includes at least two full-range channel signals and the number of the full-range channel signals is greater than the number of the first audio output units, controlling each of the first audio output units to output the full-range channel signal of the corresponding channel type, and using the switching unit to control the second audio output unit to output a mixed channel signal, wherein the mixed channel signal is obtained by mixing a target channel signal among the at least two full-range channel signals, and the target channel signal is the full-range channel signal not output by the first audio output unit.

[0038] In other words, if the number of full-range channel signals included in the channel signal is greater than the number of the first audio output units, then at least some of the full-range channel signals in the two full-range channel signals will not be output normally. Therefore, the full-range channel signals that cannot be output normally, i.e. the target channel signals, can be mixed and processed, and then the mixed channel signals can be output through the second audio output unit. This ensures that the audio information is not lost as much as possible.

Figures 1-11 Execution by the terminal device in any of the embodiments may include the following steps: S1310: Obtain the audio source to be played.

[0044] The mixed channel signal is obtained by mixing the full-frequency channel signal corresponding to the left channel and the full-frequency channel signal corresponding to the right channel.

[0046] S1420: When the audio source to be played is a 2.1 channel, configure the channel type of the first audio output unit as the left channel, configure the channel type of the second audio output unit as the right channel, and configure the channel type of the third audio output unit as the low-frequency channel.

[0047] S1430: The fourth terminal of the control switching unit is connected to the second terminal.

[0048] S1440: Decode the audio source to be played using the decoder of the terminal device.

[0049] S1450: Output the full-range channel signal corresponding to the left channel through the first audio output unit, the full-range channel signal corresponding to the right channel through the second audio output unit, and the low-frequency channel signal through the second audio output unit.

[0050] The low-frequency channel signal is obtained by mixing and filtering the full-frequency channel signal corresponding to the left channel and the full-frequency channel signal corresponding to the right channel.
