Fig. 1 is a first flowchart illustrating a method for processing audio data according to an embodiment of the present application.

Step S102, when the electronic device is wirelessly charged and connected with the charging seat, the state parameters of the electronic device are detected.

The CPU (central processing unit) of the electronic device can determine whether the electronic device is wirelessly connected to the charging cradle, and the principle is as follows: the electronic device may include a first coil and the charging dock may include a second coil. When the electronic equipment is wirelessly charged and connected with the charging seat, the first coil is in communication connection with the second coil; when the electronic equipment is disconnected with the charging seat in a wireless charging mode, the first coil and the second coil stop being in communication connection. The CPU may determine whether the electronic device is wirelessly connected to the charging dock according to whether the first coil receives the communication signal from the second coil.

It should be noted that, when the electronic device is wirelessly charged and connected to the charging seat, the electronic device may be in a charging state, or may be in a non-charging state due to the full charge of the electric quantity, and the second coil will continuously transmit the communication signal to the first coil as long as the electronic device remains connected to the charging seat regardless of whether the electronic device is in the charging state.

The state parameters of the electronic device may include one or more of the following parameters: the state parameter of the horizontal and vertical screen states of the representation electronic equipment, the shielding state parameter of whether the sound outlet hole of the first loudspeaker module of the representation electronic equipment is shielded, and the like.

The state parameters representing the horizontal and vertical screen states of the electronic equipment can be acquired through a gravity sensor G-sensor positioned in the electronic equipment. The shielding state parameter for representing whether the sound outlet of the first loudspeaker module is shielded or not can be acquired by a sensor which is arranged inside the sound outlet in advance or surrounds the sound outlet. The sound outlet of the first speaker module can be arranged at the bottom of the electronic device or at two sides of the electronic device.

And step S104, determining whether the sound outlet hole of the first loudspeaker module of the electronic equipment is blocked or not according to the state parameters.

When the electronic equipment is wirelessly charged and connected with the charging seat, the state parameters of the transverse and vertical screen states of the electronic equipment can reflect whether the sound outlet of the first loudspeaker module of the electronic equipment is shielded or not.

The first speaker module is disposed at the bottom of the electronic device as an example: the electronic equipment is in wireless charging connection with the charging seat, the vertical screen of the electronic equipment is determined to be placed on the charging seat through state parameters representing the horizontal and vertical screen states of the electronic equipment, the bottom of the electronic equipment is connected with the charging seat, and a sound outlet hole of a first loudspeaker module arranged at the bottom is shielded by the charging seat; the electronic equipment is wirelessly charged and connected with the charging seat, the transverse screen of the electronic equipment is determined to be placed on the charging seat through the state parameters of the transverse and vertical screen states of the electronic equipment, one side of the electronic equipment is connected with the charging seat, and the sound outlet hole of the first loudspeaker module arranged at the bottom is not shielded by the charging seat.

Optionally, the state parameter comprises a first state and a second state; under the condition that the electronic equipment is in a first state, the electronic equipment is placed on the charging seat in a vertical mode, and the sound outlet hole of the first loudspeaker module is shielded by the charging seat; under the condition that the electronic equipment is in the second state, the transverse screen of the electronic equipment is placed on the charging seat, and the sound outlet hole of the first loudspeaker module is not shielded.

In the following, taking an electronic device as a mobile phone as an example, the definition of the bottom of the electronic device and one side of the electronic device in the embodiment of the present application is described. The commonly used mobile phone can be regarded as a cuboid with six sides, one of the six sides of the cuboid is a mobile phone screen, and the mobile phone screen can be used for displaying a user operation interface of the mobile phone. One surface, namely the bottom of the mobile phone, of four surfaces adjacent to the mobile phone screen in the cuboid, which is close to the right lower side of the user operation interface; the side close to the right upper side of the user operation interface is the top of the mobile phone; the side close to the right left side or right side of the user operation interface is the side of the mobile phone.

The first state can be a vertical screen state, and when the electronic equipment is wirelessly charged and connected with the charging seat, the electronic equipment is in the vertical screen state, namely the electronic equipment is placed on the charging seat in a vertical screen mode. The electronic equipment is internally provided with a first loudspeaker module, and a sound outlet of the first loudspeaker module is positioned at the bottom of the electronic equipment. When the electronic equipment vertical screen is placed on the charging seat, the bottom of the electronic equipment is contacted with the charging seat, and the sound outlet hole positioned at the bottom is shielded by the charging seat.

The second state can be a horizontal screen state, and when the electronic device is wirelessly charged and connected with the charging seat, the electronic device is in the horizontal screen state, that is, the horizontal screen of the electronic device is placed on the charging seat. The electronic equipment is internally provided with a first loudspeaker module, and a sound outlet of the first loudspeaker module is positioned at the bottom of the electronic equipment. When the electronic equipment vertical screen is placed on the charging seat, one side of the electronic equipment is in contact with the charging seat, and the sound outlet hole positioned at the bottom is not shielded by the charging seat.

The following may specifically describe this embodiment with reference to fig. 2, fig. 3, and fig. 4: fig. 2 is a first physical diagram of an electronic device connected to a charging dock according to an embodiment of the present application. Fig. 3 is a second physical diagram of an electronic device connected to a charging dock according to an embodiment of the present application. Fig. 4 is a schematic frequency-loudness diagram of an electronic device playing audio data in different states according to an embodiment of the present application.

As shown in fig. 2, the electronic device 201 is connected to the charging cradle 202, and the electronic device 201 is in a landscape state. As shown in fig. 3, the electronic device 201 is connected to the charging dock 202, and the electronic device 201 is in a vertical screen state.

The sound outlet of the first speaker module is located at the bottom of the electronic device 201, and as shown in fig. 3, when the electronic device 201 is wirelessly charged and connected with the charging seat 202 and the electronic device 201 is in a vertical screen state, the sound outlet of the first speaker module is shielded by the charging seat 202; as shown in fig. 2, when the electronic device 201 is wirelessly charged and connected to the charging stand 202 and the electronic device 201 is in a landscape state, the sound outlet of the first speaker module is not blocked.

As shown in fig. 4, in the graph, the frequency is used as an abscissa, the unit is Hz, the loudness of sound is used as an ordinate, a curve 401 is a frequency-loudness curve when the electronic device is wirelessly connected to the charging stand and the electronic device is in a landscape state, and a curve 402 is a frequency-loudness curve when the electronic device is wirelessly connected to the charging stand and the electronic device is in a portrait state.

As can be seen from fig. 4, when the frequency is greater than the specific frequency, the loudness corresponding to the curve 402 is greatly decreased, which is understood that the high frequency response of the curve 402 is significantly decreased, so that the loudness corresponding to the curve 401 is significantly greater than the loudness corresponding to the curve 402. The subjective perception that the user listens to the audio data corresponding to curve 402 is that the sound is muffled and not clear enough. The specific frequency may be 3000 Hz.

It should be noted that, if the electronic device is not connected to the charging seat, the sound outlet of the first speaker module cannot be blocked by the charging seat, and it is not necessary to detect the horizontal and vertical screen states of the electronic device.

In another embodiment, if the sound outlet of the first speaker module is disposed at one side of the electronic device, and when the electronic device is connected to the charging seat and the electronic device is in the horizontal screen state, the sound outlet is blocked by the charging seat, then in the frequency-loudness schematic diagram shown in fig. 4, the curve 401 is a frequency-loudness curve when the electronic device is connected to the charging seat and the electronic device is in the vertical screen state, and the curve 402 is a frequency-loudness curve when the electronic device is connected to the charging seat and the electronic device is in the horizontal screen state, which is opposite to the aforementioned embodiment in which the sound outlet of the first speaker module is disposed at the bottom of the electronic device, and is not repeated here.

Before detecting a state parameter of the electronic device, the electronic device may receive a first instruction; the first instruction is used for instructing the electronic equipment to play audio data.

In the electronic device, the execution subject performing the step of receiving the first instruction may be a user input unit. Namely, a user input unit of the electronic equipment receives a first instruction submitted by a user and sends the first instruction to a CPU of the electronic equipment.

The first instruction may be an instruction submitted by a user for the electronic device. The first instruction is used for instructing the electronic equipment to play audio data through the first loudspeaker module. The audio data may be audio data of a song or audio data of a video. And playing the audio data through the first loudspeaker module, namely, externally playing the audio data.

For example, the user gives an instruction to play song A to the mobile phone, or the user gives an instruction to play video B to the tablet computer.

Before receiving the first instruction, the electronic device may be wirelessly connected to the charging cradle or not connected to the charging cradle. That is, the wireless charging connection between the electronic device and the charging dock may occur before the electronic device receives the first command or after the electronic device receives the first command. The charging seat can be a charging device for wired charging or a charging device for wireless charging.

For example, the mobile phone is connected with a charging seat with a wireless charging function to wirelessly charge the mobile phone, and then receives a first instruction for instructing the mobile phone to play the song nail through the first speaker module. For another example, a first instruction for instructing the mobile phone to play audio data of the video b through the first speaker module is received, and then the mobile phone is placed on a charging stand for wireless charging.

The first instruction may carry a first identification. The first identifier may be used to query the first audio data to be played.

After step S104 is performed, one of step S106, step S108, and step S110 may be performed.

The charging seat can be a charging seat provided with the second loudspeaker module, and can also be a charging seat not provided with the second loudspeaker module.

If the charging seat is not provided with the second loudspeaker module, if the sound outlet hole of the first loudspeaker module of the electronic equipment is shielded, executing the step S106; if it is determined that the sound outlet of the first speaker module of the electronic device is not blocked, step S110 is executed.

If the charging seat is provided with the second loudspeaker module, if the sound outlet hole of the first loudspeaker module of the electronic equipment is determined to be blocked, executing the step S108; if it is determined that the sound outlet of the first speaker module of the electronic device is not blocked, step S110 is executed.

And S106, under the condition that the sound outlet of the first loudspeaker module is blocked and the charging seat is not provided with the second loudspeaker module, carrying out audio playing in a first audio playing mode, determining a target audio parameter from a plurality of prestored audio parameters, and carrying out audio playing in the target audio parameter.

The pre-stored multiple audio parameters may include a target audio parameter called when the sound outlet of the first speaker module is blocked, or may include a conventional audio parameter called when the sound outlet of the first speaker module is not blocked.

The target audio parameter and the conventional audio parameter may be audio parameters used for audio processing of the audio data when the electronic device plays the audio data out.

The first audio playing mode can be an audio playing mode which improves the audio playing effect by calling the target audio parameter to play audio under the condition that the sound outlet of the first loudspeaker module is blocked.

Optionally, playing audio with the target audio parameter includes: acquiring first audio data to be played; configuring an equalizer module in the electronic equipment according to the target audio parameters; performing gain processing on the first audio data through the configured equalizer module to obtain second audio data; and playing the second audio data.

The method includes the steps of performing real-time audio processing on first audio data to be played according to a target audio parameter, wherein the first audio data comprise a plurality of audio signals arranged in a time sequence, searching gain data corresponding to the frequency of each audio signal in the first audio parameter, configuring an equalizer module in the electronic equipment according to the gain data, performing gain processing on the output loudness of each audio signal in the first audio data by using the configured equalizer module, and playing second audio data by using the first audio data after the gain processing as the second audio data.

Fig. 5 is a circuit system framework diagram of an electronic device according to an embodiment of the present application. The circuit system is a circuit system which is embodied by circuit devices in the electronic equipment for executing the steps of the audio data processing method. As shown in the figure, the central processing unit CPU505 includes an instruction sending module 501 and an audio data transmission module 502, the audio data transmission module 502 is in communication connection with the first smart power amplifier 503, the instruction sending module 501 is connected with the first smart power amplifier 503, and the first smart power amplifier 502 is connected with the first speaker module 504. Wherein:

CPU505 is the control hub for the entire circuitry.

The instruction sending module 501 may be an I2C (Inter-Integrated Circuit, two-wire serial bus) module, and the CPU505 controls the first smart power amplifier 502 to operate through the instruction sending module 501.

The audio data transmission module 502 may be an I2S (Inter-IC Sound, integrated circuit built-in audio bus) module, and the CPU505 transmits the first audio data to the first smart power amplifier 502 through the audio data transmission module 502.

A first smart power amplifier 502 for driving a first speaker module 504. The "power amplifier" in the first smart power amplifier 802 refers to a power amplifier. The first smart power amplifier 502 may include a DSP (Digital Signal processing) module inside, and the DSP module may include at least an EQ (Equalizer) module. The EQ module is configured to adjust an output frequency response of the audio data, and may give different gains to audio signals at different frequency points, that is, perform gain processing on the audio signal according to gain data corresponding to the frequency point, for the audio signal at any frequency point.

The first speaker module 504 is configured to play the second audio data.

In specific implementation, the equalizer module in the electronic device in the step "configure the equalizer module in the electronic device according to the target audio parameter" may be an EQ module in a DSP module in the first smart power amplifier 502 in the circuit system, and the main execution body for executing the step "play the second audio data" may be the first speaker module 504 in the circuit system.

In other embodiments, the first smart power amplifier 502 does not include a DSP module inside, and the DSP module is located inside the CPU, then the equalizer module in the electronic device in the step "configure the equalizer module in the electronic device according to the target audio parameter" may be an EQ module in the DSP module in the CPU505 in the circuit system, and the execution subject for executing the step "play the second audio data" may be the first speaker module 504 in the circuit system. After the EQ module performs audio processing on the first audio data to generate second audio data, the EQ module sends the second audio data to the first smart power amplifier 502, and the first smart power amplifier 502 sends the second audio data to the first speaker module 504.

Optionally, the target audio parameter is predetermined by: under the condition that the electronic equipment is in wireless charging connection with the charging seat and the electronic equipment is in a first state, testing the output frequency response of the third audio data at each frequency point to obtain first frequency response data; under the condition that the electronic equipment is in the second state, testing the output frequency response of the third audio data at each frequency point to obtain second frequency response data; and determining the gain data of each frequency point according to the first frequency response data and the second frequency response data, and taking the gain data of each frequency point as a target audio parameter.

The target audio parameters may be predetermined before the electronic device is formally put into use. For any electronic equipment, when the electronic equipment is wirelessly charged and connected with the charging seat and the electronic equipment is in a first state, the sound outlet of the first loudspeaker module positioned at the bottom of the electronic equipment is shielded by the charging seat, and under the condition, the output frequency response of each frequency point of the third audio data is tested to obtain the first frequency response data. The third audio data may include a plurality of frequency points located in a preset frequency band, and the plurality of frequency points may be continuous or discrete. The preset frequency band may be a high frequency band greater than a specific frequency. The specific frequency is the same parameter as the specific frequency in the frequency-loudness curve shown in fig. 4 and can be determined by the frequency-loudness curve shown in fig. 4.

And under the condition that the sound outlet is not blocked, testing the frequency response of each frequency point of the third audio data to obtain second frequency response data. And determining the gain data of each frequency point according to the ratio of the second frequency response data to the first frequency response data, and counting the gain data of each frequency point to obtain the target audio parameters.

This may be explained in connection with fig. 6. Fig. 6 is a frequency-gain diagram of a first audio parameter according to an embodiment of the present application. As shown, the abscissa is frequency in Hz and the ordinate is gain in dB. From 3KHz up frequency, can give positive gain gradually, when 6KHZ, the gain has reached 15dB, has compensated because the high frequency signal of loss is stopped up by the charging seat to the sound outlet of first speaker module. Gain is understood to mean that the audio data of the processor is amplified according to the value of the gain. For example, when the gain is 6dB, the loudness of the processed audio data is twice the loudness of the audio data before processing; when the gain is 12dB, the loudness of the processed audio data is four times the loudness of the audio data before processing.

And S108, under the condition that the sound outlet of the first loudspeaker module is blocked and the charging seat is provided with the second loudspeaker module, carrying out audio playing in a second audio playing mode, and carrying out audio playing on the second loudspeaker module and the second loudspeaker module through the second loudspeaker module.

The second audio playing mode can be an audio playing mode which improves the audio playing effect by playing audio through the second loudspeaker module arranged on the charging seat under the condition that the sound outlet of the first loudspeaker module is shielded.

It should be noted that, in the case of using the second audio playing mode, the second speaker module is obviously not shielded, so the electronic device can call the conventional audio parameters to play the audio. The regular audio parameters may be the pre-stored audio parameters that are called when the sound outlet of the first speaker module is not blocked.

Step S110, when the sound outlet of the first speaker module is not blocked, performing audio playing in a third audio playing mode.

The third audio playing mode may be an audio playing mode in which audio playing is performed through the first speaker module of the electronic device under the condition that the sound outlet of the first speaker module is not blocked. Under the condition of adopting the third audio playing mode, the electronic equipment can call the conventional audio parameters to play the audio. The regular audio parameters may be the pre-stored audio parameters that are called when the sound outlet of the first speaker module is not blocked.

The audio playing effects of the first audio playing mode, the second audio playing mode and the third audio playing mode are the same when the first audio playing mode, the second audio playing mode and the third audio playing mode are specifically implemented.

Step S108 and step S110 can be explained with reference to fig. 7 and 8. Fig. 7 is a third physical diagram of an electronic device connected to a charging dock according to an embodiment of the present application. Fig. 8 is a circuit system framework diagram of a charging cradle according to an embodiment of the present application.

Referring to fig. 7, the electronic device 201 is connected to the charging cradle 202, and the electronic device handles the portrait screen state. The charging base 202 includes a sound outlet 203 of the second speaker module, and the sound outlet 203 is not blocked when the electronic device 201 is connected to the charging base 202. As shown in fig. 8, the charging stand comprises a bluetooth module 801, a second smart power amplifier 802 and a second speaker module 803.

In this embodiment, the charging cradle is modified, and a bluetooth module 801, a second smart power amplifier 802, and a second speaker module 803 shown in fig. 8 are added. The bluetooth module 801 is responsible for communication connection with the electronic device, receives audio data sent by the electronic device, and transmits the audio data to the second smart power amplifier 802. The second smart power amplifier 802 amplifies the received audio data and pushes the speaker module of the second speaker module 803 to output sound, which is emitted from the sound outlet of the second speaker module 803. Wherein, the second smart power amplifier 802, the power amplifier refers to a power amplifier.

For example, when the mobile phone is wirelessly charged, if the user wants to play music or video, it is determined whether the mobile phone is in the landscape mode or the portrait mode by the gravity sensor G-sensor in the mobile phone. If the mobile phone is in the horizontal screen mode, sound is played from the sound outlet of the first loudspeaker module of the mobile phone. If the mobile phone is in the vertical screen mode, the sound outlet of the first loudspeaker module does not output sound, the audio data is transmitted to the Bluetooth module of the charging seat through the Bluetooth module of the mobile phone, and the sound is emitted through the sound outlet of the second loudspeaker module on the charging seat. In the process of playing videos and music, when the gravity sensor G-sensor detects that the state of the mobile phone is converted from a vertical screen to a horizontal screen, or the CPU detects that the mobile phone is disconnected with the charging seat, the sound is switched back to the sound outlet of the first loudspeaker module of the mobile phone for output.

Optionally, when the electronic device is in the first state, the charging seat is not provided with the second speaker module, and it is detected that the electronic device is disconnected from the charging seat for wireless charging, the audio playing in the first audio playing mode is stopped, and the audio playing in the third audio playing mode is performed; when the electronic equipment is in a first state, the charging seat is provided with a second loudspeaker module, and the wireless charging connection between the electronic equipment and the charging seat is detected, the audio playing in a second audio playing mode is stopped, and the audio playing in a third audio playing mode is carried out; under the condition that the charging seat is not provided with a second loudspeaker module and the electronic equipment is detected to be switched from the first state to the second state, stopping playing the audio in the first audio playing mode and playing the audio in the third audio playing mode; and the charging seat is provided with a second loudspeaker module, and the audio playing in the second audio playing mode is stopped and the audio playing in the third audio playing mode is carried out under the condition that the electronic equipment is detected to be switched from the first state to the second state.

When the electronic equipment is in a first state, the charging seat is not provided with a second loudspeaker module, and the wireless charging connection between the electronic equipment and the charging seat is detected, the audio playing in a first audio playing mode is stopped, and the audio playing in a third audio playing mode is carried out; and under the condition that the charging seat is not provided with the second loudspeaker module and the electronic equipment is detected to be switched from the first state to the second state, stopping playing the audio in the first audio playing mode and playing the audio in the third audio playing mode.

During specific implementation, the charging seat is not provided with the second loudspeaker module, the electronic equipment can adopt the first audio playing mode or the third audio playing mode to play audio under different conditions, and in the initial state, the electronic equipment is wirelessly connected with the charging seat, and the electronic equipment is in the first state, so that the electronic equipment can be determined to play audio in the first audio playing mode. Then, the following two cases may occur:

(a1) the electronic equipment is detected to be disconnected with the charging seat for wireless charging connection, at the moment, although the electronic equipment is still in the first state, the electronic equipment is not placed on the charging seat any longer, so that the sound outlet hole of the first loudspeaker module of the electronic equipment is not shielded by the charging seat any longer, the electronic equipment stops playing audio in the first audio playing mode, and plays audio in the third audio playing mode.
