Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of intelligent electronic devices, and more particularly, to a control method for an earphone, a control device for an earphone, an earphone, and a computer-readable storage medium. Background Art

[0002] Noise-canceling earphones can reduce the impact of external ambient sounds on users. Most of the current noise-canceling earphones on the market support a transparency mode and a noise-canceling mode. Moreover, once the noise-canceling mode is turned on, the wearer's auditory perception ability of the external environment is reduced and they cannot respond to external requests for the wearer in real time. Here, it is necessary to switch the noise-canceling mode to the transparency mode to improve the wearer's perception of the external environment. However, when switching the noise-canceling mode to the transparency mode, it often requires the wearer to manually switch through a button on the earphone, and in certain specific situations, human intervention will affect the wearer's experience or reduce the concentration on the current task.

[0059] <Method Embodiment>

[0060] Figure 2 shows a control method of an earphone according to an embodiment of the present disclosure. This control method of the earphone can be implemented, for example, by the earphone 1000 as shown in Figure 1 , and the earphone 1000 can be a Bluetooth earphone.

[0061] As Figure 2 shown, the control method of the earphone provided in this embodiment may include the following steps S2100 to S2400.

[0062] Step S2100: When the earphone enters the noise reduction mode, obtain the first environmental sound signal picked up by the feedforward microphone.

[0063] Specifically, when the earphone enters the noise reduction mode, the earphone turns on the feedforward microphone and picks up the first environmental sound signal through the feedforward microphone. The first environmental sound signal includes the first voice signal and the first noise signal of the sound source. It can be understood that when the earphone enters the noise reduction mode, the wearer's perception of the external environment is very small, and it is basically impossible to hear the voice signal of the sound source in the external environment.

[0064] Step S2200: Determine the orientation information of the sound source relative to the wearer of the earphone according to the first voice signal.

[0065] In this embodiment, step S2200 of determining the orientation information of the sound source relative to the wearer of the earphone according to the first voice signal may further include the following steps S2210 to S2230:

[0066] Step S2210: Determine whether the first voice signal is a preset voice signal.

[0067] The preset voice signal is a voice signal that the wearer needs to respond to. When the first voice signal is a preset voice signal, it usually indicates that the wearer needs to respond to the sound source of the first voice signal. Here, it is necessary to improve the wearer's auditory perception of the external environment, that is, the wearer has a need to switch the earphone from the noise reduction mode to the transparent mode.

[0068] In one example, step S2210 of determining whether the first voice signal is a preset voice signal may further include: identifying the first voice signal to obtain the keyword in the first voice signal; matching the keyword with a preset keyword library; where the keyword library includes multiple keywords; when the keyword is matched, determine that the voice signal is a preset voice signal.

[0069] Among them, the keyword can most comprehensively summarize the information content of the first voice signal of the sound emitted by the sound source. The keyword can be time, address, name, etc.

[0070] In this example, when the wearer wears the earphone for the first time, the earphone outputs a first prompt message, which prompts the wearer to write multiple keywords to form a keyword library. Here, the wearer can write multiple keywords into the earphone according to the first prompt message to form a keyword library. For example, the wearer can write multiple keywords into the earphone through the application corresponding to the earphone to form a keyword library. When the wearer wears the earphone subsequently and the earphone enters the noise reduction mode, the earphone turns on the feedforward microphone, picks up the first environmental sound signal through the feedforward microphone, and extracts the first voice signal of the speaker from the first environmental sound signal. At the same time, semantic recognition is performed on the first voice signal to extract the keyword in the first voice signal. If the keyword is in the preset keyword library, it is determined that the first voice signal is a set voice signal.

[0071] In one example, the step S2210 of determining whether the first voice signal is a set voice signal may further include: matching the first voice signal with a preset voice signal library; wherein, the voice signal library includes multiple voice signals; when the voice signal is matched, it is determined that the first voice signal is a set voice signal.

[0072] In this example, when the wearer wears the earphone for the first time, the earphone outputs a second prompt message, which prompts the wearer to record multiple voice signals to form a voice signal library. Here, the wearer can record multiple voice signals into the earphone according to the second prompt message to form a voice signal library. When the wearer wears the earphone subsequently and the earphone enters the noise reduction mode, the earphone turns on the feedforward microphone, picks up the first environmental sound signal through the feedforward microphone, and extracts the first voice signal of the speaker from the first environmental sound signal. At the same time, if the first voice signal is in the preset voice signal library, it is determined that the first voice signal is a set voice signal.

[0073] Step S2220, when the first voice signal is a set voice signal, control the earphone to switch to the normal mode.

[0074] Specifically, when the first voice signal is a set voice signal, the earphone is switched to the normal mode. When the earphone is in the normal mode, the earphone has a certain playback volume and can also perceive the external environment to a certain extent.

[0075] Step S2230, when the earphone enters the normal mode, determine the orientation information of the speaker relative to the wearer of the earphone.

[0076] In this embodiment, when the earphone enters the normal mode in step S2230, determining the orientation information of the sound source relative to the wearer of the earphone may further include the following steps S2231 to S2232:

[0077] Step S2231, when the earphone enters the normal mode, obtain the second ambient sound signals picked up by the left microphone and the right microphone.

[0078] Specifically, when the earphone enters the normal mode, the earphone turns on the left microphone and the right microphone, and picks up the second ambient sound signals through the left microphone and the right microphone. The second ambient sound signals include the second voice signal and the second noise signal of the sound source.

[0079] Step S2232, identify the second voice signal to obtain the orientation information of the sound source relative to the wearer of the earphone.

[0080] The orientation information of the sound source relative to the wearer of the earphone includes, for example but not limited to, the sound source is located in front of the left side of the earphone, the sound source is located in front of the right side of the earphone, the sound source is located behind the left side of the earphone, and the sound source is located behind the right side of the earphone.

[0081] Specifically, after the earphone obtains the second ambient sound signals picked up by the left microphone and the right microphone, it extracts the second voice signal of the sound source speaking from the first ambient sound signals, and identifies the second voice signal to obtain the orientation information of the sound source relative to the earphone.

[0082] Exemplarily, the left microphone and the right microphone of the earphone may pick up the second voice signal of the sound source at different times. For example, before the second voice signal of the sound source is picked up by the left microphone, the second voice signal of the sound source is likely to be picked up by the right microphone. Based on the time difference between the second voice signals picked up at the left microphone and the right microphone, the orientation information of the sound source relative to the earphone can be determined.

[0083] Step S2300, obtain the motion information of the wearer.

[0084] The motion information of the wearer may be the head motion information of the wearer. The head motion information of the wearer includes, for example but not limited to, the wearer turns the head to the left, turns the head to the right, turns around, raises the head, and lowers the head.

[0085] In this embodiment, when the wearer's head moves, the head motion information of the wearer can be detected according to the motion sensor on the earphone. The motion sensor may be a gyroscope. For example, when the wearer's head moves, the head motion information of the wearer can be determined according to the gyroscope signal.

[0086] Step S2400: When the orientation information and the motion information are the same, control the earphone to switch to the transparent mode.

[0087] In this embodiment, when the orientation information of the earphone relative to the wearer is consistent with the head motion information of the wearer, it indicates that the wearer turns towards the sound emitter. Here, the earphone automatically switches from the normal mode to the transparent mode. When the earphone enters the transparent mode, the wearer has the strongest perception ability of the external environment, thereby improving the wearer's auditory perception of the external environment and enabling the wearer to respond to external requests in a timely manner.

[0088] According to an embodiment of the present disclosure, when the earphone enters the noise reduction mode, it will obtain the environmental sound information picked up by the feedforward microphone, and determine the orientation information of the sound emitter relative to the wearer of the earphone according to the voice signal of the sound emitter in the environmental sound signal. At the same time, it obtains the motion information of the wearer, and when the orientation information and the motion information are the same, controls the earphone to switch to the transparent mode. That is, it can combine the motion information of the wearer and the orientation information of the sound emitter relative to the wearer of the earphone, and automatically switch the earphone from the noise reduction mode to the transparent mode when it is determined that the wearer has a need to respond to external requests, improving the wearer's auditory perception of the external environment and enabling the wearer to respond to external requests in a timely manner.

[0089] In one embodiment, the control method of the earphone according to the embodiment of the present disclosure further includes the following steps S3100 to S3200:

[0090] Step S3100: When the earphone enters the normal mode, control the timer to start counting down.

[0091] In this embodiment, when the first voice signal is the set voice signal according to the above step S2220, the earphone will be controlled to switch to the normal mode. When the earphone enters the normal mode, the earphone will control the timer to start counting down and execute the above step S2230 to determine the orientation information of the sound emitter relative to the wearer of the earphone.

[0092] Step S3200: After executing the above step S2400 to control the earphone to switch to the transparent mode when the orientation information and the motion information are the same, stop the countdown.

[0093] Step S3300: When the orientation information and the motion information are different, keep the earphone in the normal mode and switch the earphone to the noise reduction mode.

[0094] <Example>

[0095] Next, a control method of an example earphone is shown. In this example, combined with Figure 3, the control method of the earphone may further include:

[0096] Step S301, when the earphone is powered on for the first time, output a second prompt message; wherein, the second prompt message is used to prompt the wearer to input multiple voice signals to form a voice signal library.

[0097] Step S302, when the earphone enters the noise reduction mode, the earphone activates the feedforward microphone and picks up the first environmental sound signal through the feedforward microphone.

[0098] Step S303, extract the first voice signal of the sound-producing object from the first environmental sound signal.

[0099] Step S304, determine whether the first voice signal is in the voice signal library. If so, execute Step S305; otherwise, execute Step S314.

[0100] Step S305, when the first voice signal is in the voice signal library, control the earphone to switch to the normal mode.

[0101] Step S306, control the timer to start counting down.

[0102] Step S307, pick up the second environmental sound signal through the left and right microphones of the earphone, and extract the second voice signal of the sound-producing object from the second environmental sound signal to obtain the azimuth information of the sound-producing object relative to the wearer of the earphone.

[0103] Step S308, determine the head movement information of the wearer according to the gyroscope signal of the earphone.

[0104] Step S309, determine whether the head movement information and the azimuth information are consistent. If so, execute Step S310; otherwise, execute Step S311.

[0105] Step S310, control the earphone to switch to the transparent mode and stop counting down, and the process ends.

[0106] Step S311, keep the earphone in the normal mode.

[0107] Step S312, determine whether the timer has ended. If so, execute Step S313; otherwise, execute Step S308.

[0108] Step S313, switch the earphone to the noise reduction mode, and the process ends.

[0109] Step S314, keep the earphone in the noise reduction mode.
