For ease of description, the devices mentioned above are collectively referred to as electronic devices. The embodiments of the present application are described in detail below.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a method for detecting a microphone plugging hole provided in an embodiment of the present application, which is applied to a wireless headset. The wireless headset includes a first wireless headset and a second wireless headset. The earphone and the second wireless earphone include at least one speaker, and the first wireless earphone includes a microphone. As shown in the figure, the method for detecting the plugging of a microphone includes:

S201. When the wireless headset detects that the first wireless headset is in a worn state, control the speaker to emit first audio in a preset frequency band;

The wireless headset may determine that the first wireless headset is in the worn state by detecting contact between the first wireless headset and the contour of the ear through multiple proximity sensors or pressure sensors, or may be determined by the first The attitude parameter of the wireless headset is used to determine that the wireless headset is in the worn state, and the first wireless headset is also determined to be in the worn state by detecting a communication identifier that the first wireless headset is successfully connected to the electronic device. Wait, it is not uniquely limited here.

Wherein, when it is detected that the first wireless earphone is in a worn state, the wireless earphone controls the speaker to emit the first audio from a region outside the ear region of the speaker, so that the detection while using the earphone, for example, from the ear The leak hole in the back of the area emits the first audio. The leak hole is used to balance the air pressure inside and outside the sound cavity to prevent the diaphragm of the speaker from bulging or contracting due to the difference in air pressure before and after. The first audio frequency may be greater than 20000 Hz. Super audio, at this time the preset frequency band can be any frequency band above 20,000 Hz, or an audible sound that can be heard by human ears with a frequency between 20,000 Hz and 20 Hz. At this time, the preset frequency band can be 20,000 Hz to Any frequency band between 20 Hz is not limited here.

Wherein, when there is no ambient sound interference, the first audio may be an audible sound that can be heard by the human ear, and when there is ambient sound interference, the first audio may be the above-mentioned ultrasonic wave, wherein, The wireless earphone may have a built-in decibel detector to detect ambient sound volume to determine whether there is ambient sound interference. When the first audio is the above-mentioned ultrasonic wave, the first wireless earphone needs to control the speaker to emit the first sound when there is an obstruction. For an audio, the obstruction can be any object that can block the speaker within a certain range, for example, it can be a second wireless headset.

S202. In a preset period, the wireless headset receives the second audio in the preset frequency band through a microphone of the first wireless headset.

Wherein, the wireless headset receives the second audio in a preset frequency band through the microphone, instead of receiving the second audio in the full frequency band, which is beneficial to reducing the interference of the first audio in other audio frequency bands and improving the accuracy of the second audio.

In the preset period, within a preset period in which the first audio is emitted for a speaker of the wireless headset, the preset period may be within 1 s, within 5 s, and the like, which is not limited herein.

Wherein, when the first audio of the preset frequency band is an ultrasonic wave with a frequency greater than 20,000 Hz, the first audio can be diffracted in various directions when it passes through the obstruction after being emitted by the obstruction. Therefore, Even if the microphone is not in the direction in which the speaker is transmitting ultrasonic waves, the microphone can also receive the second audio corresponding to the first audio. At this time, the second audio is the audio diffracted by the first audio.

Wherein, the speakers and microphones of the first wireless headset and the second wireless headset are speakers and microphones that support ultrasonic transmission and reception, such as a microphone equipped with an ultrasonic microphone sensor, and the ultrasonic frequency band supported by the speakers and the microphone may be 30,000 Hz to Direct ultrasound at 20,000 Hz, not necessarily full-band ultrasound.

S203. The wireless headset determines that the microphone of the first wireless headset is in a plugged state according to the second audio.

The specific implementation manner for determining that the microphone of the first wireless headset is in the hole blocking state according to the second audio may be various. For example, it may be to determine the range of the second audio energy according to different preset frequency bands. When the energy of the second audio is not in the energy range, the microphone is blocked, or the range of the amplitude of the second audio may be determined according to different preset frequency bands. When the amplitude of the second audio is not in the amplitude range, determine The microphone plugging hole is not limited herein.

The process of determining that the microphone is in the plugged state may be performed by an electronic device that is communicatively connected with the wireless headset. When the electronic device determines the plugged state, the electronic device sends the result to the wireless headset.

It can be seen that, in the embodiment of the present application, when the wireless earphone is first detected that the first wireless earphone is being worn, the speaker is controlled to emit a first audio of a preset frequency band, and secondly, in a preset period, The microphone of the first wireless headset receives the second audio in the preset frequency band. Finally, it is determined that the microphone of the first wireless headset is in a plugged state according to the second audio. It can be seen that the wireless earphone can detect that the microphone is plugged only through the speaker without adding a hardware structure, which expands the function of the wireless earphone, improves the convenience and timeliness of the plugging detection, and also detects the plugging of the microphone. The state of the hole can prevent the user from incomplete speech data input caused by the inability to perceive the problem of the microphone when subsequently recording the voice.

In a possible example, the determining that the microphone of the first wireless headset is in a plugged state according to the second audio includes:

Determining a parameter difference between the first audio and the second audio, where the parameter difference includes any one or more of the following: a volume difference, an amplitude difference, a frequency difference, and an energy difference;

When it is detected that the parameter difference is greater than a preset difference threshold, it is determined that the microphone is in the hole blocking state.

Among them, audio is a kind of sound wave, and sound wave is a kind of mechanical wave. Therefore, there is energy in the sound wave itself. This energy can be calculated from the density, frequency, amplitude, and wave velocity of the propagating medium. The average value represents the energy of sound per unit area.

Among them, different preset frequencies may correspond to different preset difference thresholds, and the preset difference threshold may be an experience value or an experience value obtained by a technical developer based on multiple tests before the electronic device leaves the factory, and It is preset in the electronic device. For example, when the parameter difference is an amplitude difference, the preset difference threshold may be 10 micrometers, 15 micrometers, etc., which is not limited herein.

It can be seen that, in this example, the wireless headset determines the plugging state of the microphone through the relationship between the parameter difference between the first audio and the second audio and the preset difference threshold. The use of the difference is beneficial to reduce the interference of the environment on single data. The calculation is simple, which is helpful to improve the convenience and accuracy of the determination of the plugging state.

In a possible example, when it is detected that the first wireless headset is in a worn state, the control speaker emits first audio of a preset frequency band, including:

When it is detected that the first wireless headset is in a worn state, a first prompt message is sent, and the first prompt message is used to prompt a user to place the second wireless headset in a preset position, where the preset position is the A position of a speaker of the second wireless headset facing the microphone of the first wireless headset;

When the second wireless earphone is located at the preset position, controlling a speaker of the second wireless earphone to emit the first audio in the preset frequency band, and the preset frequency band is a frequency band in which an ultrasonic wave is located.

The first prompt message may be a preset voice message to prompt the user to place the second wireless headset in a preset position, and the preset voice message may be voice data preset in the wireless headset before the wireless headset leaves the factory. Alternatively, the electronic device may be notified by the wireless headset to output a text form as the first prompt message, etc., which is not limited here.

Wherein, the preset position is a position where a speaker of the second wireless earphone faces the microphone of the first wireless earphone, that is, a microphone of the first wireless earphone emits first audio toward the speaker of the second wireless earphone. Audio range.

Wherein, the wireless earphone detects that the second wireless earphone is located in the preset position, may be determined after the first prompt message is sent out for a period of time, and the second wireless earphone is already located in the preset position, or may be determined by a user For the touch operation of the first wireless headset or the electronic device, it is determined that the second wireless headset is already located in the preset position. The touch operation may be, for example, a user double-clicking the electronic device or double-clicking the first wireless headset. No restrictions.

It can be seen that, in this example, when the wireless earphone is in the worn state, the second wireless earphone is placed in a preset position where the first wireless earphone can receive the second audio, and the first audio is emitted through the speaker of the second wireless earphone, avoiding The first wireless headset cannot detect the situation of the microphone plugging during the wearing process, and the second wireless headset directly receives the second audio in the transmission direction of the first audio through the microphone of the first wireless headset without receiving the second audio reflected by the first audio. Audio, which helps improve the timeliness of hole plugging detection.

In a possible example, when it is detected that the first wireless headset is in a worn state, controlling the speaker to emit first audio in a preset frequency band includes:

Acquiring image information when detecting that the first wireless headset is in a worn state;

Determining whether there is an obstruction in a preset direction according to the image information, and the preset direction is a direction that matches the transmission direction of the first audio;

When the presence of the obstruction is detected, the speaker is controlled to emit the first audio in the preset frequency band, and the preset frequency band is a frequency band in which an ultrasonic wave is located.

The first wireless headset is provided with a camera to obtain image information, and the obstruction may be a person, an object, etc., which is not limited herein.

It can be seen that, in this example, the wireless headset determines whether there is an obstruction by acquiring image information. Controlling the first audio in the ultrasonic frequency band in the presence of the obstruction is beneficial to ensure that the first audio is diffracted. Two-tone audio improves the effectiveness of hole plugging detection.

In a possible example, after the determining that the microphone of the first wireless headset is in a plugged state according to the second audio, the method further includes:

Determining a distance parameter between the second wireless headset and the first wireless headset when a first acquisition instruction for the first voice data is received;

When detecting that the distance parameter is less than a preset distance threshold, notifying the second wireless headset to receive the first voice data;

Receiving the first voice data from the second wireless headset.

Wherein, determining a distance parameter between the second wireless headset and the first wireless headset may determine a signaling transmission duration through a signaling interaction between the first wireless headset and the second wireless headset, and according to the signaling transmission The duration and the transmission speed determine the distance parameter between the first wireless headset and the second wireless headset.

It can be seen that, in this example, after determining that the microphone is in a plugged state, the wireless headset detects the distance parameter between the second wireless headset and the first wireless headset when receiving the first voice data acquisition instruction. When the distance parameter is less than a preset distance threshold At this time, switching the second wireless headset to receive the first voice data is beneficial to improving the integrity of the first voice data acquisition.

When receiving a second acquisition instruction for the second voice data, determining whether the microphone of the second wireless headset is in the plugged state;

When receiving the report information that the microphone of the second wireless headset is in the hole blocking state, a second prompt message is sent, and the second prompt message is used to prompt the user to place the second wireless headset in the first A wireless headset is located within a preset range;

When it is detected that the second wireless headset is located within the preset range where the first wireless headset is located, controlling the microphone of the first wireless headset and the microphone of the second wireless headset to perform a pickup operation;

The second voice data is determined according to first reference voice data picked up by a microphone of the first wireless headset and second reference voice data picked up by a microphone of the second wireless headset.

The specific implementation manner of determining that the microphone of the second wireless headset is in the hole blocking state is the same as the detection method of determining that the microphone of the first wireless headset is in the hole blocking state, and details are not described herein.

The report information is information about the second wireless earphone being in a hole blocking state sent by the second wireless earphone to the first wireless earphone.

The second prompt message may be a preset voice message prompting the user to place the second wireless headset in a preset range, and the preset voice message may be voice data preset in the wireless headset before the wireless headset leaves the factory, or The electronic device may be notified by the wireless headset to output a text form as the second prompt message, etc., which is not limited here.

Wherein, the specific implementation manner of detecting that the second wireless headset is located within the preset range where the first wireless headset is located is the same as the specific implementation manner of determining that the second wireless headset is located at the preset position, I won't go into details here.

The specific implementation manner of determining the second voice data according to the first reference voice data picked up by the microphone of the first wireless headset and the second reference voice data picked up by the microphone of the second wireless headset may be various. For example, it may be judged that the first reference voice data and the second reference voice data have actual voice durations with amplitude fluctuations, and the reference voice data with a longer actual voice duration is determined as the voice data, or may be the first reference The voice data and the second reference voice data are synthesized into the voice data, which is not limited herein.

It can be seen that, in this example, when the first wireless headset and the second wireless headset are in the plugged state, the first wireless headset and the second wireless headset collectively pick up voice data, and obtain the first The determination of the second voice data by the reference voice data and the second reference voice data obtained by the second wireless headset is conducive to ensuring the integrity of the second voice data and effectively ensuring the complete semantics of the second voice data.

In this possible example, the determining the second voice data according to the first reference voice data picked up by a microphone of the first wireless headset and the second reference voice data picked up by a microphone of the second wireless headset includes: :

Dividing the first reference voice data picked up by the microphone of the first wireless headset into a plurality of first data fragment groups according to a first time interval;

Dividing the second reference voice data picked up by the microphone of the second wireless headset into a plurality of second data fragment groups according to a second time interval;

The second voice data is combined according to the first data segment group and the second data segment.

The first time interval may be, for example, 1 s, 5 s, and the like, and the second time interval may be the same as the first time interval or different from the first time interval.

A specific implementation manner of combining the first data segment group and the second data segment into the second voice data may be the second data corresponding to each time in the first data segment group. The data segments in the segment group are compared to determine that the data segment with a large amount of data in the same time period is the data segment at the time corresponding to the voice data, for example, the data segment corresponding to 0s-5s in the first data segment group The amount of data on the data segment is 0bit, and the amount of data on the data segment corresponding to 0s-5s in the second data segment group is 10bit, then the data segment corresponding to 0s-5s in the synthesized speech data is 0s- 5s corresponding data segment.

It can be seen that, in this example, the wireless headset divides the first reference voice data and the second reference voice data into a plurality of data segments, and synthesizes the first reference voice data and the second reference voice data by the time corresponding to the data segments. The second voice data is beneficial to improving the intelligence of obtaining the second voice data. When the microphones of the first wireless headset and the second wireless headset are both blocked, the integrity of the second voice data is further improved.
