For convenience of description, the above-mentioned devices are collectively referred to as electronic devices. The following describes embodiments of the present application in detail.
Referring to fig. 2, fig. 2 is a schematic flowchart of a microphone occlusion detection method, which is applied to a wireless headset including a first wireless headset and a second wireless headset, where the first wireless headset and the second wireless headset include at least one speaker, and the first wireless headset includes a microphone, as shown in the figure, the microphone occlusion detection method includes:
s201, when the wireless earphone detects that the first wireless earphone is in a worn state, controlling a loudspeaker to emit first audio of 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 an ear contour through a plurality of proximity sensors or pressure sensors, may also determine that the wireless headset is in the worn state by detecting attitude parameters of the first wireless headset, may also determine that the first wireless headset is in the worn state by detecting a communication identifier that the first wireless headset is successfully in communication with an electronic device, and the like, which is not limited herein.
When the first wireless earphone is detected to be worn, the wireless earphone controls the loudspeaker to emit a first audio frequency from a region outside an ear entering region of the loudspeaker, so that the condition of detection while using can be realized, for example, the first audio frequency is emitted from a leakage hole on the back of the ear entering region, the leakage hole is used for balancing the air pressure action inside and outside a sound cavity, and the diaphragm of the loudspeaker is prevented from bulging or collapsing due to the fact that the front air pressure and the back air pressure are different, the first audio frequency can be a super audio frequency with the frequency greater than 20000 Hz, the preset frequency band can be an arbitrary frequency band above 20000 Hz at the moment, the audible sound of human ears with the frequency between 20000 Hz and 20 Hz can be generated, the preset frequency band can be an arbitrary frequency band between 20000 Hz and 20 Hz at the moment, and no unique limitation is made here.
When the first audio is the ultrasonic wave, the first wireless earphone needs to control the loudspeaker to emit the first audio under the condition that a shielding object exists, and the shielding object can be any object capable of shielding the loudspeaker within a certain range, such as a second wireless earphone.
S202, in a preset time period, the wireless earphone receives a second audio frequency in the preset frequency band through a microphone of the first wireless earphone;
the wireless earphone receives the second audio in the preset frequency band through the microphone instead of receiving the second audio in the full frequency band, so that the interference of other audio frequency bands on the first audio is reduced, and the accuracy of the second audio is improved.
In the preset time period, the first audio is emitted for the speaker of the wireless headset, and the preset time period may be within 1s, within 5s, and the like, which is not limited herein.
When the first audio frequency of the preset frequency band is the ultrasonic wave with the frequency larger than 20000 Hz, due to the shielding of the shielding object, the first audio frequency can be diffracted in multiple directions when the first audio frequency is transmitted through the shielding object, so that even if the microphone is not positioned in the direction of transmitting the ultrasonic wave by the loudspeaker, the microphone can also receive the second audio frequency corresponding to the first audio frequency, and the second audio frequency is the audio frequency diffracted by the first audio frequency.
The speakers and microphones of the first wireless earphone and the second wireless earphone are speakers and microphones supporting ultrasonic transmission and reception, such as microphones carrying ultrasonic microphone sensors, and the ultrasonic frequency band supported by the speakers and microphones can be 30000 Hz to 20000 Hz direct ultrasonic waves without being full-band ultrasonic waves.
S203, the wireless earphone determines that the microphone of the first wireless earphone is in a hole blocking state according to the second audio.
The specific implementation manner of determining that the microphone of the first wireless headset is in the hole blocking state according to the second audio frequency may be various, for example, a range of energy of the second audio frequency may be determined according to different preset frequency bands, when the energy of the second audio frequency is not in the energy range, the microphone is determined to be in the hole blocking state, or a range of amplitude of the second audio frequency may be determined according to different preset frequency bands, when the amplitude of the second audio frequency is not in the amplitude range, the microphone is determined to be in the hole blocking state, which is not limited herein.
The process of determining that the microphone is in the hole plugging state may be performed by an electronic device in communication with the wireless headset, and when the electronic device determines the hole plugging state, the electronic device sends the result to the wireless headset.
It can be seen that, in the embodiment of the present application, the wireless headset firstly controls the speaker to emit the first audio frequency in the preset frequency band when detecting that the first wireless headset is in the worn state, secondly, receives the second audio frequency in the preset frequency band through the microphone of the first wireless headset in the preset time period, and finally, determines that the microphone of the first wireless headset is in the hole blocking state according to the second audio frequency. It is thus clear that wireless headset only through the speaker alright detect the microphone and be in the stifled hole state under the condition that does not increase hardware structure, has expanded wireless headset's function, has promoted the convenience and the promptness that the stifled hole detected, moreover, through the stifled hole state that detects the microphone, can avoid the user because of the incomplete condition of speech data input that the problem that can't perceive microphone existence leads to when follow-up input pronunciation.
In one possible example, the determining that the microphone of the first wireless headset is in a plugged-hole state based on the second audio includes:
determining parameter differences for the first audio and the second audio, the parameter differences including any one or more of: volume difference, amplitude difference, frequency difference and energy difference;
and when the parameter difference is detected to be larger than a preset difference threshold value, determining that the microphone is in the hole blocking state.
The sound frequency is a sound wave, and the sound wave is a mechanical wave, so that the sound wave has energy which can be calculated by the density, frequency, amplitude and wave speed of the propagating medium, namely, how much of the average value of the energy flowing through the medium per unit area per unit time represents the energy of the sound per unit area.
The different preset frequencies may correspond to different preset difference thresholds, where the preset difference thresholds may be empirical values, or empirical values obtained by a technical developer according to a plurality of tests before the electronic device leaves a factory, and are preset in the electronic device, for example, when the parameter difference is an amplitude difference, the preset difference thresholds may be 10 micrometers, 15 micrometers, and the like, and are not limited herein.
As can be seen, in this example, the wireless headset determines the hole blocking state of the microphone according to the relationship between the parameter difference between the first audio and the second audio and the preset difference threshold, and using the difference is beneficial to reducing the interference of the environment on a single datum, and is simple in calculation and beneficial to improving the convenience and accuracy of determining the hole blocking state.
In one possible example, when it is detected that the first wireless headset is in a worn state, the controlling the speaker to emit a first audio of a preset frequency band includes:
when the first wireless earphone is detected to be in a worn state, sending a first prompt message, wherein the first prompt message is used for prompting a user to place a second wireless earphone at a preset position, and the preset position is a position where a loudspeaker of the second wireless earphone faces a microphone of the first wireless earphone;
when the second wireless earphone is located at the preset position, the loudspeaker of the second wireless earphone is controlled to send the first audio of the preset frequency band, and the preset frequency band is the frequency band where the ultrasonic wave is located.
The first prompt message may be a preset voice message to prompt the user to place the second wireless headset at a preset position, where the preset voice message may be voice data preset in the wireless headset before the wireless headset leaves a factory, or the wireless headset may notify the electronic device that a text form is output as the first prompt message, and the like, and is not limited herein.
The preset position is a position where the speaker of the second wireless headset faces the microphone of the first wireless headset, that is, the microphone of the first wireless headset faces the speaker of the second wireless headset within an audio frequency range of the first audio frequency.
The detection by the wireless headset that the second wireless headset is located at the preset position may be that the second wireless headset is determined to have been located at the preset position after a period of time is sent out through a first prompt message, or may be that the second wireless headset is determined to have been located at the preset position by a user through a touch operation on the first wireless headset or the electronic device, where the touch operation may be, for example, an operation of the user double-clicking the electronic device or double-clicking the first wireless headset, which is not limited herein.
It can be seen that, in this example, when the wireless headset is in the state of being worn, place the second wireless headset at the preset position that the first wireless headset can receive the second audio, send first audio through the speaker of the second wireless headset, avoided the condition that first wireless headset can't detect the stifled hole of microphone in the wearing process, moreover, the microphone through first wireless headset directly receives the second audio in the transmitting direction of first audio, and need not receive the reflected second audio of first audio, be favorable to promoting the timeliness of stifled hole detection.
In one possible example, the controlling the speaker to emit the first audio of the preset frequency band when the first wireless headset is detected to be worn includes:
when detecting that the first wireless earphone is in a worn state, acquiring image information;
determining whether a shelter exists in a preset direction according to the image information, wherein the preset direction is a direction matched with the emission direction of the first audio;
when the shelter is detected to exist, the loudspeaker is controlled to send the first audio of the preset frequency band, and the preset frequency band is the frequency band where the ultrasonic wave is located.
The first wireless earphone is provided with a camera, image information can be acquired, and the sheltering object can be a person, an object and the like, which is not limited herein.
Therefore, in the example, the wireless headset determines whether the shielding object exists by acquiring the image information, the first audio frequency of the ultrasonic frequency band is controlled to be sent out under the condition that the shielding object exists, diffraction of the first audio frequency is guaranteed, namely the microphone can receive the second audio frequency, and the effectiveness of hole blocking detection is improved.
In one possible example, after determining that the microphone of the first wireless headset is in a plugged-hole state based on the second audio, the method further comprises:
determining a distance parameter between the second wireless headset and the first wireless headset when a first acquisition instruction for first voice data is received;
when the distance parameter is detected to be smaller than a preset distance threshold value, informing the second wireless earphone to receive the first voice data;
receiving the first voice data from the second wireless headset.
The determining of the distance parameter between the second wireless headset and the first wireless headset may be determining a signaling transmission duration through signaling interaction between the first wireless headset and the second wireless headset, and determining the distance parameter between the first wireless headset and the second wireless headset according to the signaling transmission duration and the transmission speed.
It can be seen that, in this example, after the wireless headset determines that the microphone is in the hole blocking state, when receiving the instruction for acquiring the first voice data, the wireless headset detects the distance parameter between the second wireless headset and the first wireless headset, and when the distance parameter is smaller than the preset distance threshold, the second wireless headset is switched to receive the first voice data, which is beneficial to improving the integrity of acquiring the first voice data.
In one possible example, after determining that the microphone of the first wireless headset is in a plugged-hole state based on the second audio, the method further comprises:
when a second acquisition instruction for second voice data is received, determining whether a microphone of the second wireless headset is in the hole blocking state;
when the reported information that the microphone of the second wireless earphone is in the hole blocking state is received, sending a second prompt message, wherein the second prompt message is used for prompting a user to place the second wireless earphone in a preset range of the position of the first wireless earphone;
when the second wireless earphone is detected to be located in the preset range of the position of the first wireless earphone, controlling a microphone of the first wireless earphone and a microphone of the second wireless earphone to carry out sound pickup operation;
and determining the second voice data according to the first reference voice data picked up by the microphone of the first wireless earphone and the second reference voice data picked up by the microphone of the second wireless earphone.
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 manner of determining that the microphone of the first wireless headset is in the hole blocking state, which is not described herein again.
The reported information is information that the second wireless earphone sends to the first wireless earphone and is about that the second wireless earphone is in a hole blocking state.
The second prompt message may be a preset voice message to prompt the user to place the second wireless headset within a preset range, where the preset voice message may be voice data preset in the wireless headset before the wireless headset leaves a factory, or the wireless headset may notify the electronic device that a text form is output as the second prompt message, and the like, and is not limited herein.
The specific implementation manner of detecting that the second wireless headset is located within the preset range of the position of the first wireless headset is the same as the specific implementation manner of determining that the second wireless headset is located at the preset position, which is not described herein again.
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, the actual voice time length with amplitude fluctuation in the first reference voice data and the second reference voice data may be judged, and the reference voice data with the longer actual voice time length may be determined as the voice data, or the first reference voice data and the second reference voice data may be synthesized into the voice data, which is not limited herein.
Therefore, in this example, when the first wireless headset and the second wireless headset are both in the hole plugging state, the wireless headset picks up the voice data through the first wireless headset and the second wireless headset together, and determines the second voice data through the first reference voice data acquired by the first wireless headset and the second reference voice data acquired by the second wireless headset together, which is beneficial 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 from 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 includes:
dividing the first reference voice data picked up by a microphone of the first wireless headset into a plurality of first data segment 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 segment groups according to a second time interval;
and combining the second voice data according to the first data fragment group and the second data fragment.
The first time interval may be, for example, 1s or 5s, and the second time interval may be the same as or different from the first time interval.
The specific implementation manner of combining the first data segment group and the second data segment into the second voice data may be to compare each data segment in the first data segment group with a data segment in the second data segment group corresponding to time, and determine that the data segments with a large amount of data in the same time period are the data segments corresponding to the voice data in the time, for example, the data amount on the data segments corresponding to 0s-5s in the first data segment group is 0bit, and the data amount on the data segments corresponding to 0s-5s in the second data segment group is 10bit, so that the data segments corresponding to 0s-5s in the synthesized voice data are the data segments corresponding to 0s-5s in the second data segment group.
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 into the second voice data according to the time corresponding to the data segments, which is beneficial to improving the intelligence of obtaining the second voice data, and further improves the integrity of the second voice data under the condition that the microphones of the first wireless headset and the second wireless headset are blocked.
