The wireless earphone refers to an earphone without a traditional connecting wire, preferably refers to a TWS earphone (True Wireless Stereo true wireless stereophonic sound), comprising a Bluetooth earphone, an infrared earphone and the like, is perfected and developed by random wireless technology, and most manufacturers release wireless earphones under the brand flags, and the structure of the wireless earphone is shown in fig. 1 and comprises a left channel earphone, a right channel earphone and a pickup MIC.

The invention provides a recording method, which mainly uses the MIC of a wireless earphone or a mobile terminal to record by detecting the distance between the wireless earphone and the mobile terminal and switching the wireless earphone or the MIC of the mobile terminal according to the difference of the distances, so as to ensure that when the distance of the mobile terminal is far, the sound is recorded by the worn wireless earphone, and when the distance is near, the sound is recorded by the mobile terminal. Preferably, the mobile terminal is a smart phone.

To further illustrate the technical solution of the present invention, the following specific embodiments are provided with reference to fig. 2 and 3.

Example 1

According to one or more embodiments of the present invention, a recording method is provided in the embodiments of the present invention, which is applied to a mobile terminal connected with a wireless earphone (such as a TWS earphone), as shown in fig. 2, where the recording method in the embodiments of the present invention may at least include two steps S1 and S2:

s1, detecting the distance between the wireless earphone and the mobile terminal.

S2, dynamically calling the MIC of the wireless earphone or the mobile terminal according to the distance between the wireless earphone and the mobile terminal so as to record by utilizing the MIC of the wireless earphone or the mobile terminal.

Through this embodiment, when having solved the wireless earphone that links to each other with mobile terminal and recording simultaneously, the poor problem of recording sound tone quality has realized the record tone quality of better, has improved the recording experience of user when wearing wireless earphone.

Alternatively, in one embodiment of the invention,

step S1, detecting the distance between the wireless earphone and the mobile terminal is achieved in the following mode.

And S11, sending a detection signal through a loudspeaker of the mobile terminal. For example, signals of the ultrasonic or subsonic frequency band are emitted through the speaker of the handset. Since the ultrasonic or infrasound signal is not perceived by the user, i.e. does not affect the user experience, it is used to detect distance in this embodiment.

S12, controlling the pickup MIC of the wireless earphone to be started and recording the detection signal. For example, the current wireless earphone is connected with the mobile phone through bluetooth, the mobile phone sends a control signal to the wireless earphone through bluetooth, the pickup MIC is started, and the ultrasonic or infrasound signal sent by the mobile phone is recorded.

S13, acquiring the amplitude and the amplitude of the detection signal recorded by the pickup MIC of the wireless earphone, and determining the distance according to a mapping table of the amplitude and the amplitude of the detection signal and the distance between the wireless earphone and the mobile terminal.

After the wireless earphone records the detection signal, namely the ultrasonic or infrasound signal, the detection signal is returned to the mobile phone through Bluetooth, the amplitude and the amplitude of the detection signal, namely the amplitude and the amplitude of the audio signal waveform are analyzed at the mobile phone end, and the amplitude of the detection signal are used as distance values for representing the distance between the wireless earphone and the mobile terminal and are recorded in a mapping table.

The mapping table of this embodiment is established by the different amplitude values of the detected signals recorded by the sound pick-up MIC of the wireless earphone when the wireless earphone and the mobile phone are at different distances, in this embodiment, the minimum distance accuracy distinguishable by the amplitude change is used as the basic unit of the distance change, and then the distance value and the corresponding amplitude value are recorded in the process that the wireless earphone and the mobile phone are spaced from near to far until the distance is far enough to be difficult to distinguish the change of the amplitude value. For example as shown in the following table:

the present table data is only taken as an example, wherein the value is measured as a corresponding amplitude variation value by a distance variation determined by minimum distance accuracy, whereby a mapping table is constructed from pairs of distance values between nearest and measurable furthest distances and all measured amplitude magnitudes.

Thus, the distance between the wireless earphone and the mobile terminal can be detected.

Step S2, dynamically calling the MIC of the wireless earphone or the mobile terminal according to the distance between the wireless earphone and the mobile terminal, and recording by utilizing the MIC of the wireless earphone or the mobile terminal is realized by adopting the following steps S21-S22.

S21, comparing the distance between the wireless earphone and the mobile terminal with a distance threshold. That is, whether the earphone is close to or far from the mobile phone is judged by comparing the distance with the distance threshold. The method comprises the following three steps:

s211, indexing the amplitude threshold value in a mapping table according to the distance threshold value.

When the distance between the wireless earphone and the mobile phone is divided into far and near, a distance threshold is required to be determined for division, after the distance threshold is specified by the user, a corresponding amplitude value can be indexed from a constructed mapping table, if the distance threshold exists in the distance between the wireless earphone and the mapping table, the corresponding amplitude value can be directly indexed, if the distance threshold does not exist in the mapping table, the square of the difference can be respectively obtained by utilizing the values in the distance sequence between the distance threshold and the mapping table, and the distance value in the mapping table capable of enabling the square value of the difference to be minimum is selected from all the obtained value sequences of the square of the difference, and the amplitude value is indexed by the distance value and is used as the amplitude threshold.

S212, acquiring the amplitude and the amplitude of the detection signal recorded by the pickup MIC of the wireless earphone at preset time intervals.

Because the distance between the wireless earphone and the mobile phone may change at any time, the distance between the wireless earphone and the mobile phone is detected dynamically to be near or far, that is, the amplitude and amplitude of the detection signal recorded by the sound pickup MIC of the wireless earphone are obtained at fixed time intervals. For example, the mobile phone may acquire the amplitude and magnitude of the detection signal recorded by the wireless headset every 10 seconds.

S213, comparing the amplitude value of the detection signal with the amplitude threshold value.

The amplitude threshold value and the amplitude value of the detection signal are obtained by the processing in steps S211 and S212, and the magnitudes of the two are compared.

S22, calling a pickup MIC of the wireless earphone if the distance is larger than the distance threshold; and calling the pickup MIC of the mobile terminal if the distance is smaller than or equal to the distance threshold value.

The distance and the distance threshold can be compared through S21, if the distance is larger than the distance threshold, namely, the distance between the mobile phone and the wireless earphone is far, the pickup MIC of the wireless earphone worn by the user is called to record, and if the distance is smaller than or equal to the distance threshold, namely, the distance between the mobile phone and the wireless earphone is near, the pickup MIC of the mobile phone is called to record.

According to the embodiment of the invention, the distance condition between the wireless earphone and the mobile terminal is detected, through the information, the pick-up MIC of the system recording scene is dynamically invoked, so that the basic function of the recording function is not influenced, the recording tone quality of the recording function after the user wears the wireless earphone can be improved as much as possible, and the user experience and the product satisfaction degree are improved.

the first step: after the user connects the mobile phone with the wireless earphone, the recording function is started.

And a second step of: the handset speaker emits an ultrasonic or infrasound detection signal s1.

And a third step of: the wireless earphone pick-up MIC is turned on and picks up the detection signal s1.

Fourth step: the wireless earphone sends the amplitude v1 of the picked-up detection signal s1 to the mobile phone end.

Fifth step: the system determines whether v1 is greater than a threshold v.

Sixth step: if yes, the system record calls the pickup MIC of the mobile phone terminal, and if not, the system record calls the pickup MIC of the wireless earphone.

According to the implementation manner of the embodiment, the system can dynamically call the pick-up MIC of the mobile phone or the wireless earphone through detecting the distance between the mobile phone and the wireless earphone, so that the sound recording can be ensured to obtain high sound quality, and the user experience can be improved.
