In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The recording method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a schematic flowchart of a recording method provided in an embodiment of the present application, where the recording method is applied to an earphone.
As shown in fig. 1, the recording method includes:
step 101: a first input is received.
In an embodiment of the application, the headset supports a recording function, which records a sound upon receiving a first input for starting a recording mode.
The target electronic device is mainly used for storing audio recorded by the earphone, and a communication connection is established between the earphone and the target electronic device in the recording process. The target electronic device may include, but is not limited to: mobile phones, tablet computers, notebook computers, palmtop computers, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants, desktop computers, and the like, which are capable of establishing a communication connection with an earphone. The communication connection between the headset and the target electronic device may be a wired connection or a wireless connection. For wireless connection, a bluetooth connection or the like may be specifically used.
Step 102: and responding to the first input, acquiring the recorded audio received by the target microphone, and sending the recorded audio to the target electronic equipment.
And under the condition that the earphone receives a first input for starting a recording mode, controlling a target microphone to record, and sending a recording audio recorded by the target microphone to the target electronic equipment for storing a recording file.
In the embodiment of the present application, at least two microphones are disposed on the earphone, where the target microphone is one of the at least two microphones, and when the earphone is worn on the ear of the user, the target microphone is closer to the ear canal of the user than the other microphones, that is, the target microphone is the microphone closest to the ear canal of the user among all the microphones on the earphone.
In the embodiment of the application, utilize the microphone to record on the earphone, because the earphone has advantages such as small in size, quality are lighter, portable, consequently the user when utilizing the earphone to record self surrounding sound, wear the earphone in the ear can, the earphone will remove along with user's removal to sound around the user is recorded, has released user's both hands, is convenient for record. And under the condition that the user correctly wears the earphone on the ear, because the target microphone is closest to the ear canal position of the user, the recording is carried out through the target microphone, the obtained recording audio frequency can be closer to the sound heard by the user, and the authenticity of the recording is improved.
Alternatively, the target microphone described in the embodiments of the present application may be a feed-forward microphone on the headset.
Generally, a main microphone and a feedforward microphone (generally, an auxiliary microphone) are arranged on the earphone, and the main microphone is mainly used for collecting user voice during conversation, so that the main microphone needs to be designed: when the headset is worn on the user's ear, the position of the primary microphone on the headset brings it closer to the user's mouth. The feedforward microphone is mainly used for collecting call environment Noise, so that the Noise reduction system generates reverse sound waves equal to the environment Noise according to the environment Noise collected by the feedforward microphone, and the Noise in the call is neutralized, thereby achieving the purpose of Active Noise reduction (ANC). In order to effectively distinguish useful sounds (such as user voice) from ambient noise, the distance between the feedforward microphone and the main microphone is as large as possible, so that when the main microphone is designed to be located closer to the mouth of the user, the feedforward microphone can be designed to be located as far away from the mouth of the user as possible, and when the main microphone is designed to be located farther away from the mouth of the user, the feedforward microphone can be designed to be located closer to the ear of the user, so that: when the headset is worn on the user's ear, the location of the feedforward microphone on the headset brings it closer to the user's ear. Therefore, in the embodiment of the application, the feedforward microphone which can be closer to the ear of the user can be used for recording, so that the obtained recording can be closer to the sound heard by the user, and the reality of the recording is improved. In addition, the feedforward microphone is usually selected from microphones with high acoustic overload points and high signal-to-noise ratios, and therefore, the target microphone is also preferably the feedforward microphone in the embodiment of the present application.
Both parameters, the acoustic overload point and the signal-to-noise ratio, of the target microphone are described further below.
Optionally, in this embodiment of the present application, an Acoustic Overload Point (AOP) of the target microphone is greater than 130dB, so as to avoid distortion of microphone recording caused by too high sound pressure level of a recording scene (e.g., a large music concert).
The acoustic overload points refer to: when the Total Harmonic Distortion (THD) of the microphone output is equal to 10%, the sound pressure of the microphone input is large. The input with the sound pressure higher than the acoustic overload point can cause serious distortion of an output signal, so that the acoustic overload point of the target microphone is larger in the embodiment of the application so as to adapt to a recording environment with higher sound pressure.
Optionally, in this embodiment of the present application, a Signal to Noise Ratio (SNR) of the target microphone is greater than 60 dB.
Signal-to-noise ratio refers to the ratio of signal to noise. Generally, the larger the snr of the microphone, the lower the noise mixed in the signal, the higher the quality of sound reproduction, otherwise, the opposite is true, therefore, in the embodiment of the present application, in order to obtain better sound recording, the snr of the target microphone is set to be greater than 60dB, preferably 65 dB.
Optionally, in this embodiment of the present application, the operating bandwidth of the target microphone is: 20Hz to 20kHz, therefore, after receiving the first input, the recording method may further comprise: in response to the first input, the target microphone is controlled to receive the recorded audio at the target operating bandwidth, i.e., the target microphone is controlled to record at the target operating bandwidth.
Wherein, the value range of the target working bandwidth is as follows: greater than or equal to 20Hz and less than or equal to 20 kHz.
The frequency range of the sound heard by human ears is 20Hz to 20kHz, and in order to better record the sound heard by human ears, the working bandwidth of the target microphone is set to be 20Hz to 20kHz in the embodiment of the application. Wherein, in order to make the working bandwidth of the target microphone reach 20kHz, the sampling frequency of the target microphone is at least 44100 Hz.
Alternatively, the microphone on the earphone in the prior art is mainly designed for conversation, and the working bandwidth (e.g. 100Hz to 8kHz) required for conversation conflicts with the working bandwidth (up to 20kHz) required for recording, so that when recording is performed with the working bandwidth required for conversation, the recording file loses details of music such as heavy bass and treble, and it is difficult to find the hearing experience at that time during playback. In order to enable the working bandwidth of the target microphone to be adjusted to the working bandwidth required by recording when the target microphone is used for recording, the earphone can be designed to at least comprise two working modes, namely a call mode and a recording mode, then one codec is respectively arranged aiming at each working mode, and the sampling frequencies of different codecs are different, so that different working bandwidths are realized.
For example, as shown in fig. 2, in talk mode, the first codec in the target microphone 201 (i.e., codec1 in fig. 2) operates at a sampling frequency of 16kHz to achieve the required operating bandwidth of 100Hz to 8kHz for talk. In the recording mode, the second codec (i.e., codec2 in fig. 2) in the target microphone 201 operates at least at a sampling frequency of 44100Hz to achieve the desired 20Hz to 20kHz bandwidth of operation for recording.
Optionally, in this embodiment of the present application, the recording mode of turning on the earphone may at least adopt the following two modes:
the first method is as follows: the method comprises the following steps of starting a recording mode of the earphone through the electronic equipment which is in communication connection with the earphone, and comprises the following specific steps:
step 101: receiving a first input may include: and receiving an input signal sent by the target electronic equipment under the condition that the earphone establishes communication connection with the target electronic equipment. And after receiving the input signal, the earphone responds to the input signal, starts a recording mode and controls the target microphone to record.
Wherein the input signal described herein is used to control the headset to initiate a recording mode.
In the embodiment of the application, the user can start the recording function of the earphone through the application program used for controlling the earphone on the target electronic equipment. For example, an option of "start recording mode" is displayed in the target interface of the application program, after the user selects the option of "start recording mode", the target electronic device sends a first control signal (i.e., the input signal) to the earphone, and after receiving the first control signal, the earphone starts the recording mode. The target electronic equipment detects that the earphone starts the recording mode, the target electronic equipment can adjust the 'starting recording mode' in the target interface to be the 'closing recording mode', when a user wants to close the recording mode, the target electronic equipment can select the 'closing recording mode' in the target interface, then the target electronic equipment sends a second control signal to the earphone, and after the earphone receives the second control signal, the recording mode is closed. It is understood that the closing operation of the recording mode may also be performed in case the headset detects a disconnection of the communication connection with the target electronic device.
For the conversation mode of the earphone, the default working mode of the earphone can be set. The earphone switches the working mode from the conversation mode to the recording mode under the condition that the earphone receives a first control signal sent by the target electronic equipment. It can be understood that the target interface of the foregoing application program may also display an option of "start call mode", that is, the user may also control the headset to be in the call mode through the option of "start call mode".
As shown in fig. 2, during the recording process, the earphone may transmit the recorded audio to the target electronic device through the communication connection established between the earphone and the target electronic device, so that the target electronic device stores the recording file.
The second method comprises the following steps: the recording mode of the earphone is started by directly operating the earphone, and the method comprises the following specific steps:
step 101: receiving a first input may include: a first input to the headset by a user is received. And after receiving the first input, the earphone responds to the first input, starts a recording mode and controls the target microphone to record. Wherein the headset may receive the first input if a communication connection is established with the target electronic device.
The first input described herein may include, but is not limited to: touch operation and/or voice control instruction. For example, if an entity key for controlling the working mode is provided on the earphone, the first input may be a touch operation on the entity key; or a touch panel is arranged on the earphone, the first input can be touch operation executed on the touch panel and used for controlling the working mode; or the first input is a voice control instruction for controlling the working mode of the earphone, such as an 'on' voice instruction.
Optionally, after obtaining the recorded audio received by the target microphone and before transmitting the recorded audio to the target electronic device, the recording method may further include: and adjusting the gain value of the recording audio received by the target microphone according to a preset balance adjustment curve.
The target frequency response curve is obtained after the balance adjustment curve is superposed with the original frequency response curve of the target microphone, and the target frequency response curve is a straight curve.
Professional playback is often desired to play back the sound of the actual scene at that time, so the ideal frequency response curve of the target microphone is a flat curve, i.e. the target microphone does not amplify or reduce the sound in any frequency band. However, the target microphone is affected by the stacked structure, and the actual frequency response curve and the ideal frequency response curve of the target microphone are different. In order to eliminate the difference as much as possible, in the embodiment of the present application, adjustment and improvement may be performed through an Equalizer (EQ for short) in the earphone, and when the target microphone performs amplification processing of a certain multiple on an audio signal of a certain frequency band, the EQ performs reverse adjustment, that is, performs reduction processing of the same multiple on the audio signal of the frequency band; similarly, when the target microphone performs a reduction processing of a certain multiple on the audio signal of a certain frequency band, the EQ performs an amplification processing of the same multiple on the audio signal of the frequency band, thereby realizing that the audio signal of any frequency band is not amplified or reduced, and obtaining a target frequency response curve after the original frequency response curve of the target microphone is adjusted by the EQ.
As shown in fig. 3, the EQ adjustment curve (i.e., the equalization adjustment curve) and the original frequency response curve of the target microphone are symmetric curves, and the EQ adjustment curve is the target frequency response curve-original microphone curve.
Optionally, after adjusting the gain value of the recording audio received by the target microphone according to the preset equalization adjustment curve, the earphone may send the recording audio with the adjusted gain value to the target electronic device. In addition, the earphone can also send the recording audio after adjusting the gain value to the loudspeaker of the earphone, and play the recording audio through the loudspeaker.
When a user wears the earphone to record, the ear is generally blocked by the earphone. In some recording scenes (such as a concert), the live hearing experience of the user is affected by wearing the earphones for recording, and therefore, as shown in fig. 2, in the embodiment of the present application, in order to improve the live hearing experience of the user when the user wears the earphones for recording, the earphones can transmit the sound recorded by the target microphone to the speaker 202 (i.e., the loudspeaker) of the earphones, and the sound is played by the speaker 202 of the earphones in real time, so that the user can also hear the sound recorded on the spot when wearing the earphones for recording, and the user is immersed in hearing enjoyment, thereby avoiding the user missing the live audio-visual feast.
Optionally, in the embodiment of the present application, the stacking structure of the target microphone should be simplified to obtain a smaller front cavity, so as to prevent the high frequency peak from being excessively advanced and ensure the microphone operating bandwidth.
Among them, the stacking structure of the target microphone may be as shown in fig. 4, including: a housing 401, a microphone unit 402, a first sealing rubber pad 403, a second sealing rubber pad 404, a mesh cloth 405, and a Flexible Printed Circuit (FPC) 406. The microphone unit 402, the first sealing rubber pad 403, the second sealing rubber pad 404, the mesh cloth 405 and the flexible circuit board 406 are disposed in the housing 401. A sound inlet 4011 is formed in the housing 401, and the first sealing rubber pad 403, the mesh cloth 404, the second sealing rubber pad 405, the flexible circuit board 406, and the microphone unit 402 are sequentially disposed along a direction away from the sound inlet 4011 by using the sound inlet 4011 as a reference body.
Alternatively, the target microphone may be a Bottom-entry digital microphone (i.e., a Bottom digital microphone), which has both good signal-to-noise performance and a high acoustic overload point, and is advantageous for the design of the stacked structure, and the resonant peak frequency of the microphone is 20kHz later, and the-3 dB point is 50Hz earlier, which is advantageous for ensuring the operating bandwidth of the microphone. The frequency response curve of the bottom-entry digital microphone is shown in fig. 5.
Optionally, in this embodiment of the present application, the earphone may include: left earphone and right earphone, the target microphone can be respectively: a left channel microphone on the left earpiece and a right channel microphone on the right earpiece. In the recording mode, the left channel microphone collects left channel signals, and the right earphone collects the right channel microphone. Then, the left channel signal and the right channel signal can be mixed and synthesized to generate a stereo recording file.
Optionally, the types of earphones described in the embodiments of the present application may include, but are not limited to: over-the-ear headphones, on-the-ear headphones, in-ear headphones, and earbud headphones. In the case that the type of the headset is the aforementioned type, the headset according to the embodiment of the present application may also be a True Wireless Stereo (TWS) headset.
To sum up, in the embodiment of this application, utilize the microphone to record on the earphone, because the earphone has advantages such as small in size, quality are lighter, portable, consequently the user when utilizing the earphone to record self surrounding sound, wear the earphone in the ear can, the earphone will remove along with user's removal to sound around the user is recorded, has released user's both hands, is convenient for record. And under the condition that the user correctly wears the earphone on the ear, because the target microphone is closest to the ear canal position of the user, the recording is carried out through the target microphone, the obtained recording audio frequency can be closer to the sound heard by the user, and the authenticity of the recording is improved.
