Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repetitive description will be omitted.
As shown in fig. 1, an embodiment of the present invention discloses a method for controlling a bluetooth headset, where the bluetooth headset is used for data transmission with a terminal device. The Bluetooth headset comprises an audio decoding module. The terminal equipment comprises an audio coding module. In this application, the terminal device and the bluetooth headset have already established data communication connection. The control method of the Bluetooth headset comprises the following steps:
s10, detecting whether the earphone power saving function of the terminal equipment is triggered, and obtaining the residual electric quantity value of the Bluetooth earphone. Specifically, for example, the terminal device may be a mobile phone or a tablet computer. In this step, it may be detected whether the power saving function of the headset of the mobile phone is triggered. The user can directly start the power saving function of the headset by touching through a setting page or a shortcut control page as shown in fig. 2. The shortcut control page can also comprise a vibration setting function, a screen capture function, a mobile data switch function, a mute setting function, a flashlight switch function, a Bluetooth switch function and the like.
The residual electric quantity value of the bluetooth headset obtained by the above method may be a residual electric quantity value of the bluetooth headset directly obtained by the terminal device after the terminal device establishes data connection with the bluetooth headset. Or the Bluetooth headset can send the residual electric quantity value of the Bluetooth headset to the terminal equipment.
S20, when the power saving function of the headset of the terminal device is triggered and/or the remaining power value is smaller than a first preset threshold, controlling the audio encoding module in the terminal device to switch from the first bit rate to the second bit rate, and sending a bit rate adjustment command to the bluetooth headset. Wherein the first bit rate is greater than the second bit rate. That is, the bluetooth headset analyzes and plays the received data at a lower bit rate, thereby achieving the purpose of saving electricity.
The controlling the audio encoding module to operate at the second bit rate by switching from the first bit rate may include reducing a sample data amount of data to be transmitted. That is, the amount of sampled data of the data to be encoded is reduced. In particular, the sampling frequency of the data to be transmitted is reduced, and/or the number of bits per sample is reduced. For example, the sampling frequency is reduced from 48khz to 24khz, and the number of bits of a single sample, i.e., the number of bits, is reduced from 24 bits to 16 bits.
And S30, after the Bluetooth headset receives the bit rate adjusting instruction, the Bluetooth headset controls the audio decoding module to switch from the first bit rate to work at the second bit rate. I.e., the audio decoding module of the bluetooth headset, also changes to decode at the same bit rate as the audio encoding module. Therefore, when the Bluetooth headset and the terminal equipment perform subsequent data transmission, the data with lower bit rate can be transmitted, namely, the tone quality of audio is reduced, the lower energy consumption is realized, and the battery endurance of the Bluetooth headset is prolonged.
It should be noted that, the first preset threshold, the first bit rate, and the second bit rate are not limited in this application, and those skilled in the art can set the threshold as needed. For example, the first preset threshold may be 30%, the first bit rate may be 990kbps, and the second bit rate may be 328 kbps.
In another embodiment of the present application, based on the above embodiment, as shown in fig. 3, the above method further includes the steps of:
s40, when the adjusted bit rate value reaches the preset minimum value, adjusting the size of the single frame during data transmission from the first frame size to a second frame size, where the second frame size is larger than the first frame size. Specifically, the size of each frame of data to be transmitted is adjusted on the premise that the basic sound quality is guaranteed and no space for descending exists. The processor of the Bluetooth headset only receives and transmits data when the processor is awakened. Therefore, the number of times of awakening the processor is reduced by increasing the size of each frame in the transmitted data, the running time of the processor can be effectively reduced, the function consumption of the Bluetooth headset is reduced, and the purpose of saving electricity is achieved.
Wherein the first frame size may be 100 bytes per frame and the second frame size may be 400 bytes per frame. The preset minimum value may be 127 kbps. This is not a limitation of the present application.
In another embodiment of the present application, based on the above embodiment, as shown in fig. 4, the above method further includes the steps of:
and S50, continuously detecting the residual electric quantity value of the Bluetooth headset.
And S60, when the residual electric quantity value is smaller than a second preset threshold value, the terminal device controls the audio coding module to switch from the second bit rate to work at the third bit rate, and sends a second bit rate adjustment instruction to the Bluetooth headset. The second bit rate is greater than the third bit rate. The first preset threshold is greater than the second preset threshold.
And S70, after the Bluetooth headset receives the second bit rate adjustment instruction, the Bluetooth headset controls the audio decoding module to switch from the second bit rate to work at a third bit rate.
That is, when the electric quantity of the earphone is further too small, the coding and decoding bit rate of the audio data is further reduced, so that the purpose of further saving electricity is achieved, and the cruising ability of the Bluetooth earphone is further improved.
It should be noted that, in the present application, neither the second preset threshold nor the third bit rate is limited, and those skilled in the art can set the threshold as needed. For example, the second preset threshold may be 20%, and the third bit rate may be 127 kbps.
In another embodiment of the present application, on the basis of the above embodiment, as shown in fig. 5, another bluetooth headset control method is disclosed. The control method includes steps S51, S52 and the above step S30.
Wherein, step S51 is: detecting whether the earphone power saving function of the terminal equipment is triggered or not, and acquiring the residual electric quantity value of the Bluetooth earphone; an ambient sound signal is collected.
Step S52 is: and when the earphone power saving function of the terminal equipment is triggered, and/or the residual electric quantity value is smaller than a first preset threshold value, and/or the amplitude reduction amplitude of the environmental sound signal is larger than a third preset threshold value, controlling an audio coding module in the terminal equipment to be switched from the first bit rate to work at the second bit rate, and simultaneously sending a bit rate adjusting instruction to the Bluetooth earphone. For example, when a user enters an office building environment from a street, the surrounding environment is quite at the moment, and audio data does not need to be transmitted at a high bit rate any more, so that the coding and decoding bit rate of the audio data can be reduced, and the purpose of saving power is achieved.
The third preset threshold is not limited in the present application. For example, the third preset threshold may be 15%.
In another embodiment of the present application, on the basis of the above embodiment, as shown in fig. 6, the above method further includes, before step S10, the steps of:
s101, collecting geographical position information of a user during a working day in a preset time period. For example, the geographical location information of the user during the last three months of monday to friday, that is, the path trajectory on the user's work road, may be collected.
S102, acquiring a first destination and a second destination which have the longest stay time in the geographical position information. For example, the first destination may be a home address of the user. The second destination may be a corporate address of the user.
S103, acquiring the public transportation information with the maximum use times between the first destination and the second destination of the user and the position area when the user is in the public transportation included in the public transportation information. For example, the public transportation means may be a subway, and the position area corresponding to the travel when the user is located on the subway is obtained. For example, if the user sits on the subway from the Nanjing road station to the civil farm station every day on duty, the travel track of the subway between the Nanjing road station and the civil farm station is the position area corresponding to the travel.
S104, when detecting that the user enters the position area from the outside of the position area, controlling an audio coding module in the terminal equipment to work at the first bit rate. That is, at this time, the user enters a noisy environment from a non-noisy environment, and at this time, if the user needs to easily hear the audio content, the sound quality is easy to be clearer. Therefore, the audio data is transmitted at a higher bit rate, so that the user can hear the audio content conveniently, and the user experience is improved.
Step S20 is: when the earphone power saving function of the terminal equipment is triggered, and/or the residual electric quantity value is smaller than a first preset threshold value, and/or when the situation that the user leaves the position area is detected, the audio coding module in the terminal equipment is controlled to be switched from the first bit rate to work at the second bit rate, and meanwhile, a bit rate adjusting instruction is sent to the Bluetooth earphone. Specifically, that is, when another condition is satisfied: and when the user is detected to leave the position area, namely, the user enters the non-position area from the position area, or the conditions are met, the bit rate of audio data transmission is reduced. For example, after the user gets off the subway, the user enters an office building, which shows that the user leaves a noisy environment at this time, and does not need a high bit rate to transmit audio data any more, and at this time, the bit rate of audio transmission is reduced on the premise that the user can hear audio content clearly, so that the purpose of saving power for the bluetooth headset is achieved.
As a preferred embodiment, step S20 is: when the earphone power saving function of the terminal equipment is triggered, and/or the residual electric quantity value is smaller than a first preset threshold value, and/or when the situation that the user leaves the position area and the reduction amplitude of the audio amplitude of the environment sound signal collected at the same time is larger than a fourth preset threshold value is detected, controlling the audio coding module in the terminal equipment to be switched from the first bit rate to work at the second bit rate, and sending a bit rate adjusting instruction to the Bluetooth earphone. Therefore, the accuracy of detection when the user environment is changed can be further improved, the audio transmission of the earphone can be controlled more accurately, and the good experience of the user can be better guaranteed.
The fourth preset threshold is not limited in the present application. For example, the fourth preset threshold may be 15%.
In another embodiment of the present application, on the basis of the above embodiment, before step S10, the method further includes the steps of:
and establishing a database of mapping relation between the preset scene label and the transmission bit rate. For example, the preset scene tags may include a live scene, a chat scene, and a music scene.
And intercepting the transmitted audio data to obtain an audio data fragment.
And identifying the audio data fragment to obtain a target scene label matched with the audio data fragment. The target scene label belongs to the preset scene label.
And obtaining a fourth bit rate matched with the target scene label according to the target scene label and the database.
And controlling the Bluetooth headset to perform data transmission with the terminal equipment at the fourth bit rate. For example, the target scene tag may be a live scene, where the low latency requirement is higher for the user than the sound quality. Therefore, the audio data can be transmitted at a relatively low bit rate, which is beneficial to improving the battery endurance of the Bluetooth headset and reducing the live broadcast delay. Still alternatively, when the user is listening to the broadcast, when the broadcast is playing music, the audio data may be transmitted at a higher bit rate. When the broadcast is playing the chat audio of the host, the user has relatively low requirement for the tone quality at the moment, and the audio data can be transmitted at a lower bit rate, so that the cruising ability of the Bluetooth headset battery can be improved.
The step of intercepting the transmitted audio data to obtain an audio data segment includes:
and intercepting the transmitted audio data for multiple times to obtain multiple audio data fragments.
The step of identifying the audio data segment to obtain the target scene tag matched with the audio data segment includes:
and respectively identifying the plurality of audio data fragments to obtain a plurality of scene labels, and taking the scene label with the largest number as a target scene label. Therefore, the accuracy of scene identification is improved, and the accuracy of the obtained target scene label can be improved.
It should be noted that any combination of all the above embodiments of the present application is within the scope of the present application.
The embodiment of the invention also discloses a Bluetooth headset control system, which comprises the Bluetooth headset and the terminal equipment. The terminal equipment comprises a first main control module and an audio coding module, and the Bluetooth headset comprises an audio decoding module.
The first master control module is used for detecting whether the earphone power saving function of the terminal equipment is triggered or not and acquiring the residual electric quantity value of the Bluetooth earphone; when the earphone power saving function of the terminal equipment is triggered and/or the residual electric quantity value is smaller than a first preset threshold value, controlling an audio coding module in the terminal equipment to be switched from the first bit rate to work at the second bit rate, and sending a bit rate adjusting instruction to the Bluetooth earphone.
