Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Bluetooth communication is widely used for short-distance data transmission due to its high transmission rate and security. Especially, the Bluetooth audio output device is applied to the connection between terminal equipment and Bluetooth audio output devices such as Bluetooth earphones and Bluetooth sound boxes, and the Bluetooth communication brings great convenience for users to use the audio devices. The current bluetooth device mainly includes two modes, namely a Headset Profile (HSP) mode and a hands-free Profile (HFP) mode, wherein the HSP mode is a basic mode of the bluetooth device, has a basic function of bluetooth communication, supports data transmission between the bluetooth device and a terminal device, and has a basic control function. The HFP mode adds more control functions on the basis of the HSP mode, so that the Bluetooth device can control the terminal device to have the functions of answering, hanging up, refusing to connect, dialing voice and the like.
In order to facilitate the use of a user, the Bluetooth device has a volume adjusting function, a volume adjusting button is configured on the Bluetooth device, and the user can adjust the audio volume output by the Bluetooth device by operating the volume adjusting button on the Bluetooth device. Meanwhile, the terminal equipment also supports remote volume adjustment of the Bluetooth equipment, after the terminal equipment is successfully matched with the Bluetooth equipment, the Bluetooth output volume is adjusted on the terminal equipment by a user after Bluetooth connection is realized, the operation can also be transmitted to the Bluetooth equipment, and the Bluetooth equipment adjusts the output audio volume according to the volume adjustment operation sent by the terminal equipment. Currently, both HSP and HFP bluetooth modes support these two volume adjustment modes.
However, in the current bluetooth volume adjustment method, whichever adjustment method is used, it is necessary for the bluetooth device to finally perform adjustment of the output volume. This requires that the bluetooth device be equipped with an associated hardware module for output volume adjustment, such as an audio amplification circuit. For example, if the user operates the volume adjustment button on the bluetooth device, the audio amplifier circuit in the bluetooth device will respond to the operation to adjust the output volume of the bluetooth device, and at the same time, the bluetooth device will also send the volume adjustment operation to the connected terminal device, so that the terminal device synchronously adjusts the bluetooth volume. If the user operates the volume adjusting button on the terminal equipment or selects to adjust the Bluetooth volume through touch control, the terminal equipment can update the Bluetooth volume on the terminal equipment and sends the adjusting operation to the connected Bluetooth equipment through Bluetooth connection, and the Bluetooth equipment controls the audio amplification circuit to adjust the output volume of the Bluetooth equipment according to the adjusting operation. The related hardware module configured in the bluetooth device will increase the cost of the bluetooth device, and in addition, will occupy the volume of the bluetooth device, and increase the power consumption of the bluetooth device.
The embodiment of the application provides a method and a device for adjusting the volume of Bluetooth equipment, which solve the problems existing in the volume adjustment of the existing Bluetooth equipment by optimizing the volume adjustment process of the Bluetooth equipment.
Fig. 1 is a flowchart of a first embodiment of a method for adjusting a volume of a bluetooth device according to an embodiment of the present application, and as shown in fig. 1, the method for adjusting a volume of a bluetooth device according to the present embodiment includes:
The volume adjustment method for the bluetooth device provided by the embodiment is applied to the terminal device connected with the bluetooth device. The terminal device is any terminal device capable of performing bluetooth connection with a bluetooth device, such as a mobile phone, a tablet computer, a music player, and the like. The bluetooth device connected with the terminal device is any device which can be connected with the terminal device through bluetooth and has an audio playing function, such as a bluetooth headset, a bluetooth sound box, a vehicle-mounted sound box and the like.
Before playing the audio on the terminal device by using the bluetooth device, the bluetooth device and the terminal device need to be connected through bluetooth first. The specific mode of connecting the bluetooth device with the terminal device can adopt any one of the current modes, and is not repeated in the application. However, before the bluetooth device is connected with the terminal device, a pairing process needs to be performed first, and after the pairing is completed, the connection is performed, so that one-to-one communication connection is established between the connected bluetooth device and the terminal device. The transmission of data and control commands between the bluetooth device and the terminal device can be carried out via the established bluetooth connection.
In the existing Bluetooth volume adjustment method, the volume of the Bluetooth equipment can be adjusted only by responding to the operation of adjusting the volume by a hardware adjustment module configured in the Bluetooth equipment, so that the cost, the volume and the power consumption of the Bluetooth equipment are improved. Therefore, in the method for adjusting the volume of the bluetooth device provided in this embodiment, the output volume of the bluetooth device is not adjusted by relying on the hardware adjusting module in the bluetooth device, but the output volume of the bluetooth device is adjusted by adjusting the gain of the audio data sent to the bluetooth device by the terminal device.
First, the terminal device needs to obtain a volume adjustment instruction for adjusting the volume of the bluetooth device connected to the terminal device through bluetooth, where the volume adjustment instruction may be input by a user in the terminal device, or input by the user in the bluetooth device connected to the terminal device, and is sent to the terminal device through bluetooth connection. And after the terminal equipment acquires the volume adjusting instruction, determining the Bluetooth volume value needing to be adjusted. The volume adjustment instruction includes, for example, an absolute value for adjusting the bluetooth volume, and if the bluetooth volume is 80%, or the bluetooth volume is 50 decibels, the terminal device will know that the bluetooth volume needs to be adjusted to 80% of the maximum output volume or to 50 decibels. For another example, the volume adjustment instruction includes a relative value for adjusting the bluetooth volume, and if the bluetooth volume is increased by 10%, or the bluetooth volume is increased by 5 db, the terminal device will know that the bluetooth volume needs to be adjusted to 110% of the current bluetooth volume, or the current bluetooth volume is increased by 5 db.
And step 102, adjusting the volume gain of the audio data to be sent to the Bluetooth equipment according to the Bluetooth volume value.
And after the terminal equipment acquires the Bluetooth volume value from the volume adjusting instruction, adjusting the volume gain of the audio data to be sent to the Bluetooth equipment. Because the bluetooth communication is a wireless communication connection, all the data sent to the bluetooth device by the terminal device through the bluetooth connection is data, and the audio to be played on the bluetooth device is also sent to the bluetooth device in the form of audio data.
In the adjustment of the audio output size, there are two concepts, one is volume and the other is gain. Wherein, the volume is the total level of the output signal at the output end, and the gain is the signal size before the audio is amplified, i.e. the input sensitivity of the audio signal is adjusted. The adjustment of the gain is performed at the input, i.e. the level of the audio signal to be output at the input is directly adjusted. The adjustment of the volume and the adjustment of the gain are different, and since the audio signal is transmitted from the input device to the output device and is emitted, in addition to the audio signal itself, noise such as system noise and environmental noise of the input device and the output device itself is also introduced, the adjustment of the output volume at the output end is actually a process of adjusting the volume of a composite signal synthesized by the audio signal and the noise at the same time. And the gain is adjusted at the input end, only the output level amplitude of the audio signal is adjusted, and after the adjusted audio signal is transmitted to the output equipment, the audio signal and various noises are synthesized and output.
For the Digital audio data in the embodiment of the present application, the input device is a terminal device, the audio data to be sent to the bluetooth device is a Digital audio signal, and after the audio data is sent to the bluetooth device through the bluetooth connection, a Digital-to-Analog Converter (DAC) in the bluetooth device converts the audio data into an Analog signal and outputs the Analog signal. Wherein the different gains of the audio signals correspond to the output levels of the analog audio signals after digital-to-analog conversion of the audio data. Therefore, the volume gain of the audio data to be sent to the Bluetooth device in the terminal device is adjusted, and the purpose of adjusting the output volume of the Bluetooth device can be achieved. That is, according to the bluetooth volume value, the output level amplitude of the audio data to be sent to the bluetooth device is adjusted, so as to adjust the volume gain of the audio data to be sent to the bluetooth device.
And 103, sending the audio data after the gain adjustment to the Bluetooth equipment.
After the gain of the audio data is adjusted, the audio data with the adjusted gain can be sent to the Bluetooth device. And after receiving the audio data after the gain adjustment through the Bluetooth connection, the Bluetooth device performs digital-to-analog conversion on the audio data to obtain an analog audio signal after the gain adjustment. The Bluetooth device plays the analog audio signal, which is equivalent to playing the audio signal after the volume is adjusted. However, by adopting the volume adjustment method for the bluetooth device provided by the embodiment of the application to adjust the volume of the output signal of the bluetooth device, the volume adjustment module on the bluetooth device is not needed, but the terminal device directly adjusts the gain of the audio data at the input end, so that the bluetooth device does not need to be configured with the volume adjustment module, the cost of the bluetooth device is saved, the power consumption of the bluetooth device is reduced, and the miniaturization design of the bluetooth device is facilitated.
According to the volume adjustment method for the Bluetooth equipment, the volume adjustment instruction for adjusting the volume of the Bluetooth equipment connected with the terminal equipment is acquired by the terminal equipment, the Bluetooth volume value is determined, then the volume gain of audio data to be sent to the Bluetooth equipment is adjusted according to the Bluetooth volume value, so that the processing for adjusting the volume of the Bluetooth equipment is completely completed in the terminal equipment, and therefore a volume adjustment module for adjusting the volume is not required to be configured in the Bluetooth equipment, the cost of the Bluetooth equipment is saved, the power consumption of the Bluetooth equipment is reduced, and the miniaturization design of the Bluetooth equipment is facilitated.
The existing bluetooth device and terminal device are generally configured with a bluetooth volume adjusting button or related functions, and a user can adjust the output volume of the bluetooth device through operation on the bluetooth device and also can adjust the output volume of the bluetooth device through operation on the terminal device. The two adjusting scenarios are used below to further explain the volume adjusting method of the bluetooth device shown in the embodiment shown in fig. 1.
Fig. 2 is a flowchart of a second embodiment of a method for adjusting the volume of a bluetooth device according to an embodiment of the present application, and as shown in fig. 2, the method for adjusting the volume of a bluetooth device according to the present embodiment includes:
step 201, obtaining a volume adjustment instruction which is input by a user operating on the terminal device and used for adjusting the volume of the connected bluetooth device, and determining the bluetooth volume value.
In the method for adjusting the volume of the bluetooth device provided in this embodiment, a user performs a volume adjustment operation on the terminal device to adjust the volume of the bluetooth device connected to the terminal device. The terminal device generally has a physical key for volume adjustment, such as a push key or a touch key, the volume adjustment key generally has two functions of volume up and volume down, and some terminal devices also have a mute key or a switch. The user can adjust the volume by pressing or touching a physical key for volume adjustment. When the terminal device establishes a bluetooth connection with the bluetooth device, the volume adjustment operation performed on the terminal device will correspond to adjusting the volume of the bluetooth device. The display interface of the terminal equipment can also display a volume adjustment option, a volume adjustment button or a volume adjustment progress bar and the like, and a user adjusts the volume through operation on the display interface. In addition, if the terminal device itself also has an audio output capability, the terminal device may further include at least two volume adjustment options, one of which is used to adjust the bluetooth volume of the bluetooth device connected to the terminal device, and the other is used to adjust the output volume of the terminal device itself. The user may simply choose to adjust the bluetooth volume of the bluetooth device to which the terminal device is connected.
In a word, after the user operates the terminal device, the terminal device may obtain a volume adjustment instruction for adjusting the volume of the bluetooth device connected to the terminal device through analysis of the user operation. The terminal device can determine the Bluetooth volume value corresponding to the volume adjusting instruction through analysis of user operation according to a preset rule. For example, the user presses the volume up key of the terminal device once, which means that the bluetooth volume is increased by 10%, and so on.
Step 202, according to the bluetooth volume value, adjusting the volume gain of the audio data to be sent to the bluetooth device.
This step is the same as step 102 and is not described here again.
Step 203, sending a volume adjustment notification to the bluetooth device, where the volume adjustment notification includes the bluetooth volume value of the audio data after the gain adjustment.
Since both the bluetooth device and the terminal device may have the volume adjustment capability, if the gain of the audio data is only adjusted in the terminal device, although the bluetooth device may finally output the audio data after the gain adjustment, the bluetooth volume value stored in the bluetooth device may still be the bluetooth volume value before the volume adjustment. If the user performs the volume adjustment operation on the bluetooth device again, the bluetooth volume may be adjusted based on the volume value before adjustment on the bluetooth device, which may cause a volume adjustment error and affect the user.
Therefore, after the terminal device adjusts the volume gain of the audio data to be sent to the bluetooth device, a volume adjustment notification may also be sent to the bluetooth device, where the volume adjustment notification includes the bluetooth volume value of the audio data after the gain adjustment. Then, after receiving the volume adjustment notification, the bluetooth device will know that the bluetooth volume is currently adjusted, and the bluetooth device will adjust the stored bluetooth volume value, so that the bluetooth volume values of the bluetooth device and the terminal device are kept consistent. Therefore, when the user adjusts the volume of the Bluetooth device again, the user can carry out correct adjustment no matter the user operates on the Bluetooth device or the terminal device.
It should be noted that this step is optional, and the terminal device does not have to send the volume adjustment notification to the bluetooth device.
And step 204, sending the audio data after the gain adjustment to the Bluetooth equipment.
This step is the same as step 103 and is not described here again.
The volume adjustment method for the bluetooth device provided by this embodiment obtains the volume information input by the user operating the terminal device, a volume adjustment command for adjusting the volume of the connected Bluetooth device, determining the Bluetooth volume value, adjusting the volume gain of the audio data to be sent to the Bluetooth device according to the Bluetooth volume value, and transmits a volume adjustment notification including a bluetooth volume value of the gain-adjusted audio data to the bluetooth device, the process of adjusting the volume of the Bluetooth device is completely finished in the terminal device, so that a volume adjusting module for adjusting the volume is not required to be configured in the Bluetooth device, therefore, the cost of the Bluetooth equipment is saved, the power consumption of the Bluetooth equipment is reduced, the miniaturization design of the Bluetooth equipment is facilitated, and the Bluetooth volume values in the terminal equipment and the Bluetooth equipment can be kept consistent.
Fig. 3 is a flowchart of a third embodiment of a method for adjusting the volume of a bluetooth device according to an embodiment of the present application, and as shown in fig. 3, the method for adjusting the volume of a bluetooth device according to the present embodiment includes:
In the method for adjusting the volume of the bluetooth device provided in this embodiment, a user performs a volume adjustment operation on the bluetooth device connected to the terminal device to adjust the volume of the bluetooth device. Bluetooth devices generally have physical keys for volume adjustment, such as push keys or touch keys, and volume adjustment keys generally have two functions of volume up and volume down. The user can adjust the volume by pressing or touching a physical key for volume adjustment. When the Bluetooth connection is established between the Bluetooth device and the terminal device, after the user performs volume adjustment operation on the Bluetooth device, the Bluetooth device generates a volume adjustment instruction, wherein the volume adjustment instruction comprises a Bluetooth volume value. The bluetooth device will send the volume adjustment instruction to the terminal device that has been connected through bluetooth.
After receiving the volume adjustment instruction, the terminal device can acquire the Bluetooth volume value therein.
This step is the same as step 102 and is not described here again.
In the embodiment shown in fig. 2, since the volume adjustment operation is performed in the terminal device, the terminal device may adjust the bluetooth volume value in the terminal device after acquiring the volume adjustment operation. However, in this embodiment, since the volume adjustment operation is performed in the bluetooth device, after the terminal device receives the volume adjustment instruction sent by the bluetooth device, optionally, the bluetooth volume value corresponding to the bluetooth device in the terminal device may also be adjusted to the bluetooth volume value of the audio data after the gain is adjusted. Therefore, the Bluetooth volume value in the terminal equipment and the Bluetooth equipment is ensured to be uniform.
The execution sequence of the step 302 and the step 303 is not divided in sequence.
And step 304, sending the audio data after the gain adjustment to the Bluetooth equipment.
This step is the same as step 103 and is not described here again.
In the volume adjustment method for the bluetooth device provided by this embodiment, the terminal device determines the bluetooth volume value by receiving the volume adjustment instruction sent by the bluetooth device, then adjusts the volume gain of the audio data to be sent to the bluetooth device according to the bluetooth volume value, and sends the volume adjustment notification including the bluetooth volume value of the audio data after the gain adjustment to the bluetooth device, so that the processing of performing volume adjustment on the bluetooth device is completely completed in the terminal device, and therefore, a volume adjustment module for performing volume adjustment does not need to be configured in the bluetooth device, thereby saving the cost of the bluetooth device, reducing the power consumption of the bluetooth device, facilitating the miniaturization design of the bluetooth device, and enabling the bluetooth volume values in the terminal device and the bluetooth device to be consistent.
Fig. 4 is a flowchart of a fourth embodiment of a method for adjusting the volume of a bluetooth device according to the embodiment of the present application, and as shown in fig. 4, the method for adjusting the volume of a bluetooth device according to the embodiment includes:
step 401, obtaining a bluetooth volume value determined according to a bluetooth volume adjustment instruction input by a user.
The volume adjustment method for the bluetooth device provided by the embodiment is applied to the bluetooth device connected with the terminal device. The terminal device is any terminal device capable of performing bluetooth connection with a bluetooth device, such as a mobile phone, a tablet computer, a music player, and the like. The bluetooth device connected with the terminal device is any device which can be connected with the terminal device through bluetooth and has an audio playing function, such as a bluetooth headset, a bluetooth sound box, a vehicle-mounted sound box and the like.
Before playing the audio on the terminal device by using the bluetooth device, the bluetooth device and the terminal device need to be connected through bluetooth first. The specific mode of connecting the bluetooth device with the terminal device can adopt any one of the current modes, and is not repeated in the application. However, before the bluetooth device is connected with the terminal device, a pairing process needs to be performed first, and after the pairing is completed, the connection is performed, so that one-to-one communication connection is established between the connected bluetooth device and the terminal device. The transmission of data and control commands between the bluetooth device and the terminal device can be carried out via the established bluetooth connection.
In the existing Bluetooth volume adjustment method, the volume of the Bluetooth equipment can be adjusted only by responding to the operation of adjusting the volume by a hardware adjustment module configured in the Bluetooth equipment, so that the cost, the volume and the power consumption of the Bluetooth equipment are improved. Therefore, in the method for adjusting the volume of the bluetooth device provided in this embodiment, the output volume of the bluetooth device is not adjusted by relying on the hardware adjusting module in the bluetooth device, but the output volume of the bluetooth device is adjusted by adjusting the gain of the audio data sent to the bluetooth device by the terminal device.
The bluetooth volume adjustment instruction for adjusting the volume of the bluetooth device may be performed by the user on the terminal device or may be performed by the user on the bluetooth device. The bluetooth volume adjustment instruction is acquired by the terminal device regardless of where the user performs the operation of adjusting the volume of the bluetooth device. And then the terminal equipment adjusts the volume gain of the audio data to be sent to the Bluetooth equipment according to the Bluetooth volume value in the Bluetooth volume adjusting instruction. The specific method for adjusting the volume gain of the audio data to be sent to the bluetooth device by the terminal device is the same as that in the embodiment shown in fig. 1, and is not described herein again.
After the terminal equipment adjusts the Bluetooth volume value, the Bluetooth volume value is sent to the Bluetooth equipment, so that the Bluetooth equipment can know the adjustment of the Bluetooth volume.
And after the volume gain of the audio data to be sent to the Bluetooth equipment is adjusted, the terminal equipment sends the audio data after the gain adjustment to the Bluetooth equipment. And the Bluetooth device receives the audio data which is sent by the terminal device and subjected to the volume gain adjustment through Bluetooth connection. The audio data is received in the form of a digital signal.
In step 403, the audio data is played.
And after receiving the audio data after the gain adjustment through the Bluetooth connection, the Bluetooth device performs digital-to-analog conversion on the audio data to obtain an analog audio signal after the gain adjustment. The Bluetooth device plays the analog audio signal, which is equivalent to playing the audio signal after the volume is adjusted. However, by adopting the volume adjustment method for the bluetooth device provided by the embodiment of the application to adjust the volume of the output signal of the bluetooth device, the volume adjustment module on the bluetooth device is not needed, but the terminal device directly adjusts the gain of the audio data at the input end, so that the bluetooth device does not need to be configured with the volume adjustment module, the cost of the bluetooth device is saved, the power consumption of the bluetooth device is reduced, and the miniaturization design of the bluetooth device is facilitated.
According to the volume adjustment method for the Bluetooth equipment, the audio data which are sent by the terminal equipment connected with the Bluetooth equipment and subjected to volume gain adjustment are received and played, so that the processing of volume adjustment on the Bluetooth equipment is completely finished in the terminal equipment, and therefore a volume adjustment module for volume adjustment does not need to be configured in the Bluetooth equipment, the cost of the Bluetooth equipment is saved, the power consumption of the Bluetooth equipment is reduced, and the miniaturization design of the Bluetooth equipment is facilitated.
The existing bluetooth device and terminal device are generally configured with a bluetooth volume adjusting button or related functions, and a user can adjust the output volume of the bluetooth device through operation on the bluetooth device and also can adjust the output volume of the bluetooth device through operation on the terminal device. The two adjusting scenarios are used to further explain the volume adjusting method of the bluetooth device shown in the embodiment shown in fig. 4.
Fig. 5 is a flowchart of a fifth embodiment of a method for adjusting the volume of a bluetooth device according to an embodiment of the present application, and as shown in fig. 5, the method for adjusting the volume of a bluetooth device according to the present embodiment includes:
step 501, receiving a volume adjustment notification sent by a terminal device, where the volume adjustment notification includes a bluetooth volume value.

Therefore, after the terminal device adjusts the volume gain of the audio data to be sent to the bluetooth device, a volume adjustment notification may also be sent to the bluetooth device, where the volume adjustment notification includes the bluetooth volume value of the audio data after the gain adjustment. The Bluetooth device can acquire the Bluetooth volume value after receiving the volume adjustment notification.
Step 502, adjust the bluetooth volume value in the bluetooth device to the bluetooth volume value in the volume adjustment notification.
After the Bluetooth device receives the volume adjustment notification, the Bluetooth device can know that the Bluetooth volume is currently adjusted, and the Bluetooth device can adjust the Bluetooth volume value in the Bluetooth device, so that the Bluetooth volume values of the Bluetooth device and the terminal device are kept consistent. Therefore, when the user adjusts the volume of the Bluetooth device again, the user can carry out correct adjustment no matter the user operates on the Bluetooth device or the terminal device.
Step 503 and step 504 are the same as step 402 and step 403, and are not described here again.
In the volume adjustment method for the bluetooth device provided by this embodiment, the audio data after the volume gain adjustment sent by the terminal device connected to the bluetooth device is received and played, and the volume adjustment notification sent by the terminal device is received to adjust the bluetooth volume value of the bluetooth device, so that the processing of volume adjustment on the bluetooth device is completely completed in the terminal device, and therefore, a volume adjustment module for volume adjustment does not need to be configured in the bluetooth device, thereby saving the cost of the bluetooth device, reducing the power consumption of the bluetooth device, facilitating the miniaturization design of the bluetooth device, and enabling the bluetooth volume values in the terminal device and the bluetooth device to be consistent.
