Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
A plurality of bluetooth devices, a first bluetooth device of one of the plurality of bluetooth devices configured to: in response to detecting a first adjustment signal of the volume of the first Bluetooth device when the Bluetooth device is in cooperative work with other Bluetooth devices in the plurality of Bluetooth devices based on the homologous audio, generating a first adjustment event based on the first adjustment signal, acquiring a first adjustment value based on the first adjustment signal, and adjusting the volume of the first Bluetooth device based on the first adjustment value.
For example, as shown in fig. 1, the plurality of bluetooth devices include: bluetooth device 1, bluetooth devices 2 and … …, and Bluetooth device n, wherein the total number of Bluetooth devices is n; n bluetooth devices cooperate based on homologous audio, i.e., the same audio is being played or listened to simultaneously in n bluetooth devices; when a first bluetooth device, such as a mobile phone, characterized by the bluetooth device 1, performs a volume adjustment, the bluetooth device 1 generates a first adjustment signal, which not only performs a volume adjustment to the bluetooth device 1, but also generates a first adjustment event and a first adjustment value.
And the car machine is in Bluetooth communication connection with the plurality of Bluetooth devices respectively and comprises a monitoring service module and an adjusting service module.
The monitoring service module is configured to: and receiving a first adjustment value transmitted by the first Bluetooth device in response to the first adjustment event transmitted by the first Bluetooth device.
In the embodiment of the application, all events are monitored through a monitoring service module. For example, continuing the above example, the listening service module listens for a first throttling event (such as an AT command sent by the handset to the car set) from the bluetooth protocol stack.
The regulation service module is configured to: responding to the first adjustment value, and respectively generating respective volume adjustment instructions of the other Bluetooth devices based on the first adjustment value and respective preset first frequency response parameter values of the other Bluetooth devices; and transmitting the respective volume adjustment instructions of the other Bluetooth devices to the corresponding Bluetooth devices respectively.
In this embodiment of the present application, a preset first frequency response parameter value is provided between each other bluetooth device and a first bluetooth device, and the preset first frequency response parameter value is applied to an equalization processor (EQ) algorithm. The method comprises the steps of storing preset first frequency response parameter values of a plurality of Bluetooth devices in a vehicle.
Frequency response curve decomposition: "frequency" refers to frequency, which is the same tone in an acoustic representation; a "sound" can then be seen as a response of the speaker system (both mechanical and electrical) to the intermediate frequency conversion of an input electrical signal into acoustic energy. And this response is received by the microphone and is presented as a dB SPL logarithmic value after calculation by the test instrument. When a plurality of response values of the frequency are connected together, a peak-to-valley curve is formed, and the curve is called a frequency characteristic response curve, which is called a frequency response curve for short.
The frequency response curve of a loudspeaker box or sound system is flat, in the sense that it tells the user which frequency bands are neither emphasized (boosted) nor deficit (attenuated) for the input signal, under certain conditions, the expressive power (i.e. the amount of gain for the sound in the different frequency bands) is approximately the same in each frequency band. How much you were originally, i give you how much. And the sound box or the system woolen with uneven curves can be inconsistent in gain quantity on certain frequency bands, and the sound box or the system woolen with uneven curves is too strong (the position with prominent gain quantity on the curves) or too weak (the position with sunken gain quantity on the curves) for certain frequency bands. Say, the curve of a certain sound box near 80 hz is more prominent, so that the sound box has too strong expressive force for the frequency band near 80 hz, and if music is played, the sound of the bass can feel heavy. Or the curve of a certain sound box is concave near 1000 Hz, which means that the sound box has weak expressive force on the frequency band near 1000 Hz, the sound pressure output on the frequency band near 1000 Hz in the input signal is reduced, and the output sound is not the same as the original sound.
For example, a balanced pleasing sound should be:
below 150Hz (bass) should be plump, soft and elastic;
150Hz-500Hz (medium bass) should be a powerful and turbid;
500Hz-5KHz (medium-high frequency) should be bright and thorough without being hard;
above 5KHz (high pitch) should be slim, round and not sharp.
Therefore, the sound quality of a sound box is poor, the sound quality is mainly suitable for the frequency response curve, the power amplifier of the vehicle and the Bluetooth headset belong to two sets of audio output equipment, the prior proposal has no correlation between the volume and the frequency response curve, and the percentage cannot represent the actual loudness of a loudspeaker, thus the invention establishes two sets of frequency response curves

Considering the distance between a listener and a loudspeaker in a practical application scene, in the debugging process, the external position of the automobile body is about 1 meter away from the artificial ear, and the distance between the earphone and the artificial ear is about 1 cm.
Along with the change of the playing progress bar, the original data sent into the EQ algorithm is changed, after the conversion from the time domain to the frequency domain, the frequency point is changed, and the corresponding loudness is actually changed along with the real-time data, so that the actual effect is that the loudness of the car player and the Bluetooth headset is slightly different along with the change of the original data, but the original data is more in line with the frequency response curve, and the user experience is more comfortable.
Specifically, the method for obtaining the preset frequency response parameter value between the vehicle speaker and the Bluetooth device comprises the following steps:
1. in the mute room, the car machine loudspeaker is arranged at a distance of about 1 meter from the artificial ear, and the Bluetooth earphone is arranged at a distance of about 1 cm from the artificial ear;
2. the car machine loudspeaker and the Bluetooth earphone play the sweep frequency files of 1 HZ-10 KHZ respectively under the same volume value, and the same artificial ear is used for recording audio in a time-sharing way to ensure the consistency of the effect;
3. according to the difference of the loudness of the midrange region of the frequency response curve of the vehicle speaker and the Bluetooth headset, multiplying the whole with a software gain value to make the midrange loudness of the vehicle speaker and the Bluetooth headset consistent;
4. Respectively adjusting parameter values of EQ algorithm corresponding to the vehicle speaker and the Bluetooth headset, so that frequency responses of the vehicle speaker and the Bluetooth headset are consistent at the same volume;
5. the adjusted parameter value of the EQ algorithm is stored into a memory as a preset frequency response parameter value of the Bluetooth device, and when the vehicle speaker and the Bluetooth headset are cooperatively adjusted to output, the adjusting value of the vehicle speaker and the preset frequency response parameter value of the Bluetooth device are utilized to obtain the adjusting value of the Bluetooth device through the EQ algorithm; therefore, the loudness of the artificial ear is consistent with that of the audio sent by the speaker of the final car machine and the Bluetooth headset.
In order to ensure the consistency of loudness between every two bluetooth devices connected by bluetooth, the preset first frequency response parameter value of each bluetooth device or the preset second frequency response parameter value of the vehicle player module is obtained by the method.
