Referring to fig. 1, a schematic diagram of an application environment of an embodiment of a method for dynamically adjusting a speaker frequency response of an earphone according to the present application is shown, wherein the method for dynamically adjusting the speaker frequency response of the earphone is applied to an earphone, and the earphone is communicatively connected to an electronic device capable of playing audio, and the earphone 10 may be a stereo earphone (such as a headphone, an earplug-type stereo earphone) or a TWS (True Wireless Stereo, real wireless stereo) earphone.
The stereo earphone has the difference between left and right channels, and cannot be used interchangeably, otherwise, the fidelity of a sound source and the resolution of the frequency of the sound source are directly affected.
The TWS technology is developed based on the Bluetooth chip technology, and the working principle of the TWS technology is that a mobile phone is connected with a main earphone, and then the main earphone is connected with an auxiliary earphone in a wireless mode, so that real Bluetooth left and right channel wireless separation is realized.
As shown in fig. 1, when the earphone is a stereo earphone, the stereo earphone is provided with a control chip, the control chip realizes a left channel and a right channel, the left channel is connected with a left loudspeaker, the right channel is connected with a right loudspeaker, and the control chip controls the left loudspeaker and the right loudspeaker to output audio signals. The stereo earphone is a wired earphone or a Bluetooth earphone, when the stereo earphone is the wired earphone, a 3.5mm plug of the stereo earphone is inserted into an earphone jack of the electronic equipment, so that connection between the wired earphone and the electronic equipment can be realized, if the electronic equipment does not have the 3.5mm earphone jack, an adapter is needed, the 3.5mm plug of the earphone is inserted into the earphone jack of the adapter, and then the other end of the adapter is inserted into a charging port of the electronic equipment. When the stereo earphone is a Bluetooth earphone, the Bluetooth earphone is connected with the electronic equipment in a Bluetooth mode, and audio playing of the electronic equipment by the Bluetooth earphone can be achieved.
As shown in fig. 2, when the earphone is a TWS earphone, the two control chips are needed for wireless separation of left and right channels of the bluetooth, one control chip realizes a left channel, the other control chip realizes a right channel, correspondingly, the left channel is connected with a left horn, the right channel is connected with a right horn, one control chip controls the left horn to output an audio signal of the left channel, and the other control chip controls the right horn to output an audio signal of the right channel. The TWS earphone is a Bluetooth earphone, when the TWS earphone is connected with the electronic equipment, the Bluetooth function is required to be opened on the electronic equipment, the earphone is set to be searched, and then the earphone is searched and connected with the electronic equipment.
In the production process of the stereo earphone and the TWS earphone, the difference of the frequency response of the horns of the left ear and the right ear of the individual earphone can be caused due to the error of materials, the consistency check can be carried out before the earphone leaves the factory, the frequency response curve can be obtained through frequency sweeping of acoustic equipment, and the difference of the frequency response of the left horn and the right horn can be known through the frequency response curve. In the actual use process of the earphone, the user has different frequency response requirements on the left and right horns due to different sensitivity of the left and right ears of the user.
In order to solve the above-mentioned problems, an embodiment of the present application provides a method for dynamically adjusting the speaker frequency response of an earphone applied to the application environment, which can be executed by the controller 101 of the earphone 10, referring to fig. 3, and the method includes the following steps S301 to S303.
S301: the total digital gain is fixed upon detecting the frequency response adjustment requirements of the left and right speakers of the headset.
The frequency response adjustment requirement refers to the requirement that the frequency response of the left loudspeaker and the right loudspeaker is inconsistent, or when the user senses that the frequency response of the left loudspeaker and the right loudspeaker is inconsistent, the user needs to adjust the frequency response of the left loudspeaker and the right loudspeaker.
The earphone is connected with the electronic device, and APP (Application) is installed on the electronic device in a downloading mode. When the user feels that the frequency response of the left loudspeaker and the right loudspeaker of the earphone are inconsistent, or the user needs to adjust the frequency response difference of the left loudspeaker and the right loudspeaker in a personalized way, the user can enter the loudspeaker frequency response adjusting state of the earphone through the APP, the earphone detects the frequency response adjusting requirement, and the total digital gain is fixed.
Gain is a very common measurement for amplifiers. Gain is the ratio between the output level and the input level of a device such as a headset. As a ratio, gain is typically expressed in decibels (dB) as a unit of measure, but may also be expressed in percent. Volume (or loudness) is a subjective concept about the perception of sound by a listener. There are no volume units, only percentages or no reference numbers. Gain is the ratio of the input signal of the amplifier to the output signal of the amplifier, and is most of the time greater than 1, and sometimes less than 1.
Gain is used to enhance the signal input into the speaker circuit, and in general, the process of adjusting the gain parameter is to adjust the intensity of the input signal in the front stage area, i.e., gain control is to the input end of the device.
As shown in fig. 4, fig. 4 is a schematic block diagram of the chip side of the headset.
As can be seen in fig. 4, the gain of the digital-to-analog converter DAC is divided into an analog gain and a digital gain at the chip end of the earphone. The analog gain is only one stage of total analog gain, the digital gain is two stages, and the first stage is a left channel digital gain and a right channel digital gain; the second stage is the total digital gain of the left and right channels.
In some of these embodiments, the headphones are stereo headphones, the fixed total digital gain comprising:

Specifically, when the earphone is a stereo earphone, since the stereo earphone has only one control chip to control the left channel and the right channel, the left speaker and the right speaker are correspondingly connected respectively, and when the earphone enters the frequency response adjusting state, the control chip of the stereo earphone enables the left channel digital gain and the right channel digital gain, so that the left channel digital gain and the right channel digital gain are in an adjustable state, and meanwhile, the two-level digital gain, that is, the total digital gain of the left channel and the right channel is fixed, and the total analog gain is fixed.
The enabling refers to allowing a certain pin (pin), chip or module of the electronic device to start a certain preset function and enter a preset state. Enabling the left channel digital gain and enabling the right channel digital gain can be achieved by setting corresponding registers in the control chip of the stereo headphones.
In some of these embodiments, when the headset is a TWS headset, the fixed total digital gain comprises:
and turning off the left channel digital gain enable and turning off the right channel digital gain enable to place the left channel digital gain and the right channel digital gain in an unadjustable state to fix the left channel digital gain and the right channel digital gain.
Specifically, when the earphone is a TWS earphone, since the TWS earphone adopts two control chips, and one control chip controls one channel, then, when the total digital gain is fixed, the left channel digital gain is actually fixed, and the right channel digital gain is fixed, so that the left channel digital gain is required to be turned off, and the right channel digital gain is required to be turned off, that is, the two control chips respectively control the respective channel digital gain to be turned off, so that the first-stage digital gain is turned off, and the left channel digital gain and the right channel digital gain are in an unadjustable state, thereby realizing the fixed left channel digital gain and the right channel digital gain.
S502: and setting the gains of the left and right channels according to the total digital gain so that the difference between the frequency response of the left loudspeaker and the frequency response of the right loudspeaker meets the frequency response curve requirement.
The frequency response curve is that before the earphone leaves the factory, consistency check can be made, and the frequency response curve can be obtained by utilizing the frequency sweep of acoustic equipment, and the frequency response curve represents the frequency response of the left loudspeaker and the frequency response of the right loudspeaker, so that the frequency response difference of the left loudspeaker and the right loudspeaker is determined.
Since the total digital gain is fixed, when the earphone is a stereo earphone, in some embodiments, the setting the gain of the left and right channels may include:
and setting a left channel digital gain and a right channel digital gain according to the fixed total digital gain, so that the difference between the frequency response of the left loudspeaker and the frequency response of the right loudspeaker meets the frequency response curve requirement.
Specifically, when the earphone is a stereo earphone, the total digital gain is the total digital gain of the left and right channels, the left channel digital gain adjustment interface and the right channel digital gain adjustment interface are displayed in the frequency response adjustment state, a user can set the left channel digital gain and the right channel digital gain which the user wants through the APP of the electronic equipment, the earphone sets the gain according to the left channel digital gain and the right channel digital gain set by the user, and the difference between the frequency response of the left loudspeaker and the frequency response of the right loudspeaker accords with the frequency response curve requirement through the gain setting, so that the frequency response difference requirement of the user on the left loudspeaker and the right loudspeaker is met.
It can be understood that the APP sets SPP wireless transmission technology, which is an existing bluetooth technology, is a wireless communication serial port for transmitting data. The user can operate through the APP of the electronic device to set the left channel digital gain and the right channel digital gain.
In some embodiments, when the earphone is a TWS earphone, the setting the gain of the left and right channels includes:
according to the fixed left channel digital gain, setting the analog gain of the left earphone, and according to the fixed right channel digital gain, setting the analog gain of the right earphone, so that the difference between the frequency response of the left loudspeaker and the frequency response of the right loudspeaker meets the frequency response curve requirement.
Specifically, when the headphones are TWS headphones, since the left channel digital gain and the right channel digital gain are fixed, the analog gain of the left headphone can be set according to the fixed left channel digital gain, and the analog gain of the right headphone can be set according to the fixed right channel digital gain.
Correspondingly, the user sets the analog gain of the left earphone and the analog gain of the right earphone on the APP of the electronic equipment, so that the difference between the frequency response of the left loudspeaker and the frequency response of the right loudspeaker accords with the frequency response curve requirement, and the frequency response difference requirement of the user on the left loudspeaker and the right loudspeaker is met.
S503: and when receiving a volume adjustment instruction, adjusting the total digital gain based on the frequency response curve demand.
Specifically, after the frequency response curve demand is determined, the user can exit the frequency response adjustment state on the APP of the electronic device and can enter the volume adjustment state of the earphone, when the user operates the volume adjustment of the earphone, the earphone generates a volume adjustment instruction, and the earphone adjusts the total digital gain based on the frequency response curve demand of the user.
In some embodiments, when the headphones are stereo headphones, the adjusting the total digital gain comprises:
the total analog gain is adjusted, or the total analog gain is adjusted.
Specifically, when the earphone is a stereo earphone, the user only needs to adjust the volume, and the earphone adjusts the total digital gain or the total analog gain, so that the change of the frequency response amplitude difference between the left loudspeaker and the right loudspeaker of the earphone is not affected.
In some embodiments, when the headset is a TWS headset, the adjusting the total digital gain includes:
and adjusting the total digital gain of the left earphone and the total digital gain of the right earphone.
When the earphone is a TWS earphone, the left earphone is controlled by one control chip, the right earphone is controlled by the other control chip, and when a user needs to adjust the volume, the one control chip adjusts the total digital gain of the left earphone, and the other control chip adjusts the total digital gain of the right earphone, so that the change of the frequency response amplitude difference between the left loudspeaker and the right loudspeaker of the earphone is not influenced.
In some of these embodiments, the method further comprises:
and controlling the left loudspeaker to output first audio synthesized by the left channel digital gain, the total digital gain and the total analog gain, and controlling the right loudspeaker to output second audio synthesized by the right channel digital gain, the total digital gain and the total analog gain.
Specifically, whether it be a stereo headphone or a TWS headphone, when the user adjusts the headphone volume, the headphone controls the left speaker to output first audio synthesized by the left channel digital gain, the total digital gain, and the total analog gain, and controls the right speaker to output second audio synthesized by the right channel digital gain, the total digital gain, and the total analog gain. The playing function of the left loudspeaker and the right loudspeaker on the audio frequency is realized.
According to the embodiment of the application, when a user feels that the frequency response of the left loudspeaker and the right loudspeaker of the earphone are inconsistent, or the frequency response of the left loudspeaker and the right loudspeaker are different due to the problem of the material of the earphone, the user can perform loudspeaker frequency response adjustment on the earphone.
