Obviously, the described embodiments are only It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

Furthermore, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes unlisted steps or units, or optionally also includes For other steps or units inherent to these processes, methods, products or devices.

Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor a separate or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

In order to better understand the solutions of the embodiments of the present application, related terms and concepts that may be involved in the embodiments of the present application are first introduced below.

Resonant frequency refers to the frequency corresponding to the point where the vibration plate vibrates most strongly when the speaker starts to vibrate from the low range. When measuring the impedance characteristics of the speaker unit, the frequency corresponding to the first time the impedance value on the impedance curve reaches the maximum value is called The resonant frequency or resonant frequency of the loudspeaker, referred to as F0. The amplitude of the vibration system of the loudspeaker is the largest at the resonant frequency, that is, the diaphragm near the resonant frequency has a preset diaphragm displacement (Maximum excursion of speaker diaphragm, Xmax) under the same voltage.

The resonant frequency will be affected by factors such as voltage, temperature, air pressure, etc. As shown in FIG. 1A , FIG. 1A is a schematic diagram of the corresponding relationship between voltage and resonant frequency provided by an embodiment of the application. It can be seen that as the output power of the speaker decreases, the voltage decreases. is small, the resonant frequency gradually increases; as shown in FIG. 1B , FIG. 1B is a schematic diagram of the corresponding relationship between temperature and resonant frequency provided by the embodiment of the application, it can be seen that as the temperature increases, the resonant frequency gradually decreases; As shown in 1C, FIG. 1C is a schematic diagram of the corresponding relationship between air pressure and resonant frequency provided by an embodiment of the present application. It can be seen that, under the same voltage, the resonant frequency under low air pressure is lower than the resonant frequency under high air pressure. To sum up, it can be seen that the resonant frequency is inversely proportional to the voltage, the resonant frequency is inversely proportional to the temperature, and the resonant frequency is proportional to the air pressure.

When the resonant frequency increases and the other factors remain unchanged, the diaphragm displacement of the speaker will become smaller, so the diaphragm displacement will not exceed the preset diaphragm displacement when the speaker is working normally; when the resonant frequency decreases and other factors remain unchanged, The diaphragm displacement of the speaker will become larger, and at this time, it may exceed the preset diaphragm displacement. Moreover, the reduction of the resonant frequency caused by the low pressure state is often far greater than the reduction of the resonant frequency caused by the temperature increase.

It can be seen that the temperature and air pressure in the external environment will affect the resonant frequency of the speaker during operation. It is often difficult to determine which factor causes the change of the resonant frequency. The operating amplitude of the existing speaker is generally about 80% of the preset diaphragm displacement. , which greatly loses the performance of the speaker.

In order to solve the above problems, the embodiment of the present application provides a speaker parameter configuration method and a related device, which can confirm the air pressure state according to the change of the resonant frequency of the speaker after eliminating the interference of the environmental temperature factor, and further configure the appropriate audio frequency according to the air pressure state. parameters, increase speaker performance utilization, suitable for a variety of environments, saving hardware costs.

A method for configuring loudspeaker parameters in an embodiment of the present application will be described below with reference to FIG. 2 . FIG. 2 is a schematic flowchart of a method for configuring loudspeaker parameters provided by an embodiment of the present application, applied to an electronic device, and specifically includes the following steps:

Step 201: Detect the actual resonant frequency of the speaker of the electronic device and the ambient temperature of the space where the electronic device is located.

The detection of the current actual resonance frequency of the speaker can be performed by a high-speed resonant frequency detector or by a built-in measurement algorithm, which is the prior art, and will not be repeated here. The ambient temperature of the space where the electronic device is located may be acquired through a temperature sensor.

Step 202 , query a preset set of mapping relationships to determine the reference resonance frequency corresponding to the ambient temperature.

The set of mapping relationships includes a correspondence relationship between the ambient temperature and the resonant frequency of the loudspeaker measured in advance under a preset air pressure condition, and the preset air pressure condition may represent a range between 0.9*standard atmospheric pressure and 1.1*standard atmospheric pressure. In the range of 0.9*standard atmospheric pressure to 1.1*standard atmospheric pressure, the relationship between different ambient temperature and resonance frequency is measured to determine the above-mentioned set of mapping relationships. In this way, the preset mapping relationship set can be directly called to find the reference resonance frequency corresponding to the current ambient temperature, where the reference resonance frequency is the resonance frequency corresponding to the ambient temperature under normal pressure.

By querying the preset mapping relationship set to determine the reference resonance frequency corresponding to the ambient temperature, the influence of the ambient temperature on the resonance frequency of the loudspeaker can be excluded. Accuracy of barometric state.

Step 203: Configure target audio parameters according to the actual resonant frequency and the reference resonant frequency, where the target audio parameters are used to make the diaphragm displacement of the speaker not exceed a preset diaphragm displacement.

Wherein, the above-mentioned target audio frequency parameter is used to make the diaphragm displacement of the loudspeaker not exceed the preset diaphragm displacement, the above-mentioned actual resonance frequency can be compared with the above-mentioned reference resonance frequency, and the magnitude relationship between the actual resonance frequency and the reference resonance frequency can be determined. , when the actual resonant frequency is greater than or equal to the reference resonant frequency, it can be determined that the actual air pressure is greater than or equal to the preset air pressure; when the actual resonant frequency is less than the reference resonant frequency, it can be determined The actual air pressure is less than the preset air pressure.

In a possible embodiment, when the actual resonant frequency is less than the above-mentioned reference resonant frequency, the difference between the actual resonant frequency and the reference resonant frequency can be obtained, and when the difference is less than or equal to a preset threshold, the actual air pressure at this time can be determined It is only slightly reduced. When the speaker is working normally, the diaphragm displacement will not exceed the preset diaphragm displacement; when the difference is greater than the preset threshold, it can be determined that the actual air pressure at this time is greatly reduced. When the speaker works in a high volume scene, the diaphragm will Exceeding the maximum displacement of the diaphragm, causing the speaker to work abnormally. The above-mentioned preset threshold can be set through experimental data, and can be adjusted according to the material and size of the diaphragm of the speaker, which is not specifically limited here.

It can be seen that since the resonant frequency of the speaker is affected by the ambient temperature and air pressure, after eliminating the interference of the ambient temperature, the actual air pressure and the actual air pressure of the space where the electronic device is located can be determined according to the actual resonant frequency and the reference resonant frequency. The magnitude relationship between the preset air pressures can be obtained without an air pressure sensor, thereby reducing the hardware cost.

In a possible embodiment, when the actual air pressure is greater than or equal to the preset air pressure, the diaphragm displacement of the speaker will become smaller under the same voltage condition, so the diaphragm displacement must not exceed the preset diaphragm displacement at this time. Configure preset audio parameters as target audio parameters. Specifically, the above-mentioned preset audio parameters are used to establish a reference voltage protection model, and the reference voltage protection model is suitable for a normal temperature and normal pressure environment. For example, if the reference resonant frequency is 500Hz, the diaphragm displacement corresponding to each 1V voltage at this time is 0.1mm, and the preset diaphragm displacement at this time is 0.5mm, then the reference voltage protection model can limit the output voltage within 5V to avoid the diaphragm displacement exceeding the preset diaphragm displacement of 0.5mm.

In a possible embodiment, when the actual air pressure is less than the preset air pressure, under the same voltage condition, the diaphragm displacement of the speaker will increase, and there is a risk of exceeding the preset diaphragm displacement. The corresponding relationship between the air pressure measured under the preset temperature condition and the resonant frequency of the speaker determines the target audio parameters corresponding to the actual air pressure for configuration, and the target audio parameters at this time can be used for the target voltage protection model. The voltage protection model can prevent the diaphragm displacement from exceeding the preset diaphragm displacement by automatically attenuating the overall link gain, and can also prevent the diaphragm displacement from exceeding the preset diaphragm displacement by attenuating large audio signals in the low frequency part. In particular, this goal The voltage protection model may also be a voltage protection model only applicable to a low pressure environment, which will not be repeated here.

Further, when the actual air pressure is less than the preset air pressure, the difference between the actual air pressure and the preset air pressure can be obtained, and when the difference between the actual air pressure and the preset air pressure is less than or equal to the preset threshold, it can be determined. At this time, the reduction of the actual resonant frequency is very small, and the diaphragm displacement of the speaker will not exceed the preset diaphragm displacement, so the above reference voltage protection model can still be used at this time; between the above actual air pressure and the above preset air pressure When the difference is greater than the preset threshold, the target voltage protection model needs to be called at this time to prevent the diaphragm displacement of the speaker from exceeding the preset diaphragm displacement. The above-mentioned preset threshold may be preset according to the preset diaphragm displacement corresponding to the actual resonance frequency. In this way, it can be ensured that the diaphragm displacement of the loudspeaker does not exceed the preset diaphragm displacement without wasting the performance of the loudspeaker.

It should be noted that when the actual air pressure is less than the preset air pressure, the target voltage protection model can be directly called, which can greatly improve the reliability of the speaker diaphragm displacement not exceeding the preset diaphragm displacement, but may waste some speaker performance.

Through the above method, first, the actual resonant frequency of the speaker of the electronic device and the ambient temperature of the space where the electronic device is located are detected; then, a preset set of mapping relationships is queried to determine the reference resonant frequency corresponding to the ambient temperature , the set of mapping relationships includes the corresponding relationship between the ambient temperature and the resonant frequency of the loudspeaker measured in advance under a preset air pressure condition; finally, the target audio parameters are configured according to the actual resonant frequency and the reference resonant frequency, Wherein, the above-mentioned target audio parameters are used to make the diaphragm displacement of the speaker not exceed the preset diaphragm displacement. After excluding the interference of ambient temperature factors, the ambient air pressure change can be simulated according to the change of the resonant frequency of the loudspeaker, and then appropriate audio parameters can be configured to increase the performance utilization of the loudspeaker, which is suitable for a variety of environments and saves hardware costs.

Another speaker parameter configuration method in the embodiment of the present application will be described below with reference to FIG. 3 . FIG. 3 is another speaker parameter configuration method provided by the embodiment of the present application, applied to an electronic device, and specifically includes the following steps:

Step 301 , the resonant frequency of the loudspeaker under preset air pressure conditions and different temperatures is detected by the control variable method to determine a preset mapping relationship set.

Wherein, the above-mentioned preset mapping relationship set may include the corresponding relationship between the ambient temperature measured in advance under the preset air pressure condition and the resonant frequency of the speaker.

Step 302: Detect the actual resonant frequency of the speaker of the electronic device and the ambient temperature of the space where the electronic device is located.

Step 303 , query a preset set of mapping relationships to determine the reference resonance frequency corresponding to the ambient temperature.

Step 304, judging whether the actual resonant frequency is less than the reference resonant frequency.

Wherein, if the above-mentioned actual resonance frequency is greater than or equal to the above-mentioned reference resonance frequency, step 305 is executed; if the above-mentioned actual resonance frequency is less than the above-mentioned reference resonance frequency, step 306 is executed.

Step 305, calling preset audio parameters as target audio parameters for configuration.

The above preset audio parameters can be used to construct a reference voltage protection model under normal temperature and normal pressure.

Step 306: Determine whether the difference between the actual resonant frequency and the reference resonant frequency is greater than a preset threshold.

Wherein, if the difference between the actual resonance frequency and the reference resonance frequency is less than or equal to the preset threshold, step 305 is executed; the difference between the actual resonance frequency and the reference resonance frequency is greater than the preset threshold, and step 307 is executed .

Step 307 , query the correspondence between the air pressure measured in advance under a preset temperature condition and the resonant frequency of the speaker to determine target audio parameters corresponding to the actual air pressure for configuration.

Step 308, detecting the audio playing state.

The playback state of the audio can be determined by detecting whether the audio process is closed. When the audio process is closed, it is in the state of audio stop playing, and when the audio process is running, it is in the state of audio playing.

Step 309, when the audio playing state is stop playing, adjust the target audio parameter to the preset audio parameter.

In this way, it can be avoided that the target audio parameters are continuously used when the working environment returns to normal, resulting in too low speaker sound. At the same time, real-time ambient temperature detection can be continued.

Step 310, when the audio playing state is playing, continue to call the target voltage protection model corresponding to the target audio parameter.

For the steps not described in detail above, reference may be made to some or all of the steps of the method described in FIG. 2 , and details are not described herein again.

In order to facilitate understanding, an example is given below. The diaphragm displacement of the loudspeaker under normal temperature and pressure is set to 0.43mm, and the preset diaphragm displacement at this time is 0.45mm. The diaphragm displacement will gain 0.1mm. At this time, the diaphragm displacement can be reduced by about 0.1mm by configuring the target audio parameters to attenuate the gain or suppress the low-frequency large audio signal, so that the diaphragm displacement of the speaker is also 0.43mm in a low pressure environment. about. The diaphragm displacement of the speaker under normal temperature and pressure is shown in Figure 4A, and the damped diaphragm displacement after the resonant frequency F0 is reduced is shown in Figure 4B. It can be seen that by configuring the target audio parameters, the diaphragm displacement of the speaker can be prevented from exceeding the preset vibration. membrane displacement.

In a possible embodiment, the altitude of the current electronic device can also be obtained through the positioning module of the electronic device, such as GPS, and the set of mapping relationships between altitude and air pressure can be queried to determine the altitude reference air pressure corresponding to the altitude, and further determine the altitude. Whether the reference air pressure belongs to a low air pressure environment, so as to configure the relevant audio parameters of the speaker and prevent the diaphragm displacement of the speaker from exceeding the preset diaphragm displacement.

In this way, the altitude reference air pressure corresponding to the altitude can be used as a comparison. When the difference between the altitude reference air pressure and the air pressure state reflected by the actual resonance frequency is too large, the lift information can be generated and fed back to the user. The prompt information is used to remind the user of the currently detected air pressure. Status may be abnormal.

Through the above speaker parameter configuration method, the ambient air pressure change can be simulated according to the change of the speaker resonance frequency after eliminating the interference of the ambient temperature factor, and then the appropriate audio parameters can be configured, which is suitable for a variety of environments and saves hardware costs.
