FIG. 1 shows a flow diagram of an actuator regulation method according to an embodiment of the invention. As shown in fig. 1, in one embodiment, the actuator regulating method may include the following steps S110 to S130.
At step S110, at least two actuators on the sound emitting panel are selected.
In this step, in order to reduce power consumption, the number of actuators selected may be equal to 2 when the actuator on the sound emission panel is selected for the first time.
In step S120, performance characteristics of the at least two actuators are determined based on the tuning parameters of each of the selected actuators.
And step S130, adjusting the regulation and control parameters of each exciter so that the performance characteristics meet preset conditions.
According to the exciter regulating method provided by the embodiment of the invention, at least two exciters can be selected from a plurality of exciters on the sound production panel, and the performance characteristics of the at least two exciters can meet the preset condition by adjusting the regulating parameters of each exciter in the selected exciters. And when the performance characteristics of the at least two exciters meet preset conditions, the acoustic index of the processed audio signal conforms to the preset psychoacoustic index of an audio receiver.
Fig. 2 shows a schematic diagram of the position relationship between a listening object and a sound emitting panel in an embodiment of the invention. As shown in fig. 2, in one embodiment, listening object 22 of the audio signal may be an object that receives the audio signal, such as an ear of a user of electronic device 20, a listening device, or the like. The electronic device 20 may be a mobile terminal, such as a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), and the like.
Due to the randomness of the positional relationship between the listening object 22 and the sound emitting panel 21 in the actual scene, when it is determined that the audio signal needs to be played using the sound emitting panel 21, the distance between the listening object 22 and the sound emitting panel 21 may be detected by a distance measuring sensor, such as an ultrasonic sensor or an optical sensor, on the plane on which the sound emitting panel 21 is located.
It should be noted that the number and arrangement of the sensors on the plane where the sound emitting panel is located may be set according to actual needs, and the embodiment of the present invention is not particularly limited.
In one embodiment, the ranging sensor on the plane of the sound emitting panel includes a transmitter and a receiver. A transmitter for transmitting beams (ultrasound or light waves) in a plurality of directions, the beams reaching the surface of the listening object forming sampling points on the surface of the listening object; the beam reaching the surface of the listening object is reflected by the surface of the listening object, and the reflected beam is received by the receiver as an incident beam of the sound emitting panel.
In one embodiment, the ranging sensor may record the beam transmission time from transmitting the beam to receiving the incident beam and use the distance calculated from the beam transmission time and the beam propagation velocity as the distance from the sound-emitting panel to the sampling points on the surface of the listening object, and the distance from the sound-emitting panel to the different sampling points on the surface of the listening object may be calculated from the ranging sensor.
In another embodiment, the angle of incidence of the incident beam on the sound-emitting panel, which is the angle the beam makes with the normal to the interface when it is incident on the interface with the sound-emitting panel, can be measured by a beam analyzer located on the electronic device or on the sound-emitting panel. As shown in fig. 2, the angle θ between the incident beam and the plane of the sound-emitting panel can be determined according to the incident angle of the incident beam on the sound-emitting panel. In the embodiment of the present invention, the included angle θ may be used as an included angle between the listening object and the sound emitting panel.
As can be seen from the above description, if it is detected that the included angle between the listening object and the sound emitting panel satisfies the preset angle limiting condition, the distance from the sound emitting panel corresponding to the incident beam forming the included angle to the sampling point on the surface of the listening object can be taken as the shortest distance between the listening object and the sound emitting panel; and taking the incident point of the incident beam forming the included angle on the sounding panel or the vertical point of the sampling point on the surface of the listening object corresponding to the shortest distance on the sounding panel as a reference position point on the sounding panel.
In one embodiment, the preset angle limit condition includes: the included angle between the listening object and the sound production panel is equal to the preset angle threshold value. As an example, the preset angle threshold may be, for example, 90 ° or an angle difference from 90 ° less than or equal to a preset angle difference threshold. In this embodiment, the closer the preset angle threshold is to 90 °, the more accurate the detected shortest distance to the sound emitting panel.
In one embodiment, the tilt angle of the electronic device where the sound emitting panel is located may be determined by a sensing result of an angle measurement module, and the angle measurement module may be located at the electronic device where the sound emitting panel is located. As an example, the angle measurement module may include a gravity sensor, and the gravity sensor may sense an angle between an axis direction of the electronic device and a horizontal plane.
As an example, the angle measurement module may include at least one of a gravity sensor, a linear accelerometer, a gyroscope, a tilt sensor, and the like, for improving accuracy and diversity of the sensed tilt angle of the electronic device.
In this embodiment, the sensed tilt angle of the electronic device may be used as the tilt angle of the sound emitting panel on the electronic device.
In one embodiment, the designated reference location point may be determined from the sound-emitting panel when the distance between the listening object and the sound-emitting panel is within a preset distance threshold range and the tilt angle of the sound-emitting panel is within a preset angle threshold range.
In one embodiment, when the exciter is used for controlling the sounding panel to sound, the specified reference position point can be obtained from the sounding panel only according to the distance between the listening object and the sounding panel; in another embodiment, if no listening object is present, or when the distance between the listening object and the sound emitting panel cannot be detected by the ranging sensor, the designated reference location point may be obtained from the sound emitting panel based only on the sensed tilt angle of the electronic device or the sound emitting panel.
In the embodiment of the present invention, the correspondence between the distance between the listening object and the sound emitting panel and/or the inclination angle of the sound emitting panel and the reference position point on the sound emitting panel may be set in advance. Thereby, the reference position point on the sound emitting panel is determined according to at least one of the detected distance between the listening object and the sound emitting panel and the sensed inclination angle of the sound emitting panel by using the corresponding relation.
As can be seen from the description of the above embodiments, in an embodiment, the step of selecting at least two exciters on the sound emitting panel in step S110 may specifically include: steps S111 and S112.
Step S111, when the triggering condition is satisfied, determining a reference position point on the sound production panel according to the detected distance between the listening object and the sound production panel and/or the detected inclination angle of the sound production panel; in step S112, at least two actuators closest to the reference position point are selected.
In one embodiment, the trigger condition may include detecting that the electronic device is in need of playing audio or answering a call.
According to the exciter regulating method, at least two exciters which are positioned on the sounding panel and are closest to the reference point are selected, and the regulating parameters of each exciter are adjusted, so that the performance characteristics of the selected at least two exciters meet preset conditions, and the performance limitation and the deficiency of a single exciter are improved and compensated.
In the embodiment of the present invention, the sweet spot of the sound emission panel can be determined according to the size and dimensions of the sound emission panel. The acoustic index of the audio signal received by the sweet spot is better than the acoustic index of the audio signal received by the other listening positions of the sound panel (which may be referred to as the sweet spot below). The embodiment of the invention can preset the standard performance characteristics of at least two selected exciters based on the optimal acoustic index.
As an example, when the sensor detects that the spatial angle formed by the incident beam and the sound emitting panel is a specified angle value, and the distance between the listening object and a specified top end of the electronic device where the sound emitting panel is located is a specified distance value, the spatial location of the listening object is the optimal listening position for the sound emitting panel to sound under the action of the exciter, and is also the optimal audio receiving position according to the optimal acoustic index or the ideal acoustic index of psychoacoustics.
In an embodiment, the performance characteristic in step S130 satisfies a preset condition, which may specifically include: and the characteristic similarity between the preset standard performance characteristics of the at least two selected actuators is less than or equal to a preset similarity threshold.
FIG. 3a is a graph showing a comparison of performance characteristics of multiple actuators in an exemplary embodiment of the invention; fig. 3b shows a comparison of performance characteristics of a multi-exciter in another exemplary embodiment of the invention. In fig. 3a and 3b, the X-axis represents a frequency band, and the Y-axis represents the loudness of an audio signal when a voltage is used as a measurement object.
As shown in fig. 3a, "pre-filter response curve of low frequency sound unit", the loudness of the unprocessed audio signal is between 60dbv and nearly 102dbv in the frequency range of 100Hz to 10 kHz; as shown in fig. 3a, "frequency response curve after filtering by low frequency sound generating unit", after being processed by a multi-exciter comprising a low frequency characteristic exciter, an audio signal with loudness between 80dbv and nearly 102dbv is obtained.
As shown in fig. 3b, "pre-filtering frequency response curve of mid-high frequency sound generating unit", the loudness of the unprocessed audio signal is between 60dbv and nearly 105dbv in the frequency range of 1kHz to 10 kHz; as shown in "the filtered frequency response curve of the middle-high frequency sound production unit" in fig. 3b, after being processed by the multi-driver including the middle-high frequency characteristics, the audio signal with the loudness between approximately 97dbv and approximately 105dbv is obtained.
As can be seen from fig. 3a and 3b, after the plurality of drivers process the audio signals according to their own characteristics, the wide and flat audio signals can be finally output through the sound generating unit, so that the loudness of the audio signals is improved, and the human voice signals or music signals in the audio signals are restored with high fidelity. Illustratively, the sound generating unit may be a sound generating panel such as a full-face screen in the embodiment of the present invention, and may also be a housing or a speaker of the electronic device.
In an embodiment, in step S130, the step of adjusting the control parameter of each actuator may specifically include: one of the preset control parameter values of each exciter is selected.
In the embodiment of the invention, when the selected regulation parameter value of each exciter is adjusted, the regulation parameter of each exciter can be specifically adjusted according to the preset regulation parameter value of each exciter, so that blind parameter adjustment is avoided, and the parameter adjustment efficiency is improved.
In one embodiment, the actuator regulating method may further include the following step S140.

In this step, the other actuators may be actuators other than the actuator selected last time, which are closest to the reference position point on the sound emission panel.
In this embodiment, if the performance characteristics of the selected exciter do not satisfy the predetermined standard performance condition after adjusting the tuning parameters of each exciter, the exciter closest to the reference point on the sound emitting panel may be additionally selected on the basis of the selected exciter, and the tuning parameters of each exciter may be adjusted for the selected exciter and the additionally selected exciter so that the performance characteristics of the selected exciter satisfy the predetermined condition, so that the listening position can receive the high-quality audio signal.
In one embodiment, when the number of the sound emitting panels is greater than 1, the step of selecting at least two drivers on the sound emitting panel in step S110 may further include: the sound emission panel to be used is determined based on the biometric result.
In this embodiment, when a user needs to make a call with the electronic device, the electronic device may first perform biometric recognition with a biometric recognition device on the electronic device, determine a used sounding panel among the multiple sounding panels of the electronic device according to a result of the biometric recognition, determine a reference location point on the used sounding panel according to a detected tilt angle of the sounding panel and/or a detected distance between a listening object and the sounding panel, select at least two drivers of the used sounding panel that are closest to the reference location point, and adjust a control parameter of each driver so that a performance characteristic of the selected driver satisfies a preset condition.
According to the exciter regulating and controlling method provided by the embodiment of the invention, at least two exciters can be selected from the sounding panel, the regulating and controlling parameter of each selected exciter is regulated, so that the performance characteristic of the selected exciter meets the preset condition, and the regulated exciter has a better low-frequency compensation or high-frequency compensation effect on the audio signal, thereby obtaining the high-quality audio signal.
In one embodiment, the actuator regulation method may further comprise: and controlling the sounding panel to sound by using the adjusted regulation and control parameters of each exciter. In the embodiment, the sound-emitting panel is controlled to emit sound by using the adjusted regulation and control parameters of each exciter, so that the audio quality of the sound-emitting panel under the exciter when the sound-emitting panel plays audio can be improved.

In this step, when the at least two selected actuators are the actuator a and the actuator B, one control parameter value is selected from preset control parameter values a 0-An of the actuator a, and one control parameter value is selected from preset control parameter values B0-Bm of the actuator B. Wherein n and m are integers of 1 or more.

As one example, the frequency response curve may be used to reflect the frequency response characteristics of the exciter. The frequency response characteristics of the exciter which accord with the optimal acoustic index or the ideal acoustic index can be reflected through a preset standard frequency response curve. Specifically, the standard frequency response curve may be an optimal frequency response curve that can be achieved after the performance characteristics of the actuators on the sound emitting panel are superimposed. The standard frequency response curve of the embodiment of the invention can also be called a reference frequency response curve.
