In the embodiment of the present invention, the electronic apparatus generates sound by means of vibration of the ceramic speaker 2 and the housing 1. Specifically, the exciter included in the ceramic speaker 2 may include a first piezoelectric ceramic piece, a second piezoelectric ceramic piece, and a metal piece, the first piezoelectric ceramic piece and the second piezoelectric ceramic piece are respectively bonded to two sides of the metal piece, and when the upper piezoelectric piece extends and the lower piezoelectric piece contracts, the exciter is bent upward. Thus, when an alternating voltage is applied to the actuator, it oscillates up and down with the alternating voltage. The amount of displacement is proportional to the amplitude of the input signal. The vibration of the exciter causes the housing 1 to flow ambient air, thereby producing sound.
In the embodiment of the present invention, the ceramic speaker 2 may be fixed between the battery panel and the middle frame support, the first capacitor plate 31 is disposed between the exciter and the housing 1, the second capacitor plate 32 is connected to a side of the exciter away from the housing 1, and the detection chip 33 is electrically connected to the first capacitor plate 31 and the second capacitor plate 32, respectively. Like this, compare in traditional moving coil loudspeaker, can avoid can setting up out the sound hole on electronic equipment's the surface, avoid causing the influence to electronic equipment's outward appearance, reduce electronic equipment's the waterproof degree of difficulty simultaneously.
Note that, since the first capacitor plate 31 is disposed between the exciter and the housing 1, the first capacitor plate 31 and the surface of the housing 1 away from the ceramic speaker 2 constitute a variable capacitance unit. When the operator's hand presses or touches the surface of the housing 1 away from the ceramic speaker 2, the variable capacitance unit is caused to change due to the electrification of the human hand and the change of the resonance point of the exciter and the housing 1 with the pressing of the operator's hand. In addition, the detection chip 33 is electrically connected to the first capacitor plate 31, so that the real-time capacitance value of the variable capacitor unit can be obtained in real time through the detection chip 33. The detection chip 33 may be built in the processor 4 or may be external to the processor 4. It should be noted that, in the embodiment of the present invention, the first capacitor plate 31 may be a conductive diaphragm, a metal thin film sensor, or another conductive thin film plate capable of forming a variable capacitor unit, which is not limited in the embodiment of the present invention.
The second capacitor plate 32 is arranged at one end of the exciter far away from the shell 1, the detection chip 33 is electrically connected with the first capacitor plate 31 and the second capacitor plate 32 respectively, and the first capacitor plate 31 and the second capacitor plate 32 form a variable capacitor unit. In the embodiment of the present invention, the types of the second capacitor plate 32 and the first capacitor plate 31 are the same, and details of the embodiment of the present invention are not repeated, because the second capacitor plate 32 is disposed at one end of the exciter away from the housing 1, and the first capacitor plate 31 and the second capacitor plate 32 form a variable capacitor unit, the second capacitor plate 32 can be grounded. Because the distance between first capacitor piece 31 and second capacitor piece 32 is unchangeable, and then when operator's hand held or pressed electronic equipment's casing 1 for the unipolar capacitance on first capacitor piece 31 changes, because second capacitor piece 32 ground connection again for the unipolar capacitance on second capacitor piece 32 is 0, and then when detecting, only need detect the unipolar capacitance on second capacitor piece 32 and can reflect real-time capacitance value. In addition, the second capacitor plate 32 can be a metal film, so that the capacitor interference far away from one side of the electronic device shell 1 can be shielded, the influence on the capacitor detected by the variable capacitor unit is avoided, and the detection precision is higher.
In addition, the driver 5 may be one of power amplifiers, and the driver 5 may be externally disposed on the ceramic speaker 2 or internally disposed on the ceramic speaker 2 for increasing the output power of the ceramic speaker 2. The power amplifier may be one of a charge pump type amplifier or a boost type amplifier. The driver 5 is electrically connected to the processor 4 and the exciter, and the processor 4 and the detection chip 33 are electrically connected, so that the driver 5 can change the output power of the ceramic speaker 2 by changing the vibration of the exciter. In this way, the processor 4 can process the real-time capacitance value of the variable capacitance unit acquired by the detection chip 33, and can also control the driver 5 to increase the output power of the ceramic speaker 2 according to the real-time capacitance value, thereby achieving the effect of adjusting the output volume of the ceramic speaker 2.
In the electronic device provided in the embodiment of the present invention, the capacitance detection assembly 3 includes a first capacitor plate 31, a second capacitor plate 32 and a detection chip 33, the first capacitor plate 31 is disposed between the exciter and the housing 1, the second capacitor plate 32 is connected to a side of the exciter away from the housing 1, the detection chip 33 is electrically connected to the first capacitor plate 31 and the second capacitor plate 32, respectively, the first capacitor plate 31 and the second capacitor plate 32 form a variable capacitance unit, a capacitance value of the variable capacitance unit changes along with deformation of the housing 1, and the detection chip 33 is used for acquiring a real-time capacitance value of the variable capacitance unit, so that when the housing 1 of the electronic device is held or pressed by an operator, the detection chip 33 can detect a change in the real-time capacitance value of the variable capacitance unit at any time; since the processor 4 is electrically connected to the driver 5 and the capacitance detecting element 3, respectively, and the driver 5 is electrically connected to the exciter, the processor 4 can control the driver 5 to adjust the output volume of the ceramic speaker 2 according to the real-time capacitance value, so that the volume of the ceramic speaker 2 is not affected by the holding or pressing of the operator.
Optionally, the processor 4 controls the output volume of the ceramic speaker 2 according to the real-time capacitance value, including:
the processor 4 determines a real-time compensation value of the ceramic loudspeaker 2 according to the real-time capacitance value and a threshold capacitance value, wherein the threshold capacitance value is a capacitance value obtained by the capacitance detection component 3 under the condition that the shell 1 is not deformed;
the driver 5 adjusts the output power of the ceramic speaker 2 based on the real-time compensation value of the ceramic speaker 2 to adjust the output volume of the ceramic speaker 2.
In the embodiment of the present invention, since the first capacitor plate 31 and the second capacitor plate 32 form a variable capacitor unit, the capacitance value of the variable capacitor unit changes along with the deformation of the housing 1, and the detection chip 33 is used for acquiring the real-time capacitance value of the variable capacitor unit, when the operator presses or touches the surface of the housing 1 far from the ceramic speaker 2, the hand of the operator is charged, and the resonance point of the exciter and the housing 1 changes along with the pressing of the operator, which causes the change of the variable capacitor unit. In addition, the detection chip 33 may be built in the processor 4, or may be externally disposed in the processor 4, the detection chip 33 is electrically connected to the first capacitor plate 31 and the second capacitor plate 32, and further, the real-time capacitance value of the variable capacitor unit formed by the first capacitor plate 31 and the second capacitor plate 32 may be obtained in real time through the detection chip 33.
It should be noted that the threshold capacitance value is a capacitance value obtained by the capacitance detection component 3 when the housing 1 is not deformed, and the threshold capacitance value may be a capacitance value of the variable capacitance unit detected by the capacitance detection component 3 when the exciter is at a normal resonance point with the housing 1 when the exciter does not press or touch the surface of the housing 1 away from the ceramic speaker 2.
In the embodiment of the present invention, after the processor 4 obtains the real-time capacitance value and the threshold capacitance value, the real-time capacitance value and the threshold capacitance value may be processed, and the real-time compensation value of the ceramic speaker 2 is determined according to, but not limited to, a relationship between the real-time capacitance value and the threshold capacitance value. For example, when the obtained real-time capacitance value is equal to or smaller than the threshold capacitance value, it may be determined that the ceramic speaker 2 is in a normal sound production state, that is, the sound volume emitted by the ceramic speaker 2 is the sound volume that can be heard by the ear of the operator, and it may be determined that the real-time compensation value of the ceramic speaker 2 is 0, that is, the ceramic speaker 2 does not need to be compensated. If the acquired real-time capacitance value is larger than the threshold capacitance value, it can be determined that the ceramic speaker 2 is in an abnormal sounding state, that is, the operator presses or touches the surface of the shell 1 far away from the ceramic speaker 2, so that the resonance point of the exciter and the shell 1 is changed, the volume of the ceramic speaker 2 is reduced, the volume of the ceramic speaker 2 needs to be compensated, and the human ear can hear the sound.
Then, since the volume compensation of the ceramic speaker 2 is only required in a state where the resonance point of the exciter is changed by pressing or touching the surface of the housing 1 away from the ceramic speaker 2 with the hand of the operator, the generated volume gain commands are all commands for increasing the volume of the ceramic speaker 2 after the real-time compensation value of the ceramic speaker 2 is determined. The volume gain command is a command for triggering the driver 5 to perform power amplification.
When the volume gain instruction is generated, the volume gain instruction may be sent to the driver 5, and since the volume gain instruction is an instruction for triggering the driver 5 to perform power amplification, the output power of the ceramic speaker 2 may be adjusted after the driver 5 receives the volume gain instruction, so as to adjust the output volume of the ceramic speaker 2.
Thus, the processor 4 determines a real-time compensation value of the ceramic speaker 2 according to the real-time capacitance value and a threshold capacitance value, wherein the threshold capacitance value is a capacitance value obtained by the capacitance detection component 3 under the condition that the housing 1 is not deformed; then, the driver 5 adjusts the output power of the ceramic speaker 2 based on the real-time compensation value of the ceramic speaker 2, so that the volume of the ceramic speaker 2 is increased, and further, when the electronic device housing 1 is held by an operator or the electronic device housing 1 is pressed, the volume of the ceramic speaker 2 is not affected.
Optionally, the processor 4 is configured to: determining a real-time capacitance difference value according to the real-time capacitance value and the threshold capacitance value;
and determining a real-time compensation value of the ceramic loudspeaker 2 according to the real-time capacitance difference value.
In the embodiment of the present invention, when the real-time capacitance difference is a positive value, it indicates that the obtained real-time capacitance value is greater than the threshold capacitance value, and it can be determined that the ceramic speaker 2 is in an abnormal sounding state, that is, an operator presses or touches the surface of the housing 1 away from the ceramic speaker 2, so that a resonance point of the exciter and the housing 1 is changed, and the volume of the ceramic speaker 2 is reduced, and the volume of the ceramic speaker 2 needs to be compensated, so that a human ear can hear the sound. When the implementation capacitance value is less than or equal to 0, it indicates that the acquired real-time capacitance value is equal to or less than the threshold capacitance value, and it may be determined that the ceramic speaker 2 is in a normal sound production state, that is, the volume emitted by the ceramic speaker 2 is the volume that can be heard by the ear of the operator, and it may be determined that the real-time compensation value of the ceramic speaker 2 is 0, that is, the ceramic speaker 2 does not need to be compensated.
Optionally, the processor 4 is configured to: acquiring a preset capacitance value range and a preset compensation value; generating a corresponding relation between the preset capacitance value range and the preset compensation value based on the preset capacitance value range and the preset compensation value; and determining a real-time compensation value of the ceramic loudspeaker 2 based on the real-time capacitance difference value and the corresponding relation.
In the embodiment of the present invention, the preset capacitance range and the preset compensation value may be stored in the processor 4 according to the normal volume that can be heard by human ears. The preset compensation value may be determined according to the type of the driver 5. After the preset capacitance range and the preset compensation value are obtained, a correspondence between the preset capacitance range and the preset compensation value may be generated, and the generated correspondence between the preset capacitance range and the preset compensation value may be stored in the processor 4. The corresponding relationship may be a one-to-one mapping relationship. Table 1 is a table of correspondence between a preset capacitance range and a preset compensation value, for example, as shown in table 1:
TABLE 1
| Preset range of capacitance (F) | Preset offset (dB) |
| (0,5] | 1.5 |
| (5,10] | 3 |
| (10,15] | 4.5 |
| ＞15 | 6 |
When the capacitance value is greater than 0F and less than or equal to 5F, the corresponding preset compensation value is 1.5dB, when the capacitance value is greater than 5F and less than or equal to 10F, the corresponding preset compensation value is 3dB, when the capacitance value is greater than 10F and less than or equal to 15F, the corresponding preset compensation value is 4.5dB, and when the capacitance value is greater than 15F, the corresponding preset compensation value is 6 dB. The above embodiment is merely an example, and the specific numerical value is determined depending on the type of the ceramic speaker 2. When the real-time compensation value of the ceramic speaker 2 needs to be determined, the corresponding relationship between the pre-stored preset capacitance range and the pre-stored preset compensation value and the real-time capacitance difference value can be obtained, and the real-time compensation value of the ceramic speaker 2 is determined.
Optionally, the processor 4 is configured to:
if the real-time capacitance difference value is less than or equal to 0, determining the compensation value of the ceramic loudspeaker to be 0;
if the real-time capacitance difference value is within a first preset capacitance value range, determining the compensation value of the ceramic loudspeaker as a first compensation value;
if the real-time capacitance difference value is within a second preset capacitance value range, determining the compensation value of the ceramic loudspeaker as a second compensation value;
if the real-time capacitance difference value is within a third preset capacitance value range, determining the compensation value of the ceramic loudspeaker as a third compensation value;
and if the real-time capacitance difference value is within a fourth preset capacitance range, determining the compensation value of the ceramic loudspeaker to be a fourth compensation value, wherein the second compensation value is greater than the first compensation value, the third compensation value is greater than the second compensation value, and the fourth compensation value is greater than the third compensation value.
In the embodiment of the present invention, after the corresponding relationship between the preset capacitance range and the compensation value is generated, since the corresponding relationship may be a one-to-one mapping relationship, any real-time capacitance value may correspond to a preset compensation value. If the corresponding relationship between the preset capacitance range and the preset compensation value is the relationship shown in table 1, for example, if the obtained real-time capacitance value is 13F, it can be determined that the real-time capacitance value is located in the preset capacitance range of (10, 15), and according to the corresponding relationship, it can be determined that the compensation value of the ceramic loudspeaker is 4.5 dB.
It should be noted that the first preset capacitance range, the second preset capacitance range, the third preset capacitance range, and the fourth preset capacitance range may be equal capacitance intervals or unequal capacitance intervals. In addition, in one possible implementation manner, the second compensation value may be equal to 2 times the first compensation value, the third compensation value may be equal to 3 times the first compensation value, and the fourth compensation value may be equal to 4 times the first compensation value.
It should be noted that, because the preset capacitance range can be divided into a first preset capacitance range, a second preset capacitance range, a third preset capacitance range and a fourth preset capacitance range, the division of the preset capacitance range is more detailed, the corresponding relationship between the real-time capacitance and the real-time compensation value of the ceramic speaker 2 is more definite, and it is avoided that the corresponding real-time compensation value is relatively single due to the overlarge preset capacitance range, and the compensation effect of the volume of the ceramic speaker 2 is not affected.
In the electronic device provided in the embodiment of the present invention, the capacitance detection assembly 3 includes a first capacitor plate 31, a second capacitor plate 32 and a detection chip 33, the first capacitor plate 31 is disposed between the exciter and the housing 1, the second capacitor plate 32 is connected to a side of the exciter away from the housing 1, the detection chip 33 is electrically connected to the first capacitor plate 31 and the second capacitor plate 32, respectively, the first capacitor plate 31 and the second capacitor plate 32 form a variable capacitance unit, a capacitance value of the variable capacitance unit changes along with deformation of the housing 1, and the detection chip 33 is used for acquiring a real-time capacitance value of the variable capacitance unit, so that when the housing 1 of the electronic device is held or pressed by an operator, the detection chip 33 can detect a change in the real-time capacitance value of the variable capacitance unit at any time; since the processor 4 is electrically connected to the driver 5 and the capacitance detecting element 3, respectively, and the driver 5 is electrically connected to the exciter, the processor 4 can control the driver 5 to adjust the output volume of the ceramic speaker 2 according to the real-time capacitance value, so that the volume of the ceramic speaker 2 is not affected by the holding or pressing of the operator.
In addition, because predetermine the capacitance value scope and can divide into first predetermined capacitance value scope, the capacitance value scope is predetermine to the second, the capacitance value scope is predetermine to the third and the capacitance value scope is predetermine to the fourth, consequently, make the division of predetermineeing the capacitance value scope more careful, make the corresponding relation of real-time capacitance value and ceramic speaker 2's real-time compensation value more clear and definite, avoid leading to corresponding real-time compensation value comparatively single because of predetermineeing the capacitance value scope too big, can not cause the influence to the compensation effect of ceramic speaker 2's volume.
Referring to fig. 2, a second embodiment of the present invention further provides a volume adjustment method for a ceramic speaker 2, which is applied to an electronic device in the first embodiment of the present invention, and the volume adjustment method includes:
step 201: and controlling the driver 5 to adjust the output volume of the ceramic loudspeaker 2 according to the real-time capacitance value.
It should be noted that, the specific process of the volume adjustment method may be:
determining a real-time compensation value of the ceramic loudspeaker 2 according to the real-time capacitance value and a threshold capacitance value, wherein the threshold capacitance value is a capacitance value obtained by the capacitance detection component 3 under the condition that the shell 1 is not deformed;
the output power of the ceramic speaker 2 is adjusted based on the real-time compensation value of the ceramic speaker 2 to adjust the output volume of the ceramic speaker 2.

The detection chip 33 may be built in the processor 4, or may be externally disposed in the processor 4, and the detection chip 33 is electrically connected to the first capacitor plate 31, so that the real-time capacitance value of the variable capacitor unit can be obtained in real time through the detection chip 33.
It should be noted that the threshold capacitance value is a capacitance value obtained by the capacitance detection component 3 when the housing 1 is not deformed, and the threshold capacitance value may be a capacitance value of the variable capacitance unit detected by the capacitance detection component 3 when the exciter is at a normal resonance point with the housing 1 when the exciter does not press or touch the surface of the housing 1 away from the ceramic speaker 2.
In the embodiment of the present invention, after the processor 4 obtains the real-time capacitance value and the threshold capacitance value, the real-time capacitance value and the threshold capacitance value may be processed, and the real-time compensation value of the ceramic speaker 2 is determined according to, but not limited to, a relationship between the real-time capacitance value and the threshold capacitance value. For example, when the obtained real-time capacitance value is equal to or smaller than the threshold capacitance value, it may be determined that the ceramic speaker 2 is in a normal sound production state, that is, the sound volume emitted by the ceramic speaker 2 is the sound volume that can be heard by the ear of the operator, and it may be determined that the real-time compensation value of the ceramic speaker 2 is 0, that is, the ceramic speaker 2 does not need to be compensated. If the acquired real-time capacitance value is larger than the threshold capacitance value, it can be determined that the ceramic speaker 2 is in an abnormal sounding state, that is, the operator presses or touches the surface of the shell 1 far away from the ceramic speaker 2, so that the resonance point of the exciter and the shell 1 is changed, the volume of the ceramic speaker 2 is reduced, the volume of the ceramic speaker 2 needs to be compensated, and the human ear can hear the sound.
Then, since the volume compensation of the ceramic speaker 2 is only required in a state where the resonance point of the exciter is changed by pressing or touching the surface of the housing 1 away from the ceramic speaker 2 with the hand of the operator, the generated volume gain commands are all commands for increasing the volume of the ceramic speaker 2 after the real-time compensation value of the ceramic speaker 2 is determined. The volume gain command is a command for triggering the driver 5 to perform power amplification.
When the volume gain instruction is generated, the volume gain instruction may be sent to the driver 5, and since the volume gain instruction is an instruction for triggering the driver 5 to perform power amplification, the output power of the ceramic speaker 2 may be adjusted after the driver 5 receives the volume gain instruction, so as to adjust the output volume of the ceramic speaker 2.
Like this, processor 4 can confirm the real-time compensation value of ceramic speaker 2 according to the real-time capacitance value that electric capacity determine module 3 acquireed, and later, driver 5 is based on the real-time compensation value of ceramic speaker 2, adjusts the output of ceramic speaker 2 for the volume of ceramic speaker 2 obtains improving, and then when casing 1 of electronic equipment was held or was pressed electronic equipment's casing 1 by operator's hand, also can not cause the influence to the volume of ceramic speaker 2.
In the volume adjusting method provided by the embodiment of the invention, because the electronic device can adjust the output volume of the ceramic speaker 2 according to the real-time capacitance value control driver 5, when the housing 1 of the electronic device is held or pressed by the hand of an operator, the capacitance detecting component 3 included in the electronic device can detect the change of the real-time capacitance value of the variable capacitance unit at any time; the electronic device then comprises a processor 4 for adjusting the output volume of the ceramic speaker 2 according to the real-time capacitance value control driver 5, so that the volume of the ceramic speaker 2 is not affected by the holding or pressing of the operator's hand.
Referring to fig. 3, a third embodiment of the present invention further provides another volume adjustment method for a ceramic speaker 2, which is applied to an electronic device according to the first embodiment of the present invention, and the method includes:
step 301: and determining a real-time capacitance difference value according to the real-time capacitance value and the threshold capacitance value.
In the embodiment of the present invention, since the first capacitor plate 31 and the second capacitor plate 32 form a variable capacitor unit, the capacitance value of the variable capacitor unit changes along with the deformation of the housing 1, and the detection chip 33 is used for acquiring the real-time capacitance value of the variable capacitor unit, when the operator presses or touches the surface of the housing 1 far from the ceramic speaker 2, the hand of the operator is charged, and the resonance point of the exciter and the housing 1 changes along with the pressing of the operator, which causes the change of the variable capacitor unit. The detection chip 33 may be built in the processor 4, or may be externally disposed in the processor 4, and the detection chip 33 is electrically connected to the first capacitor plate 31, so that the real-time capacitance value of the variable capacitor unit can be obtained in real time through the detection chip 33.
It should be noted that the threshold capacitance value is a capacitance value obtained by the capacitance detection component 3 when the housing 1 is not deformed, and the threshold capacitance value may be a capacitance value of the variable capacitance unit detected by the capacitance detection component 3 when the exciter is at a normal resonance point with the housing 1 when the exciter does not press or touch the surface of the housing 1 away from the ceramic speaker 2.
When the real-time capacitance difference value is a positive value, it indicates that the acquired real-time capacitance value is greater than the threshold capacitance value, and it can be determined that the ceramic speaker 2 is in an abnormal sounding state, that is, the operator presses or touches the surface of the shell 1 away from the ceramic speaker 2, so that the resonance point of the exciter and the shell 1 is changed, the volume of the ceramic speaker 2 is reduced, the volume of the ceramic speaker 2 needs to be compensated, and the human ear can hear the sound. When the implementation capacitance value is less than or equal to 0, it indicates that the acquired real-time capacitance value is equal to or less than the threshold capacitance value, and it may be determined that the ceramic speaker 2 is in a normal sound production state, that is, the volume emitted by the ceramic speaker 2 is the volume that can be heard by the ear of the operator, and it may be determined that the real-time compensation value of the ceramic speaker 2 is 0, that is, the ceramic speaker 2 does not need to be compensated.
Step 302: and determining a real-time compensation value of the ceramic loudspeaker 2 according to the real-time capacitance difference value.
In the embodiment of the present invention, when the real-time capacitance difference is a positive value, it indicates that the obtained real-time capacitance value is greater than the threshold capacitance value, and it can be determined that the ceramic speaker 2 is in an abnormal sounding state, that is, an operator presses or touches the surface of the housing 1 away from the ceramic speaker 2, so that a resonance point of the exciter and the housing 1 is changed, and the volume of the ceramic speaker 2 is reduced, and the volume of the ceramic speaker 2 needs to be compensated, so that a human ear can hear the sound. When the implementation capacitance value is less than or equal to 0, it indicates that the acquired real-time capacitance value is equal to or less than the threshold capacitance value, and it may be determined that the ceramic speaker 2 is in a normal sound production state, that is, the volume emitted by the ceramic speaker 2 is the volume that can be heard by the ear of the operator, and it may be determined that the real-time compensation value of the ceramic speaker 2 is 0, that is, the ceramic speaker 2 does not need to be compensated.
Optionally, the step of determining a real-time compensation value of the ceramic speaker 2 according to the real-time capacitance difference may include: acquiring a preset capacitance value range and a preset compensation value; generating a corresponding relation between the preset capacitance value range and the preset compensation value based on the preset capacitance value range and the preset compensation value; and determining a real-time compensation value of the ceramic loudspeaker 2 based on the real-time capacitance difference value and the corresponding relation.
In the embodiment of the present invention, the preset capacitance range and the preset compensation value may be stored in the processor 4 according to the normal volume that can be heard by human ears. The preset compensation value may be determined according to the type of the driver 5. After the preset capacitance range and the preset compensation value are obtained, a correspondence between the preset capacitance range and the preset compensation value may be generated, and the generated correspondence between the preset capacitance range and the preset compensation value may be stored in the processor 4. The corresponding relationship may be a one-to-one mapping relationship. Table 1 is a table of correspondence between a preset capacitance range and a preset compensation value, for example, as shown in table 1:
TABLE 1
| Preset range of capacitance (F) | Preset offset (dB) |
| (0,5] | 1.5 |
| (5,10] | 3 |
| (10,15] | 4.5 |
| ＞15 | 6 |
When the capacitance value is greater than 0F and less than or equal to 5F, the corresponding preset compensation value is 1.5dB, when the capacitance value is greater than 5F and less than or equal to 10F, the corresponding preset compensation value is 3dB, when the capacitance value is greater than 10F and less than or equal to 15F, the corresponding preset compensation value is 4.5dB, and when the capacitance value is greater than 15F, the corresponding preset compensation value is 6 dB. The above embodiment is merely an example, and the specific numerical value is determined depending on the type of the ceramic speaker 2. When the real-time compensation value of the ceramic speaker 2 needs to be determined, the corresponding relationship between the pre-stored preset capacitance range and the pre-stored preset compensation value and the real-time capacitance difference value can be obtained, and the real-time compensation value of the ceramic speaker 2 is determined.
Optionally, the step of determining a real-time compensation value of the ceramic speaker 2 based on the real-time capacitance difference value and the corresponding relationship may include:
if the real-time capacitance difference value is less than or equal to 0, determining the compensation value of the ceramic loudspeaker to be 0;
if the real-time capacitance difference value is within a first preset capacitance value range, determining the compensation value of the ceramic loudspeaker as a first compensation value;
if the real-time capacitance difference value is within a second preset capacitance value range, determining the compensation value of the ceramic loudspeaker as a second compensation value;
if the real-time capacitance difference value is within a third preset capacitance value range, determining the compensation value of the ceramic loudspeaker as a third compensation value;
and if the real-time capacitance difference value is within a fourth preset capacitance range, determining the compensation value of the ceramic loudspeaker to be a fourth compensation value, wherein the second compensation value is greater than the first compensation value, the third compensation value is greater than the second compensation value, and the fourth compensation value is greater than the third compensation value.
In the embodiment of the present invention, after the corresponding relationship between the preset capacitance range and the compensation value is generated, since the corresponding relationship may be a one-to-one mapping relationship, any real-time capacitance value may correspond to a preset compensation value. If the corresponding relationship between the preset capacitance range and the preset compensation value is the relationship shown in table 1, for example, if the obtained real-time capacitance value is 13F, it can be determined that the real-time capacitance value is located in the preset capacitance range of (10, 15), and according to the corresponding relationship, it can be determined that the compensation value of the ceramic loudspeaker is 4.5 dB.
It should be noted that the first preset capacitance range, the second preset capacitance range, the third preset capacitance range, and the fourth preset capacitance range may be equal capacitance intervals or unequal capacitance intervals. In addition, in one possible implementation manner, the second compensation value may be equal to 2 times the first compensation value, the third compensation value may be equal to 3 times the first compensation value, and the fourth compensation value may be equal to 4 times the first compensation value.
It should be noted that, because the preset capacitance range can be divided into a first preset capacitance range, a second preset capacitance range, a third preset capacitance range and a fourth preset capacitance range, the division of the preset capacitance range is more detailed, the corresponding relationship between the real-time capacitance and the real-time compensation value of the ceramic speaker 2 is more definite, and it is avoided that the corresponding real-time compensation value is relatively single due to the overlarge preset capacitance range, and the compensation effect of the volume of the ceramic speaker 2 is not affected. .
In the embodiment of the present invention, the processor 4 may determine the real-time compensation value of the ceramic speaker 2 according to the real-time capacitance value of the variable capacitance unit acquired by the capacitance detection component 3 and then according to the real-time capacitance value and the threshold capacitance value, generate the volume gain instruction based on the real-time compensation value of the ceramic speaker 2, and send the volume gain instruction to the driver 5, so that the volume of the ceramic speaker 2 is increased, and further, when the housing 1 of the electronic device is held by the hand of an operator or the housing 1 of the electronic device is pressed, the volume of the ceramic speaker 2 is not affected.
In addition, because predetermine the capacitance value scope and can divide into first predetermined capacitance value scope, the capacitance value scope is predetermine to the second, the capacitance value scope is predetermine to the third and the capacitance value scope is predetermine to the fourth, consequently, make the division of predetermineeing the capacitance value scope more careful, make the corresponding relation of real-time capacitance value and ceramic speaker 2's real-time compensation value more clear and definite, avoid leading to corresponding real-time compensation value comparatively single because of predetermineeing the capacitance value scope too big, can not cause the influence to the compensation effect of ceramic speaker 2's volume.
Step 303: the output power of the ceramic speaker 2 is adjusted based on the real-time compensation value of the ceramic speaker 2 to adjust the output volume of the ceramic speaker 2.
In an embodiment of the present invention, when the real-time compensation value for ceramic speaker 2 is determined, processor 4 may generate an instruction to increase the volume of ceramic speaker 2. The volume gain command is a command for triggering the driver 5 to perform power amplification.
When the volume gain instruction is generated, the volume gain instruction may be sent to the driver 5, and since the volume gain instruction is an instruction for triggering the driver 5 to perform power amplification, the output power of the ceramic speaker 2 may be adjusted after the driver 5 receives the volume gain instruction, so as to adjust the output volume of the ceramic speaker 2.
Like this, processor 4 can confirm the real-time compensation value of ceramic speaker 2 according to the real-time capacitance value that electric capacity determine component 3 acquireed, and later, driver 5 is based on the real-time compensation value of ceramic speaker 2, adjusts ceramic speaker 2's output for the volume of ceramic speaker 2 obtains improving, and then when electronic equipment casing 1 was held or was pressed electronic equipment's casing 1 by operator's hand, also can not cause the influence to the volume of ceramic speaker 2.
