在本发明实施例提供的电子设备及其音量调节方法中，由于电容检测组件包括第一电容片、第二电容片和检测芯片，第一电容片设置连接激励器和壳体之间，第二电容片连接在激励器的远离壳体的一侧，检测芯片分别与第一电容片和第二电容片电连接，第一电容片和第二电容片组成可变电容单元，可变电容单元的电容值随壳体的形变而发生变化，检测芯片用于获取可变电容单元的实时电容值，因此，当电子设备的壳体被操作者的手握住或者按压住时，电容检测组件可以随时检测可变电容单元的实时电容值的变化；又由于处理器分别与驱动器和电容检测组件电连接，所述驱动器和所述激励器电连接，因此，处理器可以根据实时电容值控制驱动器调节所述陶瓷扬声器的输出音量，进而使陶瓷扬声器的音量不受操作者的手握住或者按压影响。

应理解，说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本发明的至少一个实施例中。因此，在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外，这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本发明的各种实施例中，应理解，下述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
参见图1，本发明实施例一提供了一种电子设备，该电子设备包括壳体1、陶瓷扬声器2、电容检测组件3、处理器4和驱动器5；
陶瓷扬声器2设置于壳体1内，陶瓷扬声器2具有激励器，激励器与壳体1相连；
电容检测组件3包括第一电容片31、第二电容片32和检测芯片33，第一电容片31设置连接激励器和壳体1之间，第二电容片32连接在激励器的远离壳体1的一侧，电容检测组件3分别与第一电容片31和第二电容片32电连接，第一电容片31和第二电容片32组成可变电容单元，可变电容单元的电容值随壳体1的形变而发生变化，检测芯片33用于获取可变电容单元的实时电容值；
处理器4分别与驱动器5和电容检测组件3电连接，驱动器5和激励器电连接，处理器4根据实时电容值控制驱动器5调节陶瓷扬声器2的输出音量。
在本发明实施例中，电子设备依靠陶瓷扬声器2与壳体1的振动而发出声音。具体的，陶瓷扬声器2包括的激励器可以包括第一压电陶瓷片、第二压电陶瓷片和金属片，第一压电陶瓷片和第二压电陶瓷片分别粘接在金属片两面上，当上压电片伸展、下压电片收缩时，激励器就向上弯曲。因此，当给激励器加上一个交变电压，它就会随着电压的交替变化而上下振动。位移量与输入信号的幅度成正比。激励器的振动带动壳体1使周围空气流动，从而发出声音。
在本发明实施例中，可以将陶瓷扬声器2固定在电池板与中框支架之间，第一电容片31设置在激励器和壳体1之间，第二电容片32连接在激励器的远离壳体1的一侧，检测芯片33分别与第一电容片31和第二电容片32电连接。这样，相比于传统的动圈式扬声器，可以避免在电子设备的表面上可设出音孔，避免对电子设备的外观造成影响，同时降低电子设备的防水难度。
需要说明的是，由于第一电容片31设置在激励器和壳体1之间，使得第一电容片31和壳体1远离陶瓷扬声器2的表面组成可变电容单元。当操作者的手按压或者触摸壳体1远离陶瓷扬声器2的表面时，由于人手带电，且随着操作者的手的按压会改变激励器与壳体1的谐振点，引起可变电容单元的发生变化。此外，检测芯片33和第一电容片31电连接，进而可以通过检测芯片33实时获取可变电容单元的实时电容值。检测芯片33可以内置于处理器4，也可以外置于处理器4。还需要说明的是，在本发明实施例中，第一电容片31可以为导电膜片，也可以为金属薄膜传感器，或者其它可以导电且能形成可变电容单元的薄膜片，本发明实施例对此不做限定。
第二电容片32设置在激励器远离壳体1的一端，检测芯片33分别与第一电容片31和第二电容片32电连接，第一电容片31和第二电容片32组成可变电容单元。在本发明实施例中，第二电容片32和第一电容片31的类型相同，本发明实施例对此不做赘述，由于第二电容片32设置在激励器远离壳体1的一端，第一电容片31和第二电容片32组成可变电容单元，可以将第二电容片32接地。由于第一电容片31和第二电容片32之间的距离不变，进而当操作者的手握住或者按压电子设备的壳体1时，使得第一电容片31上的单极电容发生变化，又由于第二电容片32接地，使得第二电容片32上的单 极电容为0，进而在检测时，只需要检测第二电容片32上的单极电容即可以反映实时电容值。此外，第二电容片32可以为金属薄膜，可以屏蔽远离电子设备壳体1一侧的电容干扰，避免对可变电容单元检测的电容造成影响，进而使得检测的精度更高。
此外，驱动器5可以为功率放大器的一种，驱动器5可以外置于陶瓷扬声器2，也可以内置于陶瓷扬声器2，用于提高陶瓷扬声器2的输出功率。功率放大器可以为电荷泵型放大器或者升压型放大器的一种。驱动器5分别与处理器4和激励器电连接，处理器4和检测芯片33电连接，进而使得驱动器5可以通过改变激励器的振动来改变陶瓷扬声器2的输出功率。这样，使得处理器4可以处理检测芯片33获取到的可变电容单元实时电容值，也能根据实时电容值控制驱动器5进行提高陶瓷扬声器2的输出功率，进而达到调节陶瓷扬声器2的输出音量的作用。
在本发明实施例提供的电子设备中，由于电容检测组件3包括第一电容片31、第二电容片32和检测芯片33，第一电容片31设置连接激励器和壳体1之间，第二电容片32连接在激励器的远离壳体1的一侧，检测芯片33分别与第一电容片31和第二电容片32电连接，第一电容片31和第二电容片32组成可变电容单元，可变电容单元的电容值随壳体1的形变而发生变化，检测芯片33用于获取可变电容单元的实时电容值，因此，当电子设备的壳体1被操作者的手握住或者按压住时，检测芯片33可以随时检测可变电容单元的实时电容值的变化；又由于处理器4分别与驱动器5和电容检测组件3电连接，驱动器5和激励器电连接，因此，处理器4可以根据实时电容值控制驱动器5调节所述陶瓷扬声器2的输出音量，进而使陶瓷扬声器2的音量不受操作者的手握住或者按压影响。
可选的，处理器4根据实时电容值控制陶瓷扬声器2的输出音量，包括：
处理器4根据实时电容值和门限电容值，确定陶瓷扬声器2的实时补偿值，其中，门限电容值为在壳体1未发生形变的情况下电容检测组件3获取的电容值；
驱动器5基于陶瓷扬声器2的实时补偿值，调节陶瓷扬声器2的输出功率，以调节陶瓷扬声器2的输出音量。
在本发明实施例中，由于第一电容片31和第二电容片32组成可变电容单元，可变电容单元的电容值随壳体1的形变而发生变化，检测芯片33用于获取可变电容单元的实时电容值，因此，当操作者的手按压或者触摸壳体1远离陶瓷扬声器2的表面时，由于人手带电，且随着操作者的手的按压会改变激励器与壳体1的谐振点，引起可变电容单元的发生变化。此外，检测芯片33可以内置在处理器4中，也可以外置在处理器4中，检测芯片33和第一电容片31和第二电容片32电连接，进而可以通过检测芯片33实时获取第一电容片31和第二电容片32组成的可变电容单元的实时电容值。
需要说明的是，门限电容值为壳体1未发生形变的情况下电容检测组件3获取的电容值，门限电容值可以,根据激励器在操作者的手未按压或者未触摸壳体1远离陶瓷扬声器2的表面时，激励器处于和壳体1正常谐振点时，电容检测组件3检测到的可变电容单元的电容值。
在本发明实施例中，当处理器4获取到实时电容值和门限电容值后，可以对实时电容值和门限电容值进行处理，根据但不限于实时电容值和门限电容值的关系，确定陶瓷扬声器2的实时补偿值。示例性的，当获取到的实时电容值等于或者小于门限电容值，则可以确定陶瓷扬声器2处于正常发声状态，即陶瓷扬声器2发出的音量为操作者的耳朵能够听到的音量，则可以确定陶瓷扬声器2的实时补偿值为0，即陶瓷扬声器2不需要进行补偿。若获取到的实时电容值大于门限电容值，则可以确定陶瓷扬声器2处于非正常发声状态，即操作者的手按压或者触摸壳体1远离陶瓷扬声器2的表面，改变了激励器与壳体1的谐振点，使得陶瓷扬声器2的音量降低，则需要对陶瓷扬声器2的音量进行补偿，使得人耳能够听到。
之后，由于只有在操作者的手按压或者触摸壳体1远离陶瓷扬声器2的表面，改变了激励器的谐振点的状态下，才需要对陶瓷扬声器2的进行音量补偿，因此，当确定了陶瓷扬声器2的实时补偿值后，生成的音量增益指令均为使得陶瓷扬声器2音量增加的指令。该音量增益指令为触发驱动器5进行功率放大的指令。
当生成了音量增益指令后，可以将音量增益指令发给驱动器5，由于音量增益指令为触发驱动器5进行功率放大的指令，进而在驱动器5接收到音 量增益指令后，可以调节陶瓷扬声器2的输出功率，以调节陶瓷扬声器2的输出音量。
这样，通过处理器4根据实时电容值和门限电容值，确定陶瓷扬声器2的实时补偿值，其中，门限电容值为在壳体1未发生形变的情况下电容检测组件3获取的电容值；之后，驱动器5基于陶瓷扬声器2的实时补偿值，调节陶瓷扬声器2的输出功率，使得陶瓷扬声器2的音量得到提高，进而在电子设备壳体1被操作者的手握住或者按压电子设备的壳体1时，也不会对陶瓷扬声器2的音量造成影响。
可选的，处理器4用于：根据实时电容值和门限电容值，确定实时电容差值；
根据实时电容差值，确定陶瓷扬声器2的实时补偿值。
在本发明实施例中，当实时电容差值为正值时，则表示获取到的实时电容值大于门限电容值，则可以确定陶瓷扬声器2处于非正常发声状态，即操作者的手按压或者触摸壳体1远离陶瓷扬声器2的表面，改变了激励器与壳体1的谐振点，使得陶瓷扬声器2的音量降低，则需要对陶瓷扬声器2的音量进行补偿，使得人耳能够听到。当实施电容值为小于或者等于0时，则表示获取到的实时电容值等于或者小于门限电容值，则可以确定陶瓷扬声器2处于正常发声状态，即陶瓷扬声器2发出的音量为操作者的耳朵能够听到的音量，则可以确定陶瓷扬声器2的实时补偿值为0，即陶瓷扬声器2不需要进行补偿。
可选的，处理器4用于：获取预设电容值范围和预设补偿值；基于预设电容值范围和预设补偿值，生成预设电容值范围和预设补偿值之间的对应关系；基于实时电容差值和对应关系，确定陶瓷扬声器2的实时补偿值。
在本发明实施例中，可以根据人耳能够听到的正常音量，在处理器4内存储预设电容值范围和预设补偿值。预设补偿值可以根据驱动器5的类型确定。在获取预设电容值范围和预设补偿值后，可以生成预设电容值范围和预设补偿值之间的对应关系，可以将生成的预设电容值范围和预设补偿值之间的对应关系存储在处理器4中。该对应关系可以为一一映射关系。表1是预 设电容值范围和预设补偿值的对应关系表，例如表1所示：
表1
预设电容值范围(F) 预设补偿值(dB)
(0,5] 1.5
(5,10] 3
(10,15] 4.5
＞15 6
当电容值为大于0F且小于或者等于5F时，对应的预设补偿值为1.5dB，当电容值为大于5F且小于或者等于10F时，对应的预设补偿值为3dB，当电容值为大于10F且小于或者等于15F时，对应的预设补偿值为4.5dB，当电容值大于15F时，对应的预设补偿值为6dB。上述实施例仅为一种示例，具体数值依据陶瓷扬声器2的类型确定。当需要确定陶瓷扬声器2的实时补偿值时，可以获取预先存储的预设电容值范围和预设补偿值之间的对应关系和实时电容差值，确定陶瓷扬声器2的实时补偿值。
可选的，处理器4用于：
若实时电容差值小于或者等于0，确定陶瓷扬声的补偿值为0；

若实时电容差值位于第三预设电容值范围，确定陶瓷扬声的补偿值为第三补偿值；
若实时电容差值位于第四预设电容值范围，确定陶瓷扬声的补偿值为第四补偿值，其中，第二补偿值大于第一补偿值，第三补偿值大于第二补偿值，第四补偿值大于第三补偿值。
在本发明实施例中，当生成预设电容值范围和补偿值之间的对应关系后，由于该对应关系可以为一一映射关系，因此，任何一个实时电容值均可以对应一个预设补偿值。若预设电容值范围和预设补偿值的对应关系为表1所示的关系，示例性的，若获取到的实时电容值为13F，可以确定实时电容值位 于(10,15]的预设电容值范围，则根据对应关系，则可以确定陶瓷扬声的补偿值为4.5dB。
需要说明的是，第一预设电容值范围、第二预设电容值范围、第三预设电容值范围、第四预设电容值范围可以为相等的几个电容值区间，也可以为不等的几个电容值区间。此外，在一种可能实现的方式中，第二补偿值可以等于2倍的第一补偿值、第三补偿值可以等于3倍的第一补偿值、第四补偿值可以等于4倍的第一补偿值，在另一种可能实现的方式中，第一补偿值、第二补偿值、第三补偿值、第四补偿值可以为没有任何倍数关系的值。
需要说明的是，由于预设电容值范围可以分为第一预设电容值范围、第二预设电容值范围、第三预设电容值范围和第四预设电容值范围，因此，使得预设电容值范围的划分更为细致，使得实时电容值和陶瓷扬声器2的实时补偿值的对应关系更为明确，避免因预设电容值范围过大导致对应的实时补偿值较为单一，不会对陶瓷扬声器2的音量的补偿效果造成影响。
在本发明实施例提供的电子设备中，由于电容检测组件3包括第一电容片31、第二电容片32和检测芯片33，第一电容片31设置连接激励器和壳体1之间，第二电容片32连接在激励器的远离壳体1的一侧，检测芯片33分别与第一电容片31和第二电容片32电连接，第一电容片31和第二电容片32组成可变电容单元，可变电容单元的电容值随壳体1的形变而发生变化，检测芯片33用于获取可变电容单元的实时电容值，因此，当电子设备的壳体1被操作者的手握住或者按压住时，检测芯片33可以随时检测可变电容单元的实时电容值的变化；又由于处理器4分别与驱动器5和电容检测组件3电连接，驱动器5和激励器电连接，因此，处理器4可以根据实时电容值控制驱动器5调节所述陶瓷扬声器2的输出音量，进而使陶瓷扬声器2的音量不受操作者的手握住或者按压影响。
此外，由于预设电容值范围可以分为第一预设电容值范围、第二预设电容值范围、第三预设电容值范围和第四预设电容值范围，因此，使得预设电容值范围的划分更为细致，使得实时电容值和陶瓷扬声器2的实时补偿值的对应关系更为明确，避免因预设电容值范围过大导致对应的实时补偿值较为单一，不会对陶瓷扬声器2的音量的补偿效果造成影响。
参见图2，本发明实施例二还提供了一种陶瓷扬声器2的音量调节方法，应用于本发明实施例一的电子设备，该音量调节方法包括：

基于陶瓷扬声器2的实时补偿值，调节陶瓷扬声器2的输出功率，以调节陶瓷扬声器2的输出音量。
在本发明实施例中，由于第一电容片31和第二电容片32组成可变电容单元，可变电容单元的电容值随壳体1的形变而发生变化，检测芯片33用于获取可变电容单元的实时电容值，因此，当操作者的手按压或者触摸壳体1远离陶瓷扬声器2的表面时，由于人手带电，且随着操作者的手的按压会改变激励器与壳体1的谐振点，引起可变电容单元的发生变化。此外，检测芯片33可以内置在处理器4中，也可以外置在处理器4中，检测芯片33和第一电容片31电连接，进而可以通过检测芯片33实时获取可变电容单元的实时电容值。
需要说明的是，门限电容值为壳体1未发生形变的情况下电容检测组件3获取的电容值，门限电容值可以,根据激励器在操作者的手未按压或者未触摸壳体1远离陶瓷扬声器2的表面时，激励器处于和壳体1正常谐振点时，电容检测组件3检测到的可变电容单元的电容值。
在本发明实施例中，当处理器4获取到实时电容值和门限电容值后，可以对实时电容值和门限电容值进行处理，根据但不限于实时电容值和门限电容值的关系，确定陶瓷扬声器2的实时补偿值。示例性的，当获取到的实时电容值等于或者小于门限电容值，则可以确定陶瓷扬声器2处于正常发声状态，即陶瓷扬声器2发出的音量为操作者的耳朵能够听到的音量，则可以确定陶瓷扬声器2的实时补偿值为0，即陶瓷扬声器2不需要进行补偿。若获取到的实时电容值大于门限电容值，则可以确定陶瓷扬声器2处于非正常发声状态，即操作者的手按压或者触摸壳体1远离陶瓷扬声器2的表面，改变了激励器与壳体1的谐振点，使得陶瓷扬声器2的音量降低，则需要对陶瓷 扬声器2的音量进行补偿，使得人耳能够听到。
之后，由于只有在操作者的手按压或者触摸壳体1远离陶瓷扬声器2的表面，改变了激励器的谐振点的状态下，才需要对陶瓷扬声器2的进行音量补偿，因此，当确定了陶瓷扬声器2的实时补偿值后，生成的音量增益指令均为使得陶瓷扬声器2音量增加的指令。该音量增益指令为触发驱动器5进行功率放大的指令。
当生成了音量增益指令后，可以将音量增益指令发给驱动器5，由于音量增益指令为触发驱动器5进行功率放大的指令，进而在驱动器5接收到音量增益指令后，可以调节陶瓷扬声器2的输出功率，以调节陶瓷扬声器2的输出音量。
这样，处理器4可以根据电容检测组件3获取的实时电容值，确定陶瓷扬声器2的实时补偿值，之后，驱动器5基于陶瓷扬声器2的实时补偿值，调节陶瓷扬声器2的输出功率，使得陶瓷扬声器2的音量得到提高，进而在电子设备的壳体1被操作者的手握住或者按压电子设备的壳体1时，也不会对陶瓷扬声器2的音量造成影响。
在本发明实施例提供的音量调节方法中，由于该电子设备可以根据实时电容值控制驱动器5调节陶瓷扬声器2的输出音量，因此，当电子设备的壳体1被操作者的手握住或者按压住时，通过电子设备包括的电容检测组件3可以随时检测可变电容单元的实时电容值的变化；之后，该电子设备包括的处理器4可以根据实时电容值控制驱动器5调节所述陶瓷扬声器2的输出音量，进而使陶瓷扬声器2的音量不受操作者的手握住或者按压影响。
