It can be understood that the first sound-conducting channel 106 may form a front cavity of the sound-generating device 104, that is, the first diaphragm of the sound-generating device 104 faces the display module 101. Correspondingly, the second sound-conducting channel 108 may form a rear cavity of the sound-generating device 104.

- the leakage part of the first sound wave signal can be opposite to the phase of the second sound wave signal transmitted from the second sound outlet 107, so that the leakage part of the first sound wave signal and the second sound wave signal form an acoustic dipole, so that the leakage part of the first sound wave signal and the second sound wave signal cancel each other out, thereby preventing the problem of sound leakage during the user's call.
- the embodiment of the present disclosure simultaneously opens the first sound outlet 105 and the second sound outlet 107, thereby forming two sound sources on the surface of the electronic device.

- the second diaphragm 1091 can transmit the acoustic signal in the sub-sound cavity to the sub-sound guide channel, it can ensure that the acoustic device in the second sound guide channel 108 can be transmitted to the outside world through the second sound outlet 107.
- the vibration plate 1092 can increase the vibration amplitude of the diaphragm, thereby facilitating the increase of the acoustic signal.
- the signal strength will be enhanced, that is, the acoustic signal emitted from the second sound outlet 107 will be enhanced, which is conducive to balancing the energy of the sound waves emitted by the first sound outlet 105 and the second sound outlet 107 , thereby improving the sound leakage prevention effect.

- the sound wave enhancement component 109 can resonate with most of the acoustic signals output by the sound device 104, and when the sound device 104 resonates with the sound wave, the sound wave enhancement component 109 can further increase the amplification of the sound wave, which is conducive to further balancing the energy of the sound waves emitted by the first sound outlet 105 and the second sound outlet 107, thereby improving the sound leakage prevention effect.
- the electronic device also includes a mainboard bracket 118 and a sealing plate 117, the mainboard bracket 118 and the sealing plate 117 are arranged opposite to each other, the mainboard bracket 118 is connected to the frame 102, the sealing plate 117 is connected to the shell 103, and the second sound guide channel 108 is formed between the mainboard bracket 118 and the sealing plate 117.

- the first dustproof net can reduce foreign matter entering the electronic device from the first sound outlet 105 to a certain extent, it is beneficial to further improve the overall waterproof and dustproof performance of the electronic device.
- a first sound wave signal emitted from the first sound outlet 105 and a second sound wave signal emitted from the second sound outlet 107 form an acoustic dipole.
- the acoustic signal in the second sound guide channel 108 is enhanced by the sound wave enhancement component 109, and the enhancement amplitude of the acoustic signal in the second sound guide channel 108 by the sound wave enhancement component 109 can be adjusted by changing the structure of the sound wave enhancement component 109, for example, changing the size of the vibration plate 1092.
- the energy of the sound wave emitted by the first sound outlet 105 can be equal to the energy of the sound wave emitted by the second sound outlet 107, so that the first sound wave signal emitted by the first sound outlet 105 and the second sound wave signal emitted from the second sound outlet 107 form an acoustic dipole, so that the first sound wave signal and the second sound wave signal can cancel each other in the far field, thereby preventing the problem of sound leakage in the electronic device.
- the electronic device further includes a decorative cover 111 , which is connected to the frame 102 and located between the sound-emitting device 104 and the display module 101 , and is opposite to the first sound outlet 105 to reduce the sound outlet area of the first sound outlet 105 .
- the sound waves emitted by the first sound outlet 105 The energy of the energy center is greater than the energy of the anti-phase sound wave emitted by the second sound outlet 107 , which limits the effect of preventing sound leakage.
- the decorative cover 111 is opposite to the first sound outlet 105 to reduce the sound outlet area of the first sound outlet 105. Since the sound outlet area of the first sound outlet 105 is reduced, the energy of the sound wave energy center emitted by the first sound outlet 105 of the electronic device can be effectively reduced, which is conducive to balancing the energy of the sound waves emitted by the first sound outlet 105 and the second sound outlet 107, thereby improving the sound leakage prevention effect.
- the first sound outlet 105 includes a strip-shaped slit, the strip-shaped slit includes a first segment and a second segment, and the distance between the first segment and the sound-generating device 104 is smaller than the distance between the second segment and the sound-generating device 104;
- the decorative cover 111 and the first segment are used to cover the first segment of the strip-shaped seam.
- the decorative cover 111 blocks the first segment of the strip seam, and the first segment of the strip seam is an opening on the surface of the electronic device, in order to prevent the decorative cover 111 from affecting the appearance of the electronic device, the decorative cover 111 can be made of a transparent material, and the decorative cover 111 can be pasted on the inner side of the strip seam.
- the first sound wave signal needs to propagate in the direction indicated by the arrow in Figure 3. That is, the first sound wave signal cannot propagate outward when it propagates to the first segment of the strip slit, and needs to bypass the first segment to propagate to the outside from the opening of the second segment. This is conducive to extending the length of the first sound guide channel 106, thereby further reducing the energy of the first sound wave signal emitted from the first sound outlet 105, so as to further balance the energy of the sound waves emitted by the first sound outlet 105 and the second sound outlet 107, thereby improving the sound leakage prevention effect.
- the orthographic projection of the sound-emitting device 104 in the display module 101 is relatively staggered from the position of the first sound outlet 105 .

- the second sound outlet 107 is formed by a gap between the shell 103 and the shooting module 220.
- the shooting module 220 can block the second sound outlet 107 to a certain extent, thereby avoiding the problem of reduced overall aesthetics of the electronic device due to the second sound outlet 107 being opened in a relatively conspicuous position in the shell 103, which is beneficial to improving the overall aesthetics of the electronic device.

所述声波增强组件109位于所述发声器件104与所述壳体103之间，且所述声波增强组件109与所述发声器件104密封连接，所述声波增强组件109将所述第二导音通道108分隔为：位于所述发声器件104与所述声波增强组件109之间的子音腔，以及，位于所述声波增强组件109与所第二出音口107之间的子导音通道。
本公开实施例中，由于所述第一出音口105位于所述电子设备的前端，因此，所述第
一出音口105形成所述发声器件104的出音口，具体地，所述第一出音口105为形成于所述显示模组101与框体102之间的出音缝，或者，所述第一出音口105为开设于所述显示模组101的出音孔。
上述第二出音口107可以是开设于所述壳体103的各种形状的开口，例如，可以是出音孔或出音缝等形式的开口。此外，上述第一导音通道106和第二导音通道108可以是由所述电子设备内部的各种器件之间的间隙所形成的导音通道。例如，请参见图1，在本公开一个实施例中，所述第一导音通道106由第一密封件、第三防尘网112、装饰罩111、框体102、显示模组101等器件之间的间隙共同形成。请参见图2，所述第二导音通道108由第二密封件、用于支撑主板113的主板支架118、密封钢板、壳体103和装饰件119等器件之间的间隙共同形成。
上述发声器件104可以是电子设备中常见的声学器件，可以理解的是，所述第一导音通道106可以形成所述发声器件104的前腔，即所述发声器件104的第一振膜朝向所述显示模组101。相应地，所述第二导音通道108可以形成所述发声器件104的后腔。在所述声学器件处于工作状态下，所述发声器件104发射的声波可以分别传播至第一导音通道106和第二导音通道108，并分别通过第一出音口105和第二出音口107传播至电子设备外。
然而，由于电子设备整机前部的第一出音口105是常规方案所具备的特征，所以开孔面积往往会比较充裕，相应的前部导音通道的尺寸也往往较为理想。而所述背部的第二出音口107并非常规开孔，往往需要做到比较隐蔽或足够小，而且具体的开孔位置也会受到限制，以避免出现对整机外观效果的影响。所以背部开口往往比较小、距离发声器件104比较远，因此，所述第一导音通道106的通气性高于所述第二导音通道108的通气性。这样，将导致第一出音口105发出的声波能量中心的能量大小大于第二出音口107发出的反相声波的能量大小，进而导致第二出音口107发出第二声波信号无法完全抵消第一出音口105发出声波信息，从而限制了防漏音的效果。
基于此，本公开实施例中，通过在发声器件104与所述壳体103之间设置声波增强组件109，这样，声波增强组件109可以对第二导音通道108内的声波信号进行增强，使得从第一出音口105发出的声波信号与第二出音口107发出的声波信号相对平衡，如此，从第一出音口105发出的第一声波信号与第二出音口107发出的第二声波信号可以形成声偶极子，第一声波信号和第二声波信号在远场可以相互抵消，从而防止电子设备出现声音泄露的问题。
其中，所述声波增强组件109可以是能够对子音腔中的声波信号进行增强的器件，且由于所述声波增强组件109将所述第二导音通道108分隔为子音腔和子导音通道，因此，所述子音腔中的声波信号在经过声波增强组件109进行增强之后，可以通过所述声波增强组件109传递至所述子导音通道，以确保所述第二导音通道108内的声波信号可以传播至电子设备外。
具体地，由于第一出音口105和第二出音口107分别位于电子设备的前后两端，因此，所述第一出音口105和第二出音口107可以分别形成电子设备上的两个不同声源。请参见图5，在用户在手持电子设备通话场景下，由于第一出音口105通常贴合于用户的耳部，因此，从第一出音口105传播出的第一声波信号一部分进入人耳，另一部分会通过人体反射朝电子设备的背面一侧传播(如图5箭头所指示的方向)，所述第一声波信号的泄露部分可以与从所述第二出音口107传出的第二声波信号的相位相反，使得所述第一声波信号的泄露部分与所述第二声波信号形成声偶极子，以实现第一声波信号的泄露部分与所述第二声波信号相互抵消，从而防止用户通话过程中出现声音泄露的问题。此外，相对于仅开设第一出音口105而言，本公开实施例通过同时开设第一出音口105和第二出音口107，从而在电子设备的表面形成两个声源，因此，用户所能够听到的声音更为清楚，从而实现近场的声波信号加强的效果。
该实施方式中，通过在发声器件104与所述壳体103之间设置声波增强组件109，这样，声波增强组件109可以对第二导音通道108内的声波信号进行增强，使得从第一出音口105发出的声波信号与第二出音口107发出的声波信号相对平衡，如此，从第一出音口105发出的第一声波信号与第二出音口107发出的第二声波信号可以形成声偶极子，第一声波信号和第二声波信号在远场可以相互抵消，从而防止电子设备出现声音泄露的问题。此外，由于声波增强组件109将第二导音通道108分隔为子音腔和子导音通道，因此，外界的污染物无法通过第二出音口107进入所述发声器件104，从而有利于提高电子设备整体的防水、防尘性能。
可选地，所述声波增强组件109包括第二振膜1091和振动板1092，所述第二振膜1091与所述发声器件104间隔设置，且所述第二振膜1091通过第一环形密封件115与所述发声器件104朝向所述壳体103一端的端面密封连接，所述发声器件104、所述第一环形密封件115和所述第二振膜1091共同围合形成所述子音腔；所述振动板1092与所述第二振膜1091贴合连接。
其中，所述第一环形密封件115可以为环形塑胶圈、环形橡胶。通过采用第一环形密封件115实现第二振膜1091与发声器件104之间连接，从而可以在所述第二振膜1091与发声器件104之间形成密封的子音腔。
具体地，通过采用第二振膜1091将所述第二导音通道108分隔为子音腔和子导音通道，如此，由于第二振膜1091可以将发声器件104与第二出音口107相对隔开，避免外界物质通过第二出音口107进入发声器件104，从而有利于提高电子设备整体的防水、防尘性能。此外，由于第二振膜1091可以将子音腔内的声学信号传递至子导音通道，因此，可以确保第二导音通道108内的声学器件可以通过第二出音口107传播至外界。
此外，通过在所述第二振膜1091上增设振动板1092，如此，在声波信号传递至振动板1092，导致振动板1092振动过程中，振动板1092可以增大所述振膜的振动幅度，从而有利于增大声学信号。如此，发生器件传递至子音腔的第二声学信号在经过第二振膜
1091之后，信号强度将增强，即从所述第二出音口107发出的声学信号将增强，从而有利于平衡第一出音口105与第二出音口107发出的声波的能量大小，进而提高防漏音效果。
可选地，在所述发声器件104传递至所述子音腔的声波信号的频率位于预设范围内的情况下，所述声波增强组件109与所述声波信号产生共振，所述发声器件104的工作频段包括所述预设范围。
其中，所述预设范围可以与所述发声器件104所输出的声学信号的范围相匹配，例如，当所述发声器件104所输出的声学信号大部分位于中低频或低频范围时，所述预设范围也可以相应为中低频或低频范围。如此，所述声波增强组件109可以与所述发声器件104所输出的大部分声学信号产生共振，而当发声器件104与声波产生共振时，声波增强组件109对声波的放大幅度可以进一步增大，从而有利于进一步平衡第一出音口105与第二出音口107发出的声波的能量大小，进而提高防漏音效果。
可选地，所述电子设备还包括主板支架118和密封板117，所述主板支架118与所述密封板117相对设置，所述主板支架118与所述框体102连接，所述密封板117与所述壳体103连接，且所述第二导音通道108形成于所述主板支架118与所述密封板117之间。
该实施方式中，所述主板支架118与所述密封板117可以分别形成所述第二导音通道108两个相对的内侧壁，如此，可以通过所述主板支架118和密封板117将所述第二导音通道108与电子设备中的其他器件进一步隔开，从而有利于进一步提高电子设备整体的防水、防尘性能。
可选地，所述第二出音口107内设有第一防尘网。
该实施方式中，通过在第二出音口107处设置第一防尘网，由于第一防尘网在一定程度上可以减少外界物质从第一出音口105进入电子设备内部，因此，有利于进一步提高电子设备整体的防水防尘性能。
可选地，在所述发声器件104发射声波的情况下，从所述第一出音口105发出的第一声波信号与从所述第二出音口107发出的第二声波信号形成声偶极子。
该实施方式中，通过所述声波增强组件109对第二导音通道108内的声学信号进行增强，并可以通过改变声波增强组件109的结构，例如，改变振动板1092的大小，以调节声波增强组件109对第二导音通道108中的声学信号的增强幅度。如此，可以实现所述第一出音口105发出的声波的能量大小等于第二出音口107发出的声波的能量大小，从而使得所述第一出音口105发出的第一声波信号与从所述第二出音口107发出的第二声波信号形成声偶极子，如此，第一声波信号和第二声波信号在远场可以相互抵消，从而防止电子设备出现声音泄露的问题。
可选地，所述电子设备还包括装饰罩111，所述装饰罩111与所述框体102连接，且所述装饰罩111位于所述发声器件104与所述显示模组101之间，所述装饰罩111与所述第一出音口105相对，以减小所述第一出音口105的出音面积。
由上述实施例可知，由于电子设备的结构限制，从而导致第一出音口105发出的声波
能量中心的能量大小大于第二出音口107发出的反相声波的能量大小，限制了防漏音的效果。
基于此，请参见图1和图3，本公开实施例中，通过所述装饰罩111与所述第一出音口105相对，以减小所述第一出音口105的出音面积。由于所述第一出音口105的出音面积减小，因此，可以有效的减小电子设备第一出音口105发出的声波能量中心的能量大小，从而有利于平衡第一出音口105与第二出音口107发出的声波的能量大小，进而提高防漏音效果。
可选地，所述第一出音口105包括条形缝，所述条形缝包括第一分段和第二分段，所述第一分段与所述发声器件104之间的距离小于所述第二分段与所述发声器件104之间的距离；
所述装饰罩111与所述第一分段，以遮挡所述条形缝的所述第一分段。
其中，由于装饰罩111遮挡所述条形缝的第一分段，而条形缝的第一分段为电子设备表面的开口，为避免装饰罩111影响电子设备的美观，因此，所述装饰罩111可以采用透明材质的装饰罩111，且所述装饰罩111可以粘贴于所述条形缝的内侧。
请参见图3，在本公开实施例中，所述第一声波信号需要沿图3中箭头所指示的方向进行传播。即第一声波信号在传播至条形缝的第一分段时并无法向外传播，需要绕过第一分段才能从第二分段的开口处传播至外界，如此，有利于延长第一导音通道106的长度，进而进一步减小从第一出音口105发出的第一声波信号的能量大小，以进一步平衡第一出音口105与第二出音口107发出的声波的能量大小，进而提高防漏音效果。
可选地，所述发声器件104在所述显示模组101中的正投影与所述第一出音口105的位置相对错开。
该实施方式中，通过使所述发声器件104在所述显示模组101中的正投影与所述第一出音口105的位置相对错开，这样，有利于延长第一导音通道106的长度，以进一步平衡第一出音口105与第二出音口107发出的声波的能量大小，进而提高防漏音效果。
可选地，所述电子设备包括拍摄模组220，所述壳体103上开设有安装孔，所述拍摄模组220穿设于所述安装孔内，所述壳体103与所述拍摄模组220之间的间隙形成所述第二出音口107。
该实施方式中，通过使所述壳体103与所述拍摄模组220之间的间隙形成所述第二出音口107，如此，由于拍摄模组220在一定程度上可以遮挡所述第二出音口107，从而避免了因第二出音口107开设于壳体103中相对显眼的位置，而导致电子设备整体美观性降低的问题，从而有利于提高电子设备整体的美观性。
