This structure with the insulating layer 63 and the cavity 630 is more conducive to the vibration of the piezoelectric vibrating layer 60 and the emission of stronger sound waves.
于本发明较佳实施例中，所述压电振动层60可包括一个或者多个输出位置。在包括一个输出位置的方案中，工艺简单，成本更低。在包括多个输出位置的方案中，多个输出位置的结构，发声效果更佳优异。In a preferred embodiment of the present invention, the piezoelectric vibrating layer 60 may include one or more output positions. In the scheme including one output location, the process is simple and the cost is lower. In a solution that includes multiple output positions, the structure of multiple output positions has a better sound effect.
下面以三个输出位置为例，对压电振动层60的平面结构进行阐述。The following describes the planar structure of the piezoelectric vibration layer 60 by taking three output positions as an example.
图8为压电振动层60的平面结构示意图。所述压电振动层60包括多个振动器65（压电激励器），多个垂直隔音部64v、以及多个水平隔音部64h。FIG. 8 is a schematic diagram of the planar structure of the piezoelectric vibration layer 60. The piezoelectric vibration layer 60 includes a plurality of vibrators 65 (piezoelectric actuators), a plurality of vertical sound insulation parts 64v, and a plurality of horizontal sound insulation parts 64h.
所述多个振动器65（压电激励器）设置在压电振动层60内。其中左右两颗所述振动器65（压电激励器）用于产生高音，而中间的所述振动器65（压电激励器）用于产生低音，从而改善了单颗振动器65（压电激励器）的低频效果差的问题。The plurality of vibrators 65 (piezoelectric actuators) are provided in the piezoelectric vibration layer 60. Among them, the left and right two vibrators 65 (piezoelectric actuators) are used to produce high pitch, and the middle vibrator 65 (piezoelectric actuators) is used to produce bass, thus improving the single vibrator 65 (piezoelectric actuator). The low frequency effect of the exciter) is poor.
所述多个垂直隔音部64v相间隔设置以使各振动器65（压电激励器）分别设置在两相邻的垂直隔音部64v之间，从而消除了相互之间的声音干扰，实现了立体声，提高了音质和用户体验。更进一步，设置在最左边和最右边的垂直隔音部64v1、4，这样可防止产生的声波从侧边传出，从而发生声音的泄露，并且可减少音量的损失，提高输出的音量。The plurality of vertical sound insulation parts 64v are arranged at intervals so that each vibrator 65 (piezoelectric actuator) is respectively arranged between two adjacent vertical sound insulation parts 64v, thereby eliminating mutual sound interference and achieving stereo sound , Improve the sound quality and user experience. Furthermore, the vertical sound insulation parts 64v1 and 4 are arranged on the leftmost and rightmost sides, which can prevent the sound waves generated from being transmitted from the side, thereby causing sound leakage, and can reduce the volume loss and increase the output volume.
所述多个水平隔音部64h分别设置在所述多个振动器65（压电激励器）下方，各水平隔音部64h分别设置在两相邻的垂直隔音部64v之间，使得声音无法从下方泄露传出，减少音量的损失，提高输出的音量。The plurality of horizontal sound insulation parts 64h are respectively disposed below the plurality of vibrators 65 (piezoelectric actuators), and each horizontal sound insulation part 64h is respectively disposed between two adjacent vertical sound insulation parts 64v, so that sound cannot be heard from below. Leak out, reduce the loss of volume, and increase the output volume.
图9为垂直隔音部64v或水平隔音部64h的侧面剖视图。可通过调节所述垂直隔音部64v和所述水平隔音部64h的高度H和宽度W来调节隔音的效果，以及输出的音量。首先，所述隔音部在未压缩状态下的高度是大于所述振动器65（压电激励器）与主板之间的间距，从而实现了良好的密封效果。当所述垂直隔音部64v和所述水平隔音部64h高度越高时，那么被压缩的程度越大，从而实现了更好的密封效果。但是，当所述垂直隔音部64v和所述水平隔音部64h高度H太大，会影响声音的输出，输出的音量较小。Fig. 9 is a side cross-sectional view of the vertical soundproof portion 64v or the horizontal soundproof portion 64h. The sound insulation effect and the output volume can be adjusted by adjusting the height H and width W of the vertical sound insulation part 64v and the horizontal sound insulation part 64h. First, the height of the sound insulation part in the uncompressed state is greater than the distance between the vibrator 65 (piezoelectric actuator) and the main board, thereby achieving a good sealing effect. When the height of the vertical sound insulation portion 64v and the horizontal sound insulation portion 64h is higher, the degree of compression is greater, thereby achieving a better sealing effect. However, when the height H of the vertical sound insulation portion 64v and the horizontal sound insulation portion 64h is too large, the sound output will be affected, and the output volume will be low.
另外，宽度W也是类似高度H的原理。当宽度W越大，可供振动的范围越小，从而隔音效果就更好，但是输出的音量就更小。通常所述垂直隔音部64v和所述水平隔音部64h高度H为1-100mm，宽度W为1-50mm。可根据所需要的音质和音量选择最佳的高度H和宽度W的参数。In addition, the width W is similar to the principle of the height H. When the width W is larger, the available vibration range is smaller, so the sound insulation effect is better, but the output volume is smaller. Generally, the height H of the vertical sound insulation part 64v and the horizontal sound insulation part 64h is 1-100 mm, and the width W is 1-50 mm. The optimal height H and width W parameters can be selected according to the required sound quality and volume.
