一种内嵌于油画或画布中的高音质音响系统 技术领域
本实用新型涉及油画、印刷品、帆布画等艺术装饰品的技术领域，尤其涉及一种内嵌于油画或画布中的高音质音响系统。
 背景技术
市场上已有可以让油画产生音频的装置，但音质很差。现有的此类装置，借助一个或多个音频激励器结合振动的刚性屏幕来发生声音，这种音频激励器通常是磁动力音频激励器。市场上已经出现了通过声激励器引起前部振动的油画、艺术、摄影复制品等装饰品的扬声器，及可以挂在墙上、类似几何形状的传统音频扬声器，这些扬声器称为“壁挂扬声器”。
从音频质量和设计的角度来看，现有技术的解决方案明显损害了系统的声学性能。此外，现有技术的各种设备昂贵且安装复杂。
参见申请号为200610093003 .X的机电转换设备，该机电转换设备公开了磁力控制激励器，该磁力控制激励器包括：磁力控制元件；布置在所述磁力控制元件周围的螺线管线圈；连接于所述磁力控制元件的端部的驱动元件；以及包含所述磁力控制元件和所述螺线管线圈的外壳，所述外壳由支撑盘、永磁体和管形壳体构成，其中，所述支撑盘和所述管形壳体由铁磁体材料制成，并且在所述驱动元件和所述外壳之间有空隙。
本实用新型提供了一种内嵌于油画或画布中的高音质音响系统，具有音质效果好、组件成本较低、制造复杂程度降低及稳定性较好等特点。
为了解决上述技术问题，本实用新型所采取的技术方案为：
一种内嵌于油画或画布中的高音质音响系统，包括：具有弹性的底膜，设置在所述底膜周侧的主体框，与所述底膜、所述主体框围成一密闭的限定空间的盖板，设置在所述限定空间内、且设置在所述底膜上、用于使所述底膜的内表面和外表面振动的音频激励器结构，及机械固定在所述主体框或加强条上、设置在所述限定空间内与所述音频激励器结构同相连接、且具有气动泵功能的密封箱结构。
优选地，所述音频激励器结构包括：设置在所述底膜上的固定板，设置在所述固定板上、至少一个的音频激励器；所述密封箱结构安装在所述固定板上方时、与所述固定板之间有5mm–10mm的空间。

图2是本实用新型的另一结构示意图。
图3是本实用新型的结构分解示意图。

 具体实施方式
下面结合附图，具体阐明本实用新型的实施方式，附图仅供参考和说明使用，不构成对本实用新型专利保护范围的限制。
实施例1：
请参考图1-图4，本实用新型的一种内嵌于油画或画布中的高音质音响系统，底膜1、主体框2、盖板3、音频激励器结构4、密封箱结构5，其中，所述主体框2设置在所述底膜1周侧，所述音频激励器结构4设置在所述底膜1上、用于使所述底膜1的内表面和外表面振动，所述密封箱结构5机械固定在所述主体框2或加强条6上、设置在所述限定空间内与所述音频激励器结构4同相连接、且具有气动泵功能，所述限定空间为密闭空间。
具体地，所述底膜1为具有弹性的结构，所述底膜1为布或薄膜。所述底膜1可以为布或薄膜，所述底膜1也可以由合成材料制成，如尼龙，处理过的纸或天然织物，其厚度取决于使用的材料和绘画技术。进一步地，所述底膜1 的内表面及外表面均为无开口的连续表面。由于所述底膜1具有气密性且同时为弹性材料，将所述底膜1设置到所述主体框2上时，所述底膜1的内外表面均具有弹力，并且在力的作用下能够沿着X轴产生位移并返回原位。所述底膜 1在所述限定空间内会根据压力的变化产生声压或凹陷。
所述主体框2可以由木材、金属或者塑料制成。
所述盖板3包括：所述盖板包括：盖板本体31，设置在所述盖板本体31周侧的轮廓32，及设置在所述轮廓上的固定挂钩(图未示)。
所述音频激励器结构4包括：设置在所述底膜1上的固定板41，设置在所述固定板41上、至少一个的音频激励器42，所述音频激励器结构4设置在所述底膜1内表面的中心处，所述固定板41的表面包括所述底膜1面积十分之一至二分之一之间的表面，且所述固定板41的表面与所述底膜1的表面具有相同的几何比例，该结构的设置避免了零件在操作过程中相互接触，进而产生变形或不必要的振动的现象。所述固定板41设在所述底膜1和所述音频激励器42之间，其将所述音频激励器42的机电振动均匀地传递给底膜1内表面的中央部分，同时在底膜1与音频激励器42之间提供机械稳定性，所述音频激励器42将电音频信号转换为机械振动，由于所述音频激励器结构4的位置设置，使得所述固定板41能带动所述底膜1沿X轴向前或向后运动或快速的偏移。进一步地，所述音频激励器42可以为磁动力换能器，所述固定板41的表面厚度可以根据所要获得的频率响应或所述底膜1的厚度而变化，其材料是能够随时间推移提供较高的刚度，重量轻和可靠的机械特性的蜂窝材料。更进一步地，所述固定板41可以使用其他刚性轻质的材料如木材、纸板、铝。所述固定板41通过粘合剂限制在所述底膜1的内表面的一部分表面上，所述音频激励器42的动圈和所述固定板41也通过粘合剂粘合固定。
所述密封箱结构5通过加强条6设置在所述主体框2上，所述密封箱结构5 通过螺钉固设在所述加强条6上，所述密封箱结构5包括：外框51，设置在所述外框51内、与所述外框51之间有隔离空间的扬声器52，所述密封箱结构5 与所述底膜1的内表面之间有5mm-10mm的空间，当所述密封箱结构5设置在所述固定板41上方时，与所述固定板41之间有5mm-10mm的空间。进一步地，所述扬声器52用作气动泵，所述扬声器52与所述音频激励器42同相连接，工作时，具有气动泵功能的所述扬声器52将从该隔离空间中抽出，以减少所述限定空间的压力P6 ，限定空间的压力P6和隔离空间的压力P61随电正弦波的变化如图4所示(fig .4)，在体积起点处，P6和P61的压力相等，在正半波(1) 期间，限定空间的压力P6将大于隔离空间的压力P61，这意味着具有气动泵功能的所述扬声器52从限定空间吸收压力进入限定空间，结果将是所述底膜的内表面和外表面向外移位，在负半波期间，限定空间音量的压力P6将低于隔离空间音量压力P61，因此具有气动泵功能的扬声器52会在限定空间中产生压力，而在隔离空间中产生压力，进而导致所述底膜内表面和外表面向内移位。更进一步地，所述限定空间和隔离空间的压力差导致在底膜1的内表面上均匀分布的力，使其与音频激励器42的位移同相，然后沿着底膜内表面的X轴的位移和外表面的位移将更大，因此将有可能再现声谱的低频，而音频激励器42也以相同的方式跟随底膜1的内表面产生位移，因为它被约束在内表面上，并且同时它能够以不需要高位移的中高频和中高频振动所述底膜1的内表面外表面，从而达到推或缩相同内表面外表面的不同波长的重叠导致系统在整个音频频带上的极好的声音再现，进而达到了具有音质效果好、组件成本较低、制造复杂程度降低及稳定性较好等目的。需要说明的是，所述密封箱结构5可直接设置在所述主体框2上。所述隔离空间为圆柱体型，所述外框51也可根据需要设计为其他几何形状。
以上所揭露的仅为本实用新型的较佳实施例，不能以此来限定本实用新型的权利保护范围，因此依本实用新型申请专利范围所作的等同变化，仍属本实用新型所涵盖的范围。
