壁画音箱是属于济南音响的一组成部分，并非就是指壁画音响，不可混淆。大家知道音箱为音响的一个组成部分，然而音响是由包括功放、周遍设备（包括压限器、效果器、均衡器、VCD、DVD等）、扬声器（音箱、喇叭）调音台、麦克风、显示设备等等加起来一套完整系统

Murals speaker is a part of belonging to the Ji'nan sound, not means the mural sound, not be confused. We know that the speaker is a part of the sound, but is composed of power amplifier, audio accessories (including limiter, effects, equalizer, VCD, DVD etc.), the speaker (speaker, speaker, microphone, mixer) display equipment and so on add up to a complete set of system

壁画音箱结构特点1、驱动器。它相当于平板音箱的一个心脏。济南音响驱动器的设计要点是它的有效冲程非常的小，一般不超过2m/m2；其次是音圈部分不能太重，否则高频部分会有较为严重的失真。设计要求重量要轻，体积要小，磁力需大。基于以上因素，我们采用高磁的材料，一般磁束密度要大于10000高斯以上，才能有较好的表现力。有时为了提高输出，使用两个驱动体或四个驱动体来提升输出音压，而且使用多个驱动体，能够获得更佳的频响曲线，至于使用几个驱动体取决于振动板面积的大小和重量,托微克的采用高科技智能激发器,在保证产品高品质音质的情况下,保证了产品的使用安全。

The structure characteristics, drive 1 murals speaker. It amounts to a flat panel speaker of a heart. Design points of Ji'nan audio driver is effective stroke it very small, generally not more than 2m/m2; the second is the voice coil portion is not too heavy, otherwise the high frequency part can have serious distortion. Design requirements for light weight, small size, large magnetic force required. Based on the above factors, we use high magnetic materials, general magnetic beam density should be greater than 10000 Gauss above, can have good expressive force. Sometimes in order to improve the output, using the two driving body or four drive body to enhance the output sound pressure, and using a plurality of drive body, can obtain better frequency response curve, as the size and weight of the use of several driving body depends on the vibration plate area, supporting micrograms of using high-tech intelligent excitation device, in order to ensure product quality quality under the circumstances, to ensure safe use of the product.

2、振动板。它就像人的声带一样，对于音色、声音的大小、声音的平整度起到决定性作用，因此在平板式音箱中占有仅次于驱动体（Exciter）的重要作用。

2, the vibration plate. It is like the human vocal cord, the decisive role played for the smoothness of timbre, the size of the sound, the sound, therefore in the plate type sound box next to the driver plays the important role of the body (Exciter).

3、悬吊系统。平板式音箱的振动原理与一般传统喇叭的振动原理完全不同。一般的传统喇叭，它采用的活塞式的振动方式；而平板音箱的振动则采用随机振动的

3, the suspension system. The principle of vibration plate type sound box vibration theory and the general traditional horn is completely different. The general traditional horn, the mode of vibration of piston type it uses; and the vibration plate speaker using random vibration

方式，因此它的最低共振频率并非只有一个点，而有十几个点，设计良好的平板音箱，甚至有二十几个点。而且它的驱动点并不是在正中央，因为正中央并不能获得

The lowest resonance frequency mode, so it's not only a little, and there are about a dozen, flat panel speaker design good, and even have more than 20 points. And it's driving point is not right in the middle, because the central and can't get

最大声压和最平滑的频响曲线，而是在节振动的最佳位置，另外再加上1:9比例的四个悬吊点，组成合理的悬吊系统。

The maximum pressure and the smooth frequency response curve, but in the best position to vibration, four point suspension plus the ratio of 1:9, the composition of the suspension system and reasonable.

4、背板。济南音响后壳的设计必须考虑到在后壳上开口来增加声波的绕射问题，因为平板音箱是波浪型振动。同样的它的背面会产生相同的声压（只是相位不同），所以必须有窗口来增加声辐射，这样一来也就具有更好的指向性，不受因为聆听者位置的不同而产生不同的声音效果,托微克在产品设计时充分考虑到这点,更使音质在行业中处于领先地位。

4, backplane. The design of Ji'nan sound after the shell must be taken into account in the back shell opening to increase the diffraction problem of sound waves, because flat speaker wavy vibration. The same the back of it will produce the same sound pressure level (just a different phase), so there must be a window to increase radiation, so it has better directivity, not because of the different position by the listener produces different sound effects, tovic in product design fully consider this point, so the tone is more a leading position in the industry.
