The utility model relates to the technical field of loudspeaker shock film, in particular to a full frequency band plus ultra-high frequency loudspeaker shock film, which comprises a vibration plate body, a vibration plate fold ring, and a voice ring. The voice ring is located at the bottom of the vibration plate body, and has a dust-proof cap which is connected to cover the voice ring. The vibration plate fold ring is located at the upper part of the vibration plate body, and the two cooperate with each other, and are in the vibration plate fold ring Add a corner at the joint of the edge and the vibrating plate body. The utility model uses the reflection principle of sound wave, adding an angle at the joint of the inner edge of the vibration plate fold ring and the vibration plate body can greatly strengthen the strength of the cone of the paper basin, so that the cone of the paper basin can vibrate upward and downward at the same time when the ultra-high frequency is above 20kHz to 40Hz; when the speaker pushes the air, the angle of the vibration plate body is reflected twice, so that the frequency response curve of the speaker reaches ultra-high frequency 4 0KHz. More than three loudspeakers are replaced by one loudspeaker, which has the effect of high, middle and low tones; the frequency bands are connected smoothly without overlapping interference.

一种全频段加超高频扬声器震膜
本技术涉及扬声器震膜
,具体为一种全频段加超高频扬声器震膜。
技术介绍
欲使现有音箱达到高、中、低音的全频效果,至少须配两个以上扬声器,要求更高的音箱更同时配备专业的高音、中音、低音、超高音扬声器,且超高音扬声器频率响应曲线一般只能达到20KHz。而采用两个以上扬声器存在高、中、低音频重叠或衔接问题,若达到两个不同音域的无缝对接或完全不重叠几乎不可能实现,就会产生重音干扰或者衔接不理想现象,业界也有采用加装一个或数个分频器来解决该问题,即利用分频段切割除去不需要的部分音频,但分频器本身造价昂贵,还涉及到电子、电路设计,成本很高且繁琐。
技术实现思路
本技术的目的在于提供一种全频段加超高频扬声器震膜,以解决上述
技术介绍
中提出的问题。该全频段加超高频扬声器震膜,以一个扬声器取代三个以上扬声器,同时具备高音、中音、低音效果,且频响曲线可以达到40KHz的超高频效果;各频段衔接顺畅,无重叠干扰现象。为实现上述目的,本技术提供如下技术方案:一种全频段加超高频扬声器震膜,包括振动板本体、振动板折环、以及音圈,所述音圈位于振动板本体的底部,所述振动板折环位于振动板本体上部,二者相互配合,在所述振动板折环内缘与振动板本体结合处加一折角。进一步的,具有相扣的防尘帽覆盖在音圈上。进一步的,所述具有相扣的防尘帽的边缘具有向内的弯折角。与现有技术相比,本技术的有益效果是:本方案利用声波的反射原理,在振动板折环内缘与振动板本体结合处加一 ...
