High frequency response of high-power horn speaker

2022 10/27

Because the diaphragm of high-power horn speakers is relatively large and heavy. Therefore, when designing loudspeakers, their high frequency response is particularly important. In addition to increasing the magnetic flux density and reducing the weight of the sound film, it is a common practice to add a phase modulator (hereinafter referred to as the phase modulator) to the front end of the sound film among various factors of the loudspeaker. Method for high-frequency compensation. Generally, there are two types of sound film shapes for loudspeaker. Conditions for the added phase modulator.

Among them, A-type speaker diaphragm phase modulator is easier to design. However, the shape of diaphragm is complex and easy to deform, which is not conducive to production, especially its application in high-power loudspeakers. Type B diaphragm is not easy to deform. If the phase modulator is high, it can be compensated. However, when considering low frequency playback at the same time, it is necessary to retain the necessary rear cavity magnet and open holes. This is the volume of this horn speaker head.

The weight is too large, and dust and moisture can easily enter the magnetic gap. It is not suitable for some occasions with limited volume and weight, windy sand and heavy rain. In this way, adoption has become a problem that we must consider.
