Abstract:
Disclosed are a tweeter, a vibration structure and an inverted concave diaphragm thereof, and a manufacturing method and a sound effect reproduction method therefor. The tweeter comprises a magnetic loop unit, a voice coil, a baffle and a vibration unit. The vibration unit comprises an inverted concave diaphragm and an elastic flange. The elastic flange comprises a flange body, and an inside connection edge and an outside connection edge integrally extending from the flange body. When the inside connection edge of the elastic flange is integrally combined with at least part of a surface of the inverted concave diaphragm, the outside connection edge of the elastic flange is integrally combined with at least part of a surface of the baffle. One end of the voice coil is arranged on the inverted concave diaphragm, and the other end of the voice coil is coupled to the magnetic loop unit. The tweeter can produce high-pitched voice with a high frequency of 2560 Hz or more and can even produce high-pitched voice with an ultra-high frequency of 40 kHZ or more so as to improve the high pitch reproduction of the tweeter.
