本発明は振動板の前面に開口率が自由に変えられるイコ
ライザーを配置したスピーカに係り、聴取しながら音圧
周波数特性を可変できるようにしようとするものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker in which an equalizer with an aperture ratio that can be freely changed is arranged in front of a diaphragm, and is intended to enable the sound pressure frequency characteristics to be varied while listening.
一般に中高音用スピーカにおいては、振動板の前面にイ
コライザーを配置して振動板の保護と、高音域における
音圧周波数特性の盛上げを計つていた。Generally, in speakers for medium and high frequencies, an equalizer is placed in front of the diaphragm to protect the diaphragm and to enhance sound pressure frequency characteristics in the treble range.
しかしながら、従来においては、このイコライザーは一
定の形状をしており、イコライザーを用いることによつ
てスピーカとしての開口率が一定となり、一定の音圧周
波数特性を得ることしかできないものとなつていた。However, in the past, this equalizer had a fixed shape, and by using the equalizer, the aperture ratio as a speaker was fixed, and it was only possible to obtain a fixed sound pressure frequency characteristic.
本発明は以上のような従来の欠点を除去するものである
。The present invention eliminates the drawbacks of the prior art as described above.
以下、本発明の実施例を図面第１図〜第４図により説明

An edge portion of a flat diaphragm 7 is fixed to the upper surface of the magnetic circuit 1 via a fixing ring 6, and a voice coil 9 that fits into the magnetic gap 8 of the magnetic circuit 1 is attached to the lower surface of the flat diaphragm 7.

An equalizer main body 15 having a disk shape and three fan-shaped openings 14 provided in the disk portion 13 is disposed.
An adjustment plate 17 having three equal intervals of 6 is rotatably attached by a rivet 18.

It is fixed to the baffle plate 10 by. With this configuration, the aperture ratio can be increased by rotating the adjustment plate 17 so that the aperture 16 of the adjustment plate 17 completely matches the aperture 14 of the equalizer body 15. can be set to 0, and the aperture ratio can be changed from the total area of the three openings 14 to 0.

に構成することもできる。By adjusting the aperture ratio, the rise of the sound pressure frequency characteristic in the high frequency range can be arbitrarily adjusted, and the sound pressure frequency characteristic can be controlled in accordance with the program played by the listener. As shown in FIG. 4, another example of an equalizer includes three radial mounting legs 12, an equalizer body 15 with a circular opening 14 in the center, and a disk-shaped body 15 that closes the opening 14. It is also possible to configure the adjustment plate 17 to be detachable by magnetic force so that the aperture ratio can be adjusted in two ways.

的価値の大なるものである。Since the speaker of the present invention is configured as described above, it has the effect of preventing damage to the diaphragm due to the intrusion of external objects, and the effect of increasing the sound pressure frequency characteristic in the high frequency range by adjusting the aperture ratio. Since it can be adjusted arbitrarily, it is possible to listen with characteristics suitable for the playback program, which is of great practical value.
