装置を提供しようとする。ものである。The present invention eliminates the above-mentioned conventional drawbacks, and by improving the cabinet, it prevents the occurrence of peaks and dips in the vicinity of the crossover in the sound pressure frequency response, and achieves a flat sound pressure frequency characteristic. The present invention aims to provide a speaker device that can be used as a speaker device. It is something.

る。That is, (1) the present invention makes the ceiling surface of the cabinet a part of the 70-channel road horn, and provides a stepped portion projecting upward on the rear side of the ceiling surface, (1) attaches a bass speaker to this stepped portion, and then attaches the bass speaker to the ceiling. It is characterized in that it is placed close to the acoustic sensor placed on the surface to flatten the characteristics near the crossover in the sound pressure frequency characteristics.
以下、本発明の一実施例を図面第３図、第４図により説
明する。An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.
８は木材１合成樹脂あるいは金属よりなるキャビネット

る。A horn tweeter 14 is mounted horizontally on the upper part of the ceiling surface of the cabinet 8 using the stepped portion 11. - With this configuration, it is possible to use a loudspeaker for lower frequencies than K, and since both are assembled with the stepped portion 11 as a reference, the positioning of the vibration system of each speaker in the depth direction is accurate, and the sound pressure frequency characteristics are also improved. Flat playback is also possible with crossover, and the sound source between low and high frequencies is also radiated from the same part, which prevents low and high frequencies from being played disjointedly as in the past, allowing for more faithful playback. becomes.

利点をもち、工業的価値の大なるものである。As described above, in the speaker device of the present invention, the bass speaker and the horn lighter are arranged close to each other, and their mounting position is also determined by the stepped part of the cabinet, so the trough position is also constant, and the sound pressure frequency Characteristics near the crossover can also be made extremely stable and flat, making high-fidelity reproduction possible.This stepped section can also support the horn tweeter, so the number of components can be reduced. It has the following advantages and is of great industrial value.
