Bass loudspeaker apparatus and multiway loudspeaker system having the same

Abstract

A bass loudspeaker apparatus capable of according with a horn-type midbass in both the appearance and acoustics is disclosed. A bass loudspeaker apparatus A is provided with a cabinet 70 having an inner space 75 and a sound emission opening 71 in a front section; a corn-type woofer 3 disposed within the cabinet 70; a baffle plate 2 having a woofer mounting section 72 and vertically disposed in the inner space 75 so as to face the sound emission opening 71; a resonant chamber 73 defined in front of the baffle plate 2 for communicating with the sound emission opening 71. The front ends of the loudspeaker apparatuses A and 80 are approximately aligned in the state that the sound source position of the bass loudspeaker apparatus A is aligned with that of the horn-type midbass 80. Thus, the uniformity in the appearance is secured. The resonant chamber 73 and the sound emission opening 71 are respectively designed such that resonance occurs between an air mass around the periphery of the sound emission opening 71 and an air spring within the resonant chamber 73 at a predetermined frequency range of 150 through 400 Hz. Therefore, the distortion in the frequency characteristic produced in the resonant chamber 73 can be easily corrected.

Description

technical field [0001] The present invention relates to a speaker device for woofers constituting a multi-channel speaker device, and a multi-channel speaker device including the speaker device for woofers. Background technique [0002] If the horn of the horn-type speaker device is made into a device capable of reproducing up to the bass, the horn must be bent halfway due to its large size, and the corner of the room, etc., may be used for practical use. The horn type has many enthusiastic fans because of its good transition characteristics and clear bass sounds. Although this horn-type speaker device can reproduce clear bass sounds, it cannot reproduce bass to treble sounds while maintaining the same distance from the sound source of the speaker device to the listener. Therefore, in general, horn-type speaker devices are often used up to mid-range, and direct-radiation type speaker devices are often used for bass. [0003] For a multi-channel speaker device, it is import...

AI Technical Summary

Problems solved by technology

[0007] The above multi-channel loudspeaker device cannot improve the phase shift caused by the difference in the position of the sound source, and the forced filtering of the splitting circuit will also cause the phase shift of the circuit

Such an effect may not be clearly manifested in the continuous wave measurement in the laboratory, but it will be fully manifested in the actual music reproduction process with complex waveforms changing from time to time

[0008] In this way, when constituting a multi-way speaker device that uses both the horn-type mid-range speaker device and the direct-emission type woofer speaker device, problems arise in the integrity of the appearance and the overall feeling of the sound.
