Embodiment 1

[0080] Adopt guitar amplifier 2 of the present invention, input the test signal of-10dBu on input terminal 31, pick up the center output signal output from center speaker 6 and the side output signal output from each speaker 7,8 by microphone, make it through Mixer, measured with a measuring instrument (AudioPrecision). In the state where the rear panel 12 is provided (in the case of implementing the present invention, the state where the rear side of each speaker 6 to 8 is covered) and the state where the rear panel 12 is not installed (the state where the rear side of each speaker 6 to 8 is opened) The experiment was carried out. In addition, the volume of each speaker 6-8 is an intermediate volume (an intermediate volume between the minimum volume and the maximum volume).

[0081] FIG. 7 shows the measurement data graph of the center output signal, and FIG. 8 shows the results of the experiment as a measurement data graph of the side output signal. In Fig. 7 and Fig. 8, t...

Abstract

The invention relates to a voice output amplifier which outputs voice from a plurality of loudspeakers without worsening tonal quality in the occasion of arranging a plurality of loudspeakers. A guitar amplifier (2) is provided with a loudspeaker cabinet (3), a CD player, a player box (5), a center loudspeaker (6), a left loudspeaker (7) and a right loudspeaker (8). The center loudspeaker (6) outputs voice signals inputted from outside. The left loudspeaker (7) and the right loudspeaker (8) output music signals regenerated by the CD player (4). The loudspeaker cabinet (3) is provided with a front panel (11), a rear panel (12), a left side panel (13), a right side panel, a top panel (15), a bottom panel (16), and intakes each loudspeaker (6 to 8) in the same space. The rear side of each loudspeaker (6 to 8) is shielded by the rear panel (12). A low diapason adjusting hole (11d) is formed on the front panel (11). An interface (19) connected with the low diapason adjusting hole (11d) is arranged on the front panel (11).

Description

technical field [0001] The present invention relates to amplifying an externally input sound signal and outputting the sound output amplifier from a speaker. Background technique [0002] A guitar amplifier, which is a sound output amplifier, amplifies a sound signal obtained by playing a guitar and outputs it from a speaker, and includes an amplifying device for amplifying the sound signal and a speaker for outputting the sound signal amplified by the amplifying device. When a guitar and a guitar amplifier are connected with a connecting cable, the sound signal obtained by playing the guitar is amplified and output from the speaker. [0003] Players who play guitar often practice while reproducing practice music. In this case, a music reproduction device (such as a CD player) for reproducing the practice music is prepared. However, it is troublesome to prepare a CD player in addition to the guitar amplifier. In order to solve this problem, a guitar amplifier equipped with ...
