Problems solved by technology

Therefore, when a listener wants to hear the sound of a musical piece in the background while playing a musical instrument, for example, there are cases where although the listener wants to hear the sound of the musical instrument more clearly than the sound of the musical piece, it is also possible to clearly The sound of the music section can be heard accurately, so the sound of the music section may interfere with the hearing of the instrument sound

Embodiment Construction

[0032] [Appearance of speaker device 1]

[0033] figure 1 is a view illustrating the appearance of the speaker device 1 according to the embodiment of the present disclosure. The speaker device 1 is a musical instrument amplifier, and includes: a speaker section 2 configured by an L (left) channel speaker unit 2L and an R (right) channel speaker unit 2R, a monaural input terminal 3 , a stereo input terminal 4 , and an operation section 5. These elements are arranged in a housing 9 having a substantially rectangular parallelepiped shape. Among elements described below, elements indicated by reference signs appended with “L” correspond to the L (left) channel, and elements indicated by reference signs appended with “R” correspond to the R (right) channel. Elements denoted by reference signs appended with "M" correspond to monaural.

[0034] The speaker units 2L, 2R are arranged so as to emit sound in the normal direction of one surface of the casing 9 (hereinafter, this norm...

Abstract

A speaker device includes: a speaker unit; a first input part that provides an audio signal of one channel; a second input part that provides at least left and right channel audio signals; and a sound effect applying part that an audio signal supplied to the first input section performs first signal processing to output left channel and right channel audio signals; and an output section outputs the audio signal supplied to the first input section to at least one of the speaker units ; and a broadening effect applying section that performs second signal processing for applying a sound image broadening effect on both the left channel and right channel audio signals and the at least left channel and right channel audio signals, and processes the The audio signals are respectively provided to the speaker units for the corresponding channels.

Description

technical field [0001] The present invention relates to a technique for controlling sound image localization. Background technique [0002] In a sound emitting device that can emit sound in stereo, in the case where the interval between two speaker units is narrow, the apparent angle (apparent angle) of the position of the speaker unit when viewed from the listener is small, and it is largely felt Impression that widens sound field does not come. This is caused by the fact that the range in which a sound field can be localized is limited between the two speaker units in the case of using the two speaker units. Therefore, a technique has been developed in which the range in which a sound image can be localized is widened to the outside of the space between speakers by applying signal processing to audio signals to be supplied to the respective speakers. As such a technique for widening the range of sound image localization, various techniques have been disclosed, such as a ...
