Abstract:
The present invention addresses the problem of providing a virtual sound image control system, a lighting apparatus, a kitchen device, a ceiling member, and a table which enable a plurality of users to three-dimensionally recognize a sound image by means of a simple configuration provided with two-channel speakers. In this virtual sound image control system 1, a signal processing device 2 generates an acoustic signal such that a user H three-dimensionally recognizes a virtual sound image, and outputs the acoustic signal to two-channel speakers 31, 32. The respective output directions of the two-channel speakers 31, 32 are the same direction, and the two-channel speakers 31, 32 are disposed aligned with one another in the output direction.
