Description

  The present invention relates to a technique for controlling sound output from a speaker device in an AV system including a television device and a speaker device so as to achieve appropriate sound elevation according to the size of the television device.

Today, with the development of technology, a theater rack in which speakers are attached to an AV rack that stores AV equipment has recently been released. However, since the TV that outputs video is in front of the user himself / herself in the theater rack, audio is output from the speakers provided in the AV rack below the TV. There has been a problem that a sense of unity is lost due to the occurrence of misalignment. In order to solve the problem, a function called sound elevation described in Patent Document 1 has been developed. Specifically, by correcting the specific frequency band included in the sound output from the speaker, the user who is the listener is output from a position higher than the height at which the sound is originally output. This is a technology that lifts the sound (makes the listener feel as if the sound has been lifted). This makes it possible to match the position of the audio to the height of the video.
