THE USER DETECTIVE SOUND SYSTEM

摘要

PURPOSE: A sound system detecting a user position is provided to improve sound environment by rotating a satellite speaker with a wanted angle using a remote controller. CONSTITUTION: An ultrasonic sensor(00) senses the position change of a user(11) for rotating a speaker. The designated 9 spots are set in an AVR. A remote controller selects and rotates a satellite speaker with a wanted angle. If the designated number is pushed by an IR sensor and the remote controller, the satellite speaker automatically rotates toward the wanted spot. A servo motor is connected to a servo motor control module and rotates the satellite speaker.
