Filed: 2008-03-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of preventing a Karaoke apparatus from malfunctioning by recognizing that a user carrying a mobile terminal exits from a room.  <P>SOLUTION: When a Karaoke use program is actuated by user's input operation, the mobile terminal transmits a connection request signal including mobile terminal ID information on itself to a nearby Karaoke apparatus by an infrared communication means, and the Karaoke apparatus sends back a connection acknowledgement signal including its Karaoke apparatus ID information to the mobile terminal having sent the connection request signal in response to the signal, and always transmits an ID notice signal including Karaoke apparatus ID information repeatedly by an infrared communication means. The mobile terminal stores the Karaoke ID information in the connection acknowledgement signal in a memory. When the mobile terminal outputs an operation signal in predetermined format to the Karaoke apparatus through a short-distance radio communication means based upon an indication input from an operation input means, the mobile terminal contrasts the Karaoke apparatus ID information in the received ID notice signal that the Karaoke apparatus transmits with the Karaoke apparatus ID information stored in the memory to output the operation signal to the Karaoke apparatus corresponding to the Karaoke apparatus ID information when they match each other or to stop the output of the operation signal when not.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To solve the problems that one microphone is required for each function when a noise canceling function and a sound recording function coexist in one device, thereby requiring the totally two microphones, and also that reproduction music has to be turned off in sound recording since the reproduction sound is put as noise on the sound to be recorded when simultaneously performing reproducing/recording in an environment where the microphone for sound recording exists close to the speaker.  <P>SOLUTION: The microphone for noise canceling is commonly used also as the microphone for sound recording, thereby sharing one microphone which is normally required to be two. The reproduction sound is converted to have a reverse phase in sound recording, and added to an output from the microphone for sound recording, so that the reproduction sound to come from the speaker close to the microphone into the microphone for recording is canceled. Thus, even when the reproduction music is not turned off, the sound in the circumference is recorded without worrying about the noise from the speaker.  <P>COPYRIGHT: (C)2010,JPO&INPIT
