Abstract: A karaoke device with built-in microphone includes a main body microphone, and converts an audio signal from the microphone into audio data by an A/D converter, and writes the audio data into a ring buffer by mixing with the data already stored in the ring buffer. If an echo mode is set, a delay time constant (CD) corresponding to the echo mode is determined, and on the basis thereof, a size of the ring buffer is set. The data is read from the ring buffer, and is inputted in a sound channel. If a voice effect mode is set, a reproduction frequency constant (CF) corresponding to the voice effect mode is determined, and based thereon, an inclement value of a read pointer of the ring buffer is determined, and then, the data is read from an address indicated by the read pointer. When the read pointer reaches the delay time constant, the relevant constant is subtracted from the read pointer value.

Abstract: A console for a vehicle includes a sliding-type lid which is mounted on a console body having a tray and which opens and closes an opening in an upper surface of the tray. A goods-supporting member is mounted on the lid and is capable of being selectively moved between an operative position in which it protrudes toward the opening in the tray to prevent the falling-down of goods put in an upright attitude in the tray, and a standby position in which it is housed in the lid, when the lid is in its opened position. Thus, it is possible to prevent the falling-down of the goods put in the upright attitude in the tray without bringing about decrease in internal volume of the tray and increase in size of the console body.
