    Abstract: A transmitter (1) converts an input signal from a microphone (2) into a plural-bit digital signal by means of an A/D converter (4) at predetermined time intervals. An encoder (6) divides the digital signal into plural blocks and adds a parity bit to each block to thereby form a coded signal. A transmitting unit (8) modulates a carrier with the coded signal and transmits the modulated carrier through an antenna (10). A receiver (12) includes two tuning units (18A, 18B). Corresponding coded signals outputted from the tuning units (18A, 18B) are inputted to a decoder (20). The decoder (20) makes a parity check on respective blocks of the corresponding coded signals and selects and outputs an error-free one of the corresponding blocks of the corresponding coded signals.

    Abstract: A speaker system with a woofer and tweeters as a whole disposed in a subs tantially coaxial relationship is provided to make an acoustic wave radiated from the woofer less interfere with an acoustic wave radiated from the twee ter in at least one direction and to make an acoustic pressure-frequency cha racteristic easily stable. A speaker system (1) is comprised of a woofer (2) and not less than three tweeters (3), wherein the tweeters (3) are disposed in an arc-like form in front of the woofer (2).
