摘要： PROBLEM TO BE SOLVED: To provide a loudspeaker, capable of efficiently feeding reverse electromotive components generated between the start terminal and the end terminal of a voice coil to a feedback control section of a main amplifier section, without causing adverse effects due to the presence of a lead connection section. SOLUTION: A magnetic gap 18 is formed at the bottom of a frame 14a of the loudspeaker 14, and a bobbin 20 around which a voice coil 19 is wound is arranged in the inside thereof. A leading section, continuing to the start terminal of the voice coil 19, is provided extended along the surface of a bobbin 20 and provided extended along the surface of a diaphragm 22, and is commonly connected to one ends of respective tinsel wires 24 and 26. The other ends of the tinsel wires 24 and 26 are respectively used as an input terminal 24a and a detection terminal 26a. Also, tinsel wires 25 and 27 of the same type are provided on a leading section which continues to the end terminal of the voice coil 19. The terminal 24a is connected to a hot signal terminal 7 of a main amplifier section 1 by using a signal line L1, and the terminal 26a of the wire 26 is connected to a first remote detection terminal 9 by using a remote detecting line L3.

摘要： PROBLEM TO BE SOLVED: To reproduce rich sound giving an excellent ambience by intensifying acoustic expression according to listener's liking. SOLUTION: A receiving part 1 receives on-the-spot broadcasting of sports such as baseball. An additive input selector 8 selects a desired sound source from a CD device 5, an MD device 6, and another sound source device 7, according to listener's liking, to supply it as an additive input to a mixer 2. In the event that an additive input is given from the additive input selector 8, the mixer 2 adjusts the level of the additive input as desired by a listener's external operation and superimposes it on reproduced/received information from the receiving part 1 and supplies the synthesized information to an amplifier 3. In the event that no additive sound source is selected by the additive input selector 8, the mixer 2 supplies only broadcast information from the receiving part 1 to the amplifier 3. The amplifier 3 suitably amplifies inputted information and supplies it to a speaker system 4 for sound reproduction.

摘要： PROBLEM TO BE SOLVED: To provide an audio system that can properly maintain listening of music by a user. SOLUTION: When acquiring data multiplexed in a broadcast radio wave corresponding to an RDS(radio data system) from a tuner 11, an arithmetic processing section 15 sequentially discriminates whether or not a current program broadcasts music according to a PTY(program type) value included in the data. When the arithmetic processing section 15 discriminates that no music is broadcast while selecting the tuner 11 for an input source, the arithmetic processing section 15 controls changeover switch 14 to select a music reproduction device 12 for the input source and allows the music reproduction device 12 to reproduce prescribed music. Whereas, while selecting the music reproduction device 12 as the input source, when the arithmetic processing section 15 discriminates that music is broadcast, the arithmetic processing section 15 controls the changeover switch 14 to select the tuner 11 for the input source.
