摘要： A repulsion magnetic circuit type loudspeaker which is compact and easy to assemble, and a method of easily manufacturing such a repulsion magnetic circuit type loudspeaker by using conventional loudspeaker manufacturing lines. The repulsion magnetic circuit has two magnets magnetized in the thickness direction and disposed with the same polarity being faced each other, and a center plate being squeezed between the two magnets. A magnetic field is generated by repulsive fluxes at the outer peripheral area of the center plate. A voice coil is disposed in the magnetic field. In the manufacturing method, a coupling member of either a concave or a convex is formed at each of the contact planes of the magnets and center plate. The coupling members are engaged with each other to assemble the repulsion magnetic circuit. The repulsion magnetic circuit is mounted on a speaker frame with position alignment therebetween, by forming a convex or concave at the speaker frame, the convex or concave matching a concave or convex formed at the lower magnet.

摘要： A volume ratio of conductive material to a voice coil is improved by using a tape coil wire, and a magnetic efficiency of the voice coil is improved by attaching magnetic material to conductive material of the coil wire. A tape coil wire having a predetermined width is wound about a voice coil bobbin to form a voice coil. The winding start portion of the voice coil is soldered to the exposed area of the voice coil bobbin. A projection of the voice coil bobbin forms the winding start terminal. A folded portion of the winding end portion of the voice coil forms the winding end terminal. Input signal lead wires on the damper are electrically connected to the winding start and end terminals to drive the cone paper by the voice coil.

摘要： Additional information for each musical program is automatically recorded on an optical disc. A digital voice signal reproduced from a mini-disc is sent to an MD system via a digital voice signal line and recorded on another mini-disc. Additional information such as the title of a musical program is sent via a serial communication line 6 to a MD control microcomputer and stored in its RAM which stores U-TOC information. The U-TOC information stored in RAM is recorded on the mini-disc before it is dismounted from the MD system.

摘要： An FM tuner capable of speeding up an AF search and a PTY search. A tuning operation by the FM tuner with an RDS demodulator is continuously controlled until an optimum tuning condition is reached in accordance with a tuned signal output from a detector or with a count of an intermediate frequency. The FM tuner has an AF search performing key for performing an AF search, a PTY performing key for performing a PTY search, and a changeover unit for switching to the tuned signal for decisioning whether an optimum tuning condition is reached when the AF or PTY search is performed.

摘要： Large characters and numerals of a lapse time, a musical program title, or the like of a musical program under the performance recorded on a photomagnetic disc can be displayed, and an inadvertent erase of a musical program can be prevented. The TNO and lapse time of each musical program during the performance are displayed on a display unit as shown in Fig.3 at (f). Under this condition, when a title key is depressed, the title for the TNO is displayed for a predetermined time period on the display unit as shown in Fig.3 at (g). After the predetermined time period, the lapse time for the TNO is displayed as shown in Fig.3 at (h). When an erase key is depressed during the performance of a musical program, a controller erases the disc management information and additional information for the TNO from a RAM storing U-TOC information, and renumbers other TNOs to update the contents of RAM. Upon depression of a tray open key of a key matrix, the controller instructs an MD record/reproduction unit to stop the reproduction and copies the management information and additional information for the TNO stored in RAM to another RAM and records the copied information to a U-TOC area of a mini disc. Thereafter, the MD record/reproduction unit operates to eject out the disc cartridge.
