Abstract
1,246,551. Diaphragm vibrators. P. SPADINI. 17 June, 1969 [17 June, 1968 (2)], No. 30641/69. Heading G5J. [Also in Division G3] An alarm buzzer in a wrist watch (see Division G3) comprises a spring blade 111 electromagnetically vibrated so that a projection 113 thereon strikes a conical sound producing membrane 114. The blade 111 is secured at its ends to a frame 109 and has fixed thereto an armature 112 disposed adjacent a ferromagnetic core 98 secured to a ferromagnetic plate 97 on which are two permanent magnets 99 (Fig. 4, not shown) having therebetween two coils 103, 104 surrounding the core 98. Oscillatory currents in the coils 103, 104 cause the spring blade 111 to vibrate and sound the alarm. The coils 103, 104 are arranged in a transistor oscillator circuit. The membrane 114 is carried by a ring 115 which is screwed into the watch case into a position wherein a desired sound is produced by the engagement of the projection 113 with the membrane 114. A perforated cover-plate 118 locks the ring 115 in its adjusted position.
