Abstract
PURPOSE: To improve tone quality and sound volume by fixing a speaker cone directly to one surface of a case having sealed structure when the voice information recorded on a record disc is taken-out as mechanical vibration and the vibration is transmitted to the speaker cone to convert the vibration to sound.
CONSTITUTION: When a needle arm 12 and a return arm 16 are at the initial position as shown in the figure, a record disc 1 is pushed up by a spring 9, and a needle 10 contacts with the start point of a groove. When revolution is applied to the disc 1 through a belt 4 by a motor 3, the needle transfers relatively towards end point from the start point of the groove. During this time, the voice information recorded on the groove is taken out as mechanical vibration by the needle 10, and this vibration is transmitted from the needle arm 12 to the speaker cone 11 and converted directly to sound voice. At this time, the peripheral part of the speaker cone 11 is fixed onto one surfce of the case 30 in sealed structure, and thus stable support of the speaker cone 11 is enabled, and sufficient tone quality and sound volume can be obtained.
