Embodiment Construction

[0021] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0022] Such as figure 1 and figure 2 As shown, a printed circuit board 2 for processing signals is provided inside an audio device such as a radio. Moreover, a variable capacitor 4 is arranged on the upper part of the above-mentioned printed circuit board 2 , and a driven gear 6 is arranged on the above-mentioned variable capacitor 4 . Because the above-mentioned driven gear 6 is arranged on the rotating shaft of the variable capacitor 4, when the above-mentioned driven gear 6 is actually rotated, the electrostatic capacity of the above-mentioned variable capacitor 4 can also be changed.

[0023] Moreover, the drive gear 16 meshed with the driven gear 6 is connected to the top of the tuning chassis 18 and is rotatable. And the above-mentioned driving gear 16 is rotated by the button shaft 12 and the tuning button 10 . The above-mentioned tuni...

Abstract

A turner unit for acoustics contains turning button with button axle extended toward internal direction of acoustics, variable capacitor, driven gear, driving gear. Said invention can adjust electrostatic capacity of variable capacitor by universal interface without auxiliary printed circuit board and other device even the rotary axle of turning button is not axial with rotary axle of variable capacitor.

Description

(1) Technical field [0001] The present invention relates to audio devices such as radios, in particular to a tuning device for an audio device in which an adjustment button that is not coaxial with a variable capacitor can be used to operate the tuning device in the influencing device of the variable capacitor. (2) Background technology [0002] Generally speaking, in audio equipment such as radios, there are variable capacitors that can variably adjust the electrostatic capacity. Moreover, adjustment buttons such as volume adjustment buttons are provided on the outer side of the radio or the like. By rotating the button, the rotating shaft of the above-mentioned variable capacitor is operated, so that the purpose of adjusting the electrostatic capacity can be achieved. [0003] Moreover, in order to enable the rotary shaft of the button to operate the shaft of the rotary variable capacitor, the two shafts are substantially set to be coaxial. However, in order to be able t...
