Problems solved by technology

Compared with the phonograph without volume control function invented by Edison, this function is a great improvement, but at the same time, it also causes an inevitable problem, that is, in real life, the volume range of the original sound is relatively fixed, such as The sound of insects, people talking, live concerts, etc., when the electronic product records or simulates the original sound, the volume of the sound cannot be adjusted; when playing these sounds, because the player itself has a volume adjustment function, the It will change the actual volume of the sound, which has a certain gap with the original volume. Although the sound itself is not distorted, it is not easy to achieve the effect of the original sound

Abstract

The present invention relates to one sound controller and aims at providing one sound controller with sound volume either regulated according to practical requirement or restored to its original volume in the environment the sound is record. The present invention includes successively connected simulating/synthesizing/replaying circuit, output circuit, sound amplifier circuit and loudspeaker as well as one characterized output selecting switch for switching between the adjustable volume and original volume. The present invention has such volume as simulating the sound volume of true object or the volume in the true environment and gives out true sensing.

Description

technical field [0001] The invention relates to an electronic control device, in particular to a sound control device capable of outputting sound according to the original volume. Background technique [0002] At present, any electronic product that can emit sound has the function of adjusting the volume, that is, the volume can be weakened or increased according to the user's needs, so as to achieve the purpose of adapting to different occasions and different users. Compared with the phonograph without volume control function invented by Edison, this function is a great improvement, but at the same time, it also causes an inevitable problem, that is, in real life, the volume range of the original sound is relatively fixed, such as The sound of insects, people talking, live concerts, etc., when the electronic product records or simulates the original sound, the volume of the sound cannot be adjusted; when playing these sounds, because the player itself has a volume adjustmen...
