Abstract

The invention relates to a sound effect processing circuit. The sound effect processing circuit comprises a sound source amplifying unit and is characterized by further comprising an echo effect processing unit, the echo effect processing unit comprises an echo amplifying circuit, a loudness degree adjusting circuit, an echo reverberation effect circuit and a sound effect selecting circuit which are all sequentially connected. Segmented adjustment is adopted for the sound effect processing circuit, sound needing to be adjusted is divided, and therefore the processed sound can be finer and smoother, the distinguishing degree is higher, the sound is more clear and pleasant to ears, the sound effect adjusted through the sound effect processing circuit can have a multi-auditory-sense effect, and the sound effect can be changed according to requirements. Lamplight warning is provided for overcurrent, and the situation that when sound source signals suddenly change, harsh sound is generated is improved.

Description

Technical field: [0001] The invention relates to the audio control field, and relates to an audio effect processing circuit. Background technique: [0002] With the continuous improvement of the quality of life, entertainment has become an indispensable part of daily life. Everyone has the need to sing and the urge to howl. Karaoke is an entertainment activity suitable for all ages. Karaoke karaoke halls have spread all over the streets and alleys of the city. However, singing in karaoke halls is not only expensive, but also limited by the venue, you cannot sing as you want. With the rapid development of the Internet, more and more users can realize online karaoke more conveniently, especially the application based on the terminal equipment has greatly improved the user experience. Many multimedia mobile terminals on the market support karaoke functions, but their products are difficult to meet user requirements. Existing karaoke multimedia mobile terminals can only simply...
