Abstract

The invention relates to a portable playing loudspeaker box. The loudspeaker box comprises a handle, a loudspeaker box main body, a button and a base cover. The loudspeaker box main body is formed by a cuboid enclosed box body. The foldable handle is arranged on the top of the loudspeaker box main body. A reverberation system formed by a two high pitch horns and a full frequency horn is arranged on one end face of an inner cavity of the loudspeaker box main body, and is fixed on a horn fixing plate in the loudspeaker box main body. The base cover equipped with a fixed column is fixedly installed at the bottom of the cuboid enclosed box body. A cell accommodation cavity equipped with a cell cover is arranged on the base face of the base cover. A loudspeaker circuit board is arranged in the cuboid enclosed box body. The beneficial effects are that realization of a small 2.1ch karaoke system is facilitated; a 6000MAH cell is arranged in the cuboid enclosed box body; the loudspeaker box is portable, and easy to move and use; realization of a dual wireless U-section microphone reverberation effect is facilitated; a Bluetooth receiving system is easily matched with a mobile phone; and a DSP software operation formula is provided.

Description

technical field [0001] The invention relates to a sound box device, in particular to a portable playback sound box for realizing a miniaturized 2.1ch karaoke system, a DSP software calculation program, a miniaturized 2.1ch karaoke system, and a wireless U-segment dual-microphone reverberation effect. Background technique [0002] The main purpose of the speaker is to prevent the sound wave signals on the front and back of the speaker diaphragm from directly forming a loop, so that only the high and medium frequency sounds with a small wavelength are transmitted. Speakers are one of the most important components in audio equipment. There are many types of classification, according to the way of energy conversion, it can be divided into electric type, electromagnetic type, piezoelectric type, digital type, etc.; according to the structure of the diaphragm, it can be divided into single paper cone, composite paper cone, composite horn, coaxial, etc. According to the beginning ...
