Problems solved by technology

[0002] Existing broadcasting equipment in public places such as subways, airports, docks, etc., when the scene environment is noisy, the volume will be insufficient and affect the broadcasting effect. In order to improve, the playback volume can only be increased, but the scene returns to a high volume when the scene is quiet Broadcasting makes people irritated, so it is of great application value to provide a volume adaptive player that can reduce the volume output when the broadcasting site is quiet and automatically increase the volume when the site is noisy

Abstract

The invention discloses a volume self-adaptive player, comprising an audio signal source, an electronic gating switch, a balance circuit, a gain circuit, a power amplifier circuit, a loudspeaker, a noise sensor, an audio signal gain adjusting circuit, a processor, a display and input equipment. The audio signal gain adjusting circuit is used for receiving data of a noise sensor arranged on a broadcast site in real time, realizing gain adjustment of the gain circuit according to the data of the noise sensor, further realizing audio signal gain addition and subtraction, and achieving the purposeof adjusting the output volume of the power amplifier circuit. And different interfaces of the processor are respectively connected with the output end of the electronic gating switch and the controlend of the audio signal gain adjusting circuit, and are connected with a display and input equipment. The volume self-adaptive player has the advantages that the problems can be completely solved, the volume is low when quiet on site, and the volume is automatically increased when noise is miscellaneous.

Description

technical field [0001] The invention relates to a volume self-adaptive player, which can reduce the volume output when the broadcast site is quiet, and automatically increase the volume when the site is noisy, and belongs to the field of players. Background technique [0002] Existing broadcasting equipment in public places such as subways, airports, docks, etc., when the scene environment is noisy, the volume will be insufficient and affect the broadcasting effect. In order to improve it, the playback volume can only be increased, but the scene returns to high volume when the scene is quiet. Broadcasting makes people irritated, so it is of great application value to provide a volume adaptive player that can reduce the volume output when the broadcasting site is quiet and automatically increase the volume when the site is noisy. Contents of the invention [0003] The object of the present invention is to provide a volume adaptive player to solve the above-mentioned problem...
