Abstract

The invention discloses a sound effect control and alarm device and belongs to the information technology field. The device comprises a main control system, a sound absorption system, a water spray system, a sound equipment, a smoke sensor, and a sound sensor installed on the sound absorption system. The sound absorption system is used for absorbing sounds with different frequencies. The sound sensor is used for collecting sound information. The smoke sensor is used for collecting smoke concentration information. The main control system adjusts a volume of the sound, an audio frequency, a sound effect and a channel of the sound according to the sound information, and transmits the adjusted sound to the sound equipment. The main control system starts a backup power supply according to smokeconcentration information, opens an emergency exit, and issues emergency information. The sound equipment is used to output the adjusted sound and the emergency information. The water spray system automatically sprays water to put out a fire according to the emergency information. In the invention, a best hearing environment is created for people, the device is suitable for different environmentsand a resource occupation problem is solved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a sound effect control and alarm device. Background technique [0002] At present, the various parts of sound effect monitoring and control in different scenes and environments commonly seen on the market are independent of each other, and require human control, and have not realized real intelligence. When running into an emergency situation, it cannot be conducive to people's escape, and it is also very easy to cause large-area combustion of inflammable materials. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a sound effect control and alarm system to solve the problems in the prior art that the sound effect of meeting rooms and other places is not good, and it is very easy to cause flammable fires in case of emergency. The problem of burning large areas. [0004] In order to solve the...
