Description

addressable volume controller

This creation discloses a addressable volume controller, which is electrically connected with the emergency sound source, business sound source, and sound source of a broadcasting host, and the two-wire communication signal is used to control the output power volume or cut of the audio source from the broadcasting host to the speaker. The transmission control of the cut-off sound source, the addressable volume controller includes a main panel, at least one volume adjustment button and a volume control transformer or resistance system, a microcomputer processing unit with two-wire communication signal connection and addressing, a computer Relay for signal control of the processing unit; among them, the volume controller has audio input such as emergency audio source, business audio source, and audio source. The business sound source is controlled by the volume controller's adjustment button to control the volume. The volume controller has a two-wire communication signal connection and a microcomputer processing unit for addressing; The sound source disconnection or multi-line function can control whether the speaker needs to output sound. Among them, the relay is electrically connected to the microcomputer processing unit. The microcomputer processing unit uses two-wire communication signals to connect to the broadcasting host. Group broadcasting and playing music; and when it is used for business broadcasting, when a fire occurs, the broadcasting host will switch the sound source to the emergency sound source output, the emergency sound source is not controlled by the volume controller, nor is it controlled by the disconnection of the relay, so this The volume controller can be used for fire emergency, and it can also be used for individual or group broadcasting or playing music at ordinary times.

Press, the volume controller commonly used in the general market only controls the volume of the business sound source, or combines the volume controller for fire emergency and business. It is generally used in hospital wards, breastfeeding rooms, conference rooms, offices, etc. where the volume of the sound needs to be adjusted. place.

However, when it is necessary to independently control or group control the sound source output of the speakers, a separate set of control boards is usually installed to switch the control sound source, so as to achieve the practice of outputting sound sources from a single speaker or a group of speakers. The most common example is the school's business teaching broadcasting Each classroom is equipped with a set of speakers and a set of controllers to control the audio output of the speakers. Its function is to turn on the controller of a classroom or group classrooms, and turn off the controllers of other classrooms, so that the function can reach individual broadcast or group The purpose of group broadcasting.

Based on the previous technologies above, if you need volume adjustment control and individual or group broadcasting functions, you need a set of volume controllers and a set of control panels to switch audio sources. In addition to the need for two sets of equipment, the cost of piping and construction costs is also doubled. Wages, costs, installation space, etc. are all multiple wastes.

In order to solve the above problems, this creation provides a addressable volume controller, which is electrically connected with the sound source and control signal of a broadcasting host, to control the output power volume of the audio source from the broadcasting host to the speaker or to cut off the transmission control of the audio source. The volume controller has emergency sound source, business sound source, and sound source input. The sound source can also be connected to the speaker independently. The emergency sound source is not controlled by the volume controller, while the business sound source is controlled by the volume controller. The adjustment button controls the volume; the volume controller has a two-wire communication signal connection and a microcomputer processing unit for addressing; it is also electrically connected to a set of relays, which have the function of controlling the disconnection or re-line of the business audio source, and can control whether the speaker is It needs to output sound, wherein, the relay is electrically connected to the microcomputer processing unit, and the microcomputer processing unit adopts two-wire communication signal to connect to the broadcasting host, and the broadcasting host can set individual broadcasting or group broadcasting and play music; It is also used for business broadcasting. When a fire alarm occurs, the broadcasting host will switch the sound source to the emergency sound source output. The emergency sound source is not controlled by the volume controller, nor is it controlled by the disconnection of the relay. Therefore, the volume controller can meet the fire emergency requirements. It can also be used as an individual or group broadcast or play music at ordinary times.
