Based on the factory area network, it has the function of spanning the INTERNET network:


The whole system requires simple wiring, making full use of the existing factory network in the factory area. The terminal is directly connected to the factory LAN in the factory area, and only the audio cable from the terminal to the speaker needs to be arranged. The wiring is simpler and more convenient than any other form of broadcasting.



Background Music Overview

* Factory public area design digital IP background music PA system

* Each zone play background music independently, providing notification for factory employees and creating a comfortable working atmosphere for the office area; realize music selection and volume adjustment through mobile APP.

Public area: The factory corridor is designed with ceiling decoration, so the ceiling speaker is adopted in the public corridor, the power is 6W, and the installation distance is 8-10 meters.


1. The distribution spacing of ceiling speakers (as shown in the figure)

The size of the spread angle can determine the distribution spacing of the speaker.

S1=2×(H-h)×tan(Q/2)

S2=4×(H-h)×tan(Q/2)

Among them, S1: the minimum reference value of the distribution spacing

S2: the maximum reference value of the distribution spacing

H: ceiling height

h: set listening height

Q: the spread angle of the speaker.


Production workshop: a workshop has a separate zone. According to the site environment noise, meet the sound pressure level requirements of the background music and be more than 12dB higher than the site environment noise; set up horn speakers, and arrange one horn about 20 meters apart.

1. The distribution spacing of wall-mounted speakers (as shown in the figure)

The size of the spread angle and sound pressure level determine the distribution spacing of the speaker.

S1=R×sin(Q/2)

Among them, S1: the minimum reference value of the distribution spacing

R: distance between the speaker and where the sound pressure level is 80dB

Q: the spread angle of the speaker
