the benefits of technical improvement of elevator station announcer
1、Played audio with moderate speech speed and high information capture
It not only guarantees the realization of elevator station announcer's basic function, but also saves the storage medium in the existing technology because of its low storage capacity, which further saves the cost, thus greatly reduces the cost of elevator voice station announcer.
2、Reduce the cost of the whole elevator voice station announcer
Further understanding shows that the elevator station announcer also includes circuit board, bottom and front panel; communication processing chip, PCM voice chip and level input port are integrated on the circuit board; circuit board is fixed on the bottom shell; loudspeaker is fixed on the front panel. The design method of this structure is simple and easy to realize. It can also save the cost of mechanical materials and further reduce the cost of the whole elevator voice station announcer.
3、Appropriate sound decibel control will not cause noise pollution
It is worth mentioning that in the implementation of the elevator station announcer, if the volume of the elevator voice station announcer is too small, the human ear may not be able to recognize, if the volume of the play is large, it is more noisy. Therefore, it is very important to control the volume of the elevator station announcer in a suitable decibel. In the actual test process, technicians found that if the volume is controlled at the appropriate decibel, the human ear can still respond when sampling at a lower frequency.
