1. IntroductionThis is a voice announcer for elevator,actually, not only as a elevator floor voice announcer, lift voice indicator, but also as a elevator floor voice advertiser. Adopt high-performance single chip and professional voice chip. Support MP3 audio format, adopt the altitude sensor, easy to installation and can detect the working condition of the elevator then play the voice. You can freely replace voice files via U disk. It has been widely used in elevator floor announcement, floor voice navigation, sightseeing elevator/ cable car specific scenic spots, public security warning and other occasions. WT-50800G elevator floor announcer can detect elevator up or down, which floor arrive and automatically remind passengers when elevator goes up/ down to the 1st/ 2nd/ 3rd/ ...
Product Description:Body induction is a kind of technology that infrared pyroelectric principle is used to induce the body activity information. When a person enters the sensor's effective range, the information will be accurately identified and detected. It is like a cat's eyes, not rely on the light. Even in the dark environment, it can work normally, overcoming the deficiencies of the light sensor. PowerSound body induction voice prompter is one of the body induction prompt devices, supporting DIY function, MP3 audio format, offline download, with high-power speaker. For your better understanding of the product installation and configuration process, please carefully read this manual. Electric Parameter:☆Using infrared induction technology.☆The sens...
WTR030 is a multifunctional voice record & playback chip, specially designed for recording voice. It integrates many external circuit components: 16bitADC/DAC, microphone OPA amplifier, 16bit encoder, etc..Can record in long distance, high definition, built in LDO3.3V output supplying power for flash, and built in 1W power amplifier able to directly drive the speaker.

Product Description:WTN7 voice ICs are similar with WTN6 sound chip.There are two kinds now (WTN7080,WTN7170 ); the voice length is 80s and 170s, much longer than WTN6 sound chips (WTN6 voice length is only 40s), both package are sop8 and dip8 pin.The audio sample rate can up to 44.1kHZ maximally,16-level volume control.WTN7 chip output mode is PWM, without DAC output. But WTN6 voice IC chip has both PWM and DAC output.PWM output can drive 8R/0.5W speaker, Accurate +/-1% internal shock, no need to have external shock, super-low power consumption in standby mode. Functions:△Working voltage: 2.8V~5.2V.△Long voice length, 80s and 170s for option.△In standby mode, quiescent current less than 5uA.△Accurate+/-1% ...
