The automatic curler has three classic hairstyles: natural wave, soft curl, and fashionable charm, and a variety of DIY combinations. In addition, the automatic hair curler sets the temperature, time and direction through the system, so that the curling design can be controlled throughout the whole process. It also has a balanced heating design for natural and perfect curling, a design that does not hurt the hair quality, a humanized anti scalding face design, an intelligent work safety and anti electric shock design, a fully automatic system design, a sensor design that does not tangle or pull the hair, does not pinch the hair, and a design that has a life span of more than 10 years, Definitely ended the traditional curling tools.

Overview: (This product has been discontinued, and there are other new upgraded products with the same function, you can consult our customer service) WTN4 series voice chips are a series of voice chips launched by Shenzhen Weichuang Zhiyin Electronics Co., Ltd., with superior performance and affordable prices. This series of chips includes WTN4045, WTN4065, WTN4105 (the speech length is 45s, 65s, 105s when sampling at 6KHz) and other speech chips. WTN4 is a multi-functional single chip CMOS voice synthesis 4-bit controller. It provides a channel of voice output, with a set of high-quality PWM to push the horn directly. High quality ADPCM algorithm is adopted for speech synthesis, and the highest audio sampling rate can reach 44.1KHz+/- 1% internal oscillation, no need to add external oscillation, with ultra-low power standby. Function description: ☆ Working voltage: 2.4V~5.5V; (The chip should be set to 3.3V or 5V according to the power supply voltage, which will be explained later). ☆ With standby mode, power consumption can be saved, and the static current is less than 1uA. ☆ PWM pure audio output can directly drive 8 Ω/0.5W horn and buzzer. ☆ High quality ADPCM speech synthesis algorithm can improve the sound quality by simply adjusting the sampling bits. ☆+/- 1% internal oscillation, built-in low-voltage reset (LVR=1.8V) and watchdog, supporting BUSY status output function. ☆ One line serial port control mode and two line serial port control mode are available; Digital pulse control mode. Application examples In terms of chip application scope, it can almost involve low-cost voice places without changing, such as: ☆ cars (anti-theft alarm, reversing radar, GPS navigator, electronic dog, central locking); ☆ Smart home system, alarm clock and reminder; ☆ Special alarm, household anti-theft alarm; ☆ Medical device voice prompt and therapeutic apparatus; ☆ Home appliances (induction cookers, rice cookers, microwave ovens); ☆ Entertainment equipment (game machine, amusement machine); ☆ Learning model (early education machine, children's audiobooks); ☆ Intelligent transportation equipment (toll station, parking lot); ☆ Communication equipment (telephone exchange, telephone set); ☆ Industrial control field (elevator, industrial equipment);
