Children's incorrect sitting posture can easily cause fatigue of the neck muscles, causing neck and shoulder pain, neck muscle spasms, and even dizziness; over time, cervical disc degeneration is bound to occur prematurely in adulthood, leading to cervical spondylosis.
Many people are worried about this. Children's affairs are more important than anything else. This is the general idea of many parents. Parents pay more attention to things related to their children's learning, such as: vision protection, sitting posture when studying, etc.
Many children take online classes at home, and some parents are "scratching their heads" when faced with their children's crooked sitting postures. Facing the confusion shared by many parents, the "children's sitting posture corrector" is currently on the rise. Parents can use the sitting posture corrector as an auxiliary reminder to help their children maintain a good sitting posture.
So how does the children's sitting posture corrector achieve the voice prompt function?
The core is the voice prompt chip, NV040D voice chip, which is a stable voice chip launched by Jiuxin Electronics. It does not require any peripheral circuits and can work normally in extremely harsh noise environments. It has a wide temperature and voltage resistance range, and the normal working range is as wide as 2V~5.5V, which makes up for the poor anti-interference ability of voice chips on the market. There is a set of PWM output ports that can directly drive 0.5w speakers with clear sound quality. Built-in LVR reset, no external reset circuit is required.
Built-in precise internal frequency oscillator (+-1% error), no external resistors are required. Another obvious advantage is that the OTP burning program can be seamlessly connected with the MASK mask, that is, users can conduct OTP trial production in the early trial production stage of the product, and when entering large-scale production after the trial production is successful, the MASK mask can be directly put into production according to the OTP sample to reduce costs, and customers do not need to confirm the sample twice.
The NV040D voice chip has multiple key triggering modes and can output multiple forms of level signals, which can be set to change according to the ups and downs of the voice. In addition, NVD supports the main MCU serial port control, and can arbitrarily control multiple voice triggers. It is the only 8-pin chip on the market that can support 223 voice segments.
The NV040D voice chip is also a deeply customized product. It is a low-cost solution developed specifically for the field of custom voice playback. The corresponding model can be selected according to different functional needs.
It can customize voice solutions within 40 seconds, while the NV080D, NV170D, and NV340D voice chips in the same series can achieve voice solutions within 80 seconds, 170 seconds, and 340 seconds. You can choose the appropriate voice chip model according to different voice duration requirements.
NV040D voice chip application voice solution in children's sitting posture corrector (voice content can be customized):
1. Welcome to use XXX children's sitting posture corrector;
2. Protect your eyesight and pay attention to good sitting posture;
3. Please maintain a good sitting posture when studying;
4. When reading, please pay attention to the rules of one foot, one fist, and one inch;
5. Don’t set it too low;
6. Sit up straight, don't lie down;
7. The reminder to sit upright is turned on;
8. Sitting posture reminder is turned on;
9. The sitting posture reminder is turned off;
10. ......;
