Medical Grade Certified Buzzer Invention Patent

Feature: Developed this buzzer according to IEC60601-1-8 requirement. We are the first company in China offer this buzzer.

This product has a low frequency of 300-1KHZ. Based to the requirements of IEC60601-1-8, a special alarm sounds of more than 4 harmonics must be achieved, and there is a gradient sound function. In order to achieve this sound effect, the general practice in the market is save the pre-recorded voice module into the buzzer and play it out. But this method is too expensive and only limit to one sound/one design. Our company developed the audio software independently by using a single IC, through software, we can interchange the different type of sound/alarm.
