We often use headphones to listen to music, or make it more convenient to answer mobile phones, but no matter what size of headphones, they are worn on the ears. Now there is a very special broadcast tool, not on the ear, but on the rim of the cap. When you put on the hat, the sound will be transmitted to the inner ear through the skull audio (Bone ConducTIon) with vibrating audio. You can also hear the music played by your mobile phone, and you can answer the phone and answer with ease!
Cynaps (Cynaps Connect), launched by Max Virtual, is a broadcasting tool that does not need to conduct sound through the ear. It communicates with the mobile phone via a Bluetooth interface. The main body is a control panel with a few centimeters square. The transmission line is connected to the surface, and the tiny sensor is connected. The sensor is installed in the non-woven side of the hat. When the sensor vibrates, the head will feel audio vibration. What is amazing is that during the transmission of audio You can hear the sound and music it conveys.
Cynaps is equipped with a microphone. There are three buttons on the main body to provide functions such as controlling volume, playing / pausing music, answering calls and ending calls. When you use it, you can clearly hear the sound, while others can only hear a slight buzzing sound, which is very similar to the weak noise when using a small radio to listen to AM broadcasts.
Cynaps can help users to discard the earphones and other devices in the ear, and give the ear space to other external sounds. For example, when riding a bike, you may need to listen to the surrounding sounds to judge the road conditions and improve safety. If Van Gogh is still alive, he can use Cynaps to listen to beautiful music! Of course, ethnic groups with heavy hearing problems can be expected to benefit from Cynaps.
In addition to listening to music and answering phone calls, Cynaps can also support Apple's Siri application. In the future, Google's mobile wearable devices may also be combined with Cynaps to make sound more powerful. Max Virtual has launched an exclusive designed hat on its official website to sell with Cynaps. There are also separate Cynaps combinations available for purchase. Tired of wearing headphones? Buy a set of Cynaps on your favorite cap!
Piezoelectric Ceramic Ring
Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
