The smart grid construction stage will mainly drive the rapid development of China's power grid infrastructure equipment manufacturing, R&D and manufacturing of power automation products, R&D and service of power informatization technologies, R&D of power communication technologies and product manufacturing, and the market will face tremendous opportunities. According to CCID Consulting, a research institution, the scale of the industry driven by smart grid construction will be close to 2 trillion yuan between 2009 and 2015. The construction of smart grid will drive the rapid development of a series of related industries. The smart grid industry will promote the integration of various industries and promote the upgrading of regional industries. From the perspective of the industrial chain of the smart grid, each segment has different investment opportunities and access methods. In addition, the field of power value-added services and interactive terminals will be a category of industries that will grow along with the construction of smart grids, and will also be an important emerging market in the future.
Piezoelectric Buzzer For Driver Circuit Built-in
The piezoelectric buzzers (for Driver Circuit Built-in) offer optimal sound, performance, and efficiency for all types of medical and industrial applications. Our piezo buzzers are constructed in a variety of sizes and work across varying frequencies which allows them to produce different sounds and tones. As voltage is applied to a piezo Buzzer, the piezoceramic disc vibrates, flexing with respect to input voltage to generate sound. Our piezo buzzers maintain low current draw which is advantageous for any battery operated device. Since piezo buzzers don`t have a magnet in their construction, it eliminates EMI/EMC issues.
