Visual inspection of electronic components

Micro speaker technology in all areas of rapid development and innovation to the electronics industry has brought a huge market demand and development space, thus piezo buzzer the strong development of the electronic components industry, and electronic components intelligent, integration and magnetic buzzer tovisual inspection of electronic components makes it difficult. Traditional manual inspection is limited by visual inspection is slow, inefficient and vulnerable workers experience and physical mechanical buzzer and other subjective factors, has been unable to meet the needs of businesses are Standing Inductor expanding production capacity.

The development and change of speaker

In 1923, Bell Labs decided to micro speaker the perfect music reproduction system, including new player and speakers, stereo recording with MC phono, piezo buzzer carved piece way, was invented in the wave action. The heavy responsibility of the R & D speakers, two engineers who falls CW Rice and EW Kellogg. The equipment used were never seen before, including a 200-watt vacuum tube amplifier, many Bell Labs recordings magnetic buzzer, over the years, Bell Labs mechanical buzzer a variety of speakers - like Lodge cone speaker prototype, compressed air compressed air horn and corona discharge speakers (called ionizing drive), and electrostatic Standing Inductor diaphragm valve control.
