Abstract
A transducer includes a housing, a magnet unit, an elastic diaphragm, a vibration unit, and a coil. The housing has a first housing and a second housing to form a storing space. The magnet unit is secured in the first housing. The elastic diaphragm is a thin layer and disposed between the second housing and the vibration unit. The spiral coil is mounted on the vibration unit and has two electrical connecting points for inputting electric signal of alternating current. Hence, the coil can generate continuous vibration caused by alternating attraction/repelling force of the magnet unit. When the frequency of the electric signal is within 20˜20000 Hz, the elastic diaphragm generates sound signals within earshot. When it is within 10˜20 Hz, it can generate vibration signals. So, signal unit can produce sound and vibration. In addition, it saves space for effectuating the thickness minimization of a product.
