Title: SEISMIC SOURCE, AND SEISMIC SOURCE APPARATUS AND DRIVING DEVICE THEREOF
Abstract:
Disclosed are a seismic source, and a seismic source apparatus and a driving device thereof. The seismic source comprises a base, a mounting plate, a first spring, a coil, a magnet, a magnetic alloy, and a weight block. The first spring connects the base with the mounting plate, such that the mounting plate is capable of reciprocating motion relative to the base. The coil is fixed to the base. One end of the magnet is fixed to the mounting plate, and the other end of the magnet extends into the coil. The magnetic alloy is fixed to the magnet. A gap is arranged between the magnetic alloy and the magnet to accommodate the coil. The weight block is fixed to the mounting plate. The seismic source apparatus comprises the above seismic source and an adjustable base. Compared with conventional electromagnetic seismic sources, the seismic source of the present disclosure has a simpler structure.
