The present invention is directed to a device for producing a shock wave to impact an object that includes a transfer member. The device has a voice coil assembly including a permanent magnet and a bobbin member, wherein the permanent magnet provides a first magnetic field. A hammer is attached with the bobbin member; and a coil is operatively attached to the bobbin member, wherein when a voltage is applied to the coil a second magnetic field is generated that opposes the first magnetic field and thereby propels the hammer to contact the transfer member to cause a shock wave to travel along the transfer member. The present invention is also directed to a method for producing a shock wave, that includes the steps of providing a transfer member; providing a voice coil assembly including a permanent magnet and a bobbin member; providing a first magnetic field providing a hammer attached with the bobbin member; providing a coil operatively attached to the bobbin member; and applying a voltage to the coil to generate a second magnetic field that opposes the first magnetic field thereby propelling the hammer to strike the transfer member.
