Provided is a transducer that can be attached to a desired position and removed therefrom and that does not damage musical instruments. A first magnet member (32) and a second magnet member (34) are mutually attracted toward one another by magnetic force across the top board of a ukulele. Thus, a receiver unit (30) including a piezoelectric element (36), which is supported by the first magnet member (32), can be positioned at a desired position. Because the receiver unit (30) is kept in position only by the mutually attracting magnetic forces, the receiver unit can be moved to any desired position even after once being positioned on the top surface of the ukulele. |
