Abstract: PURPOSE:To decrease the nonlinear distortions to the sound signals and to improve the sound quality by using a transformer and a current/voltage converting circuit and therefore reducing the apparent value of both the internal resistance and the load resistance of an electromagnetic converter. CONSTITUTION:An electromagnetic converter 1 scans with rubbing the sound groove of a record, for example, by a stylus chip attached at the tip of a cantilever and generates the electric power by changing the magnetic flux of a magnetic circuit in response to the mechanical vibrations of the cantilever. Thus the converter 1 reproduces the sound signals. The sound signals obtained by the converter 1 are supplied to the primary winding of a transformer 2 which has the ratio of numbers of turns set at n:1 (n: real number larger than 1) between the primary and secondary windings. Then the current transformation is performed with the transformer 2 so that the sound signal current flowing to the secondary winding is larger than that flowing to the primary winding. The sound signal current extracted from the secondary winding of the transformer 2 is supplied to a current/voltage converting circuit 3 and converted into the sound signal voltage. This voltage is delivered through a terminal 4 and supplied to a circuit of the next stage such as a preamplifier, etc.
