Abstract
PURPOSE: To achieve further small size, by using a speaker consisting of a transparent sound body for the window of a cassette cover and commonly using it as the window for tape residual amount confirmation.
CONSTITUTION: A cassette cover 3 is provided freely in opening and closing at a cassette chamber 2 of a tape recorder main body 1 with a hinge 31. The cassette cover 3 is provided with a window 4 in common use for speaker and tape residual amount confirmation inserting a piezoelectric film 42 being a curved transparent sound body. Transparent electric films 422, 423 are coated at both sides of the film 42 and they are connected to an electric circuit when the cover 3 is closed via a lead 424. Thus, a space for a speaker is not provided especially and the size of recorder main body can remarkably be reduced.
