FILM TYPE SPEAKER WITH FETAL EDUCATION FUNCTION

摘要

PURPOSE: A film type speaker which includes a prenatal education function is provided to use a microphone connected with a film speaker unit and external sound source device, thereby inducing communications between a fetus and mother. CONSTITUTION: A film type speaker with a prenatal education function includes a film speaker unit(100), a stethoscope(200), and a controller(300). The film speaker unit covers the abdomen(400) of a mother. The film speaker unit generates sound pressure by vibrating both surfaces using a current applied from the outside and transmits vibrations, voice, or acoustic sound to a fetus. A fixing stand is prepared in both edges of the film speaker unit in order to prevent the separation of the film speaker unit from the abdomen of the mother. The controller electrically connects the film speaker unit with a microphone(500) or external sound source device(600). An earphone(700) is electrically connected to the stethoscope.
