发明名称 ELECTRONIC APPARATUS
摘要 Disclosed is an electronic apparatus which can ensure waterproofness or dustproofness when a rectangular electroacoustic transducer is employed, and can prevent both distortion of voice and leakage of sound at the same time. A first casing (101) of the electronic apparatus has sound holes (110). A film member (103) is substantially circular and provided between the sound holes (110) and an electroacoustic transducer (107). A planar member (105) is provided between the film member (103) and the electroacoustic transducer (107) and has second sound holes (111). The electroacoustic transducer (107) is substantially rectangular and generates voice.
