Abstract: According to one of aspects, provided is an electronic device including a panel 10, a piezoelectric element 30 attached to the panel 10, and a substrate 25 attached to a main surface of the piezoelectric element 30. The panel 10 is configured to be deformed due to deformation of the piezoelectric element 30, and sound is transmitted to an object that is in contact with the deformed panel 10. The substrate 25 includes a base 25a made of resin, and signal lines 25b and 25c laminated with the base 25a and connected to the main surface of the piezoelectric element 30. The substantially the entire main surface of the piezoelectric element 30 is covered by the base 25a.

Abstract: An electronic apparatus includes: a first circuit board having a mounting surface; a shield casing disposed so as to face the mounting surface of the first circuit board and cover an electronic component mounted on the mounting surface; a battery disposed so as to face the shield casing at a position next to the first circuit board in a first direction which is parallel to the mounting surface of the first circuit board; and a first rib provided on a surface of the shield casing so as to extend in the first direction, one end of the first rib being disposed at a position corresponding to the first circuit board in a second direction, the other end of the first rib being disposed at a position corresponding to the battery in the second direction, the second direction being perpendicular to the mounting surface.

Abstract: A portable electronic device includes a cover, and a casing engaged with the cover to form a space between the cover and the casing. The portable electronic device also includes a first mounting substrate in the space and an electroacoustic transducer between the first mounting substrate and the casing. The electroacoustic transducer converts from one of an audio and an electric signal into the other.

Abstract: A portable telephone 1 is a portable terminal device in which a telephone receiving housing 2 is coupled to a telephone transmitting housing 3 by a coupling portion 4 such that they can be opened and closed. In the telephone receiving housing 2, a projecting portion 21 is formed on an end portion of a first face S1, which faces the telephone transmitting housing 3 in the closed state. In the telephone transmitting housing 3, a notched portion 22 is formed in an end portion thereof, in which the projecting portion 21 is arranged such that the projecting portion is rotatably coupled to notched portion 22. A switch is provided inside the projecting portion 21 and a sub-key capable of depressing this switch is provided to the projecting portion 21. The sub-key is provided on a surface of the projecting portion 21 in such a manner that a depression direction of the sub-key coincides with a depression direction of the main key in the opened state.
