According to one of aspects, provided is an electronic device including a panel, a piezoelectric elementattached to the panel, and a substrateattached to a main surface of the piezoelectric element. The panelis configured to be deformed due to deformation of the piezoelectric element, and sound is transmitted to an object that is in contact with the deformed panel. The substrateincludes a basemade of resin, and signal linesandlaminated with the baseand connected to the main surface of the piezoelectric element. The substantially the entire main surface of the piezoelectric elementis covered by the base

Unit, electronic device, and method of manufacturing electronic device

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.

Electronic apparatus

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.

Portable electronic device and portable telephone with electroacoustic transducer mounting

A portable telephoneis a portable terminal device in which a telephone receiving housingis coupled to a telephone transmitting housingby a coupling portionsuch that they can be opened and closed. In the telephone receiving housing, a projecting portionis formed on an end portion of a first face S, which faces the telephone transmitting housingin the closed state. In the telephone transmitting housing, a notched portionis formed in an end portion thereof, in which the projecting portionis arranged such that the projecting portion is rotatably coupled to notched portion. A switch is provided inside the projecting portionand a sub-key capable of depressing this switch is provided to the projecting portion. The sub-key is provided on a surface of the projecting portionin such a manner that a depression direction of the sub-key coincides with a depression direction of the main key in the opened state.
