Abstract: In order to ensure communication performance, a weight measuring device 1 includes a weight measurer configured to have a measurement target object placed thereon and measure a weight of the measurement target object, a communication module configured to transmit a measurement value of the weight of the measurement target object measured by the weight measurer by wireless communication, and an arrangement unit formed in an upper part of the weight measurer, the arrangement unit being configured to have at least an antenna of the communication module disposed on an upper side of the weight measurer.

Abstract: The electronic device can effectively suppress a reduction in sound pressure and an increase in the distortion factor. The electronic device (1) includes a piezoelectric element (30), a panel (10) supporting the piezoelectric element (30), and a housing (60) holding the panel (10). The electronic device (1) causes the panel (10) to generate air-conducted sound and vibration sound that is transmitted by vibrating a part of a human body. A buffer material (90) is disposed between the panel (10) and the housing (60).

Abstract: Provided is an electronic device 1, including: a piezoelectric element 30; a panel 10 configured to support the piezoelectric element 30; and a housing 60 configured to hold the panel 10 and conduct a vibration through the panel 10, the panel 10 generating air-conduction sound and vibration sound that is transmitted by vibrating a part of a human body. The housing 60 includes a first housing portion 62 and a second housing portion 61 located inward of the first housing portion 62, and rigidity-reinforcing portions (63, 150; 64, 160; 65, 66, 170) are disposed between the first housing portion 62 and the second housing portion 61 for improving rigidity of the housing 60.
