Abstract: Provided is an electronic controller which enables visual identification of a portion applied with a small amount of a sealing material, which has a high possibility of air leakage from an area in which a joint is to be established. The electronic controller includes: an electronic circuit board; and a casing including a cover (1), a base (4), and a lid sealed with a sealing material (20) applied to surfaces thereof at which the cover (1), the base (4), and the lid are to be joined together. An area in which the cover (1), the base (4), and the lid are to joined together is provided with a space (16) thereto for enabling an application state of the sealing material (20) to be observed with a naked eye.

Abstract: Provided is an electronic controller, which allows the use of a general-purpose connector, and does not require setting of a case for housing an electronic circuit board therein for respective connectors each having a different shape so as to enable a reduction in cost. An electronic controller (1) includes: an electronic circuit board (2) onto which an electronic component (16) is mounted; a connector (3) provided at an end of the electronic circuit board (2); a case (6) housing the electronic circuit board (2) therein and including an opening portion (6a) on a side of the connector (3); and a connector retaining member (4) provided between the connector (3) and an inner wall surface of the opening portion (6a) so as to be held in close contact with the inner wall surface and to surround the connector (3).

Abstract: A body-acoustic device is provided which comprises a housing (1), a diaphragm (4) dividing an inner space of the housing into a first chamber (5) and a second chamber (6), and a loudspeaker (7) mounted to an opening provided in the diaphragm, wherein the diaphragm is made of a transversely vibratory member and/or has a perimetric edge supported by an inner surface of the housing via an elastic member (10), and wherein the diaphragm (4) is further provided with a port (9) for air movement between the first and second chambers (5), (6). When the loudspeaker (7) is operated, the diaphragm vibrates with a cone paper (8) to generate sufficient heavy bass sound with high sound clarity as if the diameter of the loudspeaker had increased. The port provided in the vibrating diaphragm facilitates the vibration of the diaphragm, further increasesing the sound pressure created by the diaphragm vibration due a sound throttling effect caused by the port.
