An information transmission method using arc and apparatus thereof are applied to a loudspeaker and the like having the function of illumination. The information transmission method is characterized in that arc current supplied to an arc generating device is modulated by a signal based on information to vibrate arc column so that at least one of audible waves, ultrasonic waves and arc light is employed to transmit the information. Arc having small mechanical inertia is employed as a sound producing device and accordingly can be used as a loudspeaker having a good frequency characteristic and large output. It can be used as a sound producing device having the function of illumination by utilizing strong light emitted from arc column.

A connector engaging/disengaging mechanism comprises a frame member (3) and connector carriers (7) for engaging and disengaging first connector (40) mounted on a printed circuit board (5) fixed onto the frame (3) and second connectors (30) held on said connector carriers (7). The frame member is provided with guide grooves (11) in which the connector carriers (7) are received to be slidable in an engaging direction (A) and a disengaging direction (B). Each of the connector carriers (7) has connector holding portions for holding the second connectors and an operating portion (15) for moving the connector carrier to engage and disengage the second connectors (30) to and from the first connector (40). When the operating portion (15) is manually operated to move the connector carrier in the engaging direction, the second connectors (30) are connected with the first connectors (40). When the connector carrier is moved in the disengaging direction, the second connectors (30) are disconnected from the first connectors (40).

The present invention relates to a microelectromechanical device having a simple structure in which strains of the semiconductor substrate can be reduced. Both a semiconductor substrate 17 and a second substrate 14 are disposed to face a first main surface 13a of the first substrate 13 and connected to the first main surface 13a of the first substrate 13. With this structure, no internal line or side surface line is necessary, and the structure of the first substrate 13 can be simplified. The length of the line can be decreased to decrease the resistance of the line, and good electrical characteristics can be achieved at low energy consumption. The strains in the semiconductor substrate 17 can also be reduced.

In a connector comprising a housing (11) and a contact (21) held by the housing, the contact is brought into contact with a connection object under a pressing force obtained by operating an operating member (61). An elastic member (71) elastically deformable is interposed between the contact and the operating member. The operating member has a first cam surface (63a) for applying the pressing force to the contact with elastic deformation of the elastic member and a second cam surface (63b) for releasing the pressing force. An insulating actuator (51) cooperating with the contact may be interposed between the contact and the elastic member. The elastic member may be a leaf spring member held by the actuator.
