Abstract: A circuit pattern on the surface of a printed circuit board used as a guide and connection circuit for closely spaced contacts of a connector to be connected to the circuit board. The contacts of the connector are closely spaced and possibly would not contact the connection pads (80) or might be located between connection pads (80) because of the close spacing of the contacts. The guides (70) formed from circuit patterns accurately guide the connector to the connector pads (80) on the circuit board and place each contact over its respective circuit connection pad.

A second sensor (26) detects sound at the object point and converts them to electric signals which are inputted to the signal processor. The signal proc­essor switches the control mode, in accordance with a predetermined condition, to an adapting active control wherein the factor series is changed in response to the electric signal applied from the second sensor or an active control wherein the factor series is fixed.
