Installation structure for acoustic transducer

摘要

An installation structure for an acoustic transducer configured to push and pull a vibrated body and having a magnetic-path forming portion; a vibrating unit; and a connector having at least one joint portion configured to connect two members such that axes of the two members are inclined relative to each other by bending at the at least one joint portion, the at least one joint portion having an urging portion configured to generate an urging force by which a pushing-side driving portion of a first member connected to one side of the at least one joint portion urges a pushing-side driven portion of a second member connected on another side of the at least one joint portion in a pushing direction and an urging force by which a pulling-side driving portion of the first member urges a pulling-side driven portion of the second member in a pulling direction.

主权项

1. An installation structure for an acoustic transducer configured to operate in accordance with an audio signal and to push and pull a vibrated body in predetermined directions for thereby vibrating the vibrated body, so as to permit the vibrated body to generate sounds, comprising:
a magnetic-path forming portion fixedly disposed relative to a fixedly supporting portion and forming a magnetic path; a vibrating unit having an electromagnetic coupling portion electromagnetically coupled to the magnetic-path forming portion, the vibrating unit being configured to vibrate in the predetermined directions when the electromagnetic coupling portion is driven by the magnetic-path forming portion in response to a drive signal based on the audio signal; a connector having at least one joint portion configured to connect two members such that axes of the two members are inclined relative to each other by bending at the at least one joint portion, the connector connecting (a) a part of the vibrated body or a fixed portion fixed to the vibrated body and (b) the vibrating unit, wherein a first member that is connected to the at least one joint portion on one of opposite sides thereof nearer to the fixedly supporting portion is provided with a pushing-side driving portion to drive the vibrated body in a pushing direction of the predetermined directions and a pulling-side driving portion to drive the vibrated body in a pulling direction of the predetermined directions, wherein a second member that is connected to the at least one joint portion on the other of the opposite sides thereof nearer to the vibrated body is provided with a pushing-side driven portion to be driven by the pushing-side driving portion in the pushing direction and a pulling-side driven portion to be driven by the pulling-side driving portion in the pulling direction, and wherein the at least one joint portion has an urging portion configured to generate an urging force by which the pushing-side driven portion is urged by the pushing-side driving portion in the pushing direction and an urging force by which the pulling-side driven portion is urged by the pulling-side driving portion in the pulling direction.
