Abstract

Disclosed is a speaker unit which includes a provisionally fastening mechanism provided on a side surface of a cabinet section for provisionally fastening the speaker unit to a mounting part with at least a portion of the cabinet section inserted in an opening section of the mounting part from a face side of the mounting part. The provisionally fastening mechanism includes an engagement section for provisionally fastening the speaker unit to the mounting part, and a retention section for retaining the engagement section. The engagement section is movable between an engagement position in which the engagement section engages with the mounting part and a cancellation position in which the engagement section cancels the engagement with the mounting part by being moved away from the mounting part, and the retention section retains the engagement section in the cancellation position.

First claim

What is claimed is:

1 . A speaker unit for mounting to an opening section formed in a mounting part, comprising:
a cabinet section having a side surface and a bottom surface; a speaker surface provided in the bottom surface of the cabinet section; and a provisionally fastening mechanism provided on the side surface of the cabinet section and configured to provisionally fasten the speaker unit to the mounting part with at least a portion of the cabinet section inserted in the opening section from a face side of the mounting part, the provisionally fastening mechanism including an engagement section configured to provisionally fasten the speaker unit to the mounting part, and a retention section configured to retain the engagement section, the engagement section being movable between an engagement position in which the engagement section engages with the mounting part and a cancellation position in which the engagement section cancels engagement with the mounting part by being retracted from the mounting part, the retention section retaining the engagement section in the cancellation position.

2 . The speaker unit as claimed in claim 1 , wherein the retention section has a retention groove configured to retain the engagement section in the cancellation position, and a guide groove communicating with the retention groove and configured to guide movement of the engagement section between the engagement position and the cancellation position.

3 . The speaker unit as claimed in claim 2 , wherein the guide groove has a slant surface for gradually displacing a direction of movement, along the guide groove, of the engagement section, and
the retention groove extends from an end of the slant surface in a direction traversing the movement direction of the engagement section.

4 . The speaker unit as claimed in claim 1 , wherein the engagement section is formed on an intermediate portion of a resilient member whose one end is fixed to the cabinet section, and the engagement section is positioned in the engagement position or in the cancellation position in response to another end of the resilient member being operated manually by a human operator.

5 . The speaker unit as claimed in claim 1 , wherein the retention section is provided in association with an opening or a recess formed in a flange section projecting radially outward from an outer peripheral edge of the bottom surface of the cabinet section.

6 . The speaker unit as claimed in claim 5 , wherein the engagement section has a distal end projecting to a face side beyond the speaker surface.

7 . The speaker unit as claimed in claim 5 , wherein the engagement section has a distal end disposed retracted from the speaker surface in a direction toward a reverse side of the mounting part without projecting to a face side beyond the speaker surface.

8 . The speaker unit as claimed in claim 1 , wherein a plurality of the provisionally fastening mechanisms are provided on an outer periphery of the cabinet section.
