Abstract

Disclosed is a speaker unit which includes a speaker surface provided in a bottom surface of a cabinet section and a provisionally fastening mechanism provided on a side surface of the cabinet section. The provisionally fastening mechanism includes: an engagement section for provisionally fastening the speaker unit to the mounting part; an operating section exposed on a face side of a mounting part with the speaker unit provisionally fastened via the engagement section; and a non-shielded portion formed adjacent to the outer periphery of the speaker surface for allowing the operating section to be visible from a face side of the speaker surface. The non-shielded portion is an opening or a recess formed in a flange section projecting radially outward from the outer peripheral edge of the bottom surface of the cabinet section.

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;
an operating section exposed on the face side of the mounting part with the speaker unit provisionally fastened to the mounting part via the engagement section; and
a non-shielded portion formed adjacent to an outer periphery of the speaker surface for allowing the operating section to be visible from a face side of the speaker surface.

2 . The speaker unit as claimed in claim 1 , wherein the non-shielded portion is 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.

3 . The speaker unit as claimed in claim 1 , wherein the operating section projects to the face side beyond the speaker surface.

4 . The speaker unit as claimed in claim 1 , wherein the operating section is disposed retracted from the speaker surface in a direction toward a reverse side of the mounting part without projecting to the face side beyond the speaker surface.

5 . The speaker unit as claimed in claim 1 , wherein the non-shielded portion is a retention section that retains the operating 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 engagement with the mounting part by being retracted from the mounting part, and the retention section retains the operating section in the cancellation position of the engagement section.

6 . The speaker unit as claimed in claim 5 , wherein the retention section has a retention groove configured to retain the operating section when the engagement section is in the cancellation position, and a guide groove communicating with the retention groove and configured to guide movement of the operating section when the engagement section moves from the engagement position to the cancellation position.

7 . The speaker unit as claimed in claim 6 , wherein the guide groove has a slant surface for gradually displacing a direction of movement, along the guide groove, of the operating section, and
the retention groove extends from an end of the slant surface in a direction traversing the movement direction of the operating section.
