  The screw 182 holds the cushion 120 on the SP attachment member 140. The spacer 180 has a hollow pipe shape and is inserted into the four corners of the cushion 120, and a screw 182 passes therethrough. The spacer 180 is for preventing the cushion 120 from being directly pressed by the head of the screw 182 when the cushion 120 is held on the SP mounting member 140 by the screw 182. The speaker main body 110 generates a warning sound or a voice guide or the like to the operator by using an electric signal applied from a speaker amplifier (not shown) provided in the information processing apparatus 1 with the arrow 118 as a sound generation direction. At this time, the speaker body 110 vibrates.

The cushion 120 is an anti-vibration material for preventing vibration during sound generation generated in the speaker main body 110 from being transmitted to the SP mounting member 140.

Four corners of the frame 114 of the speaker body 110 are inserted into the four storage portions 125.

  Each flange 130 is formed one level lower (thin) in the depth direction than the frame 122, and each flange 130 is provided with a mounting hole 132 at the center. The attachment hole 132 is a hole through which a screw 182 for attaching the cushion 120 holding the speaker main body 110 to the frame 150 is passed. A spacer 180 is inserted into each mounting hole 132, and a screw 182 passes through the spacer 180. Details of the shape of the spacer will be described with reference to FIG.

  The speaker main body 110 is assembled to the cushion 120 by elastically deforming the flexible cushion 120 and inserting the four corners of the frame 114 of the speaker main body 110 into the storage portion 125. Thus, since the speaker main body 110 is held by the cushion 120 so as to be lightly supported at the four corners of the frame 114, it is possible to prevent the vibration of the speaker from being propagated to the cushion 120. Further, the core and the wiring 116 behind the speaker main body 110 are in a state of protruding to the back side of the cushion 120 through the opening 126.

  FIG. 10 is a diagram showing the external shape of the SP attachment member 140. FIG. 10A is a three-side view of the SP attachment member 140. The bottom is a front view of the SP mounting member 140, the top is a top view, and the next is a side view. FIG. 10B is a perspective view of the SP attachment member 140 as viewed from the rear side. In this embodiment, the SP attachment member 140 has shown the example comprised by combining the frame part 150 and the back attachment part 160 which were created separately. Specifically, in this example, the frame part 150 and the rear attachment part 160 are formed by bending a metal plate and joined by spot welding. Of course, the frame portion 150 and the rear mounting portion 160 may be formed integrally.

  The frame 150 is held so as to surround the outer shape of the speaker from the back side of the speaker body 110. As shown in the front view of FIG. 10 (A), the frame part 150 is shaped like a standing rectangular box with its front face being almost open and shallow in a posture such that its longitudinal direction is horizontal.
