Description

[Detailed Description of the Invention] The present invention relates to a speaker-equipped clock such as a panel clock or a wall clock that has a built-in speaker, and particularly relates to a speaker mounting structure thereof.

In general, panel clocks, wall clocks, and the like that use multifunctional clock integrated circuits that have the function of emitting alarms, time signals, etc. in addition to the clock function require a speaker as a sounding device in addition to the time display.

Conventionally, when installing this type of speaker, as shown in FIG. 1, an opening 2a is provided in the front surface 1a of an exterior case 1 of a panel clock or wall clock, and a small speaker 3 is inserted into this opening 2a. As shown in Fig. 2, the above-mentioned outer case 1
There is one in which an opening 2b is provided in the lower side surface 1b of the speaker, and a speaker 3 is attached to the opening 2b. However, in the former case, the sound is emitted from the front side of the outer case 1, so while it has excellent volume and sound pressure, on the other hand, the front side is decorated with various patterns to give it a decorative effect, so there are no openings. Another drawback was that the decorative effect was impaired by the loudspeaker. In addition, in the latter case, since the speaker 3 is attached to the side of the outer case 1, the decorative effect is not impaired like in the former case, but the thickness of the outer case increases according to the diameter of the speaker, and the outer case is It becomes difficult to make the case thinner, and the overall dimensions of the outer case increase, which is undesirable from a design standpoint.

In order to eliminate such drawbacks, as shown in FIG. 3, a speaker box is constructed in which the speaker 3 is housed in an upright position in an opening 2c provided in the lower side surface 1b of the outer case 1. 4 is attached and the sound is emitted from the side 1b. However, although this type of device can eliminate the above-mentioned drawbacks, it has the disadvantage that the sound quality deteriorates because it uses sound radiated from the back of the speaker.

The present invention has been made in view of these points, and its purpose is to provide a clock with a speaker that allows the outer case to be made thinner without impairing the sound quality or decorative effect.

In order to achieve this objective, the watch according to the present invention is provided with a vertically elongated speaker box formed to be able to accommodate a speaker between the partition plate and the back plate of the outer case, and An opening is provided on the side surface of the space, the front surface of the box facing the back plate is tilted to form a speaker mounting section, and a speaker is mounted on the mounting section, and sound emitted from the front surface of the speaker is extracted through the opening. This is how it was done.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 4 and 5 are a perspective view and a cross-sectional view taken along the line 1-2, respectively, showing an embodiment of the speaker box according to the present invention. In these figures, reference numeral 10 denotes a speaker storage section 11 formed to be able to store a speaker.
and an electronic component storage section 12 for storing electronic components such as batteries and operating members. It forms a mounting surface 13, and a speaker 14 is mounted on this mounting surface 13. Further, the electronic component storage section 12 is provided with a battery holder 15, and a ring stop switch 16 and a volume control volume 17 are respectively mounted on the bottom surface of the lower part of the battery holder 15. A mounting flange 18 is provided on the side surface of the speaker box body 10. Note that 19 is a mounting hole.

An embodiment in which the speaker box configured as described above is applied to a wall clock will be described with reference to FIG. 6. In this embodiment, a back plate 27 is detachably attached to an exterior case 25 of the wall clock, and a predetermined space is provided between the back plate 27 and the partition plate 26. Then, by arranging the speaker box 20 between the partition plate 26 and the back plate 27, and screwing the back plate 27 into the mounting hole 19 (see FIG. 4) of the speaker box 20,
The back plate 2
7, it is bent at a substantially right angle so as to come out from the lower side surface 25a of the exterior case 25. In addition,
In the figure, 28 is an opening provided in a portion of the lower side surface 25a of the exterior case 25 facing the space formed between the partition plate 26 and the back plate 27. Therefore, according to this mounting structure, since the back plate 27 is arranged on the front side of the speaker box 20, the direction of the sound coming out of the speaker box 20 can be bent in the vertical direction by the back plate 27. Even when sound is emitted from the lower side of the outer case, the outer case can be made thinner. By arranging an independent shielding plate on the front surface of the speaker box 20, the direction of the sound coming from the front surface can be changed from the horizontal direction to the vertical direction.

Although the above-mentioned embodiment shows a case where the electronic component storage section is integrally configured in the speaker box body in addition to the speaker storage section, the present invention is not limited to this, and the electronic component storage section can be omitted. You can also do that. Furthermore, the invention is not limited to wall clocks, but can also be applied to various clocks with built-in speakers.

As explained above, according to the clock of the present invention,
By adopting a structure in which a vertically elongated speaker box is arranged between the partition plate and the back plate of the outer case, the outer case can be made thinner without impairing the decorative effect of the watch. Additionally, since the sound is emitted from the front of the speaker, it has superior effects such as improved sound quality compared to conventional speakers emitted from the back.
