Description

[Detailed description of the invention] This invention relates to a small portable speaker with a stereo reproduction method, and allows a pair of speaker units to be folded into a compact state from the left and right unfolded state, making it easy to store and carry when not in use. The primary purpose is to facilitate convenience. A second purpose is to allow the device to be hung not only on a horizontal surface when in use, but also on a vertical wall or other arbitrary location.

To explain the details based on the drawings, FIGS. 1 to 7 show one specific example of the small speaker according to the present invention, in which a pair of left and right speaker units 1, 1 are connected via a hinge 2. Each speaker unit 1 has a speaker body 4 built into a rectangular speaker box 3, and a punching metal 5 facing the speaker body 4 is stretched on the front surface of the speaker box 3. . The left and right speaker units 1, 1 connected by a hinge can be opened and closed from a closed position in which the front surfaces having punched metals 5, 5 overlap each other to an open position in which they are expanded 180 degrees to the left and right. When the left and right speaker units 1, 1 are in a closed state, the closed state is maintained by the concave-convex fitting between the convex portion 6 provided on one speaker box 3 and the concave portion 7 provided on the other speaker box 3. Ru. The means for maintaining this closed state can be modified in various ways, such as using other latching means or magnetic adsorption on the mating surfaces.

In a speaker having such a basic structure, the present invention provides a hook for hanging and supporting an object, specifically, a sun visor 8 in a car, as shown in FIG. It is characterized in that a stopper 9 is attached to the speaker.

In FIGS. 4 and 5, this latch 9 is obtained by sheet metal pressing of a metal plate or by plastic molding, and the base end of a flat plate 10 is attached to one speaker unit 1. It is pivotally attached to the rear wall of the box via a support shaft 11 so as to be rotatable around the support shaft 11. In the illustrated example, a hook portion 13 having an engagement hole 12 is formed at the base end of the plate body 10, and an elastic clamping piece 14 is integrally bent and formed at the distal end side of the plate body 10. An engaging protrusion 15 is protruded from the rear wall of the box of the other speaker unit 1, and when both speaker units 1, 1 are expanded and the latch 9 is raised, the hook portion 13 engages with the engaging protrusion 15. Both speaker units 1, 1 are maintained in the expanded state by engaging with the protrusion 15, and in this state, the entire speaker can be latched and supported on the sun visor 8 via the latches 9.

That is, when storing and carrying the present speaker when not in use, the left and right speaker units 1, 1 are compactly closed together via the hinge 2 so that their front surfaces overlap, as shown in FIG. When using both speaker units 1, 1
is expanded to the left and right with a predetermined opening angle. As a result, as shown in FIG. 3, a stereo reproduction state is established in which both the speaker units 1, 1 are spaced apart from each other to the left and right and are parallel to each other. Generally, indoors, the speaker of the present invention in this unfolded state will be placed as it is on a horizontal surface. In that case, the latch 9 does not perform its original function.

When the speaker of the present invention is to be supported by being latched to the sun visor 8 in a car, the left and right speaker units 1, 1 are unfolded at 180 degrees, and the latching tool 9 is raised around the support shaft 11. Now the latch 9
The hook portion 13 automatically engages with the engaging protrusion 15 as shown in FIG. 5 to maintain both speaker units 1, 1 in the expanded state. Next, the upright latch 9
Since the clamping piece 14 protrudes above the center between both speaker units 1, 1, it can be inserted into the sun visor 8 from the front as shown in FIG. It will be crimped and clamped.

The above is the proposed speaker installed in the sun visor 8 inside the car.
This is an overall view of the case where the speaker is latched and supported, but in the present invention, the object on which the speaker is latched and supported is not limited to the sun visor. Therefore, the shape of the latch 9 can be changed in various designs depending on the object 8. For example, in the above embodiment, holes 16 may be provided in the plate 10 and the clamping piece 14 of the hook 9 so that the hook can be hung on a nail on a wall. In this case, plate 1
The holding piece 14 may be omitted by simply providing the hole 16 in the hole 16. Further, the plate 10 of the latching tool 9 may be suction-supported on a metal target wall using a magnet 17 as shown in FIG. 7, or may be suction-supported on a wall using a suction cup 18 as shown in FIG. .

Further, the left and right speaker units 1, 1 may have speaker boxes 3, 3 integrally molded from a plastic material, and both speaker boxes 3, 3 may be connected by a thin integrally molded hinge. When the left and right speaker units 1, 1 are connected by a hinge, the hinge 2 can be made separable so that the two speaker units 1, 1 can be placed far apart depending on the volume. In that case, each speaker unit 1 may be provided with means for latching and supporting it to the object 8.

Furthermore, the left and right speaker units 1, 1 may be maintained in the expanded state at any opening angle. In that case, it would be more convenient if the unfolded state could be maintained at several opening angles. The means for maintaining the left and right speaker units 1, 1 at a predetermined opening angle and the means for latching and supporting both speaker units 1, 1 to the object 8 are replaced by a single latching tool 9 as in the illustrated example. It may also be possible to use separate members.

In addition, in the illustrated example, the left and right speaker units 1, 1 are speaker boxes 3, 3 from which sound is emitted.
Although it is assumed that the front sides of the two are closed together with their front sides overlapping, it is also possible to change the design such that the front sides of the two are closed together with their backs facing each other, depending on the shape of the latching means.

As explained above, in the speaker according to this invention, the left and right speaker units 1, 1 are pivotally supported so that they can be opened and closed, and both speaker units 1, 1 can be placed one on top of the other for storage or carrying when not in use. Because it is made into a compact size, it is convenient to carry along with tape cassettes and the like. In addition, since both speaker units 1, 1 can be maintained in the unfolded state and supported by being latched onto the object 8, the advantage is that the portable speakers can be installed anywhere on the go, making it easy to use. has.
