Description

[Detailed Description of the Invention] This invention relates to a set of small speakers with stands.

2. Description of the Related Art As a small electronic device with a stand, for example, a speaker having a stand attached to its back surface is known. This stand is rotatably mounted and can be set in a position in close contact with the rear surface of the speaker or in a position inclined at a predetermined angle with respect to the rear surface. By setting the stand in the inclined position, the speaker can be placed on the floor in an inclined position. However, in the past, this stand could only be used to install the speaker in the above-mentioned inclined position, and could not be said to be used effectively.

This invention was made in view of the above points, and its purpose is to provide a set of small speakers with stands that can make effective use of the stands and expand the range of use of the small speakers.

Embodiments of this invention will be described in detail below with reference to the drawings.

Since the pair of small speakers with stands according to this invention have the same structure, one of the small speakers will be described in detail below as a representative.

As shown in FIGS. 1 and 2, the small speaker with stand 10 has a rectangular housing 1.
2 and a stand 14 attached to the housing. The housing 12 has a main body 16 and a baffle plate 20 that is removably attached to the main body and supports the speaker unit 18. Further, the stand 14 is rotatably attached to the main body 16, and has a substantially rectangular flat main body 2 located opposite to the back side of the housing 12.
2 and a pair of extension parts 24 extending perpendicularly from the main body and facing the side surfaces of the housing. Further, the stand 14 has four connecting parts 23 provided on the main body 22. Each connecting portion 23 has a rectangular insertion hole 25 as an insertion notch formed through the main body 22 and a connecting claw 27 having an L-shaped cross section. The connecting claw 27 extends vertically from the main body 22 in a direction away from the housing 12 and extends parallel to the main body 22 above the insertion hole 25 . Furthermore, the main body 22 has a curved portion 29 bent toward the housing 12 at its lower end.

As shown in FIGS. 3 to 5, the housing 12 has a pair of support grooves 30 formed in opposing side plates 26 and 28, respectively. The support grooves 30 are located opposite to each other. Also,
The speaker 10 includes a pair of support shafts 32 that rotatably support the stand 14. Each support shaft 32
is inserted into the through hole 34 formed in the extension part 24 of the stand 14, and the housing 1
It is rotatably supported within the support groove 30 of No. 2.
Further, as can be clearly seen from FIG. 5, each support shaft 32 has a cylindrical large diameter portion 36 having a diameter and axial length substantially equal to the diameter and axial length of the through hole 34, and a cylindrical small diameter portion 36. portion 38 and a fixing portion 40 having a semicircular cross section. The large diameter portion 36 is rotatably inserted into the through hole 34, and the small diameter portion 38 is rotatably supported by the support groove 30. The fixing portion 40 protrudes into the housing 12, and the flat portion of the fixing portion is located approximately parallel to the bottom surface of the housing. Furthermore,
A screw hole 42 is formed in the fixing portion 40 . Further, a spline 44 is formed on the peripheral edge of the large diameter portion 36 on the small diameter portion 38 side, and a through hole 34
A large number of protrusions 46 that can be engaged with the splines 44 are formed on the peripheral edge of the housing. Then, by inserting the support shaft 32 into the through hole 34, the spline 44 and the projection 46 are engaged with each other. Therefore, the rotation of the stand 14 with respect to the support shaft 32 is normally restricted by the spline 44 and the protrusion 46. However, by elastically deforming the extending portion 24 in the direction of the arrow in FIG. 14
rotation is possible. In this way, spline 4
4 and the protrusion 46 constitute a holding mechanism that restricts rotation of the stand 14.

Further, as shown in FIGS. 3 and 4, the small speaker with stand 10 has a boss portion 4 of the main body 16.
An elastic member, for example a leaf spring 50, screwed to the
It is equipped with This leaf spring 50 is connected to the housing 1
2, and both ends thereof are screwed to the fixing portions 40 of the support shaft 32, respectively. The leaf spring 50 is elastically deformed in response to the rotation of the support shafts 32, and biases each support shaft in the opposite direction to the rotation direction of the support shafts.

In addition, in FIGS. 1 and 2, the reference numeral 52
connects the speaker 10 to a tape recorder (not shown)
This shows a connection cord for electrically connecting to, etc. Further, in FIG. 4, reference numeral 54 indicates a protruding portion extending perpendicularly from the buttful plate 20. As shown in FIG. When the buttful plate is attached to the main body 16, the protrusion 54 is inserted into the support groove 30, and the protrusion 54 is inserted into the support shaft 3.
2. Prevents misalignment.

Further, the other small speaker also has the same shape and structure as the one small speaker 10 described above.

An example of how the small speaker with stand 10 configured as described above is used will be described.

First, as shown in FIG. 6, by rotating the stand 14 at a desired angle with respect to the back surface of the housing 12, the speaker 10 can be placed in an inclined state with respect to the floor surface. Stand 14
can be freely rotated with respect to the support shaft 32 by pressing the extensions 24 in a direction toward each other and releasing the engagement between the spline 44 and the protrusion 46. Then, after rotating the stand 14 to a desired angle while pressing the extension part 24,
By removing the pushing force applied to the extension, the spline 44 and projection 46 are re-engaged, and the stand is held in the desired rotational position. In this way, the stand 14 can be freely set to a desired rotational position relative to the housing 12, and the speaker 10
The inclination state of the can be changed freely.

In addition, as shown in FIG. 7, a set of speakers 1
0 can be removably connected to each other. This connection is made as follows. As shown in FIGS. 7 to 9, first a set of speakers 1
0 facing each other in opposite directions, and insert the connecting claw 27 of each stand 14 into the insertion hole 25 of the other stand.
Insert the stands into each other and make the stands stick together. Then, by sliding one of the speakers 10 and meshing the connecting claws 27 with each other, the respective speakers are connected to each other. If the respective speakers are to be separated from each other, the above operation is reversed. In this way, these speakers 10 can be connected to each other in a compact state when carried, and can be separated from each other when in use. On the other hand, as a conventional small speaker, one in which a pair of speakers are rotatably connected to each other is known. In this speaker, when carried or not in use, each speaker is rotated to face each other, and when in use, each speaker is rotated in a direction away from each other.
However, since the speakers are inseparably connected to each other, there is a drawback in that it is not possible to provide sufficient spacing between the speakers during use. On the other hand, the speaker 10 can be easily separated from the other speaker 10, and the interval between each speaker can be freely set. Also, since a pair of speakers have the same shape and structure, one type of speaker can be used for two
They can be easily and inexpensively manufactured.

Furthermore, the speaker 10, as shown in FIG.
For example, it can be used by being attached to the handlebar of a bicycle. For example, when the stand 14 is rotated in the direction away from the housing 12 from the state shown in FIG. be done. As a result, the leaf spring 50 is elastically deformed and biases the support shaft 32 and the stand 14 in a direction opposite to the direction of rotation thereof, that is, in a direction in which the stand approaches the housing 12. Then, in this state, by inserting the bicycle handlebar between the stand 14 and the housing 12, the handlebar is sandwiched between the stand and the housing. Thereby, the speaker 10 is fixed to the handle. Note that since the stand 14 has a curved portion 29 bent toward the housing, the speaker 10 is reliably prevented from coming off the handle.

Further, as shown in FIG. 6, by forming an engagement groove 56 in the main body 22 of the stand 14 and fitting a suction cup 58 into this engagement groove, the speaker 10 can be used, for example, in an automobile, as shown in FIG. Can be installed on the windshield. And speaker 1
It is also possible to adjust the rotational position of the housing 12 while the housing 12 is attached to the windshield.

As described in detail above, the set of small speakers with stands of this invention includes a housing, which is rotatably supported with respect to the housing, and which is disposed outside the housing and facing the housing. , and a substantially flat stand having a connecting portion, the connecting portion of one of the small speakers has a connecting claw of a predetermined shape and an insertion notch of a predetermined shape, and The small speaker is equipped with a connecting claw and an insertion notch having the same shape as the connecting claw and insertion notch of one of the above-mentioned small speakers, and the connecting claw of one small speaker can be inserted into the insertion notch of the other small speaker. The connecting portions of both the small speakers are configured to be removably connectable to each other. Therefore, according to the small speaker with a stand of this invention, the small speaker can be placed on the floor in an inclined state, for example, and the small speakers can be removably connected to each other. Therefore, the stand can be used effectively, and the range of use of the small speaker with the stand can be expanded.

Note that the above-mentioned embodiments are for explaining this invention and are not intended to limit this invention in any way. For example, it goes without saying that the shape and size of the stand can be changed as necessary.
