Description

[Detailed Description of the Invention] This invention relates to a small electronic device with a stand, such as a microcassette tape recorder, a portable radio, and a speaker.

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

This invention was devised in view of the above points, and its purpose is to provide a small electronic device with a stand that can effectively use the stand and expand the range of use of the small electronic device.

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

An example in which this invention is applied to a small speaker with a stand will be described. As shown in FIGS. 1 and 2, the small speaker with stand 10 includes a rectangular housing 12 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. The main body 16 is
It has a rectangular back wall 17 as a wall portion, and this back wall includes an upper end edge 17a as one end edge and a lower end edge 17b opposite thereto. Further, the stand 14 is attached to the main body 16 so as to be rotatable around a rotation center axis, which will be described later.
The main body 22 has a substantially rectangular flat body 22 located opposite the back wall 17 of the housing 2, and a pair of extension parts 24 extending perpendicularly from the body and facing the side surfaces of the housing. The main body 22 of the stand 14 includes the housing 12
The first
It has an end edge 22a, and a second end edge 22b spaced apart from and facing the first end edge. Further, the main body 22 has a curved portion 29 bent toward the housing 12 at the second end portion 22b. Furthermore,
The main body 22 has an engagement groove 2 formed approximately in the center thereof.
7, and a suction cup 29 is removably fitted into this engagement groove.

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. The central axes of these support shafts 32 act as movable central axes of the stand 14. Each support shaft 32 is connected to the stand 14
The support groove 30 of the housing 12 is inserted into the through hole 34 formed in the extending portion 24 of the housing 12.
is rotatably supported within. Therefore, the stand 14 is rotatably supported by the housing 12 by the support shaft 32. In this case, the upper edge 17a of the housing 12 and the first
The end edge portion 22a is located near and parallel to the rotation center axis. The distance between the upper edge portion 17a and the rotation center axis is smaller than the distance between the first edge portion 22a and the rotation center axis.

As can be clearly seen from FIG. 5, each support shaft 32 includes a cylindrical large diameter portion 36 having a diameter and axial length approximately equal to the diameter and axial length of the through hole 34, and a cylindrical small diameter 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 part 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.

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 wall of the housing 12, the lower edge of the housing 12 and the second edge of the stand 14 are placed on the floor. The speaker 10 can be placed at an angle with respect to the floor while in contact with the speaker. The stand 14 presses the extensions 24 in the direction toward each other to release the engagement between the spline 44 and the protrusion 46, thereby supporting the support shaft 3.
It can be rotated freely relative to 2. Then, with the extension portion 24 pressed, the stand 14
After rotating the spline 44 and the protrusion 46 by a desired angle, the pressing force applied to the extension part is removed.
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 tilted state of the speaker 10 can be freely changed.

Further, as shown in FIG. 7, by removing the suction cup 29 from the stand while the stand 14 is rotated, the speaker 10 can be installed with the stand placed on the floor.
In this case, as described above, the first
Since the distance between the edge 22a of the housing 12 and the rotational center axis is set larger than the distance between the upper edge 17 of the housing 12 and the rotational center axis, it is difficult to rotate the stand 14 to any rotational position. Even when the housing 12 is moved, the upper edge 17a of the housing 12 does not protrude from the main body 22 of the stand 14. Therefore, in any rotational position, the stand 1
The speaker can be stably installed with the entire surface of the main body 22 of No. 4 in contact with the floor surface.

In addition, as shown in FIG. 6, by fitting the suction cup 29 into the engagement groove 27 of the main body 22 of the stand 14, the speaker 10 can be attached to an attached part, for example, a windshield of an automobile, as shown in FIG. It can be removably attached to. 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.

Furthermore, as shown in FIG. 9, the speaker 10 can be used by being attached to, for example, a bicycle handlebar. 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 moves the support shaft 32 and the stand 14 in a direction opposite to the direction of rotation thereof, that is, the stand moves toward the housing 1.
It is biased in the direction of approaching 2. 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 25 bent toward the housing, the speaker 10
It is reliably prevented from coming off from the handle.

As described in detail above, the small electronic device with a stand of this invention includes a housing having a substantially flat wall having one end edge and the opposite end edge, and the housing being rotatable. a substantially flat stand supported by and located opposite the wall;
The stand has a rotation center axis located near the one end edge of the housing and extending substantially parallel to the one end edge, and a rotation center axis located near the one end edge of the housing and extending substantially parallel to the one end edge. a first edge extending substantially in parallel; and a second edge separated from and facing the first edge, the distance between the first edge and the rotation center axis being , is formed to be larger than the distance between the one end edge of the housing and the rotation center axis. Therefore, the small electronic device with a stand of this invention can effectively utilize the stand, and the range of use of the small electronic device with a stand can be expanded.

Note that the above-mentioned embodiments are for illustrating this invention and are not intended to limit this invention to any extent. For example, the present invention is not limited to small speakers, but can also be applied to other small electronic devices, such as portable radios, small cassette tape recorders, microphones, etc. Furthermore, it goes without saying that the shape and size of the stand can be changed as necessary. Further, the support shaft may be composed of a single continuous support shaft, or the support shaft may be non-rotatably attached to the housing. Furthermore, the engaging portion to which the suction cup is attached is not limited to a groove, but may also be a hole to obtain the same effect. Further, the configuration of the holding mechanism is not limited to the combination of splines and protrusions, and can be changed as necessary.
