Abstract

The utility model relates to a radio sound box equipment, particularly a stereo speaker box matched with a miniature radio-receiver recorder. Sound boxes and a supporting seat are movably hinged and formed into a whole body through a telescopic draw rod. The utility model which can be folded, is easy to carry, fits for home, tour and study, has the advantages of high integrity, convenient usage and placement, beautiful appearance. A miniature active amplifier, digital types and other ornaments can be arranged on the supporting seat according to needs, which ensures a better use effect, multifunction and decorative value.

Description

Portable foldable miniature stereo speaker box

The utility model relates to a kind of radio audio amplifier equipment, particularly with the matching used miniature stereo speaker of miniature radio-cassette player.

Along with the raising of people's living standard and the fast development of electronic technology, this class stereo set of radio-cassette player has moved towards the individual from family to the microminiaturization development, uses object to become single, and purposes is more specific, is widely used in travelling and language learning at home.Time spent is also to high gear time development, such as being equipped with miniature loudspeaker box.What difference is the structure of miniature stereo speaker and traditional separate type audio amplifier be provided with, promptly by two independently miniature loudspeaker box and system horn wire, plug form, carry and use equal inconvenience like this.

The purpose of this utility model designs a kind of collapsible all-in-one micro stereo speaker at above-mentioned situation exactly, has conveniently, is suitable for, characteristics attractive in appearance.

Solution of the present utility model is: be movably hinged in aggregatesly between the audio amplifier by scalable pull bar and bearing, its detailed content is described below referring to accompanying drawing:

Referring to Fig. 1, the miniature stereo speaker of portable and collapsible of the present utility model, it is characterized in that being movably hinged in aggregates by extension type pull bar (3) and bearing (1) between the audio amplifier (2), as Fig. 2, shown in 3, like this, by flexible extension type pull bar (3), it is the spacing of two audio amplifiers of scalable (2), by extension type pull bar (3) is rotated around the pin joint with bearing (1), it is the direction of scalable two audio amplifiers (2), make audibility reach optimum state, the junction of the audio amplifier (2) that characteristics of the present utility model are connected with extension type pull bar (3) in addition is a vacancy (4).When folding this audio amplifier, get final product and shrink again after Telescopic handle (3) closes up 90 ° of audio amplifier (2) rotations, the two ends of bearing (1) just can be collected in the vacancy (4) of two audio amplifiers (2), make the audio amplifier volume after folding reach minimum.The cross section of extension type pull bar of the present utility model (3) is apart from shape, makes like this between each bar of extension type pull bar (3) can not relatively rotate, thereby influences the stability of audio amplifier (2).

The miniature stereo speaker of the portable and collapsible that the utility model provides becomes traditional separate type audio amplifier into integral structure, and can regulate distance and direction between two audio amplifiers as required easily, not only globality is strong, use, place very convenient, have attractive in appearance, the characteristics that are suitable for, and can shrink, folding, be convenient to carry, be suitable for the usefulness of travelling at home and language learning, simultaneously, also can on bearing, adorn miniature activated amplifier, to solve the problem of miniature radio-cassette player power output deficiency, on bearing, also can adorn digital clock or other ornament, make the utility model result of use better, but also can have multi-functional and ornamental.

With figure expression specific embodiments of the present utility model.

At first accompanying drawing is described:

Fig. 1 represents structure chart of the present utility model;

Fig. 2 represents extension type pull bar and the hinged structure chart of bearing;

The profile of Fig. 3 presentation graphs 2;

Fig. 4 represents that the utility model is installed in the schematic diagram on the wall.

According to embodiment shown in the drawings, in the groove at bearing (1) two ends, one end of extension type pull bar (3) is inserted in the U type connection gusset (5) and by bolt (6) and bearing (1) and is movably hinged, the other end at extension type pull bar (3) is connected with miniature loudspeaker box (2), the junction of miniature loudspeaker box (2) is a vacancy (4), this vacancy (4) can make bearing (1) put into, the cross section of each bar of extension type pull bar (3) is a rectangle, when using, audio amplifier of the present utility model both can put on the table, also can be installed on the wall, in the time of on being installed in wall, on wall, fix earlier a metal frame groove (7) as shown in Figure 4, bearing (1) is got final product in notch is shifted frame groove (7) onto.When carrying, can this audio amplifier is folding, promptly will close up behind two audio amplifiers (2) and extension type pull bar (3) half-twist earlier, scalable pull bar (3) is shunk push in the bearing (1), this audio amplifier volume is contracted to minimum.

Claims

1, the miniature stereo speaker of a kind of portable and collapsible, feature of the present utility model are to be movably hinged in aggregates by extension type pull bar (3) and bearing (1) between the audio amplifier (2).

2, the miniature stereo speaker of portable and collapsible according to claim 1 is characterized in that the junction of the audio amplifier (2) that is connected with scalable pull bar (3) is a vacancy (4).

3, the miniature stereo speaker of portable and collapsible according to claim 1 and 2, the cross section that it is characterized in that scalable pull bar (3) is a rectangle.
