Abstract

The utility model provides a regulator for angles of a loudspeaker, which comprises a fixed frame and a rotary frame, wherein, the rotary frame is pivoted after a sleeve shaft of the fixed frame and matches a steel bead for clamping different through holes for realizing the regulation of rotary angles of a loudspeaker by using the sleeve shaft as a fulcrum. After the rotary frame is turned upwards, an alt horn and an undertone horn are positioned on a central point of a mediant horn. After the rotary frame is turned downwards, the alt horn and the undertone horn keep a proper distance with a paper basin of the mediant horn. The utility model has the advantages of simple structure, convenient assembly and saved manufacture cost. The utility model avoids the defect that the alt horn and the undertone horn contact the paper basin of the mediant horn to reduce the vibration space of the paper basin caused by the deflection of shift.

Description

A kind of loud speaker angular adjustment apparatus

The utility model relates to a kind of loud speaker angular adjustment apparatus, refer to especially a kind of can be by the simple and easy adjusting device that high and low sound loudspeaker is carried out angular adjustment of pulling.

General boombox, common center at mediant trumpet, be installed with high and low sound loudspeaker side by side, these high and low sound loudspeaker are regulated its angle by a kind of adjusting device, to reach best acoustics, existing adjusting device mainly is after high and low sound loudspeaker are installed to fixed mount, fixed mount to be linked on the axle sleeve with a spheroid, support body reaches the angular adjustment of these high and low sound loudspeaker because of the rotation of spheroid; There is following shortcoming in this device: 1, complex structure during assembly fee, and higher because of the required precision of spheroid and sleeve, has increased the manufacturing cost of material; When 2, these high and low sound loudspeaker playback, can't correctly get back to former central point, influence the sounding effect that sound vanishes.3, because of the deviation of displacement, easily make high and low sound loudspeaker touch the cone of mediant trumpet, the vibrations space of its cone is reduced.

Main purpose of the present utility model is to provide a kind of loud speaker angular adjustment apparatus, it comprises a fixed mount and a rotating turret, after rotating turret is pivotally attached to the sleeve of fixed mount, is fulcrum with this sleeve, cooperate the engaging of steel ball, realize the adjustment of rotational angle different open-works.

Another purpose of the present utility model is by the engaging of steel ball and open-work high and low sound loudspeaker to be adjusted to certain angle by simply pulling, and makes that to adjust operation more quick.

Another purpose of the present utility model is to make high and low sound loudspeaker correctly to playback to central point, and performance is with the best sound effects of source of sound and the vibrations space of reducing the restriction cone.

The purpose of this utility model is achieved in that provides a kind of loud speaker angular adjustment apparatus, it comprises a fixed mount and a rotating turret, this fixed mount has a round bar that is fixed on the mediant trumpet, the lamellar body of a continuous bending is equipped with in the round bar top, the bending segment of lamellar body and top have a grooving box hollow sleeve respectively, and put into spring and steel ball at this grooving; The both sides of this rotating turret have flat board respectively, are used to install high and low sound loudspeaker, and there is the horizontal symmetry wall of dashing forward in its surperficial central authorities, and this prominent wall extends rearward to be two lugs, and vertical horizontal triangular shape slide plate is then arranged at prominent wall bottom, and this slide plate has the open-work of high and low position; After rotating turret is pivotally attached to the sleeve of fixed mount by lug, be fulcrum, cooperate the engaging of steel ball, realize the adjustment of its rotational angle different open-works with this sleeve.In addition, the lamellar body of this fixed mount top is one to extend upward and oblique upwardly extending again bending lamellar body behind the stubborn folding of shape; After upwards pulling this rotating turret, high and low sound loudspeaker are positioned at the central point of mediant trumpet; After rotating this rotating turret, the cone of high and low sound loudspeaker and mediant trumpet keeps certain spacing.

The fixed mount that has steel ball that the utility model provides cooperates the rotating turret be articulated in this fixed mount, makes the high and low sound loudspeaker of boombox just realize the adjustment of angle by simple operations; It is simple in structure, and it is convenient to assemble, the manufacturing cost of having saved material; Avoided deviation, made high and low sound loudspeaker touch the cone of mediant trumpet, made the shortcoming of the vibrations space minimizing of cone because of displacement.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a schematic perspective view of the present utility model.

Fig. 2 is a perspective exploded view of the present utility model.

Fig. 3 is the embodiment schematic diagram that is assembled into mediant trumpet of the present utility model.

Fig. 4 is a part cutaway view of the present utility model.

Fig. 5 is a sectional side view of the present utility model.

Fig. 6 is an operation embodiment schematic diagram of the present utility model.

As shown in Figure 1, 2, the utility model mainly comprises a fixed mount 1 and a rotating turret 2, wherein, this fixed mount 1 has a round bar 11 that is fixed on the mediant trumpet, the lamellar body 12 of a continuous bending is equipped with in round bar 11 tops, and the bending segment of lamellar body 12 has a grooving 13, is used for putting into a spring 14 and a steel ball 15, there is a hollow sleeve 16 on the top of lamellar body 12, is used for articulating rotating turret; The both sides of this rotating turret 2 are respectively equipped with dull and stereotyped 21, be used for fixing high and

low sound loudspeaker

3,4, its central authorities are provided with laterally prominent wall 22, should extend rearward to be two lugs 23 by prominent wall, at lug 23 fixing hole 231 is arranged, vertical horizontal triangular shape slide plate 24 is arranged at the bottom of prominent wall 21, and the open-work 241,242 of high and low positional alignment is arranged on this slide plate 24;

As shown in Figure 3, by above-mentioned combination, this rotating turret makes slide plate 24 withstand steel ball 15 with sleeve 16 pivot joints of fixing hole 231 with fixed mount 1 lamellar body of lug 23, round bar 11 is fixed on the center of mediant trumpet 5, and making rotating turret can be that fulcrum rotates up and down with sleeve 16; And be engaged to the different open-works 241,242 of slide plate 24 by steel ball 15, rotating turret located, and realize the adjustment of these high and

low sound loudspeaker

3,4 angles.

Shown in Fig. 4,5, rotating turret of the present utility model is pivotally attached to the sleeve 16 of lamellar body 12 with lug 23, form a rotating fulcrum, the slide plate 24 of rotating turret 2 bottoms then withstands steel ball 15, makes slide plate 24 when mobile, because of this steel ball 15 is easy to slide, and to the engaging of open-work 241,242, play positioning action, rotating turret is able to the angle of rotational fixation up and down, realizes the adjustment of high and

low sound loudspeaker

3,4 angles.
