Abstract

The utility model relates to a broadcasting device which is controlled through limb action, wherein a sense switch is arranged on the broadcasting device, and the sense switch is shielded through a non-contact mode to achieve that the functions of turning on, turning, muting or adjusting volumes are selected.

Description

Public address system with limb action control

Technical field

The utility model relates to a kind of public address system with limb action control, refers to especially a kind ofly can cover inductive switch by limb action and control unlatching, close the public address system with volume.

Background technology

Music is one of the method for pressure of releiving, people usually loosen the mood and a mood of relaxing by listoning music, music also is one of instrument of environment construction atmosphere, no matter and sound equipment, computing machine, radio or MP3 device, all must reach by public address system (loudspeaker), except itself is built-in, general employed public address system mostly is circumscribed greatly, can increase or reduce quantity according to demand, as Fig. 1 and shown in Figure 2, the general normal circumscribed public address system 1 that uses, it is by set switch 11 on this public address system 1, adjust volume, open sound and close sound, and more common switch 11 also has push type and allots formula or the like pass and open except knob, but the switch of this type of contact is often under long-time the use, the problem that loose contact can occur or come off and damage, and the switch of contact mostly susceptibility is lower, and can't correctly adjust required demand volume.

Summary of the invention

Fundamental purpose of the present utility model is to overcome the deficiencies in the prior art and defective, a kind of public address system with limb action control is proposed, this public address system is provided with inductive switch, make public address system cover this inductive switch in the different time difference by hand or other foreign object, reach select to open, close, function such as quiet and adjustment volume.

Secondary objective of the present utility model is, because set inductive switch is a non-contact switch on this public address system, therefore can reduce traditional touch switch and cause wearing and tearing mistake problem,, more can increase the temperament and interest of use so that reach the purpose that improves serviceable life in following of long-term use.

For reaching above-mentioned purpose, the utility model provides a kind of public address system with limb action control, it is mainly public address system and is provided with an above switch, for the control public address system, it is characterized in that, the set switch of this public address system is contactless inductive switch, control thus public address system unlatching, close, conversion such as quiet and volume.

The utlity model has following useful technique effect:

1, the utility model makes public address system cover this inductive switch in the different time difference by hand or other foreign object because this public address system is provided with inductive switch, reach select to open, close, function such as quiet and adjustment volume.

2, the utility model is owing to set inductive switch on this public address system is a non-contact switch, therefore can reduce traditional touch switch and cause wearing and tearing mistake problem in following of long-term use, so that reach the purpose that improves serviceable life, more can increase the temperament and interest of use.

Embodiment

For reaching above-mentioned purpose and effect, technological means that the utility model adopted and structure illustrate in detail that with regard to preferred embodiment of the present utility model its feature and function are as follows, in conjunction with the accompanying drawings in order to understanding fully.

See also shown in Figure 3, be stereo appearance figure of the present utility model, find out by knowing among the figure, it mainly respectively is provided with inductive switch 21 on public address system 2, this inductive switch 21 can be any of non-contact switch such as Photoinduction device, heat induction device, infrared induction device or temperature sensing device, the major function of this inductive switch 21, be to detect covering of limbs or object, and utilize mistiming that different inductive switches 21 cover or the mode of covering frequency to reach that control public address system 2 is opened, closed, the function of quiet and adjustment volume.In the utility model, can be respectively arranged with one, two and three inductive switches 21, below detailed explanation will be arranged at public address system 2.

See also Fig. 4, Fig. 5 and shown in Figure 6, be preferred embodiment of the present utility model, find out by knowing among the figure, public address system 2 is provided with two inductive switches 21, move from right to left or from left to right and by these two inductive switches 21 with hand or foreign object, at this moment, two inductive switches 21 are poor by the different time of successively being responded to, in order to adjust the sound size that public address system 2 is exported, if cover two inductive switches 21 simultaneously with hand or foreign object simultaneously, then can make public address system 2 reach quiet purpose.For example move and cover these two inductive switches 21 in regular turn and can be set at amplification of volume with right-to-left, otherwise then for lowering the volume.The utility model can be reached control public address system 2 by electronic components such as for example comparer, differential amplifier, the Audio Controller that is connected inductive switch 21 or the program-controlled devices of arranging in pairs or groups.

See also shown in Figure 7, be further embodiment of the present utility model, find out by knowing among the figure, this public address system 2 is except that original two inductive switches 21, one inductive switch 21 is set in the top in addition, and can reach unlatching in regular turn, close or play the purpose of next song this moment by the inductive switch 21 that repeats to cover this top.

See also shown in Figure 8ly, be further embodiment of the present utility model, find out, when this public address system 2 only is provided with an inductive switch 21, then can reach unlatching in regular turn, close or quiet purpose by repeating to cover this inductive switch 21 by knowing among the figure.

See also Fig. 9 and shown in Figure 10, be further embodiment of the present utility model, find out by knowing among the figure, this public address system 2 can be arranged at stereo set 4, audio-visual equipment 5 or other multimedia equipment in addition, by inductive switch set on the public address system 2 21 reach unlatchings, close, the size of quiet and adjustment output sound.

The inductive switch 21 that above-mentioned public address system 2 is set, be relevant contactless devices such as Photoinduction device, heat induction device, infrared induction device or temperature sensing device, owing to do not need via directly touching, therefore under using for a long time, can reduce as conventional knob formula, push type and allot touch switch wear problems such as formula, and can improve serviceable life greatly.
