Abstract
The utility model discloses a portable audio signal display, comprising an audio signal display circuit which is composed of an audio signal input circuit, an audio signal output circuit, a control circuit, a display circuit and a direct current supply. The audio signal display circuit is arranged in the portable shell. An input and an output jacks arranged on the wall of the portable shell are respectively connected with the audio signal input and the output circuits. The luminous elements of the display circuit are positioned in the via hole which is positioned on the wall of the portable shell. The utility model has the advantages that the audio signal display circuit is arranged in the portable shell with a good appearance. If inserting the output plug of the minimum sound equipment, such as a walkman into the input jack of the utility model and the earphone plug into the output jack of the utility model, the user can enjoy the colorful shining lights sent out by the light emitting diode of the utility model while listening to music.
Description
Technical field:
The utility model relates to a kind of audio level display device, relates to a kind of portable audio Signal Monitor specifically.
Background technology:
The sound signal display circuit is widely used on large-scale radio cassette player, the stereo set, shows by the variation of luminous electric elements with audio signal level, to improve people's appreciation effect, plays the purpose of beautifying the environment.And for some small-sized stereo set such as walkman, radio etc., how not have above-mentioned sound signal to show, make these small-sized audio and video equipments lack sight and interest in use.
The utility model content:
The purpose of the utility model is to provide a kind of can being connected with small-sized audio and video equipment with the portable audio Signal Monitor that shows that audio signal level changes.
For achieving the above object, the utility model can be achieved through the following technical solutions:
The utility model comprises the sound signal display circuit of being made up of sound signal input circuit, audio signal output circuit, control circuit, display circuit, direct supply, and described sound signal display circuit places in the portable housing; On described portable housing wall, offer the input, the output plughole that are electrically connected with described sound signal input, output circuit; Light-emitting component in the described display circuit places in the through hole that is opened on the portable housing wall.
Described control circuit is made of integrated circuit TA7666, also can adopt the sound signal control circuit of other model certainly; Described display circuit is five groups of display units that are in series and formed by light emitting diode, resistance; The anode of the light emitting diode in every group of display unit is electrically connected with described dc power anode, and the other end of the resistance that is in series with described light emitting diode is electrically connected with 10,11,12,13,14 pin of integrated circuit TA7666 respectively.
Advantage of the present utility model is that the sound signal display circuit that will be made up of sound signal input circuit, audio signal output circuit, control circuit, display circuit, direct supply places in the portable housing of a good looking appearance.During use, the output plug of small-sized stereo set such as walkman is inserted in the input jack of the present utility model, headset plug is inserted in the output plughole of the present utility model, can when listening to music, appreciate the glory of the flicker of sending by light emitting diode.
