Abstract

The utility model relates to a valley-echo electronic analog device which is characterized in that the outer package is a plastic casing, a pickup transmitter, a turn knob which adjusts the size of volume and a turn knob which adjusts delay time are arranged on a panel, a reproducing loudspeaker is arranged on the feeder line end of the casing, a block of electronic circuit board is arranged in the casing, and a power supply circuit, a preamplification circuit, a time delay circuit and an audio power amplification circuit are arranged on the electronic circuit board. After a power supply is switched on, when people send out sound, echo which is delayed by the device can be clearly heard from the far, and people feel like staying in the valley. The device has simple assembly and low cost, and can be used in various park scenic spots and tour stations.

Description

Mountain valley echo electronic simulation

This device belongs to tourist recreation facility field, particularly a kind of to the mountain valley echo simulate, the enhanced electron device.

In today that people's culture life improves day by day, festivals or holidays, taking the companion two-day weekend goes to travel in the Nature of countryside, or go to the park, go sightseeing in the sight spot, become the thing that majority would like to do, but static environment always makes the people feel lively not enough, vivaciously, the teenager is unwilling to remain out of the limelight, and total hope is when going sightseeing, can produce dynamic atmosphere and color, call out one such as loud, transmitted sympathetic response immediately at a distance, the echo of oneself is heard on wash rice ground clearly, or in the woods that the liquid look shrouds, shout, echo is shaken and is shaken sky at a distance, breaks quiet night, just as body faces the fairyland, excitement is arranged, some parks, sight spot, in the area that makes the artificial hillock group, load onto the people and be mountain valley echo analogue means, the echo that makes the location that does not show echo originally all rely on the electronic installation in plant somewhere to remove to produce clear wash rice, this will increase the entertainment effect of these tourist attractions, allow interesting teenager remove to appreciate own moving yaup, to find pleasure in it.

The purpose of this utility model be exactly in tourist attractions or the Yezhong, ore deposit increase its dynamic atmosphere, produce a kind of echo effect of clear wash rice, add a little abundant enjoyment to people's life.

The utility model relies on following technical proposals to realize:

A kind of mountain valley echo electronic simulation, it is characterized in that, external packing is a plastic casing, a pickup transmitter, one are housed on the panel regulate the turn-knob of volume U, and the knob T of a control lag time, the housing sidepiece has power lead and the power output feeder of introducing civil power, the feeder line end is connected to playback loudspeaker, an electronic circuit board is housed in the housing, be furnished with the power circuit part of transformation rectification on the plate, with the pre-amplification circuit part of signal amplification, with the delay circuit part of signal lag, reach the audio power amplifying circuit part.

After the voice signal that pickup transmitter sends the people is delivered to pre-amplification circuit, amplifying signal enters in the delay circuit that is made of the delay circuit chip, the time that needs interest for delinquency, can be controlled within the specific limits by regulating T, signal through time-delay is delivered in the audio power amplifying circuit, need the output volume size, can adjust volume within the specific limits by the numerical value of regulator potentiometer U.

This device can hang over treetop, fixed buildings or be placed on the shelter respectively in the environment of travelling, and hanging loudspeaker is in distance visitor shelter far away.After connecting with the mains,, just can hear a kind of echo like the mountain valley echo when people shout a shout, size according to the place, empty ore deposit degree is transferred T and the big or small U of echo volume time delay, makes the people feel excitement on the spot in person, and the sound of oneself the happy impression of echoing between universe.

Further specify embodiment below in conjunction with accompanying drawing:

Description of drawings:

Fig. 1 is a mountain valley echo electronic simulation schematic appearance;

Fig. 2 is a power circuit diagram on this device circuit board;

Fig. 3 is this device circuit board wiring diagram.

Among the figure, device external packing housing 1, it is a box body by the plastics compacting, civil power is linked on the box body by feeder line 3, the electronic circuit board of installing in the box body 2 is furnished with power circuit part 2.1 respectively, providing U1 with alternating current after the transformation rectification is 5V and U2, U3 is three groups of direct supplys of 12V for ± 25V and U4, pre-amplification circuit 2.2 is finished by the UPC4558 chip, be connected to delay circuit part 2.3 through amplifying signal, delay circuit is made of delay chip M50195P, can carry out the control lag time by Multi-band switch 8, electric signal through time-delay is connected to audio power amplifying circuit 2.4, it mainly amplifies signal by LM1875, and the magnitude of amplification can be regulated by 10K potentiometer 7, and signal is connected to playback loudspeaker 5 output sounds by feeder line 4 again, signal power can make echo reverberate on the earth of empty ore deposit up to 30W.

The assembling of this device is simple, cheap, can use for each sight spot, park, tourism guard station.
