Description

Nature source of sound recording/displaying device

The utility model relates to a kind of music recording/displaying device, refers to especially a kind ofly natural source of sound to be stored in the device of playing in the storer.

Industry and commerce is grown up fast, brings the greatest pressure of more people, anxiety and insomnia today that science is prosperous, produces not clear slight illness to cause the people.Music can make people's soul, psychology and health produce to a certain degree the variation of adjusting.People are just outer to imitating after busy a period of time, spend holidays in the countryside, and it is joyful that the sound equipment of Appreciation of Nature will make popular feeling life therebetween.Therefore produced some and relevant naturetone has been embodied in device on the medium such as music belt, CD, listened to for the user.But existing product has following shortcoming:

1, naturetone all has its rule and specific tone, therefore will make a large amount of waste of memory space on including.

2, poor selectivity usually needs to finish at the section source of sound, must searching can select the source of sound desired, and immediate effect is relatively poor.

The purpose of this utility model is to provide a kind of natural source of sound recording/displaying device, it is beneficial to the characteristic that the Nature sound rule repeats, make it and specific source of sound can be stored in the storer in digital mode, and the characteristic of utilizing storer to divide, and can give the proper arrangement storage by the source of sound that several are different, and the mat control processing circuit is to reach the characteristic of instant selection.

Secondary objective of the present utility model is to provide a kind of natural source of sound recording/displaying device, utilizes it to repeat continuable characteristic, source of sound is played out the source of sound of rule, coordination.

The purpose of this utility model is achieved in that a kind of natural source of sound recording/displaying device, comprises front casing, rear casing, and a base and a Sound Processor Unit and a volume are adjusted circuit.Wherein sound treatment circuit connects pulse producer by oscillator, connect control logic circuit again, control logic circuit connects the external key switch, and clock generator connects pulse producer and electronic selector, and the input of electronic selector connects ROM (read-only memory), storer is divided into several memory blocks, it connects the address generator, and the output of electronic selector connects decoder decode, again through wave filter and current buffer, to note amplifier, arrive loudspeaker again; The sequence switch output that volume is adjusted circuit connects note amplifier, and its input connects control logic circuit, and front casing is provided with corresponding key hole and volume knob hole.

It is two circuit boards that set up separately that sound treatment circuit and volume are adjusted circuit, and it is located at a front casing, rear casing and base and forms in the space.

The utility model can be stored in the sound of the Nature in the ROM (read-only memory), and by the memory block that can divide to store several different naturetone persons.By repeating and continuous signal output, the melodious source of sound of nature is constantly gushed out, and the soul that can console the hearer, use diastole, relax tightly collapse, unhappy mood.

Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
