Abstract

A MP3 player using solar energy. The present invention provides a MP3 player using solar energy, it make users, especially the travelers, easy to obtain energy for making the player run, to solve the problem that rapid consuming of general batteries, and the batteries can not be long time used, while using fixed power source limits the position of a person. The playback device comprising a solar panel (1), a direct current converter (2), a rechargeable battery (3), a central central control chip (4), a digital memory (5), a MP3 decoder (6), a D/A converter (7), keys (8) and a digital interface (9). The solar panel (1) receives the solar light, and converted it into electronic energy. After been converted in the direct current converter (2), the energy is supplied to the MP3 player. The central central control chip (4) is working according to the energy output from the direct current converter (2), so make the whole MP3 player work. According to the present invention, it can not limit a person in position and power source because of using solar energy as its power source, it is convenient and also benefit to environment.

Description

Solar MP3 Player Technical Field

The invention relates to an MP3 player, in particular to a solar MP3 player using green environmental protection energy. Background technique

The existing MP3 players in the technical solution are all focused on data transmission, voice processing, and multiple uses for updating, without considering the issue of energy; the existing ordinary MP3 players mainly use carbon Or alkaline batteries to provide energy, or directly use ordinary power sources to provide energy, but the way these energy are provided limits the use of MP3 players by users. The battery has a limited storage capacity, and soon the battery will be used up. Light must be updated from time to time. As we all know, carbon or alkaline batteries are cheaper but cause irreparable damage to the environment. The direct use of ordinary power requires users to use MP3 players in a fixed place and cannot move at will. Even if a rechargeable battery is used, it must be charged on a fixed power source, causing inconvenience in use. Summary of the Invention

In order to overcome the shortcomings of the prior art, the present invention aims to provide an MP3 playback device that allows users, especially travelers, to easily obtain energy. The use of green environmental protection energy-a solar energy as the energy of MP3 players, can protect the environment and save resources.

Another object of the present invention is to use rechargeable solar cells or rechargeable batteries at the same time. The useful life of a solar cell is more than ten years, and the useful life of a rechargeable battery is more than two years. The electrical energy that can be converted is stored and can be released when using an MP3 player, so that it can be used under sufficient and inadequate light energy, which is not only convenient for users, but also has an environmental protection effect that ordinary MP3s cannot do. To.

To achieve the above object, the solar MP3 player of the present invention includes: a solar photovoltaic panel, a rechargeable battery, a DC converter, a central control chip, a data storage, an MP3 decoder, and a digital / Analog converter, buttons and data interface. The solar photovoltaic panel can receive light energy and convert it into electrical energy; the central control chip works according to the electrical energy converted by solar light energy, and drives the operation of the entire MP3 player.

The DC converter is connected to a solar photovoltaic panel, and can convert the light energy received by the solar photovoltaic panel into electrical energy and output it to a central control chip to provide electrical energy for the MP3 player to perform work. The battery is connected, and the light energy received by the solar photovoltaic panel can be converted into electric energy and input into a rechargeable battery, stored, and released when the MP3 player is needed.

After adopting the present invention, since a green environmental protection energy source, a solar energy, is used as its energy source, it is not limited by energy when used, which is convenient and environmentally friendly.

Since a rechargeable battery is used in the present invention, the solar-converted electric energy can be stored, and the user can use the MP3 player anytime, anywhere, which greatly facilitates users, especially travelers.

The purpose, features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic diagram of energy conversion of the present invention;

FIG. 2 is a working principle diagram of the present invention;

FIG. 3 is an electrical schematic diagram of the central control chip according to the present invention. detailed description

As shown in FIG. 1, the solar MP3 player according to the present invention includes a solar photovoltaic panel 1, a DC converter 2, a rechargeable battery 3, a central control chip 4, a data memory 5, an MP3 decoder 6, and a digital / analog converter. 7. Button 8 and data interface 9; the solar photovoltaic panel 1 can receive light energy and convert it into electrical energy, and convert the output through DC converter 2 to provide power for the MP3 player; the central control chip 4 according to the DC converter 2 The output power is converted to work and drive the operation of the entire MP3 player.

The DC converter 2 is connected to the solar photovoltaic panel 1 and receives the solar photovoltaic panel 1 The light energy is converted into electrical energy and output to the central control chip 4, which drives the operation of the entire MP3 player. The DC converter 2 is also connected to the rechargeable battery 3 at the same time, and converts the light energy received by the solar photovoltaic panel 1 into electric energy and inputs it into the rechargeable battery 3 for storage. When the solar energy is insufficient, an MP3 player is needed Release it from time to time.

Referring to FIG. 1 and FIG. 3, the central control chip 4 can monitor power of unstable solar energy, monitor the output energy of the sunlight, and control the DC converter 2 through software stored in the central control chip to stabilize the power supply. Output within a certain range.

Referring to FIG. 2 and FIG. 3, the present invention uses electric energy converted by receiving solar energy as the power source of the entire MP3 player, and when in use, the power source can be directly used to drive the entire machine.

Obviously, the above-mentioned solar photovoltaic panel 1 does not have to be installed in the MP3 player, and can also be designed as an independent device, and when needed, it is connected with the MP3 player to provide power for the MP3 player. The invention has the advantages of simple structure, convenient use, environmental protection and energy saving. In the present invention, a green clean energy source, solar energy, is selected as the energy source, and the solar energy can be converted into electrical energy for storage, and it will not be limited by time and place when used. In terms of cost, on the surface, the cost of ordinary carbon or alkaline batteries is cheaper than solar cells, but from the cost accounting and long-term benefits after long-term use, its cost is far lower than that of ordinary MP3 players, and The benefits are much higher than ordinary MP3.
