Abstract

A musical charger, consisting of a charger whose internal circuit is attached a musical circuit controlled by the discharging control circuit. The musical circuit is linked to a buzzer so that music or songs can be played during or after charging to remind and guide, thereby achieving practicability and fun.

Description

The music charger

Technical field

The utility model refers to a kind of charger in charging process or behind full charging especially relevant for a kind of charger, can pass through music or the song music charger as prompting, caution and reception and registration effect.

Technical background

Use charger, battery charge seat on the traveling charger of general traditional type, the car ... Deng charger, the function of mostly having only charging, and in whole charging process, tranquil dullness also can't provide taste in life, because the charger of traditional type itself is other additional functions not, can allow and use the charger person to point out or inform the user rapidly to being recharged under the state that product reached full charging when reception, thereby have much room for improvement.

In view of this utility model people accumulates and is engaged in the industry experience for many years, studies intensively and test improvement repeatedly, nowadays creates a kind of novel music charger finally, can forgo and commonly use the product shortcoming, to promote effect.

Summary of the invention

The utility model purpose is to provide a kind of music charger, can be in charging process or behind full charging, by music or song as prompting, caution and reception and registration effect.

Technical solutions of the utility model: a kind of music charger includes:

One can connect the power-switching circuit of ac power input end;

One in order to the electric current of DC power supply is amplified the current amplification circuit of output, is connected on the dc power output end of AC/DC power change-over circuit;

One discharges and recharges the charging control circuit of putting of instruction in order to execution, is connected with current amplification circuit;

One puts charging indication, is connected on the output of putting charging control circuit;

It is characterized in that: one sends the music circuit of the music or the song sound in order to the control of putting charging control circuit by this, and it comprises a buzzer, and this music circuit is connected on the output of putting charging control circuit.

Wherein, this music charger has on travelling electrical appliance charger construction, the car with charger construction or battery charge holder structure.

The utility model beneficial effect: by said structure, the utility model can be in charging process or behind the full charging, and music circuit drives buzzer and sends promptings such as music or song, caution and pass on sound, has increased practicality in life and enjoyment.

Understand in order to allow the auditor that the utility model is had further, Zi Zuo is as follows with graphic detailed description the utility model.

Embodiment

The charger of a kind of tool music function of the utility model, see also shown in Figure 1, the circuit block diagram of the utility model one preferred embodiment, cooperate shown in Figure 2, the detailed circuit diagram of this circuit block diagram, it includes:

One power-switching circuit 10 is connected to ac power input end (AC INPUT), alternating current is exported in being converted to DC power supply (DC) back, mainly by a full-wave rectifier (D1～D4) form;

One current amplification circuit 20 is connected to the dc power output end that the power-switching circuit 10 of direct current is changeed in this interchange, is amplified back output with the electric current with this DC power supply;

One puts charging control circuit 30, sees through an interactive control switch circuit and is connected with current amplification circuit 20, execution discharges and recharges, regularly, the instruction of indicating;

One output is put charging indication 40, is connected to the output that this puts charging control circuit 30, puts the control of charging control circuit 30 to be subjected to this, whether determine the amplified current of output current amplifying circuit 20, as charging current, again with current delivery to lead-out terminal, to charge;

One music circuit 50, this music circuit 50 is connected on the output of putting charging control circuit 30, put the control of charging control circuit 30 to be subjected to this, whether decision is in charging process or behind the full charging, buzzer 51 on the music circuit 50 sends music or song, as the function of prompting, caution and reception and registration;

Particularly, foregoing circuit includes:

One first electric crystal Q1 is connected to the output of power-switching circuit 10, and this first electric crystal Q1 is a power electric crystal, can add a radiator (not shown) on it, dispels the heat when helping the first electric crystal Q1 conducting; Two controllers (IC1A, IC1B) again, in order to carry out actions such as charging keying, indication, timing, its output is put charging indication 40 with this output and is connected; Another music IC (IC2) is connected to the wherein output of a controller (IC1A); The another second electric crystal Q2, be connected to the output of this music IC (IC2), this second electric crystal Q2 also is connected with the buzzer 51 of music circuit 50, and this second electric crystal Q2 is a power electric crystal, can add a radiator (not shown) on it, dispel the heat when helping the first electric crystal Q1 conducting.

Other sees also shown in Figure 3, embodiment appearance assumption diagram of the present utility model, wherein the plug 101 of these charger 100 1 ends can be plugged on the general socket, to connect civil power, the connection-peg 103 that other end lead 102 is connected can be plugged on the general mobile phone cradle, charges for mobile telephone cell; The charger of the utility model also can have on traveling charger, the car with charger constructions such as charger, battery charge seats, just as long as the power source conversion that the general AC input is imported is the power supply that the DC output is exported, for the charging effect, all can be applicable in the utility model scope.

In sum, the utility model music charger adds devices such as music circuit on general charger, and when being recharged thing in charging process or charge when saturated, charger can send the sound person of prompting, caution and reception and registration; Its practical effect is when unquestionable, and the utility model is never made the city know or seen other publications, meets the regulation of Patent Law, proposes patent application then in accordance with the law.

Claims

1. music charger includes:

One can connect the power-switching circuit of ac power input end;

2. music charger as claimed in claim 1 is characterized in that: this music charger has on travelling electrical appliance charger construction, the car with charger construction or battery charge holder structure.
