Abstract

The utility model relates to a vehicle receiving / playing device composed of an MP3 player. The utility model is composed of a front box and a rear box, wherein the front box has the functions of the MP3 player and a radio; a power amplification section is arranged on the rear box; the front box is connected with the rear box through movable clasps (21); front box circuits (6) and rear box circuits (10) are connected together through electric wire plugs (8) and (9). When MP3 programs are needed to be stored, the front box can be taken off and the utility model can be connected with a computer through a USB interface so that the files can be downloaded from the computer and stored in an MP3 player memory inside the front box (a panel box). While the utility model is in use, the MP3 programs or radio station programs are inputted to loudspeakers inside a vehicle through a power amplification circuit inside the rear box.

Description

The MP3 cassette car radio

Affiliated technical field:

The utility model relates to a kind of novel MP3 cassette car radio.

Present known cassette car radio is made up of broadcast receiver and magnetic tape sound reproducer, or is made up of broadcast receiver and CD-ROM device, and these two kinds of structures all have certain deficiency, no matter is tape or CD, and its quality and life-span are not fine.

The purpose of this utility model is to provide a kind of radio and tape player of MP3 function, and it both can play MP3, also can the broadcast listening program of radio station.The user can download the program of oneself liking from computer, is saved in this MP3 cassette car radio.This equipment is by closure plate (4) before the panel (1), panel back cover (2), can (3), can, LCD panel (5), circuit board (6), USB joint (7), front and back box power lugs (8) and (9), the button formations such as (11) of various buttons, loading and unloading panel box on back box circuit board (10), the panel.

Fig. 1 is the front view of this equipment

Fig. 2 is the A---A cross section view of Fig. 1

The utility model product at first turns on the power switch (12) in use, and (example MP3), at this moment, clicks function selecting key (13), demonstrates another kind of function (example, radio reception) on the LCDs (5) to demonstrate a kind of function on the LCDs (5).When selecting the MP3 program or selecting the radio reception frequency, click button (14), its effect is " a last program " or " a last frequency ".Click button (15), its effect is " next program " or " next frequency ".Volume is controlled by button (16) and (17), pins button (16) volume and just strengthens continuously, pins button (17), and volume just reduces continuously.

Embodiment: make panel (1) with the ABS engineering plastics, panel back cover (2), closure plate (4) before the back box, back box iron-clad (3), iron plate pressing and bending with 0.8MM forms, the master element of MP3, memory element, display element, wireless element all is installed on the interior circuit board (6) of panel box, master switch button (12), volume increases button (16), volume reduces button (17), pause button (18), function selecting button (13), automatic channel search button (19), a last program button (14), next program button (15), system is provided with button (20), finish by touch-switch, USB interface (7) is connected on the circuit board (6).Power amplifier is made on the circuit board (10) in the back box, so just, forming back box is the power amplifier of a cover cassette car radio, front cabinet is the MP3 of the complete band function of radio receiver of a cover, and front cabinet can be fixed on a whole set of front cabinet (MP3, radio reception) on the back box by button bit 2a and movable tongue (21).When needs deposit program in to MP3, only need toggle (11) is stirred left, movable tongue (21) just can inwardly contract, thereby throw off with back box, it after front cabinet takes off a complete MP3 machine, as long as front cabinet is connected with computer by USB interface (7), just the program in the computer can be deposited in the MP3 memory of front cabinet.When front cabinet is buckled into that closure plate (4) is gone up before the back box again, whole system just can have been worked again, the circuit of front cabinet (6) links to each other with the circuit (10) of back box with (9) by plug (8), spring (22) withstands movable tongue moving (21), make it enter tightly to fasten the 4b place, wire harness (23) is incorporated into the power supply of automobile in this radio and tape player, simultaneously with the audio signal output of this radio and tape player in car horn, back box is fixed in the automobile instrument.
