RU70437U1 - CAR MAGNETOL WITH REMOVABLE PORTABLE PLAYER ON THE FRONT PANEL USING ENERGY INDEPENDENT SEMICONDUCTOR MEMORY TYPE FLASH - Google Patents

Abstract

The car radio with a removable portable player on the front panel using non-volatile flash memory (flash player) is designed to be able to use the flash player as an independent portable device disconnected from the car radio, and the car LCD (liquid crystal) display and flash -player in a state connected to the car radio. Expands the arsenal of technical tools in automotive electronics.

Description

A car radio with a removable portable player on the front panel that uses non-volatile flash memory (flash player) refers to car electronics and portable sound reproducing technology. The utility model is intended for use as a car radio if the flash player is installed on the front panel. In this state, the car radio allows you to:

- sound reproduction both from internal sound sources (tuner or player of MCH disks), and from a flash player installed on the front panel;

- recording audio files of the MP3, WMA format from the MCHN player into the flash player's memory;

- use of an LCD (liquid crystal) display of a flash player as an LCD display of a car radio.

When disconnecting the flash player from the front of the device:

- the car radio is blocked;

- the flash player contains its own independent battery and supports all the functions of an independent flash player (playing audio files in MP3, WMA format through plug-in portable headphones; recording audio files and image files from a personal computer).

There are no analogues in the utility model when the flash player is connected to the car radio. In the off state, that is, when the utility model is an independent flash player and car radio, analogues for the individual components may be:

- car radio with CD-R players (machine-readable drives) and a removable front panel with controls. As a close analogue, you can select a car radio with a removable panel of the brand SONY CDX - GT200, the source of information is the manufacturer's instructions. This model is capable of reproducing MCH disks with audio data of the MP3, WMA, CD-DA formats and has a removable control panel with a display. Unlike the utility model, the analogs do not have a flash player on a removable front panel, the size of the analog removable panel is 170 × 36 × 18 mm and significantly exceeds the possible maximum dimensions of the removable front panel of a flash player - (up to 85 × 30 × 18 mm - length * width * thickness);

- Portable audio file players with LCD display. The analogue is the Cowon iAudio U2 portable flash player, the source of information is the manufacturer's instructions. This model is equipped with a liquid crystal (LCD) display, USB-interface for data transfer. Supported file formats: audio formats: MP3, OGG, WMA, WAV. Dimensions 73.8 * 25 * 18 mm (length * width * thickness).

Unlike the utility model, no analogues are used as a removable panel and LCD display of the car radio.

The technical result is:

- in the novelty of the device;

- in expanding the arsenal of technical devices for automotive electronics;

- in reducing the dimensions of the removable panel of the car radio in comparison with any manufactured analogues;

- in the use of a removable panel as a portable flash player, in a state disconnected from the main unit of the car radio, unlike any other analogs;

- the ability to record audio data files from the MCH used in the car radio to the flash memory of a portable flash player;

- the possibility of recharging the batteries of a portable flash player from the vehicle’s on-board network.

Due to the variety of designs and sizes of separately manufactured devices - car radios and portable flash players, Fig. 1 shows a possible appearance with a combination of these devices in a utility model.

The design of the utility model differs from the analogue in that a removable non-volatile flash player connected to the car radio is located on the front non-removable panel of the car radio (clause 1 of Fig. 1) (clause 2 of Fig. 1). On a non-removable panel are the controls of the utility model and the front of the tray for loading the MCHN. The removable flash player contains an LCD display, a rechargeable battery and player controls in a state disconnected from the car radio. When connected to the car radio, the LCD of the flash player functions as the LCD of the utility model. The flash player blocks the control of the car radio when it is disconnected from it, thereby performing the anti-theft function. The implementation of the utility model in industrial production is possible provided:

- output of the main controls for the car radio and flash player to the non-removable part of the panel (item 1 in Figure 1);

- replacing the LCD display of the car radio on the front panel to the place of connection of the flash player;

- use of a portable flash player (item 2 of Fig. 1) as a removable panel with an LCD display. The flash player contains independent controls used when disconnected from the car radio.

The current level of microelectronics, the dimensions of the existing analogues of portable flash players with an LCD display (from 70 × 26 × 18 mm - length * width * thickness) and free space for placing the latter on the front panel of the car radio (up to 85 × 30 × 18 mm - length * width * thickness), as well as existing separately connected interfaces for connecting and transmitting data, are sufficient for technical execution.
