Description

The invention relates to devices from the field of radio engineering, in particular, to multimedia systems and is intended for playing audio audio files.

State of the art.

An analogue of the device proposed for patenting is a portable multimedia acoustic wireless system, for example, a device from JBL, Charge-4.

The main functions of the system declared by the manufacturer are:

- a wireless receiver of a signal transmitted via streaming of the Bluetooth protocol, which allows you to broadcast an audio signal from third-party devices that play audio files equipped with a Bluetooth protocol data transmitter;

- 20 hours of battery life using a rechargeable battery that can be recharged via a USB port.

In this case, the JBL device, Charge-4:

- requires charging the built-in battery of the device, full charging time is 4 hours when the battery is fully depleted;

- does not contain a built-in audio file player;

- does not contain a built-in memory card reader;

- does not contain a built-in autonomous power supply that allows using the device without any recharging from third-party power supplies or connecting to third-party power supplies,

which are the main and significant disadvantages of the analogue.

The difference between the claimed technical solution is the lack of a mechanical DC generator analogue, which allows you to use the device without any charging (periodic or constant) from power sources.

Switching tracks is set by mechanical switches and transmitted to the audio file playback device through the device's microcontroller.

Another analogue of the claimed technical solution is a playback device containing a housing, means for reading and writing optical disks, a processor for digital signal processing, a memory device, an editing tool stored in the data memory, a display and an audio output structure, differs from the prototype in that it is equipped with USB - a data transmission interface for peripheral devices, including a serially connected corresponding connector, a port and an additional digital signal processor. The USB connector is made with the ability to connect through it to the USB port of peripheral mainly storage devices. An additional digital signal processor is capable of converting and storing multimedia data on a peripheral storage device by editing (patent for a useful model of the Russian Federation No. 112787, publication date: 20.01.2012).

A significant disadvantage of this analogue is that the description does not disclose how the operation of the device is achieved: from the electrical network, batteries or accumulator, therefore, in this analogue, its multifunctionality is not achieved.

In the claimed invention, there will always be a distinctive feature of the ability to mechanically generate electricity necessary to reproduce a sound signal, as well as switching tracks by mechanically acting on the playback device.

The prototype of the patent pending invention is a portable sound box that includes a main body and a clip. The main body includes a battery to power the portable sound box. Thus, the portable sound module can power itself. The clip is attached to the main body and configured to clip an external object. Thus, the portable sound module can be attached to an external object (US patent No. US20110075877A1, publication date: 2010-06-14).

Significant disadvantages of this prototype are the presence of a battery, which is designed for a certain number of hours of autonomous operation, after which it must be charged, and the battery also has a limited service life.

The objective of the claimed invention is to eliminate the above disadvantages of analogues and prototype.

The technical result of the claimed invention is to expand its functionality and versatility:

- the ability to work in the absence of a constant source of energy, for example, a battery;

- the ability to play sound files located on the internal or removable storage;

- the ability to connect an external audio signal source and mix the signals reproduced by the device and the signal from an external source (for example, connecting a microphone through the standard connector of the device and transmitting the signal to the speakers of the device through an amplifier, while the signal from the microphone can be mixed with the signal reproduced by the device, the so-called . "karaoke" function);

- the ability to charge the batteries of external devices from the built-in generator through a universal connection port, for example, USB ports, etc.;

- the ability to connect and power peripheral devices through a universal connection port, for example, USB ports, etc.;

- the ability to switch tracks without turning on the device, that is, presetting the track without starting the device.

Interactivity and user involvement: the user has the opportunity to feel like a performer of musical song compositions due to complete immersion in the process, which, in terms of the degree of involvement, is similar to playing a musical instrument.

The knob of the generator drive transmits muscular force to the generator core, thereby transferring mechanical energy to the generator to generate electrical energy. The resulting electrical energy through the voltage limiter enters the capacitors and provides electrical power to the circuit of the device.

The microcontroller reads the parameters in accordance with the control program: start / stop and rotation speed of the generator drive, activates the audio file playback device when the drive starts rotating, stops playback when rotation stops, increases the playback volume when the rotation speed increases and decreases when the rotation speed slows down, respectively.

A switching board is a component that controls the power supply of the device modules in the sequence necessary for correct operation.

An audio player is a standard electronic device module for playing audio files that reads information from a memory card inserted into a memory card reader slot.

A mixer is an electronic device designed to sum the audio signals of two channels with the ability to adjust the signal level on each of the channels.

The track number for playback is set by a switch on the control panel and transmitted to the audio file playback device through the microcontroller.

The display shows the serial number of the track being played on the memory card, the values of the rotation speed of the generator drive and the power generated by the generator of electric current, data reading and information transfer to the display is controlled by the microcontroller.
