A portable musical system for caraoke and a cartridge

The invention relates to an autonomous portable music radio device 5 which allows a singer to perform a singing party with a musical accompaniment,

Recorded on this Device, which transmits the singer's song and recorded music by radio to a regular radio tuner.

It is well known that the modern arrangement of musical accompaniment, commonly referred to as the karaoke system, is composed in such a way that the electronic sound system reproduces the lyrics of the song performed by the singer in front of the microphone along with the recorded music accompaniment. The core of the karaoke system is a magnetic tape or disc player for playing music on songs. One can enjoy performing a song of his choice by combining his voice through a microphone with a playable accompaniment of music. Karaoke systems are gaining popularity with many people.

The standard bar-based cocoa system consists of a microphone, a wide band stereo system with a powerful amplifier that allows for steam, an echo generator to improve the voice quality of the artist's voice, and a separate control for the singer to select and synchronize with the song, can select the degree of microphone and music amplification, audio frequency and tempo depending on where the artist is located; and can offer a fairly wide selection of tunes. Some karaoke systems include television monitors for displaying song lyrics so that an artist can read the lyrics while singing [U.S. Patent 5,655,416, G10H 7/00, 5 August 1997. Karaoke system having a playback source with pre-stored data and a music synthesizing source with rev / ritealbe data].

The conventional karaoke system, however, is bulky in terms of music storage components that provide a fairly large selection of songs, a stereo system with an audio amplifier for complete and effective sound mixing and a separate control unit.

A system is needed to move the karaoke system to wherever the performer walks, without any restrictions on the position.

Limitations are avoided by a portable music karaoke system which is closest to the invention and which consists of a memory device with an interface sleeve for connecting special music accompaniment devices (cartridges), a music accompaniment search device with a decoder, a microphone and a device for rebuilding and processing further transmits it to the receiving device [WO 94/24282, G10H 1/36, 24.11.1994. Portable music performance device].

In a known portable music karaoke system according to WO 94/24282, a storage device is a permanent storage device (NA) for storing musical accompaniment data and corresponding numbers in the form of digital signals. The music accompaniment search unit with decoder comprises a microprocessor for performing predetermined operations according to a program stored in the microprocessor's internal memory when the input signals are received from the switching matrix and for selecting the music data stored in the memory by means of a multiplexer and a decoder.

In the renowned portable music karaoke system, the NAI allows you to store up to 1,200 songs by connecting special devices (cartridges) with music accompaniment via the interface sleeve: · The artist has the ability to select a music accompaniment from a large list, not limited to the original, memorized music system. Special gadgets (cartridges) with music on them can be sold, allowing users to buy the music they like, swapping it with friends, expanding their options.

Special devices (cartridges) that provide digital recording for music accompaniment data storage are known [U.S. Patent 4813014, G11C 27/00, 14 03 1989. Digital audio memory system].

/ The closest to the invention is a special device (cartridge) of a portable music system having a permanent memory device for storing music and an interface sleeve for connection to a musical device [GB patent 2249889, G11C 27/00, 20 05 1992. Digital sound source device and external memory catrtidge used therefor].

The disadvantage of known devices - the portable music karaoke system according to WO 94/27282 and the special device (cartridge) of the portable music system according to GB patent 2249889 is that the data stored in the NAI and the corresponding recorded music are protected from unauthorized use which is recorded} infringement of copyright and statutory intellectual property rights.

The invention solves the problem of protecting data that is recorded in musical works by a portable music karaoke system comprising a storage device with an interface sleeve for connecting special devices (cartridge) with a music accompaniment, a music accompaniment search device with a decoder, a microphone and a device and processes the input and playback music accompaniment and passes it to the receiving device, has an additional decoder for interaction with a special device (cartridge) via an inter- connector coupling.

The invention is further solved by the fact that the special device (cartridge) of the portable music system, comprising a permanent storage device for storing music tracks and an interface sleeve for connection to a musical device, has a key encoder connected to the permanent storage device and Interoperability with a portable decoder additional decoder via interface coupler.

A special device (cartridge) for a portable music system may include a board on which a permanent storage device, an interface sleeve and a key encoder are mounted.

A special device (cartridge) of a portable music system may have a housing incorporating a plate.

The special device (cartridge) of the portable music system of the present invention may also differ in that it has a permanent memory device for storing music as an integrated chip.

Each special gadget (cartridges) can accommodate any intended type of music, such as country or pop, can be a collection of the most famous songs or a single singer (a few singers).

A portable music karaoke system can be designed in a housing with a recess into which an interface output is output.

The housing of the special device (cartridge) of the portable music system may be designed to fit in the recess of the portable music system housing.

The device is illustrated in the drawings, in which Fig. 1 shows a portable music system with a special device (cartridge); 2 - Special device.

Portable Musical Karaoke System 1 has memory device 2 with interface sleeve 3 for connecting special devices (cartridge) with music accompaniment 4, music accompaniment search device 5 with decoder 6, microphone 7 and device for rearranging and processing input and playback music accompaniment 8 and device which transmits to the receiving device 9. A feature of a portable music system is that it has an additional decoder 10 for interfacing with a special device (cartridge) via an interface sleeve.

The special device (cartridge) of the portable music system has a permanent memory device 11 for storing music and an interface sleeve 12 for connecting a special device (cartridge) to the musical device.

A feature of the special device (cartridge) 4 of the portable music system 1 is that it has a key encoder 13 connected to the permanent storage device 11 and constructed in such a way that it is possible to interact with the additional decoder 10 of the portable music system 1 music system breaker 3.

The special device (cartridge) may comprise a printed circuit board 14 which is provided with a permanent memory device 11 and an interface sleeve 12 and a key encoder 13.

The special device (cartridge) may comprise a housing 15 which includes a printed circuit board 14.

The device works as follows. A special device (cartridge) 4 is connected via an interface sleeve to a karaoke portable music system 1. According to the command of the music system microprocessor, the encoded digital data read from the IC chip enters the decoder, an additional music system decoder 10, where the data is decoded, processed, converted to analog signals, amplified, fed to a frequency modulator and antenna.

The use of an additional decoder for interaction with a dedicated device (cartridge) via an interface sleeve in a portable music karaoke system and the use of a dedicated encoder in a dedicated device prevents unauthorized access to data stored on a permanent storage device.
