Music reproducing apparatus and method and telephone terminal device

Abstract

In a music reproducing apparatus, a timbre data memory has a limited capacity for storing timbre data corresponding to a first number of timbres, which is less than a second number of timbres reserved in a data source. An interface can be operated to transfer the timbre data from the data source to the timbre data memory so that the timbre data memory stores the transferred timbre data. A score data memory stores score data representing a music piece. A tone generator is set with a tone generating parameter derived from the score data stored in the score data memory for generating tones of the music piece. A performance controller interprets the score data to read out timbre data designated by the score data from the timbre data memory for setting the tone generator with the read timbre data so that the tone generator can generate the tones having timbres specified by the score data. Further, a memory monitor detects when a vacant area is created in a limited space of the score data memory upon sequential retrieval of the score data for operating the interface to load another part of the score data into the vacant area, thereby enabling the tone generator to continue the generating of the tones of the music piece.

Description

technical field [0001] The present invention relates to a music playing device and a music playing method suitable for use in a car phone or a portable phone. Background technique [0002] In portable telephone systems such as PDC (Personal Digital Cellular Telecommunications System) or PHS (Personal Handyphone System) known as analog or digital cellular systems, when a call arrives, the telephone terminal device will ring to alert the user . Traditionally, reminders have been accomplished by beeps, but since beeps are harsh noises, music has recently been used instead of beeps. [0003] Conventional telephone terminal devices of the above type can generate melodies, but the melodies they generate are far from being of satisfactory quality. [0004] In order to solve this problem, it is considered that an effective way is to adopt a music playback device with an automatic performance function. Such a conventional music playing device capable of automatic performance inclu...

Problems solved by technology

[0007] However, melody IC has only a small storage capacity of sound quality data ROM

The storage capacity of the tone quality data ROM is so small that the number of parameters and the kinds of tone quality data are limited, making it difficult to generate high-quality tones or a variety of tones

[0008] In addition, because the memory capacity of the score data ROM of the melody IC is very small, the number of melodies that can be stored and the length of the melodies to be played are limited.

The storage capacity of the music score data ROM is so small that it cannot store a large amount of music data required to play high-quality melodies, so, except for some low-quality melodies, other melodies cannot be played
