Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibrator control device, in particular, a portable telephone, a PHS (Personal H).
The present invention relates to a vibrator control device for controlling an incoming call vibrator of a mobile communication device such as an andyphone system or a pager (registered trademark) or a portable device such as a pocket watch.

[0002]

2. Description of the Related Art In general, portable telephones and PHSs are equipped with an incoming call vibrator function in consideration of a case where a receiver is in an environment where it is inappropriate to ring an incoming call. Some of these can select a vibration pattern at the time of an incoming call from a plurality of vibration patterns.

On the other hand, recently, a ring tone melody function for playing a melody instead of a ringing tone at the time of an incoming call is called "ringtone (trademark of Tokyo Communication Network Co., Ltd.)" or the like, and has become popular. This function decodes and plays sequence data (musical score format data of music) previously stored in the memory in the mobile phone at the time of an incoming call using a host CPU, a tone generator IC, or the like. However, with the progress of technology, it has gradually shifted to double tone (chord) performance.

Some of the above-described ringing vibrator functions and ringing melody functions can be combined. However, only the sequence data is combined with a simple vibration pattern and not synchronized with the rhythm of the music. It is necessary to secure in advance a performance channel or track dedicated to vibrator control in the file, or to insert data for vibrator control in any of the channels in the sequence data file in advance.

[0005] Also, a partner telephone number notification function is known and has already been put to practical use. A function has been devised for interlocking the selection of the other party's telephone number with the song data and the selection of the color of the illumination LED, but there is no function interlocked with the vibrator function. This is because the ability to discriminate against human rhythm is low, and it is difficult to identify the caller using only a conventional monotonous vibration pattern, and it is not effective even if linked.

[0006]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is not to provide a control based on a simple vibration pattern, but to prepare a control of a vibrator synchronized with a rhythm used in advance by preparing sequence data dedicated to the vibrator control. It is an object of the present invention to provide a vibrator control device which can be realized without any problem.

[0007]

According to the present invention, there is provided a storage device for storing music data, and vibrator control means for controlling the vibrator at a timing determined from the music to be reproduced based on the music data. A vibrator control is provided. Preferably, the vibrator control means controls the vibrator in synchronization with a sound lower than a predetermined threshold included in the music to be reproduced.

Alternatively, the vibrator control means controls the vibrator in synchronization with a predetermined specific tone contained in the music to be reproduced. According to the present invention, there is also provided an envelope detection circuit for detecting an envelope of a music to be reproduced, and a vibrator control device for comparing the detected envelope with a threshold value and outputting a comparison result as a vibrator control signal.

The present invention first provides a vibrator control means capable of synchronizing a rhythm with a music instead of a monotonous vibration pattern. In the present invention, there is no need to prepare dedicated sequence data in advance for vibrator synchronization control. Synchronization here means not only synchronizing a vibration pattern with the tempo of a music piece (for example, a vibration pattern that simply vibrates at the timing of a quarter beat of the music piece), but also with respect to the rhythm expression of the whole music piece. Synchronization is meant. Therefore, even if there is a complicated rhythm pattern, the vibration pattern of the vibrator matches the characteristic accent position of the rhythm.

According to the method of the present invention, there is no need to prepare dedicated sequence data in advance for vibrator synchronization control, and the vibration pattern can be freely selected for a control trigger according to the needs of the user. Also, unlike a monotonous vibration pattern, an incoming call can be sensed in a musical rhythm, so that there is no discomfort. Therefore, in combination with the incoming call vibrator function and the other party's telephone number notification function, it is easy to specify the caller. If this becomes possible, the caller can be identified by the vibration pattern even in a place where it is difficult to make the incoming call ringing sound.

FIG. 1 is a block diagram showing the configuration of an embodiment of a vibrator control device according to the present invention. FIG.
, When the music reproduction mode is set, the music data reproduction sequencer 10 stores, for example, MIDI (Musical Instrument) stored in the storage device 12.
A sound source waveform generator (MI) via the sound source controller 14 based on music data in a Digital Interface format
DI sound source) 16. The output from the sound source waveform generator 16 is synthesized in the mixer 18 and sent to a speaker (not shown) as output performance data.

On the other hand, when set to the vibrator control mode, the music data reproduction sequencer 10 determines the control timing of the vibrator from the music data stored in the storage device 12 according to a trigger condition specified by the user, and Output as a signal. As trigger conditions specified (set) by the user, for example, the following can be considered. 1) Threshold control of bass sound and the like Specifying a specific channel (or voice) or track (ie, specific instrument) of MIDI data,
The threshold of the certain note number (corresponding to the pitch) is set. The vibrator vibrates when a note-on trigger occurs at a pitch lower than that.

For example, as shown in FIG. 2A, when "F2" is specified as the threshold value for the channel of the base tone color, as shown in FIG. A vibration pattern can be obtained. Among the bass sounds, those having relatively high pitches include those of a fast passage used as an ornamental sound, but since such a sound does not follow a vibration pattern, it is suitable for synchronizing the performance rhythm with the vibrator function.

In this case, the vibration time is preferably controlled so as to be a slightly shorter time (for example, 3/4) set in advance with respect to the gate time of the target note. 2) Key number (note number) control of drum sound and the like A channel or track having a specific tone color arrangement is designated, and a certain key number (a plurality of designations are possible) is set. The vibrator vibrates at the time of the note-on trigger of the tone assigned to the pitch.

For example, when a channel to which a drum map array is assigned is designated as shown in FIG.
By setting the key number assigned to the kick and the key number assigned to the snare drum as shown in (a), FIG. 3 (b) synchronized only with the kick and snare
A vibration pattern as shown in FIG. Most of the rhythmic expressions centered on popular songs are composed of kicks and snares, and are suitable for synchronization with a vibrator function for sensing the skeleton of the song.

In this case, the vibration time is slightly shorter than the gate time of the eighth note or sixteenth note obtained from the tempo of the music.
It is preferable to control so as to be a fixed time (for example, 3/4). 3) Control by Peak Detection As shown in FIG. 4, an envelope detection circuit 20 is arranged at the subsequent stage of the mixer 18 for outputting performance data (FIG. 5A), and the detected envelope is compared with a threshold value in a comparison circuit 22. A comparison is made (FIG. 5B), and the vibrator is vibrated for a time during which the envelope peak exceeds the set threshold (FIG. 5C).

Tones (drum sounds and bass sounds) in which spectrum power is concentrated in the low frequency range have a relatively large amplitude, and in many music pieces, such tones express a main rhythmic feeling. Therefore, in this configuration, when the peak obtained from the envelope detection circuit exceeds a preset threshold value, it is synchronized with the basic rhythm expression of the music, and the vibrator vibrating in synchronization with the peak position is used as the rhythm of the music. Since the expression is well preserved, it is suitable for synchronizing with the vibrator function for detecting the skeleton of the song.

As shown in FIG. 6, a filter 24 may be provided between the output data and the envelope detection circuit 18. Effective filters are a low-pass filter (LPF), a band-pass filter (BPF), and a band-reject filter (BRF). In the case of LPF, peaks are detected after emphasizing the lower frequency range, so even if there is a tone in which a large amount of power is concentrated only in the middle and high frequency range, which is often unrelated to the basic rhythm expression of the music, In this case, the case where the peak exceeds the threshold is ignored, so that it is more suitable for synchronization with the vibrator function.

When combined with the other party's telephone number notification function, the storage device 12 stores the other party's telephone number list and a plurality of music data. Each of the other party telephone numbers in the list is associated with any one of the plurality of songs. When a call is received, the other party's phone number notified from the other party's phone number notification function is compared with the other party's phone number list. If there is no matching telephone number, the vibration of the vibrator is controlled by a predetermined song and a vibration trigger. If there is a matching phone number, the song associated therewith is checked for a vibration trigger. If not, the vibration of the vibrator is controlled by a predetermined music and a vibration trigger. If so, the vibration of the vibrator is controlled by the selected music and the vibration trigger. The receiver perceives the vibration and recalls a song set in advance, thereby enabling the caller to be specified through the incoming call vibrator function. Since the music is recalled as compared with a simple vibration pattern, it is easier to imagine the caller.

[0020]

As described above, according to the present invention, it is possible to control a vibrator synchronized with a tune informing of an incoming call or the like, and it becomes easy to specify a caller by combining the vibrator with a destination number notification function. These can be realized without preparing data dedicated to vibrator control in advance.
