ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a portable telephone set, particularly, to a technique of generating a calling sound or an alarm sound. More particularly, audio signal is input from a microphone so as to be used as the calling sound or the alarm sound of the portable telephone set.
As shown in
FIG. 3
, in a conventional portable telephone set, its calling sound or alarm sound is outputted as follows: That is, the calling sound or alarm sound is set up in a melody generating unit
103
in advance. In response to the arrival of a calling signal, a CPU
104
instructs the melody generating unit
103
to generate a particular sound, which is outputted through an amplifier
102
and a loud-speaker
101
.
In the case where the CPU
104
forms the combination of particular sounds on the basis of data inputted through a key, a memory
105
transmits data on the combination of sounds to the CPU
104
, and the latter
104
forms the combination of sounds and instructs the melody generating unit
103
.
In the above-described calling sound or alarm sound generating method, sounds determined inside the portable telephone set or the combinations of sounds are used, or the combinations of calling sounds or alarm sounds inputted through the key are used. Therefore, only the particular calling sound or alarm sound is outputted; that is, selection of the calling sound or alarm sound is narrow.
SUMMARY OF THE INVENTION
Accordingly, an object of the invention is to eliminate the above-described difficulties accompanying a conventional portable telephone set. More specifically, an object of the invention to provide a portable telephone set which is so designed that, in the generation of the calling sound or alarm sound thereof, an audio signal is inputted through a microphone, and is used as a calling sound or alarm sound, so that selection of the calling sound or alarm sound is wide.
In order to solve the above-described problem, in the invention, for instance an audio signal is inputted through a microphone and stored in the portable telephone set, and the audio sound thus inputted is utilized as a calling sound or alarm sound.
Hence, in addition to a calling sound or alarm sound which has been fixed in a portable telephone set, many kinds of calling sounds or alarm sounds can be produced; that is, selection of a calling sound or alarm sound is widened as much.
Particularly, according to first aspect of the invention, a digital portable telephone set comprises: input means for amplifying an input audio signal which is inputted through a microphone; conversion means for subjecting the input audio signal amplified by the input means to analog-to-digital conversion; compressing means for compressing the input audio signal converted by the conversion means; and memory means for storing the input audio signal which has been compressed by the compressing means; control means for specifying the input audio signal stored, in the case where a input audio signal stored is used as a calling sound when the portable telephone set receives a calling signal; decompressing means for decompressing the input audio signal which is taken out by the control means; amplifier means for amplifying the input audio signal which has been decompressed by the decompressing means; and notifying means for notifying, as a calling sound, a called party of the input audio signal amplified by the amplifier means.
That is, sounds which can be utilized as calling sounds or alarm sounds are inputted through the microphone and stored to widen the selection of kinds of sound.
Preferably, in the portable telephone, in the case where, when the input audio signal is stored, a plurality of inputs are stored, the control means specifies storing locations.
In the invention, too, sounds which can be utilized as calling sounds or alarm sounds are inputted through the microphone and stored to widen the selection of kinds of sound.
More preferably, in the portable telephone set, the input audio signal thus stored is reproduced, and notifies a called party, as an alarm sound of the telephone set, of the input audio signal thus reproduced.
Similarly as in the case of the calling sound, the selection of kinds of alarm sound is widened.
More preferably, in the portable telephone, an audio signal inputted through the microphone which has been stored and reproduced is used as a calling sound of the telephone set, and the audio signal inputted through the microphone which has been stored and reproduced is also used as an alarm signal of the telephone set.
Accordingly, the selection of kinds of sound which can be utilized as calling sounds or alarm sounds is widened.
Further, according to the second aspect of the invention, a digital portable telephone set comprises: input means for amplifying an input audio signal which is inputted through a microphone; A/D (analog-to-digital) conversion means for subjecting the input audio signal amplified by the input means to analog-to-digital conversion; memory means for storing the input means converted by the conversion means; control means for specifying the input audio signal stored, in the case where a input audio signal stored is used as a calling sound when the portable telephone set receives a calling signal; D/A conversion means for subjecting to digital-to-analog conversion which is taken out by the control means; amplifier means for amplifying the input audio signal which has been converted by the D/A conversion means; and notifying means for notifying, as a calling sound, a called party of the input audio signal amplified by the amplifier means.
In this invention, too, the selection of kinds of sound which can be utilized as a calling sound or alarm sound is widened.
Preferably, in the case where, when the input audio signal is stored, a plurality of inputs are stored, the control means specifies storing locations.
In the portable telephone set, sounds which can be utilized as calling sound or alarm sounds are inputted through the microphone and stored, to widen the selection of kinds of sound.
More preferably, the input audio signal thus stored is reproduced, and notifies a called party, as an alarm sound of the telephone set, of the input audio signal thus reproduced.
With the portable telephone set, similarly as in the case of the calling sounds, the selection of kinds of alarm sound can be widened.
More preferably, an audio signal inputted through the microphone which has been stored and reproduced is used as a calling sound of the portable telephone set, and the audio signal inputted through the microphone which has been stored and reproduced is also used as an alarm signal of the telephone set.
With those means, selection of kinds of sound which can be utilized as calling sounds or alarm sounds can be widened.
Furthermore, according to third aspect of the invention, a digital portable telephone set comprises: memory means for storing a sound signal of a calling party which is received from the calling party; control means for specifying the audio signal of the calling party thus stored, in the case where the sound signal of the calling party thus stored is used as a calling sound when the portable telephone set receives a calling signal; D/A conversion means for subjecting to digital-to-analog conversion which is taken out by the control means; amplifier means for amplifying the audio signal of the calling party which has been converted by the D/A conversion means; and notifying means for notifying, as a calling sound, the called party of the audio signal of the calling party amplified by the amplifier means.
In the invention, too, selection of kinds of sound which can be utilized as calling sounds or alarm sounds can be widened.
Preferably, in the portable telephone set, the audio signal of the calling party thus stored is reproduced, and notifies a called party, as an alarm sound of the portable telephone set, of the audio signal thus reproduced.
With the portable telephone set, similarly as in the case of the calling sounds, selection of kinds of alarm sound is widened.
