Abstract

In a portable telephone set, an input audio signal such as an audio signal is received through a microphone (111), and is then amplified by an amplifier (112). The output of the latter (112) is applied through an analog-to-digital converter (113) to a DSP (301), where it is compressed and stored in a memory (303) with the aid of a CPU (302), or it is stored therein as it is. Here, an audio signal from outside which is stored in the portable telephone set can be used as a calling sound or alarm sound. Therefore, selection of calling sounds or alarm sounds in the portable telephone set of the invention is wider than in the conventional one.

Claims

1. A digital portable telephone comprising:

input means for inputting an analog audio signal;

amplifying means for amplifying said analog audio signal into an amplified audio signal;

A/D conversion means for converting said amplified audio signal into a digital audio signal;

compressing means for compressing said digital audio signal into a compressed audio signal;

memory means for storing said compressed audio signal as a stored audio signal, for storing an alarm sound, and for storing a melody;

control means for selecting an alarm signal for automatically notifying a user of an alarm condition, said alarm condition being different from the arrival of a call, wherein said alarm signal is one of said melody, said alarm sound and said stored audio signal;

decompressing means for decompressing said stored audio signal selected by said control means into a decompressed audio signal;

D/A conversion means for converting said decompressed audio signal, said alarm sound, or said melody into a notification signal;

amplifying means for amplifying said notification signal into an amplified notification signal; and

notifying means for annunciating said amplified notification signal to the user to notify the user of the alarm condition, wherein, if said control means selected said stored audio signal as an alarm signal, said amplified notification signal resembles said analog audio signal.

2. A digital portable telephone comprising:

input means for inputting an analog audio signal;

amplifying means for amplifying said analog audio signal into an amplified audio signal;

A/D conversion means for converting said amplified audio signal into a digital audio signal;

compressing means for compressing said digital audio signal into a compressed audio signal;

memory means for storing said compressed audio signal as a stored audio signal, wherein said memory means stores a plurality of stored audio signals, said memory means also for storing an alarm sound, a calling sound, and a melody;

control means for selecting one of said stored audio signals, said melody, and said calling sound for notifying a user of the arrival of a call, and further for selecting another one of said stored signals, said melody, and said alarm sound for automatically notifying the user of an alarm condition different from the arrival of a call;

decompressing means for decompressing said stored audio signal selected by said control means into a decompressed audio signal;

D/A conversion means for converting said decompressed audio signal, said alarm sound, said calling sound, or said melody into an analog notification signal;

amplifying means for amplifying said analog notification signal into an amplified notification signal; and

notifying means for annunciating said amplified notification signal to the user, wherein, if said control means selected said stored audio signal as a notification signal, said notification signal resembles said analog audio signal.

3. A digital portable telephone comprising:

receiving means for receiving a notification sound signal from a calling party other than a user of the digital portable telephone;

memory means for storing said notification sound signal as a stored notification sound signal, for storing a calling sound, and for storing a melody;

control means for selecting one of said stored notification sound signal, said calling sound, and said melody for notifying a user of the arrival of a call;

D/A conversion means for converting said stored notification sound signal, said calling sound, or said melody into an analog notification signal;

amplifying means for amplifying said analog notification signal into an amplified notification signal; and

notifying means for annunciating said amplified notification signal to the user for notifying the user of the arrival of a call.

4. The digital portable telephone of claim 3 wherein

said memory means stores a plurality of stored sound signals, and further wherein

said control means is for selecting one of said stored sound signals for notifying a user of the arrival of a call, and further for selecting another one of said stored sound signals for notifying a user of an alarm condition different from the arrival of a call; and still further wherein

said notifying means is for notifying the user of said alarm condition or of the arrival of a call.

5. The digital portable telephone of claim 3 wherein the step of notifying a user of the arrival of a call is for a call initiated by the calling party.

6. A digital portable telephone comprising:

receiving means for receiving a notification sound signal from a calling party other than a user of the digital portable telephone;

memory means for storing said notification sound signal as a stored notification sound signal, for storing an alarm sound, and for storing a melody;

control means for selecting one of said stored notification sound signal, said alarm sound, and said melody for notifying a user of an alarm condition, said alarm condition different than the arrival of a call;

D/A conversion means for converting said stored notification sound signal, said alarm sound, or said melody into an analog notification signal;

amplifying means for amplifying said analog notification signal into an amplified notification signal; and

notifying means for annunciating said amplified notification signal to the user for notifying the user of the alarm condition.

7. A digital portable telephone comprising:

input means for inputting an analog audio signal;

amplifying means for amplifying said analog audio signal into an amplified audio signal;

A/D conversion means for converting said amplified audio signal into a digital audio signal;

compressing means for compressing said digital audio signal into a compressed audio signal;

memory means for storing said compressed audio signal as a stored audio signal, for storing a calling sound, and for storing a melody;

control means for selecting said stored audio signal a call arrival signal for notifying a user of the arrival of a call wherein said call arrival signal is one of said melody, said calling sound and said stored audio signal;

decompressing means for decompressing said stored audio signal selected by said control means into a decompressed audio signal;

D/A conversion means for converting said decompressed audio signal, said calling sound, or said melody into a notification signal;

amplifying means for amplifying said notification signal into an amplified notification signal; and

notifying means for annunciating said amplified notification signal to the user to notify the user of the arrival of a call, wherein, if said control means selected said stored audio signal as a call arrival signal, said amplified notification signal resembles said analog audio signal.
