JPH05153201A - Control system for incoming sound volume of portable telephone set - Google Patents

Abstract

PURPOSE:To prevent the injury of ears owing to a large incoming call sound at the time of the incoming call when a portable telephone set is placed near the ears and to shorten time till the incoming call sound comes to large sound volume by setting the incoming call sound to prescribed sound volume when the number of incoming call sounds is less than the number of setting times, and setting the incoming call sound to arbitrary sound volume when it is larger than the number of setting times. CONSTITUTION:When the incoming call is detected, an incoming call sound detection part 6 detects an incoming call sound signal generated from an incoming call sound generation part 1 and a counter 7 counts the number of the incoming call sounds. When the number of the incoming call sounds is less than the previously set number in a comparator 8, a switch 3 is connected to the terminal of 'a' and it is connected to the terminal of 'b' when it is larger than the previously set number. A fixed attenuator 2 decides the sound volume of the incoming call sound when the number of the incoming call sounds is less than the previously set number. A variable attenuator 5 decides the sound volume of the incoming call sound when the number of the incoming call sounds is larger than the number of previously set number. A user can arbitrarily set it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring tone volume control system for a telephone, and more particularly to a ring tone volume control system for a portable telephone.

[0002]

2. Description of the Related Art In the conventional ring tone volume control system for mobile phones, as shown in FIG. 3, a user sets a ring tone generated by a ring tone generator 1 to an arbitrary volume through a variable attenuator 5. , The speaker 4 outputs a ring tone. FIG. 4 shows the change of the ring tone in this case over time. The volume of the ring tone set as shown in FIG. 4 continues to maintain a constant volume over time. Further, in another example of the ring tone volume control system of the conventional mobile phone, the variable attenuator 5 shown in FIG. 3 is changed in accordance with the passage of time, and the volume of the ring tone is gradually increased with the passage of time. It is configured to do. FIG. 5 shows the change of the ring tone in this case over time. As shown in FIG. 5, the ring tone has a relatively low volume immediately after the incoming call is detected, and the ring tone gradually increases as time elapses. Is the maximum value for that mobile phone.

[0003]

Since a mobile phone is literally carried and carried around, it is necessary that the ring tone when a call is detected in a noisy place such as a city is loud. In the conventional ring tone volume control system for a mobile phone, when the control as shown in FIG. 4 is first performed, the variable attenuator 5 is used to adjust the maximum volume to satisfy the above condition. However, when an incoming call is received while the mobile phone is in the ear in this state, the loud ring tone causes an obstacle to the ear. Therefore, a ring tone volume control system that prevents the danger to the ears and has a large ring tone gradually raises the volume as shown in FIG. 5 and raises the volume to the maximum. It is a method. However, this method has a drawback that it takes too long to reach the maximum volume of the mobile phone.

The present invention has been made in view of the above problems, and in the ring tone volume control system of a mobile phone, there is a possibility that an ear may be disturbed by a loud ring tone when an incoming call is received while the mobile phone is at the ear. It is an object of the present invention to provide a ring tone volume control system for a mobile phone, which is capable of preventing the ring tone from reaching a certain level of volume and shortening the time required for the ring tone volume control system for a conventional mobile phone.

[0005]

A ring tone volume control system for a mobile phone according to the present invention comprises a ring tone generation unit, a unit for detecting a ring tone signal generated from the ring tone generation unit, and a number of ring tones. A means to count and a means to determine whether the number of ringtones is more or less than the set number, and if the number of ringtones is less than the set number, switch to a preset volume, and if the number of ringtones is more than the set number Has means for switching to an arbitrary volume set by the user.

[0006]

In the ring tone volume control system for a mobile phone according to the present invention, when the number of ring tones detected by the ring tone detecting means is less than or equal to the set number, a ring tone with a relatively low volume preset is generated. If the number of detected ringing tones exceeds the set number of times, a ringing tone of a relatively large volume set by the user is generated, so that the user of the mobile phone according to the present invention holds the mobile phone at his or her ear. When an incoming call arrives, the incoming call can be detected with a comparatively small ringtone, so it is possible to prevent damage to the ears, and when an incoming call is detected in a noisy place such as in the city, comparison after the set number of times The incoming call can be detected in a shorter time than the conventional ring tone volume control system of a mobile phone by using a relatively loud ring tone.

[0007]

Embodiments of the present invention will now be described with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a ring tone volume control system of a mobile phone according to an embodiment of the present invention. First,
When an incoming call is detected, the ringtone signal generated from the ringtone generator 1 is detected by the ringtone detector 6, the number of ringtones is counted by the counter 7, and the number of ringtones is less than or equal to the number preset by the comparator 8. In that case, the switch 3 is connected to the “a” terminal, and if the number of times is greater than the preset number, the switch 3 is connected to the “b” terminal. Here, the fixed attenuator 2 determines the volume of the ringtone when the number of ringtones is less than or equal to the preset number, and the variable attenuator 5 determines the number of ringtones from the preset number. It determines the volume of the ringtone when the volume becomes large, and can be set arbitrarily by the user.

FIG. 2 is an example of a graph showing the change over time of the ring tone in the ring tone volume control system of the mobile phone according to the embodiment of the present invention. In this embodiment, for example, if the number of times of setting in the comparator 8 is set to “2”,
Even if the ring tone volume setting set by the user in the variable attenuator 5 is set to "max" shown in FIG. 2, the ring tone volume for the first and second times becomes "min" and the ring tone volume for the third and subsequent times. Is “max”. As described above, when the user of the mobile phone according to the present embodiment receives an incoming call while the mobile phone is at his / her ear, the incoming call can be sensed by the first and second relatively small ringing tones, and the incoming call is added to the ear. Can prevent obstacles. Further, when an incoming call is detected in a noisy place such as a city, the incoming call can be detected in a shorter time than the ring tone volume control system of the conventional mobile phone by the relatively loud incoming sound after the third time.

In this embodiment, the volume of the ringing tone less than the third time is set to "min", but it goes without saying that the number of times and the volume can be set arbitrarily.

[0011]

As described above, according to the ring tone volume control system for a mobile phone according to the present invention, the volume of the first several times of the ring tone becomes a volume below a certain value regardless of the user's setting. By doing so, it is possible to improve the safety of the human body, especially the ear. Also, by switching to a relatively loud ringtone set by the variable attenuator after a certain number of ringtones with a fixed volume, a large ringtone volume is required for use in the city. The mobile phone satisfies the conditions for a mobile phone, and can detect an incoming call in a shorter time than the ring tone volume control method of the conventional mobile phone.
