Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for adjusting a reception volume of a portable telephone.

[0002]

2. Description of the Related Art As a conventional apparatus for automatically adjusting the reception volume of a portable telephone, there is one disclosed in Japanese Patent Application Laid-Open No. Hei 4-82331. This includes a noise sensor for detecting background noise in a usage environment of a mobile phone, a threshold setting unit for setting a threshold of a background noise level by a signal from a keypad, a background noise detected by the noise sensor and a threshold setting unit. A comparison unit that compares the threshold value set in the comparison unit, and a volume setting unit that controls adjustment of the reception volume of the speaker based on the comparison result in the comparison unit, and the reception volume corresponds to background noise of the use environment. It is automatically set, and the receiving volume is adjusted optimally without operating the volume up switch or the volume down switch each time the usage environment changes due to the movement of the user.

As another conventional method for automatically adjusting the reception sound volume, there is one disclosed in JP-A-9-64945. The service detection means detects whether the mobile phone is in the service area of the public base station or the service area of the base unit of the home phone, and always searches for the service state, and receives a call depending on the state. And / or volume setting means for automatically setting the volume of the received sound. In a service area of a public base station where the surrounding noise is relatively large, the ring tone is reduced to increase the receiving volume, and the surrounding volume is relatively increased. In the service area of the base unit, where the noise is small, the ring tone is increased and the reception volume is reduced, thereby eliminating the need for manual volume adjustment according to the usage environment.

[0004]

Among the above-mentioned prior arts, the one described in Japanese Unexamined Patent Publication No. Hei 4-82331 discloses a technique in which the magnitude of background noise detected by a noise sensor is input from a keypad. The threshold value is compared with the comparison unit, and based on the comparison result, the volume setting unit sets the ringtone and the reception volume of the speaker in proportion to the strength of the background noise.

However, in such a configuration, if the background noise is large, the received sound volume is adjusted to be large, and if the background noise is small, the received sound volume is adjusted to be small. The result is that users' willingness to do so can be ignored. To get the user's preferred listening volume, the threshold must be re-entered from the keypad each time the background noise level changes,
There was a problem that operability was extremely poor.

[0006] Further, Japanese Unexamined Patent Application Publication No. 9-64945 discloses whether a user is in a service area in which a user can talk via a public base station or in a service area of a base unit of a home telephone. The service detecting means detects the incoming call and the volume of the incoming and outgoing call is adjusted according to the state.

However, in such a configuration, the volume adjustment is affected by the current position of the user, and the user's will is not respected. In this case, for example, when the user is located in a very noisy place even in the public base station, the voice is canceled by the noise and the call cannot be made.

As described above, in any of the prior arts, the reception volume can be adjusted only by operating the keys and switches on the front of the mobile phone. Therefore, the reception volume is adjusted by a simple operation during a call. There was a problem that it was not possible.

The present invention has been made in view of the above-mentioned problems of the prior art, and does not require troublesome keys or switch operations even during a call, and allows a user to freely receive a desired call. The purpose is to adjust the volume.

[0010]

In order to solve the above problems, a sensor for detecting that a mobile phone has been shaken, a receiver for outputting the voice of the other party during a call, and an output from the receiver. A reception volume control circuit for amplifying the voice of the other party and a processor for controlling a volume amplification factor of the reception volume control circuit based on a detection signal from a sensor are provided.

The sensor has a positive electrode at one end and a negative electrode at the other end. A ball movable between both ends is disposed inside the sensor. The angle sensor changes its output in response to a signal from the sensor, and the processor detects the movement time of the ball when the mobile phone is shaken from the angle sensor output in response to the signal from the sensor.

If the signal input to the processor from the angle sensor when the mobile phone is shaken during a call indicates that the movement time of the ball is within a predetermined time, the volume of the received sound is increased, and Otherwise, the received sound volume is reduced.

[0013] Also, the step of detecting the moving time of the mobile phone, the step of determining the detected moving time, and the step of determining the moving time determine whether the moving time is within a predetermined time. If it is within the time, the receiving sound volume is increased, and if it is not within the predetermined time, the receiving sound volume is decreased.

The sensor is an acceleration sensor for detecting each moving direction when the mobile phone is shaken in the X direction and the Y direction orthogonal to the X direction. When indicating that the mobile phone has been shaken in the X direction, the reception volume is increased, and when the output of the acceleration sensor indicates that the mobile phone has been shaken in the Y direction,
It is characterized in that the receiving volume is lowered.

The processor increases the reception volume if the output of the acceleration sensor shakes the mobile phone during a call and indicates that the moving direction of the ball is in the X direction.
If it indicates the Y direction, the received sound volume is reduced.

Further, the step of detecting the moving direction of the mobile phone, the step of detecting the moving direction detected in the step, and the step of detecting the moving direction are performed. In the case of, the receiving sound volume is increased, and in the case of the Y direction, the receiving sound volume is decreased.

With the above configuration, in the present invention, the reception volume is adjusted by shaking the mobile phone. When an angle sensor is used to detect that the mobile phone has been shaken, the movement of the ball is detected by the angle sensor, and the processor recognizes the time of the shake and recognizes this as a predetermined time. By comparing, the reception volume can be adjusted.

Further, when an acceleration sensor is used, it is possible to detect that the mobile phone is shaken by the acceleration sensor and recognize the direction in which the mobile phone is shaken, thereby adjusting the volume.
Therefore, the received sound volume can be adjusted by a simple operation without feeling bothered during a call.
