Abstract

PROBLEM TO BE SOLVED: To enhance convenience of a communication function by automatically attaining a speaker phone communication state, when an approach detector detects that a person or the like is approaching, at the time of detecting incoming call signals. SOLUTION: A speaker phone means 5 is activated, when an approach detection means 3 detects the approach of the person or an object and is turned into a speaker phone communication state. In the speaker phone communication state, the speaker phone means 5 outputs voice from a communicating party transmitted through a line 1 from a speaker 6 and transmits the voice inputted from a microphone 7, through the line 1 to the communicating party. Also, when a non-communication time measurement means 9 times out, the speaker phone means 5 stops the speaker phone communication state. The speaker 6 rings incoming call tones, while an incoming call detection means 2 detects an incoming call and outputs communication voice (the voice from the communicating party), while the speaker phone means 5 is in the speaker phone communication state.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a telephone device with a speakerphone function according to an embodiment of the present invention. As shown in FIG. 1, the telephone device with a speakerphone function according to the present embodiment includes
And an approach detecting means 3, an approach detecting sensitivity adjusting means 4, a speaker phone means 5, a speaker 6, a microphone 7, a microphone sound pressure measuring means 8, and a non-talking time measuring means 9. . The telephone device with a speakerphone function includes a handset as well as a general telephone, but components not related to such a speakerphone function are not shown.

The line 1 is connected to the incoming call detecting means 2 and the speaker phone means 5. The incoming call detection means 2 detects an incoming call from the line 1. The approach detecting means 3 includes the incoming call detecting means 2
Detects an approach of a person or an object to the telephone device with the speakerphone function while detecting an incoming call. As the approach detecting means 3, various types such as an optical sensor and a sensor using sound can be considered. The type of the sensor may be selected according to the installation location of the telephone device. For example, a sensor used for an automatic door or the like may be used. Further, a plurality of types of sensors may be used in combination to increase the certainty of the approach determination. The approach detection sensitivity adjustment means 4 sets the approach detection means 3 to the sensitivity set by the operator.

The speakerphone means 5 includes the approach detecting means 3
Is activated when it detects the approach of a person or an object, and enters a speakerphone call state. In this speakerphone call state, the speakerphone means 5 outputs voice from the other party transmitted via the line 1 from the speaker 6,
The voice input from the microphone 7 is transmitted to the other party via the line 1. Further, the speakerphone unit 5 stops the speakerphone call state when the non-talk time measuring unit 8 times out. The speaker 6 sounds a ringtone while the incoming call detection means 2 detects an incoming call, and outputs a call sound (voice from a call partner) while the speakerphone means 5 is in a speakerphone call state. Microphone sound pressure measuring means 8
Measures the sound pressure input to the microphone 7, and restarts the non-communication time measuring means 9 when the sound pressure is equal to or more than a predetermined value. The non-communication time measuring means 9 restarts time measurement when the approach detecting means 3 detects the approach of a person or an object and when the microphone sound pressure means detects the microphone sound pressure.

FIG. 2 is a flowchart showing the operation of this embodiment. Hereinafter, the operation of the present embodiment will be described with reference to FIG.

First, when the incoming call detecting means 2 detects an incoming call from the line 1, the speaker 6 starts ringing (steps S1 and S2). Thereafter, while the incoming call detection means 2 detects an incoming call from the line 1, the speaker 6 sounds a ring tone to notify the person of the incoming call (steps S3 to S5).

During the ringing of the ring tone, the approach detecting means 3 detects the approach of a person or an object (step S).
5) When the approach is detected, the speakerphone means 5 is set to the speakerphone call state (step S6), and
Restart the non-talk time measuring means 9 (step S
7). Here, the approach detecting means 3 detects the approach in step S5 with the sensitivity set by the operator in the approach sensitivity adjusting means 4.

The non-communication time measuring means 9 is restarted when the microphone sound pressure measuring means 8 detects a microphone sound pressure of a certain level or more (step S10 → S7), but the microphone sound pressure measuring means 8 is restarted when the microphone sound pressure measuring means 8 has a certain level or more. If the microphone sound pressure is not detected, a timeout occurs after a predetermined time (steps S8 → S10 → S8 →
S10 → S10 → S8 → S9), the speakerphone means 5 is stopped (step S9), and the speakerphone call state ends.
