DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having a speakerphone (hands-free) function capable of talking with another party without having a handset.

[0002]

2. Description of the Related Art Conventionally, there is known a telephone having a speakerphone function that allows a user to talk with a partner while the telephone is placed on a telephone body without a handset. In a telephone having the speakerphone function, a microphone and a speaker for a speakerphone call are built in the telephone body separately from a microphone and a speaker for a handset call.

When performing either a handset call or a speakerphone call, a microphone and a speaker built in the handset or a microphone and speaker built in the telephone body are manually switched and selected by operating switches and buttons. I was

In a telephone having such a speakerphone function, it is necessary to separately provide two microphones and speakers for a handset call and two microphones and speakers for a speakerphone call. There was a problem that the size was increased.

Therefore, the microphone and speaker built into the handset can be used as the microphone and speaker for speakerphone calls, and the handset is placed on the telephone body with the microphone and speaker side of the handset facing upward. Devices that realize a speakerphone function with one microphone and one speaker have been considered.

[0006]

However, in the above-mentioned conventional telephone, it is necessary to change the input / output level and the directivity of the audio signal between the handset call and the speakerphone call. It is necessary to manually switch between the mode and the speakerphone call mode, which is inconvenient.

The present invention has been made in view of the above points, and has as its object to provide a telephone which can automatically switch between a handset call mode and a speakerphone call mode.

[0008]

According to a first aspect of the present invention, there is provided a telephone capable of performing a handset call or a speakerphone call using a microphone and a speaker of the handset. Detecting means for detecting whether the handset is placed on the phone body with the microphone and speaker side facing up, or whether the handset is placed on the phone body with the microphone and speaker side facing down; When it is detected that the handset is placed on the telephone body with the microphone and the speaker facing upward, the mode is switched to the speakerphone call mode.

Thus, the speakerphone function can be automatically turned on depending on the orientation of the handset with respect to the telephone body, so that the handset call mode is changed to the speakerphone call mode, and the speakerphone call mode is changed to the handset call mode. It is not necessary to perform switching manually such as a switch operation, and the usability can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the telephone according to the present invention will be described below with reference to FIGS. here,
FIG. 1 is a schematic perspective view showing a telephone call of the embodiment of the present invention during a speakerphone call, FIG. 2 is a schematic perspective view of the telephone of the embodiment showing a line disconnection, and FIG. (A) Schematic perspective view showing, (b)
FIG. 4 is a schematic side cross-sectional view, FIG. 4 shows a telephone set of the present embodiment at the time of a handset call, (a) a schematic perspective view, (b) a schematic side cross-sectional view, and FIG. 1A is a schematic perspective view, and FIG.

In the drawing, 1 is a telephone body, 2 is a handset for transmitting and receiving, 3 is a microphone built in the handset 2 for transmitting, 4 is a speaker built in the handset 2 for receiving, 5 is a group of operation buttons for executing dialing and various telephone functions, 6 is a display unit for displaying various information, 7 is a hook switch for connecting and disconnecting a line, and 8 is a handset 2 for the telephone body 1. A speakerphone switch that detects the installation state and turns on / off the speakerphone function.

That is, in the telephone according to the present embodiment, the speakerphone switch 8 allows the handset 2 to be placed on the telephone body 1 with the microphone 3 and the speaker 4 facing upward, or the microphone 3 and the speaker 4 facing downward. To detect whether the handset 2 is placed on the telephone body 1 and automatically switch on / off the speakerphone function according to the detection result.

The operation of the telephone constructed as described above will be described. First, at the time of normal line disconnection,
As shown in (a), the handset 2 is placed on the telephone body 1 with the microphone 3 and the speaker 4 facing downward. In this state, as shown in FIG. 3B, the hook switch 7 is depressed by the handset 2 to disconnect the line, and the speakerphone switch 8 is not depressed, so that the speakerphone function is turned off.

In a handset call, FIG.
As shown in (2), the user holds the handset 2 in his / her hand, puts the microphone 3 on his / her mouth and the speaker 4 on his / her ear, and makes a call. In this state, the hook switch 7 and the speakerphone switch 8 are not pressed as shown in FIG.
The line connection state is established, and the speakerphone function is turned off.

Furthermore, during a speakerphone call, FIG.
As shown in (a), with the microphone 3 and the speaker 4 facing upward, the handset 2 is placed on the telephone body 1, and the microphone 3 and the speaker 4 perform transmission from a remote place. In this state, as shown in FIG. 5 (b), the hook switch 7 is not pressed, so that the line is connected, and the speakerphone switch 8 is pressed by the handset 2 to turn on the speakerphone function.

As described above, according to the present embodiment, depending on the installation orientation of the handset 2 with respect to the telephone body 1,
The speakerphone function can be automatically switched on / off, and there is no need to manually switch from handset call mode to speakerphone call mode or from speakerphone call mode to handset call mode by operating a switch. Therefore, usability can be improved without imposing a burden on the operator.

In the above-described embodiment, the mechanism using the mechanical switch 8 as the means for detecting the installation direction of the handset 2 has been described. The used one may be adopted, and the present invention is not limited to this.

[0018]

Since the telephone according to the first aspect of the present invention has the above-described configuration, the speakerphone function can be automatically turned on according to the installation orientation of the handset with respect to the telephone main body. It is not necessary to manually switch from the handset call mode to the speakerphone call mode and from the speakerphone call mode to the handset call mode by operating a switch or the like, so that usability can be improved.
