Embodiment
For described feature and advantage of the present invention can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
As mentioned above, the invention provides a kind of communication device.The audio signal reception device of this communication device has omni-directional and directional microphone, concerns to use omni-directional microphone or directional microphone by the position between the body of audio signal reception device and communication device.Below the details of communication device will be described by means of embodiment.
Figure 1 shows that a kind of communication device according to one embodiment of the invention.Communication device 100 has a body 102 and an audio signal reception device 104.Body 102 has the loud speaker 102a of the usefulness of amplifying, and the surperficial thereon usefulness for user's operation of key zone 102b is set.Audio signal reception device 104 is articulated on the body 102 with rotating shaft 106, so audio signal reception device 104 can turn to the position of user's demand with respect to body 102.This communication device 100 can be a telephone set or conference communications device etc.
In order to make communication device 100 adapt to the radio reception demand of different situations, audio signal reception device 104 is provided with omni-directional microphone 104b and directional microphone 104c, and borrows the MIC of audio signal reception device 104 to receive extraneous source of sound.In the present embodiment, when audio signal reception device 104 applying bodies 102, by the extraneous source of sound of omni-directional microphone 104b reception from all directions.When audio signal reception device 104 leaves body 102, receive the extraneous source of sound of specific direction (for example direction in vertical source of sound hole) by directional microphone 104b.
Please be simultaneously with reference to Fig. 1～Fig. 3.Communication device 100 is by being installed in the angle detection device (for example magnetic element and Magnetic Induction element) of body 102 and audio signal reception device 104, respond to the turned position of audio signal reception device 104 with respect to body 102, with switch to omni-directional microphone 104b and directional microphone 104b one of them.Magnetic element can have different designs on demand with the position of Magnetic Induction element on communication device 100.
Among the embodiment, when magnetic element 104a was arranged at an end of audio signal reception device 104, Magnetic Induction element 102c also was arranged at corresponding position therein.When audio signal reception device 104 fits in body 102 (with reference to Fig. 2, promptly rotational angle is 0 degree), the magnetic flux of the sensing magnetic element 104a of Magnetic Induction element 102c institute is bigger, and starts omni-directional microphone 104b radio reception.When audio signal reception device 104 be rotated away from body 102 or during perpendicular to body 102 (with reference to Fig. 3, be that rotational angle is about 70 degree to 110 degree), the compare state of Fig. 2 of the magnetic flux of the sensing magnetic element 104a of Magnetic Induction element 102c institute is little, and starts directional microphone 104b radio reception.
In another embodiment, when magnetic element 104d was arranged at an end of audio signal reception device 104 and body 102 pivot joints, Magnetic Induction element 102d also was arranged at corresponding position (articulated section of body 102 and audio signal reception device 104).When audio signal reception device 104 fits in body 102 (with reference to Fig. 2, promptly rotational angle is 0 degree), first magnetic flux of Magnetic Induction element 102d sensing magnetic element 104d, and start omni-directional microphone 104b radio reception.When audio signal reception device 104 be rotated away from body 102 or during perpendicular to body 102 (with reference to Fig. 3, be that rotational angle is about 70 degree to 110 degree), second magnetic flux (being different from first magnetic flux) of the sensing magnetic element 104d of Magnetic Induction element 102d institute, and start directional microphone 104b radio reception.
In another embodiment, magnetic element and the position of Magnetic Induction element in the foregoing description can exchange each other.For example, the position of magnetic element 104d and Magnetic Induction element 102d can exchange each other; The position of magnetic element 104a and Magnetic Induction element 102c can exchange each other, and also attainable cost is invented required purpose.
Please refer to Fig. 4, it is depicted as the calcspar according to a kind of communication device of one embodiment of the invention.When using omni-directional microphone 104b or directional microphone 104b radio reception, its required operator scheme is controlled by processor 110.Processor 110 also is responsible for the interference between inhibition microphone and the loud speaker.As Magnetic Induction element 102c/102d, by measuring the turned position of magnetic element 104a/104d with respect to Magnetic Induction element 102c/102d, make processor 110 switch to two kinds of patterns one of them, and then start omni-directional microphone 104b or directional microphone 104c radio reception.
Though the present invention discloses as above with a preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking the protection range that claims define.
