[0002]

2. Description of the Related Art FIGS. 15, 16 and 17 are perspective views of first, second and third embodiments of a conventional communication device, respectively.

In recent years, communication devices have been rapidly becoming wireless and portable, and accordingly, demands for downsizing have become stronger. However, if the size is reduced, the distance between the receiver and the transmitter becomes narrower, so that the distance between the position of the transmitter and the mouth of the speaker becomes large, and the quality of the transmitted voice deteriorates.

Conventionally, as a countermeasure against this, the transmitter unit is made to project in the direction opposite to the receiver unit as shown in FIG. 15, and the receiver unit and transmitter unit are fixed to a two-part housing as shown in FIG. A sliding structure using the groove 116 for displacing the housing in the direction of the arrow and a folding structure for interposing the hinge portion 125 as shown in FIG.

Further, with the downsizing and portability of communication devices, the environment in which they are used has increased, and there has been a problem that noise and wind noise adversely affect sound quality. Appropriate measures were not taken against this.

[0006]

In the communication device of the type described above, the positions of the transmitter and the speaker cannot always be set to the optimum positions for a call. Therefore, there arises a problem that the sound quality of the talker is deteriorated and that the talker cannot recognize such a sound quality deterioration state. Further, the positional relationship has individual differences due to differences in holding manners and differences in the distance between ears and mouths, which causes different problems depending on the speaker, and there is an increasing need to prevent adverse effects due to noise and the like.

Therefore, an object of the present invention is to make it possible to change the position or direction of the mouthpiece with respect to the position of the earpiece in a small-sized communication device by a simple operation, and the transmitted voice can be optimized according to the speaker. It is an object of the present invention to provide a communication device having a structure capable of detecting and selecting such a position or direction as described above, or having a structure capable of responding to the environment such as noise prevention.

[0008]

According to another aspect of the present invention, there is provided a communication device including a transmitter, a receiver, and a movement or a receiver of the transmitter protruding in a direction opposite to the receiver. In a communication device provided with a movable means for opening and closing by a hinge between the receiver and the receiver, a detector that detects a change in sound pressure of an input sound of the transmitter during movement or opening and closing, and a detector It is characterized in that it has a notifying means for notifying the speaker that the sound pressure has been detected, and a control section for controlling the detecting section and the notifying means.

The communication device according to a second aspect of the invention is a communication device in which a transmitter is provided in the housing, and has a sound collecting means that can project from the surface of the housing around the transmitter.

A communication device according to a third aspect of the invention has the constituent features of the first and second aspects.

According to another aspect of the communication device of the present invention, there is provided a holding portion for holding the transmitter portion, and a swivel shaft for fixing the holding portion and arranged at a lower end portion of the main body case so that both end portions are pivotally supported by the main body case. , And an operation piece that is attached to an end portion of the turning shaft to operate the turning shaft.

It is characterized by having an informing means and a control section for controlling the operating means and the informing means.

[0013]

The communication device of the present invention having various structures described above is
Each has features for creating an optimum transmission state.

To briefly describe these, in one example, the position or direction of the transmitting unit is made movable with respect to the receiving unit, and the input sound of the transmitting unit is detected, notified and controlled so as to be appropriate. Therefore, it is possible to talk at the optimum position according to the speaker.

In another example, since the sound collecting plate has a structure which can be easily projected and restored around the mouthpiece, it is possible to talk without noise by using the sound collecting plate according to the environment.

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

FIG. 1 is a perspective view of an embodiment of a communication device of the present invention, FIG. 2 is a block diagram of sound pressure control of this embodiment, and FIG. 3A shows a detection operation of this embodiment. The flowchart shown is (b), the flowchart showing the maximum sound pressure determination operation of (a), and (c) is a graph showing the principle of (b).

In FIG. 1, a telephone receiver 1, a dial key 3, a transmitter 4 and the like are shown on the telephone body 1, and the transmitter 4 can be projected from the telephone body 1 through a connecting portion 5 in the direction opposite to the receiver. Installed on. When the telephone is not used, the speaker contracts the connecting portion 5 and stores the transmitting portion 4 in the main body 1, and when using the telephone, the connecting portion 5 is extended to bring the transmitting portion 4 close to the mouth for transmission. . In this way, the size can be reduced when carrying or storing.

2 and 3 show the features of this embodiment, as shown in the block diagram of FIG. 2, when the detector 7 detects the maximum sound pressure, the controller 8 drives the reporting means such as the LED 9. . These mechanisms are built into the main body. Figure 3
A process in which the speaker searches for the optimum position of the transmitter 4 will be described with reference to the flowchart of FIG. First, the talker switches to the maximum sound pressure detection mode with the switch key 6. At this time, a method of substituting a combination of a plurality of other keys such as a dial key without separately providing a switching key may be adopted. Next, the transmitter 4 is pulled out from the housed state to the stretched state with one hand, and at the same time, the vocalization operation is performed. When the detection unit 7 detects the maximum sound pressure by the detection method described later, the control unit 8 notifies the speaker by generating a signal by means of the LED 9 which is the notification means. Based on the signal, the transmitter recognizes that the optimum position for obtaining the maximum sound pressure is reached, stops the extension operation of the transmitter unit 4, and exits the maximum sound pressure detection mode by the switching key to end the operation.

Next, the method of detecting the maximum sound pressure will be described with reference to FIG.
A description will be given based on the flowchart of (b). Transmitter 4
1, the displacement from the storage position is M, the time from the start of stretching is T, and the sound pressure L at that time is L. The relationship between the displacement M and time T of the transmitter 4 and the sound pressure L is shown in FIG.
As shown in the graph of (c), it has a peak at a certain point. The detector 7 always detects the sound pressure after a minute interval, for example, ΔT time. The detection unit obtains the amount of change ΔL in sound pressure during ΔT time, determines that the maximum sound pressure has not yet been reached if ΔL has increased, and determines that the maximum sound pressure has been reached when it has decreased.

Next, a second embodiment will be described. FIG. 4 is a flow chart showing the detection operation of the second embodiment, which is provided with a mechanism for storing the maximum sound pressure.

In the communication device shown in FIG. 1, the talker first sets the maximum sound pressure detection mode by the switch key 6, and then pulls out the talker from the housed state to the extended state while speaking. Meanwhile, the detection unit samples the sound pressure and stores the maximum sound pressure.

After that, the speaker continues to speak and returns the transmitting section from the fully extended state to the original stored state. During that time, when the sound pressure reaches the stored maximum value, a signal is generated from the receiver to notify the speaker. From the signal, the talker recognizes that the optimum position where the maximum sound pressure can be obtained is reached and stops the push-back operation of the talker. Then, the operation is terminated by exiting the maximum sound pressure detection mode by the switch key.

Next, a third embodiment will be described. FIG. 5 is a flow chart showing the detection operation of the third embodiment, which is provided with a mechanism for storing the average value of the maximum sound pressure. In the telephone of FIG. 1, first, the speaker sets the maximum sound pressure detection first mode by the switching key, and then, while speaking, pulls out the transmitter from the stored state to the extended state. Meanwhile, the detection unit samples the sound pressure and stores the maximum sound pressure. Next, while continuing to speak, the transmitter is pushed back to the storage position, and the maximum sound pressure is stored during that time. After performing this reciprocating operation a plurality of times, when the talker presses the switch key twice in succession, the mode is switched to the maximum sound pressure detection second mode. The detection unit averages each maximum sound pressure obtained during a plurality of reciprocating operations to obtain an average maximum sound pressure.

After that, when the transmitting section is expanded and contracted while uttering again, the detecting section compares the sampled sound pressure with the average maximum sound pressure, and if the values match, a signal is generated from the receiving section to notify the speaker. . The speaker recognizes from the signal that it has reached the optimum position for obtaining the maximum sound pressure, stops the push-back operation of the transmitter, and uses the switching key to exit the maximum sound pressure detection second mode and end the operation. To do.

Next, a fourth embodiment of the present invention will be described. FIG. 6 is a perspective view of a fourth embodiment of the communication device of the present invention.

In FIG. 6, the telephone body 11 has a structure in which two housings 11a and 11b are connected by a hinge 15. When not in use, the telephone body 11 can be folded in two and made compact, which is convenient for storage and carrying. At the time of use, the housing is opened with the hinge 15 as an axis, and the angles of the two housings 11a and 11b can be freely determined. The earpiece 12, the dial key 13, the switching key 16 for switching the telephone to the mode for searching for the maximum sound pressure, and the LED 19 as the notification means for indicating that the maximum sound pressure has been obtained are provided in the housing 11.
The transmitter 14 is provided in the housing 11b.

In this telephone, the sound pressure changes when the angle α between the housings 11a and 11b is changed, so the user speaks while changing the angle α in order to obtain the maximum sound pressure. This maximum sound pressure detection method can be considered according to the displacement M in the description of the first embodiment by replacing the displacement M with α of the present embodiment, and therefore the description and illustration thereof are omitted. It should be noted that the external structure of this embodiment can be provided with the structures of the detection methods of the second and third embodiments, but these are not listed as the number of embodiments in order to avoid complication, and therefore, Description and illustration are omitted.

Next, a fifth embodiment will be described. 7A is a perspective view of a fifth embodiment in which a U-shaped sound collecting plate 30 capable of protruding from the surface of the main body of the communication device of the present invention is attached, and FIG. 7B is a line A of FIG. FIG.

In FIGS. 8A and 8B, the sound collecting plate 40
Is rotatably attached to the telephone body 31 by a hinge 40a. The structure other than that relating to the sound collecting plate is the same as in the case of the fifth embodiment, and therefore its explanation is omitted.

The state where the sound collecting plate 40 is rotated by the angle β and protrudes from the main body is shown. Sound collection board 4 when carrying
0 is not disturbed because the sound collecting plate 40 is returned to a position aligned with the upper surface and the side surface of the main body when the sound collecting plate 40 is rotated about the hinge 40a from the state shown in the drawing. At the time of use, the sound collecting plate 40 is rotated around the hinge 40a so as to protrude. Since the position of this hinge 40a is near the transmitting surface, there is no risk of interfering with the main body during rotation. And since the periphery of the transmitter is surrounded, the sound quality is improved.

Next, a seventh embodiment will be described. FIG. 9A is a perspective view of a seventh embodiment of the communication device of the present invention having two sound collecting plates 50 that can be folded outward.

As shown in FIG. 9B, the arm 50b extending from the rotary shaft 50a of the sound collecting plate 50 and the locking claw 41e protruding inward from the housing 41b are connected to each other. A spring 50c is attached. A force for causing the sound collecting plate 50 to project in the vertical direction with respect to the main body is applied by the spring 50c as shown in FIGS. 9 (a), 9 (b) and 9 (c). Since the main body is opened as shown in FIG. 9A when the telephone is used, the sound collecting plate is automatically lifted up to surround the transmitter.

When the main body is folded, the tip of the sound collecting plate 50 first comes into contact with the guide groove 41c as shown in FIG. 9 (c). After that, the sound collecting plate rotates along the guide groove, and when the main body is completely folded, it is housed in the recess 41d as shown in FIG. 9D and does not project from the surface of the main body, so that it does not interfere with carrying.
