DESCRIPTION JPS5591289 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view and a front view of a conventional directional microphone, FIG. 2 is a perspective view of the main part of the conventional directional microphone, and FIG. A side view and a front view of a directional microphone according to an embodiment of the present invention, FIG. 4 is a front view of another embodiment, and FIGS. 5 and 6 are connection diagrams of main parts different from each other. 1 ······ Microphone, 3 ········ Light emitting element. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a directional microphone, and enables the distribution of directivity to be visually identified. For example, a dynamic microphone as shown in FIG. 1 or a condenser microphone as shown in FIG. 2 has directivity. However, to the user, how the directivity is distributed spatially b It is the present condition that I do not understand. '= ;:' There is a case where the sensitivity is dropped due to mishandling and handling \, To '-'; When it is uttered from an angle of z 72, the microphone may not be able to perform accurate acoustic-electric conversion. The present invention eliminates such a drawback and will be described with reference to an embodiment shown in FIG. 1 is a microphone main body, 2 is a windshield, and 3 is a light emitting element such as an LED. In this case, light emitting element 3 is viewed from the front of the microphone 0.. Even if the switch 4 is turned on as shown in FIG. 9, the flashing circuit 6 may be turned on when the switch 5 is turned on in addition to the switch 4 turned on as shown in FIG. It may blink. FIG. 4 shows an example in which the light emitting element 3 is provided corresponding to the microphone of FIG. In the embodiment of the configuration described above, the display shape is changed according to the position of the user with respect to the microphone (the position of the user's mouth) by keeping the display shape of the light emitting element 3 corresponding to the directivity of the microphone. Can be seen at Now, when the display of the light emitting element 3 is viewed from the front, if there is 0 at 4 and Pew j nono 3, the user's position with respect to the microphone will be misaligned, so it will be in an elliptical state, eventually disappears. It will 03-05-2019 1 indicate that a normal acoustic-electrical degradation is going to happen. Therefore, while visual indication of directivity can be made by the display of the light emitting element 3, it can also be used as an utterance end command or the like when the light emitting element 3 is in the display state (lights up and is h). , Is advantageous for practical use. As apparent from the abovedescribed embodiments, the present invention has a great practical effect of being able to properly display the direction having the directivity of the microphone. 03-05-2019 2
