Abstract

PURPOSE:To surely input voice to a microphone even when the voice is inputted obliquely to an electronic device by providing a direction wing setting the direction of a sound source to be inputted. CONSTITUTION:Direction wings 20, 21 are provided to an opening section 14. The direction wing 21 is provided to a case 13A so as to be rocked to the left/right around a shaft 22 and the direction of the wing 20 is changed by turning an operation dial 24. Thus, even when a talker (sound source) is located obliquely with respect to a key pad display section 5A, the direction wings 20, 21 are directed in the direction of talker, then the voice of talker is led in the direction of the microphone 9 by the direction wings 20, 21 and surely inputted to the microphone 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Field of Industrial Application) The present invention relates to an improvement in an electronic device having a built-in microphone in its housing.

(Conventional technology) FIG. 3 shows a conventional car telephone device.

This car phone device! 1 consists of an antenna 2, a radio device 3, a speaker box 4, a keypad display section 5, an interface cable 6 that connects the keybat display section 5 and the speaker box 4, an interface cable 7 that connects the speaker box 4 and the wireless@3, etc. It is configured so that you can talk to the other party without holding a handset. That is, the other party's voice is output from the speaker 8 built into the speaker box 4. Further, the user's own voice is input to a microphone 9 built into the key bat display section 5.

As shown in FIG. 4, the key bat display section 5 is provided with a microphone 9, a key bat 10, a display section 11 for displaying various information, etc., and has functions other than the receiving section of a normal telephone. . In addition, the microphone 9 is used to listen to voices other than the speaker.
A device having directivity is used to prevent input of noise, and an opening 14 for inputting voice to the microphone 9 is formed in the housing 13 of the key bat display section 5.

However, since the keypad display section 5 has to be fixed somewhere in the car, it becomes difficult for the speaker to speak from a position facing the microphone 9, which causes a problem in that it is difficult to input voice into the microphone 9. was there. For example, as shown in Fig. 5, the display unit 5 is often fixed to the side of the driver's seat (inside the console, above the dashboard); Even when making a phone call, the speaker inputs voice into the microphone 9 from an oblique direction, making it difficult to reliably input voice into the microphone 9. In particular, this type of microphone 9 has directivity, so this problem is serious.

(Problems to be Solved by the Invention) As described above, with conventional electronic devices, it is difficult to input audio reliably when inputting audio from an oblique direction to the microphone built into the device housing. It is.

The present invention has been made in view of this type of conventional drawback, and is an electronic device that can reliably input audio even when inputting audio from an oblique direction to a microphone built into the housing of a device. The purpose is to provide an i-device.

[Structure of the Invention] (Means for Solving the Problems) In the present invention, in an electronic device having a built-in microphone in a housing, an opening in the housing is provided for inputting audio to the microphone. A direction feather is provided for setting the direction of the sound source to be input to the section.

(Function) Therefore, even when inputting audio to a microphone built in an electronic device from an oblique direction, by directing the direction wing in the direction of the audio, the audio can be reliably input to the microphone.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 and 2.

In the figure, 5A is the key bat display section (
electronic devices). Similar to the conventional example, this key bat display section 5A has a built-in microphone 9 in a housing 13A.
A key bat 10 and the like are provided on the A surface. Also,
An opening 14 for inputting audio to the microphone 9 is formed in the housing 13A at a position facing the microphone 9.

The opening 14 is provided with a directional wing 20.21.

The direction wing 20 is provided on the housing 13A so as to be able to swing left and right about a shaft 22, and by rotating the operation dial 24, the direction of the direction wing 20 changes in the left and right direction. The three direction wings 20 are connected by a connecting rod (not shown), and when the operation dial 24 is rotated, the direction of the three direction wings 20 is changed in conjunction with each other. In addition, the direction feather 21
The housing 1 is arranged so that it can swing up and down about the shaft 25.
3A, and by rotating the operation dial 26, the orientation of the direction wing 21 changes in the vertical direction.

The two direction wings 21 are connected by a connecting rod (not shown), and when the operation dial 26 is rotated, the direction of the two direction wings 21 is changed in conjunction with each other.

With this configuration, the key bat display section 5
Even if the speaker (sound source) is located obliquely with respect to A, as shown in FIG.
1, the speaker's voice (arrow shown in FIG. 2) is guided in the direction of the microphone 9 by the direction feathers 20 and 21,
The input is surely input to the microphone 9.

[Effects of the Invention] As explained above, since the electronic device of the present invention is provided with a direction feather for setting the direction of the sound source to be input,
To reliably input audio to a microphone built into the device even when inputting audio to an electronic device from an oblique direction.
