Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hands-free set type telephone system using a general-purpose portable telephone, and is compact and convenient for installation, which can be widely used for in-vehicle use, home use, and the like. The present invention relates to a telephone system using a telephone.

[0002]

2. Description of the Related Art In recent years, automobile telephones have become extremely popular, and in addition to conventional handset telephones, hands-free telephones have been developed in order to avoid one-handed driving during the operation of the handset.

[0003] This type of hands-free telephone set is
A microphone for transmission is installed in, for example, a sun visor section, and an ON / OFF switch for transmission and reception is installed in, for example, a steering wheel section.
Since the dedicated speaker or the in-vehicle audio speaker is also used, the driver can talk without releasing the hand from the steering wheel.

[0004] In this case, since a car-dedicated telephone cannot be used once leaving the car, a conventional general-purpose portable telephone is configured to be connectable to a hands-free set telephone device. At that time, a mobile phone that can be used has been proposed.

[0005] Such a hands-free set type mobile phone system is configured such that a hands-free set housing is mounted in a seat side box of a center console or on a lid of the seat side box, and a mobile phone is set therein. Have been.

[0006]

However, in the conventional hands-free set car telephone system, there are (1) restrictions on the installation location, and (2) a harness or hands-free set for connecting the hands-free set to a vehicle power supply. There have been various problems such as the need for a harness for connecting to a mobile phone, and (3) a complicated structure and high cost.

That is, in the conventional device, the hands-free set is stored in the seat side box of the center console or tied to the lid, so that the seat side box cannot be used, and the shape of the seat side box differs depending on the vehicle type. Therefore, it is difficult to firmly fix it, or a special part for mounting is required separately, which causes an increase in cost.

Further, when the hands-free set is mounted on the lid of the seat side box, the signal wiring harness is exposed, and there is a problem that the interior is not organized and the appearance is poor. Since the user needs to operate the device facing sideways, the operability is poor.

[0009] Therefore, the present inventors have made the housing of the hands-free telephone device into a general-purpose can shape, put a portable telephone therein, and adopted a battery as a driving power source, so that it was compact and convenient for installation. An inexpensive hands-free set and a telephone system using it have been developed.

However, when the operation buttons of the mobile phone are pressed or the display panel is viewed, it is necessary to take the mobile phone out of the can housing one by one, and this operation requires the use of both hands. It turned out to be bad.

The present invention has been made in view of such problems, and has as its object to provide a hands-free telephone device with improved operability of a portable telephone and a telephone system using the same.

[0012]

In order to achieve the above-mentioned object, a hands-free telephone device according to the present invention comprises a general-purpose can-shaped housing provided with a microphone, a speaker, and a battery power supply. In the device, an opening for operating the mobile phone is formed on a side surface of the housing, and the microphone and the speaker are provided below the opening on a side surface of the housing. I do.

In the hands-free telephone device of the present invention, since an opening is formed on the side surface of the housing, when the operation button of the mobile phone is pressed or the display panel is viewed, the operation or visual recognition is performed through the opening. can do. Further, since it is sufficient to simply form the opening, it is very advantageous in terms of cost.

In the hands-free telephone device of the present invention,
Since the microphone and the speaker are provided below the opening on the side surface of the housing, the microphone is installed with the opening facing forward even when operating a mobile phone or when making a call. It can be used as it is without rotating the housing.

Since a general-purpose can shape is used, the layout of components such as a microphone and a speaker must be performed efficiently. In this hands-free telephone device, the space below the accommodating portion of the portable telephone is used. .

In addition to the above features, the hands-free telephone device of the present invention has the following features. That is, in the hands-free telephone device of the present invention, since its housing is formed in a general-purpose can shape, installation is extremely convenient.
For example, when used for in-vehicle use, it can be directly installed on a cup holder mounted on an automobile, and when used for home use, it can be installed on a table or other place as it is.

In the case where the hands-free telephone device of the present invention is applied to a vehicle, the cup holder in which the casing having a general-purpose can shape is installed is not only one that is previously mounted on a car but also one that is retrofitted. included. The mounting position of the cup holder is not particularly limited, and may be anywhere such as a center console, a door side, or an upper surface of an instrument panel.

In the hands-free telephone device of the present invention, since the microphone as the input unit of the hands-free set and the speaker as the output unit are provided in the can-shaped housing, the microphone, the speaker, and the control circuit board are provided. The harness for connecting to the vehicle is not exposed indoors.

Further, in the hands-free telephone device of the present invention, the power source of the various electronic components provided on the control circuit board is a battery, and the battery power source is provided in the can-shaped casing. The harness for connecting to the vehicle is not exposed to the room, and can be moved freely anywhere.

In this case, the battery may be a secondary battery. In addition, it is preferable that a terminal for charging the secondary battery be provided by a vehicle power supply when applied for in-vehicle use and a household outlet when applied for home use. By doing so, the vehicle-mounted battery power can be supplied from the cigarette terminal or the like, or the household power can be supplied from the outlet, so that the battery can be charged as it is even if the battery capacity is reduced by prolonged use, which is more convenient than a dry battery. . In the hands-free telephone device of the present invention, an on / off switch for battery power may be provided.

In the hands-free telephone device of the present invention,
It is preferable that the microphone and the speaker are connected to an input / output terminal of a built-in microphone and a built-in speaker of the mobile phone via a harness. By providing only a microphone and a speaker in a hands-free telephone device, that is, by using a portable telephone as a transmission / reception circuit, a compact and inexpensive hands-free telephone device can be provided.

In the hands-free telephone device of the present invention,
It is preferable that a control circuit board that controls transmission and reception of audio signals between the microphone and the speaker and the input / output terminals of the built-in microphone and the built-in speaker of the mobile phone is provided in the can-shaped housing. By providing the control circuit board in the housing, the connection harness for connecting the microphone and the speaker is not exposed to the room.

In this case, it is preferable to provide the control circuit board here by utilizing the space at the bottom in the housing.

The above object can also be achieved by a telephone system having the above-described hands-free telephone device and a portable telephone.
