ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an ear mike phone as a hand-free device, which performs as a mike and a speaker by being connected to a hand phone, so as to contribute to a safe driving during a driving of a car. Particularly the present invention relates to an ear mike phone as a hand-free device, in which switches and the like for supplying a power to the mike and the speaker are efficient, and therefore, the driver's driving attention can be prevented from being dissipated.
2. Description of the prior art
Generally, a car hand phone is fixedly installed within the car by using a support. Or a mike and a speaker are separately installed and connected through lines to the hand phone.
A hand phone apparatus related to this technique is illustrated in FIG.
1
. As shown in
FIG. 1
, ends of a cable
53
are connected to a plug terminal
51
and to a main body part
52
, and the cable
53
is connected through a switch
54
. The main body part
52
is connected to a connecting rod
55
, and the end of the connecting rod
55
is connected to a mike
56
. Thus there is formed a mike phone
60
on which a speaker
57
is formed on the main body part
52
. The mike phone
60
is inserted into the ear of the user, and therefore, telephone talks can be carried out at a distance from the hand phone.
In the hand phone as described above, the plug terminal
51
which is connected to the cable
53
is connected to the hand phone. Then if the switch
54
of the cable
53
is turned on, the voices from the hand phone are transmitted through the cable
53
to the speaker
57
which is installed on the main body part
52
. Under this condition, the voices of the user are transmitted through the mike
56
to the hand phone, so that the other party can hear the user's voices.
The operations of the mike
56
and the speaker
57
of the mike phone
60
are carried out by turning on or off the switch
54
of the cable
53
. The user inserts the speaker
57
of the main body part
52
into the ear of the user, and uses it by manipulating the switch
54
of the cable
53
.
In the hand phone apparatus as described above, however, the user inserts the speaker
57
into the ear stably, and the switch
54
of the cable
53
is manipulated, thereby activating the mike phone
60
. Thus the user's action for groping for the switch
54
and activating the switch
54
is considerably troublesome. During this action, the driver's attention is dissipated, and therefore, an accident might occur.
Further, when manipulating the switch
54
, the cable
53
is oscillated, and therefore, the speaker
57
of the main body part
52
which has been stably inserted into the ear may depart and drop from the ear.
Meanwhile, another ear mike phone is disclosed in Japanese Patent Application Laid-open No. Hei-10-164682.
This ear mike phone is illustrated in FIG.
2
. As shown in
FIG. 2
, the earphone-microphone
69
includes: an earphone part
63
to be inserted into an ear; a microphone part
65
connected through a tubular connecting part
64
to the earphone part
63
; and a cord
67
extending from the microphone part
65
, with a plug
66
being installed to the leading end of the cord
67
. The microphone part
65
is facing in the direction of the sound transmitting face of the earphone part
63
, and the portion contacting to the cheek is flat.
In this ear mike phone apparatus, the plug
66
of the cord
67
is connected to the hand phone, and the earphone part
63
is stably inserted into the ear, thereby supporting the earphone-microphone
69
. Thus the user's voices are transmitted through the microphone part
65
in which the portion contacting to the cheek is flat. Meanwhile, the other party's voices can be heard through the earphone part
63
.
However, the earphone-microphone
69
can be activated only by inserting the plug
66
into the hand phone. Therefore, the concentration of the driving attention can be dissipated, and furthermore, the time for inserting the earphone-microphone
69
is considerably long. Therefore, a considerable trouble is encountered in using the earphone-microphone
69
.
SUMMARY OF THE INVENTION
The present invention is intended to overcome the above described disadvantages of the conventional techniques.
Therefore it is an object of the present invention to provide an ear mike phone in which an actuation knob for the switch is installed on the main body part so as to make it easy to carry out the switching manipulations, thereby preventing the dispersion of the driving attention, and preventing a possible accident.
It is another object of the present invention to provide an ear mike phone in which the main body part is firmly supported within the ear to prevent a departure of the main body part so as to upgrade the reliability, and the actuation of the switch is done quickly and accurately.
It is still another object of the present invention to provide an ear mike phone in which switching manipulations for connecting and disconnecting the power from the mike and the speaker are eliminated.
In achieving the above objects, the ear mike phone according to the present invention includes: a main body part connected to a mike and a speaker, and connected to a cable to be connected to a hand phone; a switch installed on an adjustment board of the main body part, for activating the mike and the speaker; and a switch control part with its one side contacting to the switch, and with its another side projecting from a side of the main body part.
In another aspect of the present invention, the ear mike phone according to the present invention includes: a main body part connected to a mike, and connected to a cable to be connected to a hand phone; a switch installed on an adjustment board of the main body part, for activating the mike and a speaker; and a switch control part movably inserted into a side of the main body part to secure the speaker (connected to the cable), with its end portion activating the switch during its motion.
In still another aspect of the present invention, the ear mike phone according to the present invention includes: a main body part connected to a mike and a speaker, and connected to a cable to be connected to a hand phone; a plurality of contact electrodes installed in the main body part, for activating the mike and the speaker; and a switch control part with the speaker installed thereon (the speaker being connected to the cable), being elastically supported by being inserted around the speaker in a plural number, and its inserting ends being connected to the contact electrodes.
