Description

  The present invention relates to a method for arranging microphones, speakers, and switches of a hands-free device for a functional and practical mobile phone, and a volume of the speakers.

  With the widespread use of mobile phones, it has become an urgent task to develop a mechanism that allows users to talk when they are busy when driving a car, driving a motorcycle, or at a construction site.

  As a known technique, there is a technique in which an earphone is placed on an ear and a switch and a microphone are arranged in the middle of a cable extending from the earphone so that both hands are free. However, it is inconvenient in daily life to wait with an earphone for a mobile phone call that you do not know when it will come. Therefore, it has not been popularized.

  In addition, methods that do not use earphones have not been put into practical use other than fixed telephones and telephones built into automobiles. It was thought that there was an essential difference in usage between the technology for listening to small sounds with earphones and the technology for listening to loudspeakers with loud sounds.

  However, the practical application of the technology to listen to the sound that should be heard through the speakers with headphones or earphones (earphone type stereo) has shown that the two can actually be used with each other.

  And the reverse use, that is, the technology of listening to the sound to be heard with a headphone or earphone with a speaker has not been put into practical use.

  By the way, regarding the hands-free invention of the mobile phone, the past inventions include a hands-free device for a mobile phone (Japanese Patent Laid-Open No. 2000-138744) (1), a hands-free transmission / reception of a mobile phone, a method and a device for use thereof 2000-59859) (2), a helmet capable of receiving and transmitting a mobile phone or the like while wearing a helmet (Japanese Patent Laid-Open No. 2000-355821) (3), a built-in helmet type handless telephone (utility model registration No. 3081735) (4) ), Mobile phone hands-free devices (Japanese Patent Laid-Open No. 2002-16690) (5).

  In (1) and (5), the switch is automatically turned on when an incoming call is received. (2) uses a car stereo speaker by connecting a mobile phone to the car's electrical system. (3) is to put headphones in the helmet. (4) is to incorporate a mobile phone in the helmet.

  As for (1) and (5), turning on the switch is not so burdensome even if the car is driven. When actually turning the direction indicator or changing gears, the driver releases one hand. If there is a switch at a certain point and the switch is turned on with a simple operation, this can be done manually.

  (2) The idea of listening to the sound that should be heard with the earphone is similar to the present invention, but the present invention is based on the idea that the sound is totally increased by the speaker and the sound is made to flow throughout the place. However, there is one that seeks a sound volume similar to that heard with an earphone while listening to the speaker without spreading the sound over the whole place, and the idea is different from the present invention in this respect. In other words, the invention of (2) attempts to realize hands-free by demonstrating the function of the speaker as a speaker, whereas the present invention seeks to pursue the function of the earphone while using the speaker. The idea is different. The invention (2) can only be used in a car.

  Although (3) to (4) may be effective when a motorcycle is operated, it does not solve the troublesomeness of wearing an earphone or a headphone on the ear.

Problems to be solved by the invention

  In the end, people want to receive their calls with their hands free when they receive a call while sending a normal life. If you can do this, when you are driving a car, when you are driving a motorcycle, when you want to take notes while listening to the phone, because you have a blueprint or map in your construction site, your hands are blocked It is very effective when you are in it. In other words, it is an object of the present invention how to simultaneously achieve the desire to lead everyday life and the conflicting desire to call without carrying the mobile phone when the mobile phone is called.

  Also, telephone calls have a privacy aspect, and the caller does not want the conversation to be heard by a third party. Therefore, if it is possible that only the person who wants to hear it is the true intention of the caller and that is disclosed to all who are present, the caller will not want to use it. Such sounds are also annoying for third parties.

  Therefore,

as well as

There are the following three conditions for solving this problem. When receiving a mobile phone hands-free (1) Ears are not blocked by headphones, earphones, etc. (Let's live a normal life.) (2) Installation of the equipment does not take time and is easy. (3) The sound that can be heard by the mobile phone is such that it can be heard by the caller, and even if it can be heard by a third party, it should not be loud enough for the third party to feel noise.

Means for solving the problem

  Therefore, according to the present invention, since the earphone is a cause of isolation from daily life or a cause of impairing safe driving during driving, the earphone portion is first removed and this is used as an external speaker.

  And it decided to detect a sound by installing this near the ear.

  The speaker, microphone, and switch were installed concentrically. This is because the circle is the largest form of freedom. Hands are freed by wrapping the loop around the head, arm, and belly.

  And the speaker needs to be near the ear. This is because by placing a speaker near the caller's ear and playing a sound that can be heard by the caller, harmony between the caller's privacy and the inconvenience of surrounding third parties can be achieved. If so, this ring needs to be wrapped around the head.

  Therefore, microphones, switches, and speakers are arranged concentrically, and these devices are placed in a single ring and installed in a headband, hat, helmet, or the like.

  The cable that connects them is housed in a headband, belt, hat, helmet, etc., so that the cable to the earphone terminal extending from here to the mobile phone can also be housed in this. This is because a mobile phone can be used as a single unit, and a headband, belt, hat, helmet, etc. can also be used as a single unit.

  How about installing such a device, for example, just pull the cable out of the hat and connect it to the mobile phone. All you have to do is put on a hat and the impact on your daily life will be minimized.

    Technical considerations are the speaker form and volume. A ring is put on the head and the speaker is just above the ear. If it is in that position, what form is most desirable, what level is good, how to let the sound escape from the belt, hat, helmet etc. that is in the shape of a ring, It must be considered from the viewpoint of the profitability of the privacy of the caller and the prevention of nuisance to surrounding third parties.

The invention's effect

  In this way, the mobile phone can be used with both hands free, just by turning on the switch while driving, walking, or when both hands are occupied.

  If you are alone while driving, there will be no inconvenience to third parties, and even if there are passengers, if you are eager to know, the contents of the call will be known to some extent or the call will be Even if you can hear it, it's acceptable to both, but it doesn't cause privacy issues or inconvenience to third parties.

  If you're walking, you should move as quickly as possible, stop where no one else is, and consider talking.

  In addition, the mobile phone can be taken out while driving a car, visually switched on, and the situation of driving operation with the mobile phone attached to the ear while releasing one hand is eliminated, so that the user can talk safely. . In addition, since it is possible to work with both hands free at the construction site, the work efficiency is improved, and it is not necessary to change the things that you have with the mobile phone, which contributes to safety.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  When driving a car or when it is predicted that both hands will be blocked, pull the cable (6) from the cable storage (5) of the belt (1) and put it into the earphone jack (9) of the mobile phone (7). Insert the tip and wear a belt, hat, helmet, etc.

  When a call comes in, press the switch (3) concentrically connected by a cable.

  Now the phone is connected and you can talk. The other party's voice is heard through a speaker (4) connected by a concentric cable.

  This voice is transmitted to the other party from the microphone (2) installed on the concentric forehead.

  When the call is complete, press the switch (3) to hang up.

Attach an adjustment band (8) of the belt size to fit the head when worn.
