Abstract

PURPOSE:To facilitate recording, document examination, etc., during a call and to prevent the transmission of an abnormal sound such as the conversation of an adjacent calling person to a calling party by fitting a receiver and a bone-conduction microphone having excellent sound insulating ability to the tip part of a head band. CONSTITUTION:A receiver 2, in which a small electric voice converter is incorporated, is fitted to one tip side of a head band 1, and a bone-conduction microphone 3 is fitted through a connecting rod 31 having excellent elasticity to the other tip side of the head band 1. This bone-conduction microphone 3 senses the oscillation of a bone accompanying the speaking of a calling person and converts the oscillation into an electric signal when the microphone 3 is brought tightly into contact with facial skin, and since the microphone 3 does not interpose space between the microphone 3 itself and the skin which is interposed for a voice microphone, the microphone 3 itself has the sound insulating ability and never directly senses the voice. Thus, neither of both hands of the calling person is restricted, the abnormal sound such as the conversation of the adjacent calling person is never mixed in the conversation of the calling person, and the accurate call which never gives unpleasant feeling to the calling party can be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone set suitable for business use by a large number of adjacent callers.

[Prior art and its problems]

For example, reception of telephone shipping and mail order, etc.
When a large number of callers are making business calls, such as in a trading room at a securities company, a number of W&telephones are often placed adjacent to each other, and in the case of such business calls. records the address and name of the other party during a call.

By the way, there is a great need to check the materials at hand and answer the phone.By the way, the conventional general telephone device is a handset (handset).
A receiver and a voice microphone are built into each end of the phone, and when the handset is picked up from the phone body, the 1 and -C buttons are automatically connected and the handset can be held with one hand to make a call. Therefore, it is necessary to record a call or look up documents with the other hand, which is extremely difficult and inefficient, and there is a risk of making mistakes. Also,
Because the callers are located next to each other, it is easy for abnormal noises in the room, including the conversation of the person next to them, to enter the voice microphone, and the other party can also hear this noise. Not only is it difficult to hear and uncomfortable, it makes it difficult to communicate accurately, but it also poses a problem in terms of confidentiality.

[Purpose of the invention]

Therefore, the present invention allows the caller to easily record and review documents during the call, and also enables accurate communication without abnormal sounds such as the conversation of the next person being transmitted to the other party. The purpose is to provide telephone equipment.

[Structure of the invention and its effects]

In the telephone device of the present invention, a bone conduction microphone and a receiver are attached to the end of a substantially inverted 0-shaped headband which is worn on the head, and which are connected to the telephone body through a connection cord.
It is characterized by a manual talk button provided on the connection cord or on the phone itself.

That is, when the caller wears the headband on the head, the receiver comes into close contact with the ear, and the bone conduction microphone also comes into close contact with the face 1, for example, the temple.
When the reception bell on the handset rings, you can connect the talk button manually, or when you want to make a call, connect the talk button manually and hit the numeric keypad to be able to talk.
Since both hands of the caller are free, it is easy to record or look up materials during the call. Bone conduction microphones convert the bone vibrations associated with one caller's voice into electrical signals, so the bone conduction microphone converts the vibrations of the bones that accompany one caller's voice into electrical signals.
I) can be communicated accurately without being transmitted to the other party.

〔Example〕

The present invention will be specifically described below based on embodiments shown in the drawings.

In Fig. 1, a headband 1 having a substantially inverted 0 shape is
It is made up of a circular arc member 11 made of a highly elastic material and adjustment members 12 that are extendably attached to both ends of the arc member 11, and can be adjusted according to the size and shape of the head of the person making the call so that it fits closely against the caller's head. There is.

A receiver 2 with a small electric audio transducer built in is attached to one end of the headband 1, and a bone conduction microphone 3 is attached to the other end via a highly elastic connecting rod 31. ing. When this bone conduction microphone 3 is brought into close contact with the skin of the face, it senses the vibrations of the bones associated with the utterances of a caller and converts them into electrical signals. It has sound insulation properties,
Connection cords 4 extend from the receiver 2 and the bone conduction microphone 3, which do not directly detect sound, and become one connection cord 4 at the branch case 41.

A modular plug 42 is attached to the tip of the connection cord 4, and is detachably connected to a plug (not shown) of the telephone main body 6. Near the branch case 41 of the connection cord 4, there is a talk button 5. is provided. This talk button 5 allows you to receive a receipt by pressing the button with your fingertip.
It is a manual type in which the bar 2, the bone conduction microphone 3, and the telephone main body 6 are connected intermittently, and may be directly attached to the FF1 telephone main body 6 like a conventional telephone.

Further, as shown in FIG. 2, the receiver 2 and the bone conduction microphone 3 may be attached to one end of the headband 1, and the pad 8 that contacts the upper part of the ear may be attached to the other end. In this case, the branch case 41 is not required, but the stability when attached to one head is as shown in FIG. Are better.

Thus, one caller always wears the headband 1 on the head, so that the receiver 2 comes into close contact with the ear, and the bone conduction microphone 3 also comes into close contact with the "temple."

Therefore, the bone conduction microphone 3 does not interfere with recording operations, unlike a voice microphone placed at the tip of the mouth, and the receiver 2 does not come into close contact with only one ear. Therefore, the user can freely recognize the reception ring of the telephone main body 6 and have normal conversation when not on a call. When the receiving bell of the telephone body 6 rings, the user manually connects the talk button 5, or when making a call, manually connects the talk button 5 and presses the numeric keypad of the telephone body 6 to make a call. Here, since the caller's hands are not tied during the call, it is easy to record the address, name, etc. of the person on the other end of the call, and to check the materials at hand before responding, which significantly improves efficiency. And since it uses a bone conduction microphone 3 with excellent sound insulation properties without directly reacting to the voice, there is no interference from abnormal sounds such as the conversation of the person next to you.
Since it is possible to make accurate calls without causing any discomfort to the other party, the telephone is extremely suitable for use by a large number of adjacent callers for business purposes.

〔Effect of the invention〕

As explained above, the telephone of the present invention has a receiver and a bone conduction microphone with excellent sound insulation attached to the end of the headband, so that the caller can perform tasks such as recording and researching materials during the call. It is possible to easily carry out this process, and to provide a telephone set that allows accurate communication without transmitting abnormal sounds such as the conversation of a neighboring person to the other party.
