Description

[Detailed Description of the Invention] At the same time, using a vibration pickup that picks up bone conduction audio signals (vibrations) on the transmission thread and converts them into t-signs,
This invention relates to an improvement of a one-ear transmitting/receiving type ear microphone that enables transmitting and receiving with only one ear. More specifically, it is possible to prevent the vibration pickup of the transmission system from picking up code noise, and even if the wearer (transmitter/receiver) performs vigorous physical exercise such as doing strenuous work. This invention relates to a one-ear transmitting/receiving type ear microphone that prevents the ear microphone from falling out of the ear canal.

The technology for transmitting and receiving calls with one ear is: - A technology in which both the transmitting and receiving systems use a sound pressure system, - A technology in which both internal systems are vibration type, and - A vibration pickup type in the transmitting system, and a sound pressure speaker. 2) conversely, a technique that combines a sound pressure transmitting system and a vibration wave receiving system is known.

The inventors of the present invention have conducted research on the technologies described in (1) to (3) above, and have found that the removal of external noise when used in intensely noisy environments, the prevention of howling in platforms that employ a simultaneous transmitting and receiving communication method, the manufacturing cost, and the use of I learned that the technique described in (2) above is also advantageous for moths from the viewpoint of interposing the senses. Even with this technology (2), I learned that it is more advantageous from various points of view to place the i-type human beaker outside the earpiece than to place it inside the earpiece with a built-in vibration pickup. That is, a sound pressure speaker is arranged separately from the earpiece having a receiving system sound guide section and a transmitting system vibration pickup, and the sound output of the cough sound pressure speaker is transmitted through the sound pipe to the I.
I learned about the fist that is best for guiding the sound into the four capitals of the II earpiece. Also, regarding the transmission system, I learned that it is advantageous to lead the electrical output of the vibration pickup to the outside of the earpiece via a lead wire and manually input it to the transmitter.

In other words, a method is known in which an ultra-compact transmitter is built into the earpiece and the electrical output of the vibration pink-up is sent directly from the earpiece to the transmitting and receiving partner. I learned that fists have drawbacks such as worsening the feeling of wearing due to .

Based on the above findings, the Ministry of the Invention, etc. has determined that the acoustic output of a sound pressure-reducing speaker installed outside the earpiece is integrated into an earpiece that has a receiving system sound guiding section and a transmitting system vibration pickup.
II. A flexible sound pipe that integrates a flexible sound pipe that leads to the sound guide section and a flexible lead wire that leads the electrical output of the vibration pickup to a transmitter provided outside the earpiece. We prototyped a one-ear microphone that is connected as a cord and used it for transmission and reception.As a result, the flexible hood protruded from the earpiece attached to the ear canal and hung down, making it difficult for the wearer to use it. When the flexible cord sways with every movement of the body,
The earpiece is pulled and moved by the flexible cord, which not only fluctuates the pickup efficiency of bone-conducted audio signals transmitted to the wall of the ear canal, but also, in extreme cases, causes the earpiece to fall out of the ear canal.

Conventional techniques for solving the above-mentioned drawbacks include (0) a technique for clipping a part of the cord to the earlobe using a clip;
) Technique to attach part of the cord to the headband, (3) Technique to attach part of the cord to the ear hook attached to the back of the ear shell, ■ Technique to attach part of the cord to the eye-challenging string, (5
) A known technique is to attach a part of the cord to a ring-shaped member that fits into the root of the ear shell.

However, the technique marked II causes earlobe pain if the dangling cord is pulled too hard, and the technique (2) above prevents the helmet from being attached because the headband becomes an obstacle. It cannot be used in fields where it is compulsory for workers to wear helmets, such as workers at field or coal mining sites, and the technology described in (2) above has the risk of the ear hooks falling off due to intense physical exertion. The technology in 4) cannot be used by people who do not wear glasses, and the technology in (5) above allows the ear shell and its base to vary in shape and size depending on race, gender, age, etc. There are individual differences, and the ring-shaped member lacks versatility, so the member may move or fall off depending on the person.For this reason, there is a technique that combines it with a rubber band that is tightened around the head. , it is difficult to wear it for a long period of time.Furthermore, as can be said for all of the techniques listed in (5) above, the appearance and appearance when worn were poor, and the feeling of wearing was not excellent.

SUMMARY OF THE INVENTION Therefore, the first object of the present invention is to provide a one-ear transmitting/receiving ear microphone using a sound pressure speaker in the receiving system and a vibration pickup in the transmitting system, in which a flexible lead wire and a sound conduit are connected. The integrated flexible cord is
To provide a technology that prevents an earpiece fitted into an ear canal from falling off even if the earpiece is swayed or pulled by the wearer's body movements, and can prevent cord noise from being picked up. .

The second object of the present invention is to prevent the earpiece from falling off and to prevent cord noise from being picked up even though the shape and size of the ear shell and its base vary depending on race, gender, age, etc. 1. A piece that can be securely attached to the ear shell so as to achieve the following.] 4. To provide a transmitting/receiving type ear microphone ρ phone.

A third object of the present invention is to provide a piece j4. which is easy to install and remove, and which has an excellent appearance and feeling of wearing. An object of the present invention is to provide a transmitting/receiving type ear microphone p-phone.

A fourth object of the present invention is to prevent the receiving system sound conduit constituting a part of the flexible cord from bending, and thus to improve the acoustic output of the sound pressure type speaker disposed outside the earpiece. To provide a one-ear transmitting/receiving type ear microphone which can be reliably introduced into the external auditory canal through an earpiece.

The above-mentioned aspects of the present invention are, in the above-mentioned one-ear transmitting/receiving ear microphone, which uses a combination of a sound pressure type receiving system and a vibration type transmitting system to transmit and receive calls using only one ear, , it is movably stopped by an elastic member arranged so as to extend from the vicinity of the ear canal to the vicinity of the earlobe. A single-ear transmitting/receiving ear microphone pI: 1 in which the flexible cord part between 1l and 9T and the elastic member form a loop that can be hooked onto the root of the ear shell and tightened. Hereinafter, the present invention will be described based on the illustrated embodiment.

First, a typical example of a single-ear transmitting/receiving ear microphone used in the present invention will be discussed. As shown in FIGS. 1 and 2, the earpiece consists of an adapter part IA that is inserted into the ear canal, and an outer case IB that is inserted into the entrance of the ear canal. A mounting part 3 of a female thread provided at the rear end of the front 11IA is removably attached to a mounting part 2 of a male thread etc. provided on the front part of the outer case IB. Hei case 4 is built in (% from the JIJ side of case 4 inside the box)
The hollow case 5 is made to protrude toward the inner hollow part gx (8m means the inner hollow part g of the 7-legged pig member I) of the object 8+82 described in JIII.
A sound hole 8 is provided on the front surface of the adapter part IA in which a vibration pickup 7 such as a piezoelectric element supported by a support 6 is built in. inner wall and 1

g11t, and is acoustically connected to the hollow g formed between the inner wall of the outer case IB and the outer wall of the west case 4. A flexible sound conduit 10 (a tube-shaped tube made of an elastic material such as soft natural or synthetic rubber or soft synthetic resin) is connected from the bottom of the outer case 1B to the sound pressure type speaker 9. It is incorporated into the outer case 13, and the 10 sound outlets of the sound pipe 10 are inserted into the Mav'
l! ! It is aimed at tl1g. On the other hand, the lead wire 11 of the vibration pickup 7 marked # (the one shown in the figure is a piezoelectric element and is installed so that its operating direction is not vertical but horizontal) is also connected from the bottom of the outer case IB. It is led out of the case. In other words, the negative extreme - FMIIA

The sound conduit 10 and the lead wire 11 led out of the case are joined in parallel and integrated to form integrated flexible cords 10 and 11. In addition,
The technology for integrating both 10 and 11 is not limited to this, but the sound pipe 1
Other methods may be adopted, such as including the lead wire 11 in the flexible cord 11 of the present invention, as shown in FIGS. Elastic member 1 arranged to extend from the vicinity of the population 14 to the vicinity of the earlobe 15
It is movably stopped by 6.

That is, the elastic member 16 is constructed by attaching duplexes 16B-160, which shoulder the insertion holes, to both ends of the elastic wire portion 16A, and the flexible cords 10 and 11 are attached to the tubes 16B-160. The three locations are loosely scaled to five, which are movable. IIJ elastic wire portion 16A
is made of an elastic material such as soft natural or synthetic rubber or soft synthetic resin, but may be structurally elastic like a so-called helical spring. Although the tubes 16B-160 are made of a material with a high coefficient of friction such as rubber, they may be made of a material having a high frictional property by, for example, making the inner wall 1thi.

As shown in FIG. 3, in the flexible cord 1oφ11 of the present invention, the flexible cord portion between the two parts stopped by the chain 161j-16C is attached to the ear shell 17 together with the elastic wire portion 1aA. The bolt is hung on the root part and tightened, so when using it, just do the following. First, the adapter part IA is inserted into the ear canal, and the outer case IB is fitted into the ear shell 17 at the entrance of the ear canal.

After the sender/receiver has finished installing the earpiece l of the ear microphone in the ear canal as described above, the flexible cord 10 hangs down below the part stopped by the tube 160 when the sender/receiver engages in strenuous work or the like. - Even if part 11 is pulled, the tension is applied to the upper end of the root part of the ear shell, so the looped cords 10 and 11 will not come off from the ear shell 17. Therefore, the earpiece l does not become detached from the ear canal. Further, even if mechanical vibration is applied to the hanging cords 1° and 11, the mechanical vibration is absorbed by the ear shell 17 and the elastic member 16. Therefore, it is possible to prevent the IIJ vibration from propagating to the earpiece l, thereby preventing the vibrating bump 7 from picking up so-called cord noise. Furthermore, since the flexible cord 10φ11 is looped around the ear shell 17,
Even if the cord part that is bent downward is strongly pulled, the Vr conduit 10 will not bend or become blocked, so defects such as interruption of received sound will not occur.

In addition, when removing the ear microphone according to the present invention, be sure to widen the loop formed by the flexible cord lOφ11.
Then, slide up the tube 16 (41 minutes of hood 11 and remove it from Jil and eIL17).
