Abstract

PURPOSE:To provide the device which does not require a power source and enables a user to directly listen to the voice generated by himself with his own ear. CONSTITUTION:A sound collector 1 is mounted at one end of a flexible pipe 2 and a sound radiating part 3 is mounted at the other end. One end of a head band 7 for mounting to the user's head is fixed to the sound radiating part 3. The voice entered into the sound collector 1 is resonated in the space from the inside of the sound collector 1 to the sound radiating part 3. The voice passes the flexible pipe 2 and arrives at the sound radiating part 3 from which the voice is radiated.

Detailed Description of the Invention

INDUSTRIAL APPLICABILITY The present invention can be widely used for speeches, English conversation, karaoke song practice, etc.
The present invention relates to a closed headset.

[0002]

2. Description of the Related Art When a human utters a voice, he or she confirms the voice uttered by the person. There is one that is recognized by the brain as a so-called bone vibration sound in which the vocal cord vibrates the bones of the head, and these two are integrally confirmed by the self. When we hear the voices of others, we only recognize from the eardrum.
This is the reason why one's own voice is recognized in this way, and therefore when one's own voice is recorded on a tape or the like and heard, it may sound different from the voice that one is always aware of.

By the way, how important the auditory sense plays a role in the process of human memorizing words is a matter of words. This is also evidenced by the fact that people living in rural areas have accents or accents unique to that area. That is, in early childhood, words are heard and remembered by the people around them, and if the people around them speak only the correct standard words, the infant will also speak the standard words. The same can be said for foreign languages.

It is clear that hearing plays a major role in humans' memorizing words in this way.
In speech, English conversation, singing practice by karaoke, etc., it is possible to let others hear the trained sound by confirming one's own voice only with air vibration sound, which eliminates the sound caused by bone vibration. Become. For this reason, it is possible to perform developmental training including correction of stuttering, etc., rather than merely performing the above-mentioned education or hobby.

Conventionally, there is no device developed for the purpose of achieving this purpose. If this is done, as described above, the self-recorded voice is listened to later and uttered accordingly. Either record this again to recognize the difference, or use a headset that combines a microphone and headphones with a headband, convert the sound that entered the microphone into an electrical signal and amplify it, then There were two ways to give it to and get the voice again.

[0006]

However, the former one of these methods cannot hear the voice at the same time as the utterance, and the apparatus is large-scale and cannot be easily implemented. There's a problem. on the other hand,
Even in the latter case, there is a problem that even if the apparatus is required and the apparatus is simpler than the former case, it cannot be easily implemented. In addition, they cannot hear their own voices live and hear what is converted into an electrical signal, which is unnatural, and it cannot be carried out without a power supply facility. I have a big problem.

The present invention has been made in view of this point, and an object of the present invention is to provide a hermetically-sealed headset in which the above problems are eliminated.

[0008]

As a means for solving the above-mentioned problems, the present invention provides a sound collector at one end of a pipe and an acoustic radiation portion at the other end, and the acoustic radiation portion is attached to a user's body. The headband for mounting on the head is fixed at one end.

[0009]

According to this structure, the sound generated by the user resonates properly while entering the sound collector and reaching the sound radiating section. Then, the sound is emitted from the sound emitting unit and reaches the eardrum of the user. In this case, of course, the sound through the bone vibration is also recognized, but since the sound from the sound collector is a resonance sound, the level becomes higher than this, and others hear the voice uttered by themselves. You will be able to listen in the same way as you are listening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIG. Reference numeral 1 denotes a sound collector, which is attached to one end of the flexible pipe 2. The structure and characteristics of the sound collector 1 will be described later. An acoustic radiator 3 is attached to the other end of the flexible pipe 2. Sound emission part 3
Is composed of a main body 4 having a hollow inside, and an ear pad 5 attached to the entire outer circumference of the main body 4, and the hollow portion 6 communicates with the inside of the flexible pipe 2. One end of a headband 7 to be worn on the user's head is fixed to the body 4. At the other end of the headband 7, an earpiece 8 having a soft material attached inside is attached.

A sound collector 1 is shown in FIGS. 2 and 3. The sound collector 1 is made of synthetic resin, and is composed of a main body 1a and a mouthpiece 1b detachable from the main body 1 as shown in these drawings. The inside of the mouthpiece 1b is hollow when the mouthpiece 1b is attached. The mouthpiece 1b is provided with a rectangular hole 1c, which is used so that the hole 1c comes to the mouth at the time of mounting.

In this closed type headset thus constructed, the headband 7 is put on the head so that the ear pad 5 of the sound emitting section 3 covers one ear and the ear pad 8 is provided.
Attach to the head by pressing the opposite side of the head.
Then the mouthpiece 1b of the sound collector 1 comes to your mouth, so
When you speak to 1c, this sound resonates in the sound collector 1,
Further, it passes through the flexible pipe 2 and enters the cavity portion 6 of the acoustic radiation portion 3. During this time, the sound is resonated appropriately and is emitted from the acoustic emission unit 3 toward the eardrum.

In the graph shown in FIG. 4, a small speaker is applied to the hole 1c of the mouthpiece 1b of the sound collector 1, the frequency of the sound from this speaker is changed by an oscillator, and the sound is emitted from the sound emitting section. FIG. 6 is a characteristic diagram in which sound is collected by a microphone set in a portion 3; On the other hand, it is a characteristic when the mouthpiece 1b is removed. From this figure,
It can be seen that the mouthpiece 1b is attached to have better characteristics at a frequency around 2 kilohertz which is practically used.

In the embodiment shown and described above,
Although the cavity 6 of the sound emitting portion 3 is illustrated as being considerably larger than the diameter dimension of the flexible pipe 2, the cavity 6
Since the resonance characteristic can be changed depending on the volume of the cavity, considering the relationship with the volume of the sound collector 1 or the flexible pipe 2, etc., the cavity 6 may be filled with an appropriate material depending on the application or preference. Alternatively, structural changes may be made to reduce the volume of this part.

As described above, the hermetically sealed headset according to the present invention is of the air conduction type which guides the sound entering the sound collector 1 from the pipe (flexible pipe 2) to the sound radiating section 3. No power supply is required and you can listen to the sound directly without any conversion. Therefore, it is possible to practice various speeches both indoors and outdoors. Since the mouthpiece 1b can be attached and detached, it can be easily washed when it becomes dirty, and it is also possible to use a personalized one.

[0016]

As described above, the present invention is a hermetically-sealed headset having the above-described structure.
You will be able to practice various speeches and vocalizations.
