Description

  The present invention presses the vibration transmitting unit against the external throat of the human body, outputs the selected audio vibration and vibrates the vocal cord through the human body skin from the outside of the human body as an exemplary audio vibration, and the vocal cord unit vibrates by itself. The vocal cord part itself corrects the vibration so that the generated voice vibration is synchronized with the exemplary voice vibration, thereby improving the sound quality of the human body sound generation sound, expanding the high / low pitch of the scale, stabilizing the pitch, etc. The present invention relates to a voice correction device that can be used for training of vocal cord reproduction and that can also be used for vocal training after vocal cord surgery.

Conventional utterance training plays back the voice recorded on the recording device as the goal of the training outcome, listens to the model voice of the training instructor, recognizes it as the goal of his / her achievement, and then plays the voice in line with his / her recognition. Speaking is done.
In this way, in order to approach the model voice, the difference between the target voice recognized by itself and the voice actually spoken is recorded and played back by the recording device, and the reproduced voice is heard by one's ear. Compared to the speech recognized by the person in his / her brain, he repeatedly trained to approach the target speech, and his goal was to reach the target by recognizing his own listening accuracy and recognition accuracy errors in the brain. Repeated vocal training was necessary.

  However, such vocalization training is a repetitive process where there is no external action on the vocal cord part itself, only listening to its own voice, comparing and correcting in the brain, re-recognizing it and vibrating the vocal cords again, By giving a typical vibration to the vocal cords from outside the human body and synchronizing the voice vibrations uttered by the vocal cords with this vibration, the vocal cord vibrations induced by the recognition in the brain are induced by the typical vibrations, and their vocal sounds The vibration of the vocal cord part is brought close to a model vibration, and the voice thus obtained and the action of the vocal cord part at this time are memorized in the brain, and when the next voice is spoken, There is no utterance training to utter using the function of the vocal cord at this time.

  The present invention is an apparatus for applying a typical vibration to the vocal cord part from the outside of the human body as a voice correction and utterance training device, and at least an oscillation for driving the output part to act on the vocal cord part itself from the outside A sound correction device characterized in that it is configured to include a display unit, an amplification unit, and a display unit, and further, a sound collection unit, a recording unit, A speech correction apparatus that can include a playback unit.

  The output unit includes a sound vibration generating unit, a vibration transmitting unit, and an elastic film between the sound vibration generating unit and the vibration transmitting unit, and an air chamber is provided between the elastic film and the sound vibration generating unit. An audio correction device in which a vibration transmission unit including at least a cushion member is provided on the opposite side of the audio vibration generation unit across an elastic membrane and the output unit is configured using the vibration transmission unit as the vibration transmission unit, and at least the cushion member includes Can be installed, removed and replaced.

The body is equipped with means for wearing, and the shape of the bottom surface is set to a shape that avoids interference with the shoulder ribs when worn on the body, and the speaker is elastically supported by the corrugated plate-like part. The corrugated plate-like part bends and vibrates in conjunction with the vibration of the speaker, and the sound pressure is emitted from the speaker, and the sound pressure becomes a pressure wave directly on the bottom surface of the back half case. Propagated or air vibration is first generated in the sound pressure generating chamber. This air vibration is transmitted to the back space through the through hole (or slit or the like) of the defining plate, and as a result, the air vibration is generated in the entire internal space of the container body. Coupled with this, due to the vibration of the cone paper of the speaker, the speaker itself vibrates while flexing and deforming the corrugated portion of the defining plate.

  Mounted on a human body mounting means comprising storage means for storing electrical signals, reproduction means, separation means, a plurality of amplification means, and conversion means for converting each electrical signal into mechanical vibration. Sensible vibration generator.

The problem of Patent Document 1 to be solved is that the two hermetic chambers 5 and 6 are united by air through the vibration plate and vibrate so that the vibration energy vibrates the entire outside of the sealed container. In a specific direction, for example, when the airtight chamber 5 requires air pressure to vibrate as vibration energy, air pressure as air vibration energy due to the vibration of cone paper is transferred from the airtight chamber 5 to the airtight chamber 6, which is useless or obstructive. This is to generate vibration energy. Also, since the outer edge portion of the diaphragm is fixed in the hermetic container via a shock absorbing material that absorbs vibration, the vibration energy in a specific direction, for example, the airtight chamber 5 as described above. As the air pressure as air vibration energy due to the vibration of the cone paper increases in the airtight chamber 5, the cone paper is pushed by the reaction and Since the air itself moves to the airtight chamber 6 side, the air pressure in the airtight chamber 5 decreases, and the air pressure as air vibration energy due to the vibration of the cone paper cannot be obtained efficiently, and the speaker itself moves. Therefore, accuracy cannot be expected in the vibration waveform due to the vibration of cone paper.
Therefore, a structure that efficiently transmits air pressure as air vibration energy due to the vibration of the cone paper of the speaker in one direction is required.

The problem of Patent Document 2 to be solved is that the speaker is elastically instructed by the corrugated plate portion, and the corrugated plate portion flexes and vibrates in conjunction with the vibration of the speaker. While sound pressure is emitted from the speaker, this sound pressure is transmitted as a pressure wave directly to the bottom surface of the back half case, or first, the air vibration that causes air vibration in the sound pressure generation chamber is Propagated to the back space, and as a result, air vibrations occur in the entire internal space of the container body.
Similarly to Patent Document 1, when sound pressure is generated from a speaker, the speaker itself moves due to the reaction, and the sound pressure of the speaker cannot be obtained efficiently in one direction. The energy used to vibrate the entire interior space of the container body is used. Similarly, the sound pressure of the speaker cannot be obtained efficiently in one direction, and the accuracy of the vibration waveform due to the vibration of the cone paper cannot be expected.

  The problem of Patent Document 3 to be solved is that the structure of the vibrating body is “for example, with the voice coil as a fixed side” and “the surface of each diaphragm is covered with a cushion so as not to directly contact the human body”.
