The present invention provides a bone conduction speaker capable of recognizing and recognizing an audio signal through vibration of a vibrator on a bone of a human head.
In any case, the implantable type requires surgery and has this drawback when it is time-consuming and causes excessive damage to the body.
The bone-conduction earphone type also has the drawback of becoming tired if used for a long time. The device of the present invention has both a bone conduction speaker type and a bone conduction earphone type, and is extremely convenient.

The present invention turns the rotary switch to the upper side (use of electricity for charging) or the lower side (use of electricity for battery) to turn on the power when you want to listen to important matters for a short time. The conductive cushion is applied directly to the auricle while pressing the elongated switch on the side of the device.
The choice between the use of electricity for charging or the use of electricity for batteries is usually possible when charging at home, so charging electricity is used. Because there is no electricity, it is often avoided when using at home.

  The present invention applies vibration conduction directly through the ear canal, tympanic membrane, middle ear, and ear ossicles by applying a conduction cushion of a bone conduction audio hearing aid to the auricle, stimulating the conduction acoustic nerve as a part that transmits sound, On the other hand, it is a bone-conduction sound loudspeaker characterized by stimulating the sensory auditory nerve as a part that senses the sound of the cochlea, the auditory deity, and the center, and feeling the vibration as sound.

  The problem to be solved is attached when you want to listen to music for a long time, for example, watching TV, grouping with your family, watching theater, meeting, etc. If you use a bone conduction earphone, you don't have to press the elongated switch next to the bone conduction audio hearing aid, and if you insert a bone conduction earphone jack, it will switch automatically so you can place the instrument on a table or strap it on your neck It is optimal to lower it.

In the present invention, a conductive cushion is provided at a portion corresponding to a speaker of an ordinary loudspeaker, and vibration is directly applied to the external auditory canal by applying it to the conductive cushion of the bone conduction audio hearing aid on the auricle and through the external auditory canal to the tibia and the cutaneous bone.

  The conduction cushion 3 vibration that continues to push the central elongated switch 4 starts, but when it is released, the conduction cushion 3 vibration stops. If the arm is tired after listening for a long time, when the bone conduction earphone jack 21 is inserted into the bone conduction earphone jack hole 22, the conduction cushion 3 automatically switches to stop vibration, and the bone conduction earphone 31 starts to vibrate and can continue to listen. So convenient.

  FIG. 5 is an explanatory view from the plane of the bone-conduction sound loudspeaker 1. The left protrusion is the use of electricity for charging when turned upward by the rotary switch 2, and for the battery when turned downward. It is the use of electricity. Further, when it is turned to the back, the rotary switch 2 becomes the vibration adjuster 2, and it becomes stronger as it is turned to the back. When it is restored, it becomes weaker.

In addition, the bone conduction earphone is 31 and 19 is a strap hanging shaft 19.
The charging jack 23 is inserted into the charging jack hole 24, and the bone conduction earphone jack 21 is inserted into the bone conduction earphone jack hole 22. When the right elongated switch 4 is pressed, the conduction cushion 3 starts to vibrate.

When the rotary switch 2 is turned to the upper side or the lower side, the power is turned on in the first stage, and the vibration regulator 2 is turned on in the second stage. When the elongated switch 4 is continuously pressed, the bone conduction vibrator 25 vibrates, and when it is directly applied to the transmission cushion 3, the bone conduction is generated through the external auditory canal and the entire nerve of the ear is recognized as sound, music, and words.

FIG. 7 is a configuration explanatory view of a central cross-sectional view of the bone conduction vibrator 25 which is fitted into the bone conduction audio hearing aid 1 as the bone conduction vibrator 25.
The bone conduction vibrator 25 is the heart of this device. When the rotary switch 2 is turned upward, the first stage is turned on for charging, and when turned downward, the first stage is turned on for battery. When it is turned further up and down, the second stage becomes the vibration adjuster 2, and the further it is turned, the stronger the vibration.

  When the elongate switch 4 is pressed, electricity is passed to the coil i (the main power source is in the rotary switch 2, and when it is turned upward, it is used for charging electricity, and when it is turned downward, it uses battery electricity / each electricity. ), The plate c, the magnet g, the second plate f, the second magnet e, the substrate d, the diaphragm c, the fastener b, and the cap a.

  When the voltage of the storage battery drops, the light bulb 30 below the bone conduction audio listener 1 glows red. At that time, the AC 100 V jack is inserted into the AC 100 V outlet 28 and at the same time the charging jack 23 is inserted into the charging jack hole 24. It glows blue when the plug-in charge is full. At that time, the charging ends when the charging jack 23 is pulled out. Again, when the voltage drops in the storage battery, the light bulb 30 below the bone conduction sound loudspeaker 1 glows red.

  When the rotary switch 2 is pushed upward, the power is turned on instead of charging electricity, and the bone conduction audio hearing aid 1 starts to operate. Further, when it is turned, it becomes a vibration adjuster 2, and as it is turned, the vibration becomes stronger, and when it is turned back, it becomes weaker. When the elongated switch 4 is pressed while the rotary switch 2 is pressed upward, the transmission cushion 3 vibrates, and when directly applied to the auricle 5, bone conduction occurs through the external auditory canal 6 and the entire nerve of the ear is sound, music, and words. It is something to recognize as.

  When the arm that pushes the long and thin switch 4 is tired after listening for a long time, the bone conduction earphone jack 21 on the opposite side is automatically inserted into the bone conduction earphone jack hole 22 by using the accessory bone conduction earphone 31. When the bone conduction earphone 31 is inserted into the external auditory canal 6, the bone conduction is generated through the vibration of the bone conduction earphone 31 and the entire nerve of the ear can continue to listen to lectures and music. These are electricity for charging, and are usually used for a charger when at home. When the rotary switch 2 is returned to the center, electricity is turned off.

  When the rotary switch 2 is pressed downward, the power is turned on instead of the battery electricity, and the bone conduction audio hearing aid 1 starts to operate. When it is further turned, it becomes the vibration adjuster 2, and as it is turned, the vibration becomes stronger, and when it is turned back, it becomes weaker. If the elongate switch 4 is kept pressed while the rotary switch 2 is pressed downward, the transmission cushion 3 vibrates using the battery electricity, and bone conduction occurs through the external auditory canal 6 when directly applied to the auricle 5. Is recognized as sound and music.

  If the arm that pushes the long and thin switch 4 is tired after listening for a long time, it is automatically switched by inserting the bone conduction earphone jack 21 of the accessory into the bone conduction earphone jack hole 22 so that the lecture or music can be heard continuously. These are electricity for batteries, and electricity for dry batteries is used when going out. When the rotary switch 2 is returned to the center, electricity is turned off.

FIG. 9 is an explanatory diagram of the structure of the ear and its function. The ear hole is called the external auditory canal 6 and is 3.5 cm from the entrance to the eardrum, and the eardrum 7 is at the innermost end of the ear canal 6. In this case, the eardrum 7 is damaged and the eardrum 7 has almost no function, and is a device related to the bone-conduction sound hearing aid 1 in which sound and words are recognized by the function of sound nerves through bone conduction.
The ear canal, tympanic membrane, middle ear, and ear ossicles are parts that transmit sound, and the cochlea, cranial nerves, and central part are collectively called the sensory system.
