Description

  The present invention relates to a sound transmission device that transmits vibrations to the human body and transmits vibrations to the eardrum by vibrating the auricles, and also generates air conduction sound in the ear canal by vibrations and transmits it to the eardrum.

  2. Description of the Related Art Conventionally, headphones and the like often use an ordinary speaker that generates air conduction sound in which sound is transmitted by vibration of air. This conventional headphone or the like requires a shape in which the earphone is inserted or covered in the external auditory canal, and it is difficult to hear external sounds. Further, conventional headphones have a problem that they are difficult to hear in a noisy environment.

  On the other hand, a headphone using bone conduction, which is an audio transmission method that can eliminate sound leakage and is easy to hear even in a noisy environment, is known (for example, Patent Document 1). Bone conduction is a voice transmission method in which vibration corresponding to voice is transmitted to the skull of the human body, and the vibration is transmitted to the cochlea which is a hearing organ through the bone and recognized as voice. Accordingly, in bone conduction, air conduction sound that is transmitted by sound of air is not generated, and sound is transmitted without using the eardrum.

(First embodiment)
FIG. 1 is a diagram illustrating an audio transmission device 100 according to the first embodiment.
FIG. 2 is a diagram illustrating a state in which the audio transmission device 100 is worn on the ear.
FIG. 3 is a diagram illustrating the vibration generating unit 110 seen through from the normal direction of the plane of the vibrating unit 112.
FIG. 4 is a diagram showing a DD cross section indicated by an arrow in FIG. 3.
FIG. 5 is a block diagram illustrating a usage state of the audio transmission device 100.

  The audio transmission device 100 includes a vibration generating unit 110, a holding unit 120, and a wiring 130.

  The vibration generating unit 110 includes a vibrator 111, a vibrating unit 112, a double-sided tape 113, a frame member 114, and a base material 115.

  The vibrator 111 is driven by the drive signal generated by the drive circuit 140 based on the audio signal in the audible frequency band amplified by the amplifier circuit 151 or the like, and performs vibration according to the audio signal. Further, the entire surface of the vibrator 111 is affixed to the vibrating portion 112 using the double-sided tape 113, and the vibration of the vibrator 111 is transmitted to the vibrating portion 112 as it is.

  The vibrator 111 of this embodiment is a piezoelectric ceramic bimorph element and is driven in a bending mode (flexural vibration). The piezoelectric material used for the vibrator 111 is an element in which high-displacement piezoelectric materials are stacked. By applying a voltage faithful to the audio signal from the amplifier to the piezoelectric element, the vibrator 111 (as a result) Vibrate to reproduce.

The vibration part 112 is a thin plate-like member, and a peripheral part thereof is fixed to the base material 115 using an adhesive or a double-sided tape. Further, as described above, the vibrator 111 is attached by the double-sided tape 113 near the center of the vibration part 112. Therefore, when the vibrator 111 vibrates, the vibration unit 112 performs flexural vibration together with the flexural vibration of the vibrator 111.
As the vibration part 112 of this embodiment, although resin materials, such as an acryl and PET, are desirable, a glass material may be sufficient. Moreover, the outer side of the vibration part 112 may be further covered with silicon rubber to improve the touch.

  The double-sided tape 113 is an adhesive member for joining the vibrator 111 and the vibrator 112.

  The frame member 114 is a member that forms a side opposite to the vibration unit 112 of the vibration generation unit 110 and an outer peripheral region. A gap S is provided between the frame member 114 and the vibrator 111. By providing this gap S, it is possible to prevent the vibrations of the vibrator 111 and the vibration part 112 from being hindered.

Generated, transmitted to the eardrum, and recognized as the final sound. Conventional bone conduction does not use the tympanic membrane because the skull is vibrated and the sound is recognized by sending vibration directly to the inner ear (cochlea, semicircular canal, etc.). On the other hand, this method is greatly different from bone conduction in that the ear canal is once shaken to generate sound vibration (air conduction sound) by the air, and the same recognition as normal sound is made through the eardrum. Further, since it is not necessary to vibrate the bone, voice can be transmitted even if the vibration is weaker than bone conduction.

  The holding | maintenance part 120 is formed so that it can be inserted and installed inside the tragus 2b and the antitragus 2c. The holding unit 120 is connected above the vibration generating unit 110 so as to hold the vibrating unit 112 in contact with the auricle above the earlobe 2d.

One end of the wiring 130 is connected to the vibrator 111. Further, the other end of the wiring 130 is connected to the playback device 150 or the like using a connector or the like (not shown).

  The drive circuit 140 is a circuit that converts the audio signal sent from the playback device 150 into a signal in a form suitable for driving the vibrator 111. The function of the drive circuit 140 may be built in the playback device 150 or may be provided as part of the audio transmission device 100.

The playback device 150 includes an amplifier circuit 151 and an output unit 152. The playback device 150 may have any form as long as it is a device that outputs sound, such as a portable music player, a mobile phone device, a television receiver, or the like.
The amplifier circuit 151 is an amplifier that amplifies an audio signal such as music to be reproduced.
The output unit 152 is a terminal that outputs audio from the playback device 150.

  As described above, the audio transmission device 100 of the present embodiment is connected above the vibration generating unit 110 so that the holding unit 120 holds the vibrating unit 112 in contact with the auricle above the earlobe. Vibration can be reliably transmitted to the auricle without giving the user a sense of discomfort or discomfort. Moreover, since the audio | voice transmission apparatus 100 comprised the holding | maintenance part 120 by simple structure, it can be set as a small and lightweight apparatus. In addition, by using a piezoelectric ceramic vibrator as an exciter, the sound transmission device 100 can enjoy music with the ear canal open, and the ear can not be hot even during long periods of use or in hot summer, and can enjoy listening with a sense of openness. . In addition, the audio transmission device 100 can maintain confidentiality with little sound leakage. Furthermore, the sound transmission device 100 concentrates on the eardrum side when the open ear hole is closed with a hand, so that the sound pressure naturally increases and blocks the noise from the outside world. However, it is possible to hear the voice clearly. Furthermore, since the sound transmission device 100 does not need to vibrate bones, it can transmit sound even if the vibration is weaker than bone conduction, and thus the vibration generating unit 110 can be formed in a small size. Moreover, since the audio transmission device 100 does not need to strongly press the vibration unit 112 against the human body, it is difficult for the user to feel uncomfortable. Furthermore, the power consumption required by the connected playback device 150 can be kept low.
