Definitions

  • Earphones and headphones that transmit sound to the inner ear are used as sound output devices that can be worn on the head and listen to sound.
  • so-called bone conduction speakers that transmit voice vibration to bones such as the mandible of the head are also used.
  • a plurality of sounding bodies are provided for one ear, and sound waves are emitted by directing a plurality of sound wave emission axes to different portions of the ear canal wall
  • the technique which performs is known (for example, refer patent document 1).
  • a technique for attaching a bone conduction unit to an eyeglass frame and providing a position adjusting means is known as a technique for easily positioning the bone conduction unit (for example, Patent Document 2). reference.).
  • the present invention has been made in view of the above points, and it is an object of the present invention to facilitate identification of front and rear sounds and to easily obtain a good sound conduction state.
  • the first invention is An audio output device for listening to audio by wearing it on the head, There are multiple sounding bodies per one of the left and right ears, At least one of the plurality of sounding bodies is a bone conduction sounding body.
  • the bone conduction sounding body can easily obtain different auditory characteristics depending on the wearing position value, etc. Easy to plan.
  • the second invention is The audio output device of the first invention.
  • the plurality of sounding bodies include a plurality of bone conduction sounding bodies.
  • voice output apparatus It is explanatory drawing which shows the example of a structure which combined the audio
  • the signal output circuit unit 106 receives a signal transmitted from a portable information terminal 500 such as a cellular phone by wireless communication using Bluetooth (registered trademark) as shown in FIG. It outputs to the bodies 102-105.
  • the above audio signal can be used as a hearing aid if a real-time on-site voice input to the microphone 501 of the portable information terminal 500 or a microphone (not shown) provided in the glasses frame 101 is used as a sound source. Instead, it may be audio signals of various sound sources acquired or generated by the portable information terminal 500.
  • the bone conduction sounding bodies 102 to 105 may be simultaneously activated, but only a part may be activated to reduce power consumption. Control for setting only such a part to the operating state may be performed, for example, by sending a control signal from the portable information terminal 500, or to the bone conduction sounders 102 to 105 that are not in the operating state. A silent signal may be sent, or a switch may be provided on the glasses frame 101.
  • the determination of which bone conduction sounding body 102 to 105 is in an operating state can be made in accordance with, for example, the operation of the portable information terminal 500 by the user. Thereby, it is possible to easily perform sound conduction by bone conduction while suppressing power consumption.
  • the bone conduction sounding bodies 102 to 105 to be operated may be selected depending on the type of the sound source. For example, when there is a difference in sensitivity between the bone conduction sounders 102 to 105, when listening to music or having a conversation, the bone conduction sounders 102 to 105 having high sensitivity with respect to highly important sounds are used. While listening to background music, it is possible to reduce the burden of hearing by using relatively low-sensitivity bone-conducting sound generators 102-105 while listening to background music. Good.
  • the earphone 601 may be used in combination with one or a plurality of bone conduction sounders 102 to 105 as shown by a two-dot chain line in FIG. That is, since the earphone 601 and the bone conduction sounding bodies 102 to 105 can easily make the auditory characteristics greatly different, the localization of the sound source due to the difference in the auditory characteristics and the increase in the sense of reality can be facilitated. it can.
  • a lens for correcting vision may be fitted into the lens portion of the glasses frame 101, or a transparent glass or a sunglasses lens may be fitted. Further, a display device may be provided so that realistic viewing is possible at the same time.
  • a headphone type audio output device 450 having an ear pad portion 451 in which the bone conduction sounding bodies 102 to 105 and the acoustic speaker 453 are arranged, and a headband portion 452,
  • a helmet-type audio output device may be configured by combining the above-described configuration with a helmet member that covers the head completely. With these, it is possible to easily fit the head or to give fashion variations.
  • 3 to 7 show examples in which two or four bone conduction sounding bodies 102 and 103 are provided for one of the left and right ears, but the present invention is not limited to this. It is only necessary to include a plurality of sounding bodies including one bone conduction sounding body.

Abstract

Afin de permettre aux sons à l'avant et aux sons à l'arrière d'être facilement distingués les uns des autres ou de faciliter une bonne transmission du son dans un dispositif de sortie audio à porter sur la tête, la présente invention concerne un dispositif de sortie audio (100) à porter sur la tête pour écouter un son comprenant plusieurs corps produisant du son pour l'oreille gauche et droite, dont au moins un de la pluralité de corps produisant du son est un corps producteur de sons à conduction osseuse. La pluralité de corps de production de son peut comprendre une pluralité de corps de production de son à conduction osseuse (102) à (105).
