Embodiment Construction

[0030] Hereinafter, a bone conduction wave output device 1 according to an embodiment of the present invention will be described with reference to the attached drawings.

[0031] figure 1 It is a plan view showing a state where the bone conduction wave output device 1 is worn on the head H of a person.

[0032] (bone conduction wave exporter 1)

[0033] Such as figure 1 As shown, the bone conduction wave output device 1 of the present embodiment is a so-called headphone type output device, and includes a first output unit 2a and a second output unit that are provided at a predetermined distance from each other corresponding to one ear. 2b output section 2, and equipped with figure 1 The output unit 2 of the first output unit 2 a and the second output unit 2 b provided on the side opposite to the one shown corresponds to the other ear.

[0034] In addition, the output part 2 provided corresponding to the other ear is also connected with the figure 1 The configuration shown...

Abstract

Provided are a bone conduction wave generation device, a bone conduction wave generation method, a bone conduction wave generation device program, and a bone conduction wave output apparatus that havethe purpose of reducing sound leakage from a bone conduction speaker (output unit). A bone conduction wave generation device 10 according to the present invention is provided with a waveform generation unit 13a that generates a first output wave f(t) and a second output wave g(t) for bone conduction, wherein the waveform generation unit 13a generates, on the basis of an input wave s(t), the firstoutput wave f(t) and the second output wave g(t) that are outside the audible range and that are to be a synthesized wave p(t) having an audible beat by being synthesized.

Description

technical field [0001] The present invention relates to a bone conduction wave generating device and method, a program for the bone conduction wave generating device, and a bone conduction wave output machine. Background technique [0002] For example, a general headphone or earphone is worn such that a speaker (output unit) that outputs sound is aligned with the ear hole. [0003] Then, the sound waves output from the speaker vibrate the air, and the vibration of the air vibrates (vibrates) the eardrum through the external auditory canal. [0004] Then, the vibration of the eardrum is transmitted to the three auditory ossicles (stapes, incus, and malleus) located on the inner side of the eardrum, and then transmitted to the cochlea located on the inner side of the auditory ossicles. [0005] The vibration reaching the cochlea causes the lymph fluid in the cochlea to vibrate and stimulate the hair cells, and the stimulation is converted into electrical signals by the hair c...
