Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to headphones and sound reproducing devices used for audio listening in audio equipment, television receivers, and the like.

(b) Conventional technology Conventional headphones include, for example, Japanese Patent Application Laid-Open No. 60-84095.
As shown in the publication (HO4RIlo O), speaker sections are provided at both ends of the headband, and the structure is such that the speaker sections cover the ears when worn.

(c) Problems to be Solved by the Invention However, conventional headphones have a feeling of pressure because the speaker part covers the ears, and it is difficult to hear external sounds other than the music being listened to. Furthermore, since the sound image is localized in the head, there are problems such as an unnatural feeling.

On the other hand, recently, as shown in Fig. 13, in addition to the L/R 2 channel speakers (51) and (52), there were
), speakers (53) (54) are also arranged behind the speakers (53) (54), and the rear speakers (53) (54) reproduce pseudo-reverberant sound, creating a so-called surround system that gives a sense of realism to the reproduced sound. A system called .

However, due to space issues, noise issues, etc., it may be desirable to be able to listen to reproduced sound with a sense of realism as described above using headphones, but this cannot be achieved using conventional headphones.

In addition, Japanese Patent Publication No. 49-39002 (102A5) discloses a four-channel system in which speakers for reproducing each channel are installed in the front and rear of each of a pair of headphone bodies, and the rear channels have phases opposite to the front channels. Headphones are shown, but if the phase is reversed, pseudo-reverberant sound will be produced, similar to modern surround systems.
Furthermore, even if the rear speakers reproduce pseudo-reverberant sound, the front and rear speakers are close to each other, and each speaker is located approximately to the side of the ear, so the reproduced sound cannot be reproduced. It is difficult to provide a sufficient sense of realism.

SUMMARY OF THE INVENTION An object of the present invention is to provide headphones that do not cause the above-mentioned problems such as a feeling of pressure and can be compatible with a surround system. Furthermore, it is an object of the present invention to provide a sound reproduction device capable of selectively switching the speakers to be used when headphones compatible with the above-mentioned surround system and cabinet-type speakers are used in combination. .

(d) Means for Solving the Problems The headphones of the present invention are supported by support parts extending forward and/or rear from both ends of the temporal clamping part, and have a pair of speakers at positions spaced apart from positions corresponding to the ear parts. It is characterized by being provided with. Further, the front speaker is a main channel speaker, and the rear speaker is a surround channel speaker. Further, the speaker is characterized in that the front speaker is arranged at a lower position and the rear speaker is arranged at a higher position with respect to the vicinity of the center of the position corresponding to the ear. Further, the support section is characterized in that it includes an adjustment mechanism that adjusts the position of the speaker or a moving mechanism that moves the speaker to a position where it is not used.

Furthermore, the headphones of the present invention include a pair of bass speakers disposed at positions corresponding to the ear portions at both ends of the temporal clamping portion, and a support portion extending forward and/or rearward from the both ends.
It is characterized by a pair of speakers. The present invention is also characterized by comprising a vibration prevention member that prevents vibrations generated from the speaker supported by the support portion extending forward from being transmitted to a speaker housing in which a bass speaker or the like is disposed. .

Further, in a sound reproduction device including headphones including a main channel speaker and a surround channel speaker, a cabinet type speaker, and a speaker drive means for supplying an acoustic signal to each speaker, the headphone and/or speaker drive means: The apparatus is characterized by comprising a switching means for selectively switching supply/cutoff of the acoustic signal.

(E) Function Since the present invention is installed at the bottom of the tank as described above, the sound image of the reproduced sound is localized in front or behind the ear, and if the rear speakers are speakers for the surround channel, You can get a rich playback sound. In addition, the height of the position where the front, rear, and partner sound images are localized can be perceived as being in the middle of a road.

Further, by adjusting the adjustment mechanism, the speaker can be placed at an optimal position, and by the moving mechanism, the speaker can be moved to a position where it is not used.

In addition, when a pair of bass reproduction speakers are arranged at each end of the temporal clamping part, since the bass reproduction speakers are placed close to the ear parts, sufficient bass reproduction sound can be obtained. . Furthermore, the vibration prevention member prevents vibrations generated from the speaker supported by the support portion extending forward from being transmitted to the speaker housing in which the bass speaker or the like is disposed.
