Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to headphones provided with a vibrator for vibrating the headphones themselves.

B. Outline of the Invention The present invention provides a headphone equipped with a vibration exciter, in which a speaker unit and a vibration exciter are vertically displaced by a predetermined amount and arranged in a housing, so that a stable wearing feeling can be obtained, and the housing The thickness of the portion can be reduced.

C. Conventional Technology Conventionally, a headphone has been proposed in which a low-frequency component of a reproduction signal is supplied to an exciter to vibrate the headphone itself so that the user can experience the vibration (Japanese Patent Laid-Open No. 60-84).
095 publication). In such headphones,
The exciter is configured so that the magnetic circuit side moves as a vibrating body.

D. Problems to be Solved by the Invention By the way, since the headphone as described above includes the speaker unit and a vibration exciter that is heavier than the speaker unit, it is difficult to balance during wearing. , Stability was not so good. In addition, the thickness of the housing portion that houses the speaker unit is generally increased by the amount of the vibrator, and when used in a small portable tape recorder, for example, it is bulky to carry.

Therefore, the present invention has been proposed in view of the above-mentioned conventional problems, and an object of the present invention is to provide headphones that are well-balanced and provide a stable wearing feeling. It is another object of the present invention to provide headphones that have a thin housing portion and are not bulky to carry.

E. Means for Solving the Problems In order to solve the above-mentioned problems, the headphones according to the present invention include a speaker unit to which a reproduction signal from a signal source is supplied and a low frequency component of the reproduction signal. An exciter to be supplied, a housing for accommodating the speaker unit and the exciter, and an ear pad provided on a front surface side of the housing are provided, and the exciter is located at a lower position with respect to the speaker unit. And is housed in the housing.

F. Action According to the present invention, since the shaker heavier than the speaker unit is arranged below the speaker unit, a stable wearing feeling can be obtained, and the thickness of the housing portion can be reduced.

G. Example Hereinafter, one example of the present invention will be described in detail with reference to the drawings.

FIG. 1A is a side sectional view showing a main configuration of headphones according to an embodiment, and FIG. 1B is a front view thereof. In these FIGS. 1A and 1B, the speaker unit 1 to which the reproduction signal from the signal source is supplied is attached to the baffle 2 and the vibration unit to which the low frequency component of the reproduction signal is supplied is applied. The device 3 is the speaker unit 1 of the baffle 2.
It is attached to a lower position via a fixing member 4. The housing 5 is fixed to the baffle 2, and the speaker unit 1 and the vibrator 3 are housed in the housing 5. That is, in the housing 5,
The speaker unit 1 and the vibration exciter 3 are arranged vertically offset from each other by a predetermined amount. That is, as shown in FIG. 1A, the vibrator 3 is located below the speaker unit 1 and is housed in the housing 5. The substantially elliptical ear pad 6 is not breathable, and is fixed to the baffle 2 on the front side of the housing 5, that is, the sound emitting side of the speaker unit 1. The headband 7 is attached to the housing 5 via the headband adjusting portion 7a.

The vibrator 3 has a structure as shown in FIG. 2, for example. In FIG. 2, a yoke 12 is arranged on one magnetic pole side of the magnet 11 and a yoke plate 13 is arranged on the other magnetic pole side. The magnet 11, the yoke 12, and the yoke plate 13 that form the magnetic circuit are the protrusions 14a provided on the inner surface of the cylindrical case 14.
It is sandwiched by the spacer 15 and the spacer 15, and is fixed to the inner surface of the case 14. A damper 16 is provided on one open surface of the case 14, and a damper 17 is provided on the other open surface. For the dampers 16 and 17, for example, spring members having a shape as shown in FIG. 3 are used. The damper shown in FIG. 3 is a so-called butterfly damper.

Further, one end of a voice coil bobbin 19 around which a voice coil 18 is wound is fixed to the inner surface side of the case 14 of the damper 16. Here, the voice coil 18 is mounted so as to be located between the yoke 12 and the yoke plate 13. The respective central portions of the damper 16 and the damper 17 are connected and fixed via a support body 20. Further, the fixing member 4 is connected to the support 20 via the damper 16. The vibration exciter 3 configured in this manner is heavier than the speaker unit 1 in order to generate effective vibration.

In the headphone having the above-described structure, when the low frequency component of the reproduction signal is supplied to the voice coil 18 of the vibrator 3, the voice coil bobbin 19 is fixed to the baffle 2 via the damper 16 and the fixing member 4. Therefore, mechanical vibration occurs in the magnetic circuit system including the magnet 11, the yoke 12, the yoke plate 13, and the like. Then, this mechanical vibration becomes the vibration of the headphones themselves, which is felt. Here, since the vibration exciter 3 which is heavier than the speaker unit 1 is arranged below the speaker unit 1 at a predetermined interval, a good balance and a stable wearing feeling can be obtained. Further, the thickness of the housing 5 can be made thinner than that in the case where the speaker unit and the vibrator are arranged on the same straight line in the thickness direction, and when used for a portable small tape recorder or the like, it is easy to carry. It is not bulky and convenient. Further, the chin and the vicinity of the lower side of the ear, which are highly sensitive to the human body, are shaken, and a larger sensation effect (realistic feeling) is obtained.

In addition, in the above-described embodiment, the vibration exciter 3 is attached to the baffle 2, but it may be attached to the housing 5 side.

H. Effect of the Invention As is apparent from the description of the above-described embodiments, according to the headphones of the present invention, the vibrator that is heavier than the speaker unit is arranged in the housing at a position below the speaker unit. It has a good balance and a stable wearing feeling. In addition, the thickness of the housing can be reduced, which is convenient because it is not bulky to carry. Furthermore, the vicinity of the lower side of the chin and the ear is shaken, and a larger sensation effect is obtained.
