Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a headphone capable of selecting frequency characteristics according to a music source.

[0002]

[Prior art]

 Conventional headphones are compatible with all music sources, so their frequency characteristics are set to average.

[0003]

[Problems to be solved by the device]

 However, it is not always possible to enjoy music in good condition with conventional headphones in which the frequency characteristics are set to average. For example, with open-air headphones, the sound of the headphones leaks into the surroundings, and it is usually difficult to hear them in the low frequency range.

Although it is possible to electrically change the frequency characteristic, this makes the headphones larger and heavier and more expensive.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a headphone that can obtain a frequency characteristic matched to a music source with a simple configuration.

[0006]

[Means for Solving the Problems]

 The headphone according to the present invention is a headphone having an ear pad that covers the baffle portion, and a substantially ring-shaped rib is detachably attached between the baffle portion and the ear pad.

Plan view, FIG. 4 is an enlarged sectional view of an essential part of the headphones according to the second embodiment of the present invention, FIG. 5 is a schematic sectional view of the headphones according to the third embodiment of the present invention, and FIG. FIG. 7 is a schematic front view of a headphone according to an embodiment of the idea, and FIG. 7 is a graph showing an effect of the headphone according to the present invention.

The headphone according to the present embodiment is a headphone having an ear pad 130 that covers the baffle portion 120. The baffle portion 120 has a plurality of sound holes 121 formed therein and surrounds the sound hole 121. A substantially concave groove 122 is formed, and a substantially ring-shaped rib 140 is detachably attached to the concave groove 122 so that the rib 140 is interposed between the baffle portion 120 and the ear pad 130. .

First, the overall configuration of the headphones will be described with reference to FIG. The headphones are connected to a curved metal head band 200, two ear pads 100 slidably attached to both ends of the head band 200, and a driver 300 incorporated in the ear pads 100. The cord 400 and the jack 500 attached to the tip of the cord 400.

The ear pad 100 includes a main body 110 having a hanger portion 111 extending therefrom, a baffle 120 attached to the main body 110, a driver 300 attached to the baffle 120, and the baffle. It has a sponge ear pad 130 that covers 120.

The main body 110 includes a driver storage portion 112 having a substantially thin plate shape and a substantially circular shape in a plan view, and a hanger portion 111 extending from the driver storage portion 112. The hanger portion 111 is a portion into which the headband 200 is slidably inserted, and is configured to adjust the position of the earpiece portion 100 with respect to the headband 200.

The baffle portion 120 has a plurality of sound holes 121 formed in the central portion. The sound hole 121 guides sound from the driver 300 attached to the back surface side of the baffle portion 120. Further, a substantially ring-shaped groove 122 is formed on the front surface side of the baffle portion 120. It is assumed that the sound hole 121 is opened only inside the groove 122. The groove 122 is used when the rib 140 is detachably attached.

The rib 140 is dimensioned so as to fit in the groove 122. Specifically, the diameter is about 45 mm to 50 mm in order to keep the ear and the headphone sealed, and the height is set to about 1.5 mm to 2.0 mm so as not to feel uncomfortable when wearing the headphones. .

When such ribs 140 are attached to the baffle portion 120, all the sound holes 121 are surrounded by the ribs 140, so that the sound from the driver 300 is prevented from leaking to the surroundings. Therefore, the frequency characteristic in the bass range is improved as shown by the broken line in FIG. The solid line in FIG. 7 shows the frequency characteristics of the conventional headphones.

Therefore, when a music source in which the low frequency range is important is to be enjoyed, the rib 140 is attached to the baffle section 120, and when enjoying a music source which requires a natural frequency characteristic as a whole, the ribs are removed from the baffle section 120. Remove 140.

Although the rib 140 is interposed between the baffle portion 120 and the ear pad 130 by the concave groove 122 of the baffle portion 120 in the above-described first embodiment, the present invention is not limited thereto. It is not limited. For example, as shown in FIG. 4, a concave groove 131 into which the rib 140 is fitted is formed on the inner surface side of the ear pad 130, and the rib 140 is fitted into the concave groove 131, whereby the rib 140 is baffled. You may make it interpose between 120 and the ear pad 130.

In addition, in the above-described first and second embodiments, the rib 140 is detachably attached to the baffle portion 120 or the like, but this is as described below with reference to FIG. May be.

In such a headphone, the rib 600 is formed in the baffle portion 120 by opening an annular opening 123, and the rib 600 is screwed into the opening 123 so as to be able to move forward and backward, and the degree of screwing of the rib 600 is changed so that the rib 600 is ribbed. It is configured to move the 600 into and out of the opening 123. A male screw portion (not shown) is formed on the outer peripheral surface of the rib 600, and a female screw portion (not shown) corresponding to the male screw portion is formed on the inner peripheral surface of the opening 123. Further, the rib 600 is formed with an operation knob 610 protruding to the outside of the main body 110 of the ear pad 100.

[Effect of device]

 The headphone according to the present invention is a headphone having an ear pad for covering the baffle part, and a substantially ring-shaped rib is detachably attached between the baffle part and the ear pad. It is possible to obtain frequency characteristics.

When the rib is attached to the baffle portion, it surrounds all the sound holes formed in the baffle portion. Therefore, when the rib is attached to the baffle portion, the frequency characteristic in the low frequency range is shown in FIG. As shown by the broken line in FIG.

Further, since the diameter of the rib is set to 45 mm to 50 mm and the height of the rib is set to 1.5 mm to 2.0 mm, there is no discomfort when wearing the headphones.

In addition, in a headphone having a baffle portion having an annular opening and a rib screwed into and out of the opening, it is not necessary to remove the ear pad to change the frequency characteristic. It is very convenient.
