Abstract

PURPOSE:To ensure hearing of a sound added with an indirect sound component, by providing a diaphragm in addition to a speaker, connecting the diaphragm to a spring and obtaining a reverberation sound from the diaphragm when a sound is produced from a speaker of a headphone. CONSTITUTION:For a headphone, the 2nd diaphragm 4 is set beside a speaker unit 3 consisting of the 1st diaphragm 1 and a magnetic circuit 2. An end of an elastic matter, e.g., a spring 5 is connected to the diaphragm 4. In such a constitution of the headphone, the sound wave radiated from the unit 3 reaches directly the ears and at the same time vibrates the diaphragm 4. The vibrations of the diaphragm 4 repeat reflections many times via the spring 5 and are radiated again by the diaphragm in the form of a reverberation component.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention J The present invention relates to headphones that add reverberant sound when listening to headphones and can provide reproduced sound with a rich sense of presence.

[Technical background of the invention and its problems]

In conventional headphone listening, two-channel stereo signals are supplied directly to the ears without going through a space such as a listening room. However, when a stereo signal is reproduced using loudspeakers, spatial information from the listening room, etc., and distortion reverberation are added to the original signal and reach the ears. Normally, when producing record sources, etc., the reverberations of the playback room are taken into account when mixing. For this reason, conventional headphones only provide tasteless reproduced sound without reverberation components.

[Purpose of the invention]

The present invention eliminates these drawbacks of conventional headphones. To provide headphones capable of listening to not only direct sound but also sound to which indirect sound components are added as in the case of reproduction through a speaker.

[Summary of the Invention] Summary 9 of the present invention is to install a diaphragm separate from a speaker in a closed space sound field reproduced by headphones, and connect the imaging plate with a spring so that sound is emitted from the speaker of the headphones. reverberation is obtained from a separate diaphragm connected to this spring.

[Embodiments of the invention] Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.

As shown in Figure 2, the headphone of the present invention is provided with a second diaphragm 4 arranged in the vicinity of a speaker unit 3 which is constituted by a first diaphragm 1 and a magnetic circuit 2I.

One end of an elastic body, such as a spring 5, is connected to this second vibration @4. The other end of the spring 5 is fixed to a headphone housing 6 (-). In the figure (2), 7 is an ear pad and 8 is a sound absorbing material.

According to such headphones, sound waves emitted from the speaker unit 3 constituted by the first diaphragm 1 and the magnetic circuit 2 reach the ear as direct sound, while causing the second diaphragm 4 to vibrate. The vibration of the second diaphragm 4 is reflected many times by the spring 5 and is radiated back to the diaphragm as a reverberation component.

〔Effect of the invention〕

As a result, with the headphones of the present invention, not only the original signal from the source reaches the ears, but also the sound can be reproduced with the same sense of realism as if it had passed through the indoor acoustic space.

In addition, as another configuration example of the present invention, a plurality of diaphragms and springs are installed, and complex reverberation such as a ball sound can be added.

[Brief explanation of drawings]

The drawing is a diagram showing the configuration of headphones according to an embodiment of the present invention.

Claims (1)

[Claims] In headphones with speakers placed near each ear, reverberation is added by providing a separate diaphragm near the speakers and an elastic body connected to the diaphragm at one end and connected to the headphone casing at the other end. Headphones characterized by being equipped with a device.
