Abstract

In stereo sound reproduction, we provide an acoustic ring that clarifies sound image localization in the installation space with a simple structure and installation method. [Solution] The acoustic ring has a coil-shaped portion formed by winding a wire multiple times and a straight portion, and the ends of the wire are electrically connected to form a ring. The acoustic ring is installed between the left and right speakers in the listening space, in the space behind the viewer, or near the viewer.

Description

Technical Field

[0001] The present invention relates to an accessory for adjusting the sound field characteristics in the playback space of an audio device, and particularly to an acoustic ring that contributes to clarifying the sound image localization during stereo playback.

Background Art

[0002] In conventional stereo audio devices, due to the shape of the installation space and the influence of reflections, the energy distribution of the sound field may be disturbed, and the sound image localization may become unclear. Conventional technologies for improving this include mainly acoustic panels, sound-absorbing materials, or acoustic signal processing devices that perform electronic correction, and the means that can be easily installed are limited.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Conventional technologies require complex devices and large-scale equipment, and the means for easily adjusting the sound field characteristics of the acoustic space are insufficient. The present invention aims to solve this problem by using a ring having a simple structure.

Means for Solving the Problems

[0006] ​Using a conductive wire, a coil portion formed by winding the wire multiple times and a straight portion are configured, and both ends of the wire are conductively connected to form an annular acoustic ring. By installing this ring in the middle of the left and right speakers of a stereo playback device, in the space behind the viewer, or near the viewer, the sound field characteristics in the acoustic space are adjusted.

Advantages of the Invention

[0007] According to the present invention, by installing this ring in the acoustic playback space, the clarity of sound image localization can be achieved with a simple structure and installation method.

Embodiments for Carrying Out the Invention

[0009] Embodiments of the present invention will be described with reference to the accompanying drawings.

Examples

[0010] 1. Ring shape As shown in FIGS. 1 to 4, this ring is composed of a coiled portion (1-a) formed by coiling a wire made of an outer skin and a conductor, and a straight portion (1-b). Both ends of the wire are electrically connected to form a ring shape. 2. Diversity of ring shapes 1) The straight portion may be configured to pass through the outside or inside of the coil shape. 2) The direction of the straight portion may be perpendicular or oblique to the winding direction. By setting it as an oblique direction, the stress of the wire is relaxed and the production becomes easy. 3) The electrically connected portion of the wire may be any part of the ring formation path. For example, FIGS. 1 (1-c), (1-d), FIGS. 2 (2-a), (2-b), etc. are acceptable. [[ID=z18]] 3. Examples of requirements in the configuration 1) It is desirable that the wire used has a relatively low impedance from direct current to the high-frequency band. 2) As an example in design, the winding direction of the coil-shaped portion can be unified in a certain direction. When viewed from above in FIG. 1, when wound in a clockwise rotation, it is desirable that the number of turns increases upward. In the case of counter-rotation, the effect may decrease. 3) The winding diameter is set to about 30 mm in consideration of the installation property. 4) The number of turns is appropriately set according to the installation environment. 5) The ring can be installed near the center between the left and right speakers or at a predetermined position within the viewing and listening space.

Industrial applicability

[0011] The present invention can be used not only to improve sound field reproduction in home audio equipment, but also as an accessory to assist in adjusting sound field localization in professional music studios and the like. ​ [Explanation of Symbols]
