Description

Chair with multi-channel sound system

Technical Field

The present utility model relates to a chair having a multi-channel sound system, and more particularly, to a chair having a multi-channel sound system that can provide a user sitting on the chair with a spatial sense to a stereoscopic sense by sound output from a plurality of channels.

Background

In general, a speaker connected to a computer converts a current flowing through an electric wire into an electric signal and vibrates the electric signal with a vibration unit to generate a sound.

For example, in the case of watching a movie or playing a game through a computer, a user can watch a video of a screen of the computer with eyes while sitting on a chair capable of seeing a display of the computer, and a speaker vibrates by transmitting an electric signal, and the vibration corresponding to the video is transmitted to the user's ear, whereby the user can listen to the sound.

In particular, in the case of a multi-channel audio system including a plurality of such speakers, there is an advantage in that a user can more precisely experience the direction, size, and the like of sound in a video.

However, in order to realize such a multi-channel audio system, speakers should be disposed on a desk, under a desk, or behind a chair, respectively, and all of the plurality of speakers should be electrically connected, which is a significant limitation in terms of space.

In addition, even if a multi-channel sound system is realized by disposing a plurality of speakers, there are problems in that the position of a chair is changed or various physical disturbances exist between a user sitting in the chair and the speakers.

At least one main frame 110 is provided at an arbitrary region of the chair 100, and the at least one main frame 110 has a shape extending in a direction toward the front of the user through a side of the user seated on the chair 100.

Here, an arbitrary region of the chair 100 in which the main frame 110 is provided refers to the headrest portion H, the backrest portion B, the seat portion S, and/or the side support portion a that constitute the chair 100.

Hereinafter, first, an embodiment in which the main frame 110 is provided on the backrest portion B will be described.

At least one main frame 110 is provided at the backrest part B, the at least one main frame 110 extends in a forward direction by a predetermined length, and at least one speaker 120 is provided along the extending direction of the main frame 110 to define a first speaker arrangement area SA. The forward direction is a direction toward the front of the user sitting on the chair 100, and is a direction toward an arbitrary position located relatively forward with respect to at least the two side surfaces of the user sitting on the chair 100. That is, in this case, one end portion of the main frame 110, which is not fixed to the chair 100, may be located in a front view of a user sitting on the chair 100. In this way, the main frame 110 is shaped to surround the user while being spaced apart from the user sitting in the chair 100 by a predetermined distance, so that an effect that sound emitted through at least one speaker 120 provided in the main frame 110 is emitted from an arbitrary space surrounding the user can be achieved.

For example, referring to fig. 1, a main frame 110 is provided in or behind the backrest portion B, a first speaker installation area SA is defined along the extending direction of the main frame 110, and a plurality of speakers 120 are preferably provided in the first speaker installation area SA.

If the main frame 110 is provided inside the backrest part B, the main frame 110 may have a shape protruding in at least one of both side surface directions of the backrest part B to extend a predetermined length in a front direction of the chair 100.

On the other hand, in the case where the main frame 110 is disposed behind the backrest portion B, in order to bear the load of the main frame 110, a separate support member that fixes the main frame 110 and the backrest portion B may be provided. In this case, the main frame 110 is provided on the separate support member and has a shape extending a predetermined length from the rear of the backrest B toward the front of the chair 100.

In order to realize a multi-channel sound system, the main frame 110 provided at the backrest part B may be provided with an appropriate number. For example, as shown in fig. 2, two main frames 110 may be provided in or behind the backrest part B.

On the other hand, the speaker 120 is integrally formed with the main frame 110, or is detachable from the main frame 110. In another modification, a plurality of speakers 120 may be connected to each other to form the main frame 110.

Here, the speaker 120 may be a speaker unit, a display type speaker, or a film type speaker, which is connected to a driving part separately disposed in the first speaker installation area SA to operate as a finished product, and includes a single-path speaker and a multi-path speaker, and may be operated by receiving a sound signal by wire or wirelessly. The description of the speaker 120 is also applicable to a speaker disposed in a second speaker arrangement area to be described later.

On the other hand, although not shown separately, in the case where the speaker receives sound wirelessly, the chair 100 may include a wireless receiving part. The wireless receiving part can perform wireless transceiving with sound sources (such as home cinema, TV, set-top box, bar-shaped sound, computer, mobile phone, tablet, etc.) through a mode such as WiFi, bluetooth, DECT or LIFI. The wireless receiving portion may be disposed at a fastening portion and/or a connecting portion to be described later. On the other hand, the wireless receiving unit may be provided in any area of the chair 100.

In addition, the speaker 120 may be directly disposed on the first speaker disposition area SA, but is not necessarily limited thereto, and a component for disposing a speaker may be additionally disposed between the first speaker disposition area SA and the speaker 120.

On the other hand, the main frame 110 may have a linear shape extending a predetermined length from the backrest part B in a front direction of the chair 100 (or in a direction toward the front of the user through a side of the user seated on the chair 100). In addition, the main frame 110 may have various shapes other than a straight line, such as a bending line, a curved line, etc., according to the need. In this case, the main frame 110 may take a shape surrounding the user seated in the chair 100. Accordingly, if a plurality of speakers 120 are provided at the main frame 110, a constant distance between the plurality of speakers 120 and the user can be maintained. In addition, in the case where the main frame 110 is provided with a plurality of speakers 120 of different performance, the distance between each speaker 120 and the user may be adjusted in consideration of the performance of the speakers 120.

The shape of the main frame 110 is also applicable to a setting frame, a first main frame, a second main frame, a first sub-frame, a head frame, and a second sub-frame, which will be described later, as long as the shape does not exceed the scope of the present utility model.

Referring to fig. 3 and 4, a main frame rotation shaft 113 is provided in or behind the backrest portion B, and the main frame 110 is configured to be connected to the main frame rotation shaft 113 so as to be rotatable within a predetermined angular range with respect to an axial direction of the main frame rotation shaft 113.

For example, the main frame 110 is connected to the main frame rotation shaft 113 to be rotatable in a vertical or horizontal plane. Here, the vertical plane means a plane orthogonal to any horizontal plane parallel to the ground in the up-down direction, and the horizontal plane means a plane parallel to the ground or to any horizontal plane parallel to the ground.

Although not shown separately, according to another modification of the present utility model, the main frame rotation shafts 113 may be disposed on both sides of the backrest portion B, and the two main frames 110 may be connected to the main frame rotation shafts 113 disposed on both sides of the backrest portion B, respectively, and may extend in the front direction of the chair 100.

In another embodiment of the present utility model, a setting frame 111 extending in the up-down direction is provided in or behind the backrest part B, and the main frame 110 may be provided on the setting frame 111.

If the backrest part B has a shape bent by a predetermined angle or is bendable, the setting frame 111 may be provided in a state of being spaced apart from the backrest part B by a predetermined interval in order to maintain the pointing angle of the main frame 110.

At this time, the main frame 110 may be disposed parallel to a plane perpendicular to the ground in a state of being spaced apart from the backrest part B by a predetermined distance, but is not necessarily limited thereto, and may be disposed to be inclined at a predetermined angle to the plane perpendicular to the ground.

For this purpose, at least one distance adjusting element 112 can be arranged between the backrest part B and the setting frame 111. The interval adjusting part 112 serves to adjust the interval between the backrest part B and the setting frame 111 and simultaneously adjust the angle of the setting frame 111 at the backrest part B.

In addition, the main frame 110 may be disposed on the disposition frame 111 through the main frame rotation shaft 113. In this case, the main frame rotation shaft 113 may be configured to be capable of being lifted and lowered along the extending direction of the installation frame 111, and as a result, the main frame 110 connected to the main frame rotation shaft 113 may be lifted and lowered along the extending direction of the installation frame 111 together with the main frame rotation shaft 113.

Here, the main frame 110 may be configured to be separated from the main frame rotation shaft 113, or the main frame rotation shaft 113 may be made separable from the setting frame 111 in a state where the main frame 110 is connected to the main frame rotation shaft 113.

In this case, in a case where the installation frame 111 is located in or behind the backrest portion B, the installation frame 111 and the backrest portion B may be integrally formed. In addition, the setting frame 111 may be configured to be detachable from the backrest part B, if necessary.
