Abstract

The present invention relates to a movable chair with a multi-channel speaker. In particular, the chair of the present invention has a headrest, a back support, a seat, and an armrest, and is provided with a speaker, so as to be freely movable in all directions in a state in which a user is seated by a seat support unit with wheels. In a conventional moving chair, it is difficult to install a multi-channel speaker due to risks of displacement and disconnection of a cable connected from the outside, so that only a two-channel stereo speaker outputting in left and right sides is installed on the exterior thereof, and various sound effects cannot be expected. To solve these problems, in the movable chair of the present invention, a wired or wireless surround multi-channel speaker is provided, which ranges from 1 to 32 channels to output sound by separating sound sources in the up-and-down direction as well as in the back-and-forth and left-and-right directions to suit each speaker, thereby being utilized in playing games, listening to music, and watching movies. To this end, the present invention comprises: a left-side speaker installation stand; a right-side speaker installation stand; and at least one speaker.

Description

Multi-channel speaker mounted movable chair}

The present invention is a chair that has a headrest, a backrest, a seat, an armrest, and is equipped with an acoustic cable 14 and a speaker connected from the outside, and is capable of moving in a free direction in a seated state with a seat support part equipped with wheels, 1 Multi-channel wired or acoustic wireless speakers (hereinafter referred to as wireless speakers) ranging from four channels to 32 channels are mounted on the chair, and multi-channel speakers are installed on the speaker mounting table mounted on the headrest, backrest, seat, and armrest. The speaker protects the direction from external shocks, and the woofer speaker 78 is also installed to listen to multi-channel sound sources in a narrow space inside the chair without the need for a large space, and the microphone 28 can communicate with other gamers, and the display A type speaker 30 is mounted on the chair, and a channel processing device 17 is installed on one side of the chair so that multi-channel sounds and images can be heard or viewed in a space inside the chair without expensive devices (eg receiver). It is about a portable chair equipped with speakers.

There have been attempts to install a speaker on a chair because the speaker is closer than the far one can minimize external acoustic interference even with low power.

The'PC room chair' published in the Korean Patent Registration 2001721490000 has two stereo speakers installed externally on a flexible pipe, but in this case, the position of the speaker changes due to external interference, so the direction of the sound changes as well as the risk of damage. have.

The'multimedia type chair' published in Korean Patent Publication No. 1020030088330 also has a speaker installed on the armrest as an exterior, and the'Chair with sound device' published in Korean Patent Registration 2003160130000 and'For computer use' published in Korean Patent Registration 2003027900000 The speaker chair's speaker is not only installed externally, but there is a problem that all sounds are heard only from the rear because two speakers are located at the rear. The “chair equipped with a multimedia headrest” published in Korean Patent Registration 2003249560000 is a two-channel speaker, and it is about a method of reproducing a recording device such as a cassette tape, without the cable 14 being connected from the outside.

The'sound reproducing method and sound reproducing system' published in Korean Patent Application Publication No. 1020060117256 is a system for positioning the woofer speaker 78 at a short distance and is a chair used in a fixed place without moving. An example in which the speaker is mounted on such a fixed chair is the'chair for a game console' published in Korean Patent Laid-Open Publication No. 1019950702135, and the'chair massage device with a multi-channel sound system and a control method thereof' published in Korean Patent Application Publication No. 1020160044631. An example of the'sound audio chair', which is a semi-closed egg-shaped chair, is published in US 20110051962A1.

In addition, there was a case of presenting a wireless speaker as a solution to the external connection sound cable. The'chair headrest with a Bluetooth receiving module and a speaker module' published in Korean Patent Registration 1014777090000 has a problem that the wireless speaker or battery needs to be periodically replaced, and above all, only two speakers are arranged in the rear so that the sound can be heard from behind. There is a problem. In addition, there is no description of the'chair with wireless speaker' published in Korean Patent Application Publication No. 2020080001703, which is a wireless speaker using any method (recognition of Blood or Wifi), and there is no content on power supply essential for driving the wireless speaker.

In addition, in the present invention, since the speaker is installed not only in the front, rear, left and right, but also in the top and bottom, the '3D sound reproduction apparatus using virtual speaker technology in a multi-channel speaker environment' published in Korean Patent Publication 1020080031709, and the'vertical direction An apparatus for generating a virtual channel and a function for generating a virtual channel manufactured by the method thereof may be added to the receiver and mounted.

In the case of sound, it is influenced by the position of the speaker, and it is intuitively known that the more the number of speakers is, the more stable various sound sources can be heard, and it has been proven through related research (see Non-Patent Document 1 below). The important thing in the chair is that the speaker should not have any external influence physically, the multi-channel sound from multiple channels is important to the sound quality of the speaker chair, and it is essential to connect a stable external cable (sound cable, power cable (18)). .

In addition, the boundary between a speaker and a display device is disappearing due to the advancement of technology (see Non-Patent Document 2 below). When sound comes out from the display itself, the volume decreases, and speakers installed in other display devices reach the user after being reflected on objects, but the display-type speaker 30 outputs sound from the user's viewing direction (sound straightness), making it clearer. You can hear the sound. First of all, if the display speaker 30 is installed on both sides of the headrest, it can simultaneously perform the role of a side monitor and a speaker, but currently, since there are few products with speakers installed on the chair, the display speaker 30 There is no example of attaching it to a chair.

In general, since the source device 32 for driving the multi-channel speaker is expensive, it is difficult for a user to configure the multi-channel speaker, so related research is mainly focused on the virtual channel from two speakers. However, if the channel processing device 17 or the like is installed in a speaker chair having multiple channels, a multi-channel speaker can be constructed at a relatively low cost. In this chair, since the power cable 18 is directly connected to the chair, it is possible to install the channel processing device 17 on the chair with reference to the audio system and its control method published in Korean Patent Registration No. 1017450190000.

The 5.1 channel sound chair'published in Korean Patent Application Publication No. 1020130037104' is not a moving chair, and there is no cable connected from the outside, and the 5.1 channel sound must have amplification of sound and channel separation from a receiver, etc., in this invention, the sound source is also in the chair. Since it is described as a structure that connects players such as MP3s, there is a substantial error in the invention, and the purpose and effect of the technology are also different.

Jang Myung Lee, Oh Sang Kwon, Positioning of Automotive Speakers and Audio Performance Evaluation Method, Journal of the Korean Society of Automotive Engineers, Vol. 4, No. 4, pp1~8, 1996. Seongmin Kim, the era of listening to sound without speakers, ChosunBiz, https://biz.chosun.com/site/data/html_dir/2019/10/17/2019101700080.html?utm_source=urlcopy&utm_medium=share&utm_campaign=biz

The present invention is to solve the problems of the conventional technology, and the technical problem of the present invention is that when the speaker is externally installed on a moving chair, the direction of sound is also changed when the "?scent?*" of the speaker changes due to physical interference. The problem of being different, the problem that all sounds are heard only from the rear when the two-channel speaker is located in the rear, the two-channel stereo speaker alone cannot separate and listen to the multi-channel sound source, and a plan to install a multi-channel speaker There was no problem, the center speaker 61 is located in front of the user, so it was difficult to install considering the space inside the chair, the problem that it was difficult to install on the chair because the upper speaker had to be located on the top of the user, In order to solve the problem that it was difficult to install a speaker having a height characteristic on the chair, the problem that auxiliary power means such as batteries were required when installing a wireless speaker on the chair to solve the complexity of the cable 14 connection, one for the three-dimensional effect of sound. The task of providing richer sound to the channel of the woofer 78 is a problem in which the sound goes far and vibrates due to its characteristics, but the user could not selectively operate/stop in the space within the chair, film type 31 or display The type speaker 30 has many advantages, such as a problem that cannot be installed on a chair, and a problem that expensive multi-channel equipment (receiver, etc.) is necessarily required.

The present invention for achieving this object is a chair that has a headrest, a backrest, a seat, and an armrest, a speaker is installed, and a seat support part with wheels that can move in a free direction in a seated state. We present a mobile chair equipped with a multi-channel speaker that installs wired or wireless multi-channel surround speakers up to channels on a moving chair.

The cable 14 mentioned in the present invention is a medium for transmitting an electric signal and includes an acoustic cable, a power cable 18, a display line, a LAN line, an optical cable, an HDMI line, and the like, and the source device 32 is It includes equipment, computers, video equipment, receivers, and Internet equipment. The cable 14 may come out of the chair and be coupled to the outside, or may be connected from the outside to be coupled to the chair.

In the case of multi-channel sound, amplification and channel separation must be performed in an external multi-channel device, so the sound source referred to in the present invention transmits the amplified sound signal from the external multi-channel device to the speaker installed in the chair through the cable 14. It is based on receiving, but if there are exceptions to this matter, a separate explanation will be given.

In the present invention, since the power cable 18 is directly connected to the chair, it is necessary to ensure safety and electric leakage device accordingly. If the electric device is installed on the chair, it must be wrapped with insulation around it, and a cutoff device must be provided to prevent the flow of current above a certain level. An electromagnetic shielding device is also recommended.

Speakers installed on the speaker mounting table of this chair include a speaker unit, a box-type speaker box, a speaker finished product, a film-type speaker 31, a display-type speaker 30, and the like.

In the case of the speaker, when fixing the outer part of the speaker to the speaker mounting table, a material such as rubber is added to prevent the vibration of the speaker from being transmitted directly to the frame, thereby preventing noise caused by the vibration of the speaker.

In the patents related to the chair in which the speaker is mounted on the mobile chair, there are many cases where there is no explanation on how the cable 14 essential for driving the speaker is connected from the outside, and even if there is, a cable connected from the outside due to the nature of the moving chair ( 14) is accompanied by separation and disconnection, but there is no alternative to this, so it was mainly about chairs used in fixed places without moving. When installing an electronic device such as a speaker in such a moving chair, it is essential that the cable 14 must be stably connected without separation or disconnection. Therefore, in the mobile chair equipped with a multi-channel speaker according to the present invention, the cable 14 connection is separately applied to prevent separation or disconnection of the cable 14 even if various cables (sound, display, power cable, etc.) are connected from the outside to the chair. In accordance with the published application number (1020190136008), 2019.10.30 "Movable chair with cable protection device and the protection method of cables connected to the chair".

The channels referred to in the present invention are based on the channel electrical signals independently output, not the number of speakers. If you distribute 3 channels of audio signals and install 30 speakers corresponding to them, it will be a chair equipped with a speaker that outputs 3 channels, and 5 speaker units are installed in each of the 2 speaker boxes and each speaker unit. If you connect a sound cable of an independent channel to the speaker box, it looks like a chair with a speaker that outputs 10 channels.

If the speaker is mounted externally, the speaker is installed on the speaker mounting table to solve the problem of speaker damage or change of direction due to physical interference. For this purpose, the speaker mounting stand is formed in the direction of the inside of the chair, and then the speaker is formed in a curved or straight shape. It includes installing on the speaker mounting table facing the user.

The size of the speaker mount depends on whether the installed speakers are built-in or external, and the number of speakers. It also includes installing a Velcro opening in the center of the rear to facilitate repair in case of speaker failure.

In addition, when a channel change or failure occurs, a speaker mounting table with a speaker is modularized for replacement or expansion of the speaker so that it can be attached and detached, and a combination of the speaker according to the channel change is newly installed on the chair.

A speaker that outputs a selected channel among speakers outputting 32 channels from one channel is mounted on the speaker mounting table. However, since a speaker outputting two channels has a similar invention, it includes a speaker that outputs two channels only when the film type 31 or the display type speaker 30 is mounted. One channel is used when mounting the mono speaker 97. The multi-channel speaker is installed on the speaker mounting table at the positions of the headrest, backrest, armrest, and seat, and is characterized in that it is installed in the up and down positions as well as the front and rear, left and right. The position of the speaker referred to in the present invention refers to a typical example with reference to an audio device (computer or receiver, etc.) channel, but this is for illustrative purposes only, not an absolute position, and various speakers corresponding to each channel It is revealed that the combination is free and includes all. The characteristics of the channels vary by audio device manufacturer, and even if a receiver from the same manufacturer is used, various speaker arrangement options are provided. For example, in the case of Denon's'' receiver, there are 7 speaker arrangement options corresponding to 9.1 channels. For the same reason, the Front Left Speaker is usually installed on the front left side, but the Front Left Speaker may be installed in the normal Side Left Speaker position, and includes installation on the front left side of the lower seat. Even with the same number of channels, the characteristics of the channels (front, rear, left, right, top and bottom) may be different, and speaker arrangements corresponding to the number of channels include various combinations. For example, in general, a 5-channel receiver provides a sound source suitable for a center speaker-front left speaker-rear left speaker-rear right speaker-front right speaker, but the 5-channel speaker presented in the present invention is not only the above example but also the center speaker. -Side left speaker-Rear left speaker-Rear right speaker-Side right speaker, Side left speaker-Rear left speaker-Rear center speaker-Rear right speaker-Side right speaker, Center speaker-Front left speaker-Side left speaker-Side right Includes all the number of positions that can be combined with 5 speakers corresponding to 5 channels such as speaker-front right speaker.

In addition, it is recommended that at least one pair of speakers is placed in a straight line with the user's ear at the shortest distance to obtain a rich sound effect similar to a binaural sound.

The means for coupling the speaker to the speaker mounting stand include screw coupling, adhesive coupling, fitting coupling, Velcro coupling, magnet coupling, groove to rail coupling, groove to protrusion coupling, and pressure coupling by elastic substances (ex. spring), etc. .

Speakers are preferably built-in to minimize external influences, but in order to allow the user to change the direction or position of the speaker in the desired direction, and to mount the speaker on a mobile chair that does not have a speaker already installed, the head It includes externally mounting the left and right speaker mounting tables 40 and 41 of the rest, and installing multi-channel speakers on one side of the left and right speaker mounting tables 40 and 41 as an exterior.

And among the speakers outputting multiple channels, a speaker can be installed outside the chair. For example, if the center speaker is installed outside the chair among speakers outputting 5 channels, and the remaining 4 channels are installed on the chair, , This would be a chair equipped with a speaker that outputs 4 channels.

Compared with the existing speaker chairs with speakers arranged only at the rear or equipped with a 2-channel stereo speaker, the present invention has a multi-channel speaker on the speaker mounting stand formed in the inward direction, so that it is closer to the user compared to the sound output only from the rear. In addition to being outputted from a distance, it is possible to output up and down in addition to the front and rear, left and right for each channel, so that the purpose or effect is completely different compared to the prior art.

The headrest left and right speaker mounting brackets 40 and 41 installed on one side of the headrest include a pair of left and right pairs formed in a straight line or curved in the direction of the inside of the chair to install a speaker. A speaker that is difficult to install in a curved shape, such as a film type 31 and a display type speaker 30, is mainly installed on the straight speaker mounting table, and the film type 31 and the display type speaker 30 are provided on the curved speaker mounting table. Including a general speaker, this is because the multi-channel speaker can be mounted by maintaining a constant distance between the user and the speaker only when it has a curved shape. The headrest speaker installation stand may be directly coupled with the headrest portion, the backrest portion 31, the armrest portion, and the seat portion of the chair, or may be coupled through an extension structure. This includes installing the extension structure on the outside of the rear of the armrest part, attaching the headrest speaker mounting stand at one end, and installing the speaker on the extension structure, and installing the speaker in a vertical direction at the position of the user's ear. .

In addition, since the height of the headrest must be adjusted according to the user's physical condition, the headrest speaker mounting base has a height adjustment device, and the length of the speaker cable is adjusted to the maximum value of the height device, and a combination method that can withstand the load of the speaker and be fixed. To fix. You can refer to the height enhancement device of the bicycle saddle. The coupling part of the headrest speaker mounting table is composed of an oval or an angled shape (right angle, rhombus, etc.) so that the left and right distance between the speaker installed on the headrest part and the occupant remain constant without shaking. In addition, a speaker protection structure is installed on the front of the speaker to prevent damage to the head of the occupant or physical damage to the speaker by the head, and a Velcro opening in the center of the rear of the speaker to facilitate replacement in case of speaker failure. Is to install.

In this portable chair equipped with multi-channel speakers, a movable microphone 28 is installed on one side of the headrest for interactive communication between gamers. A microphone mounting plate 27 attached to one side of the left or right speaker mounting table of the headrest, a microphone receiving part 23 coupled to the microphone mounting plate 27, the microphone mounting plate 27 and a microphone receiving part 23 A coupling means for coupling; And the microphone receiving part 23 accommodates the microphone cable 24 connected from the left or right speaker mounting table 40, 41 of the headrest on one side and a microphone formed of a flexible material on the other side It includes a microphone 28 that is equipped with 28 so as to be able to move the axis. Since the seated person has various physical conditions and the sitting posture is also different, the position of the mouth becomes very diverse, so the position of the microphone 28 cannot be specified. Since the length of the existing fixed flexible microphone 28 is fixed even if it is bent up, down, left and right, it may be insufficient or remain in the optimal position desired by the occupant. On the other hand, if rails are installed at the bottom of the headrest speaker mounting table and installed on one side of the headrest so that the axial position of the microphone receiving part 23 can be changed by the method of sliding coupling, the seat is close to the optimal position desired by the occupant. Thus, the microphone 28 can be positioned.

If you install the headrest upper speaker mounting bracket (42, 43, 44) on the headrest top, and install the center speaker and the speaker output from the top to the headrest upper speaker mounting bracket (42, 43, 44), all multi-channel Since the speaker is installed in the space inside the chair, the user does not need to install a separate speaker (center speaker, etc.) outside, so that a multi-channel sound source can be conveniently used. And since the speaker output from the top can be mounted only when there is a speaker mounting stand at the top, all 32 speakers including the speaker in charge of the top are mounted on the chair.

The upper speaker mounting brackets 42, 43, and 44 of the headrest are folded in the upper direction by placing a hinge device at a portion that is coupled to the chair to facilitate user access and seating, and a plurality of speaker mounting brackets above the headrest can be installed. In a general home environment, it is difficult to install a speaker on the ceiling, so an indirect channel method is used that reflects sound to the ceiling like a Dolvietomos speaker, but this chair has the advantage of outputting a direct channel from the top. However, you can increase the height of the left and right headrest speaker mounting tables and install speakers that are output from the top at the top, and you can also install a dome-shaped speaker mounting stand on the headrest.

Since the sound source of the multi-channel speaker can support sound from the front, rear, left and right as well as from the up and down directions, the backrest speaker mounting stand (45, 46), the armrest speaker mounting stand (47, 48), seat It includes installing a speaker on the speaker mounting table (49, 50).

Armrest speaker mounting brackets (47, 48) may be made of an open structure, but it is good to make a closed-type structure that is easy to install the speaker and is resistant to external shock.

In order to solve the difficulty of connecting the cable 14, a multi-channel speaker is also mounted as a wireless speaker 98. The method of the wireless speaker 98 is Apple's Airplay, a method of receiving audio signals through Wi-Fi radio waves, a Li-Fi method, a communication method using the wavelength of light 36 such as LEDs, and DECT (a short-range wireless communication method). Digital Enhanced Cordless Telecommunications) and WiSA (Wireless Speaker & Audio) authentication type wireless speaker 98 is mounted.

When the wireless speaker 98 is mounted on the speaker mounting table, the power cable 18 is directly connected to the speaker instead of the sound cable, so compared to the conventional prior art (a chair with wireless Bluetooth), a battery is not required. And the effect is completely different.

In general, each wireless speaker 98 connection method is, in all cases, when the speaker is turned on, the Airplay method is to tap the Airplay icon on the Apple terminal, then select the speaker to play the audio being played. The method is to run the software (app) and select a speaker as the connection device. In the Li-Fi method, an external Li-Fi light source 34 illuminates the Li-Fi receiver 35 in the chair. The DECT method is paired by turning on the DECT dongle or DECT controller, and the WiSA method is automatically paired by inserting the WiSA dongle into the computer or turning on the power of the WiSA transmitter. A wireless signal processing device 20 for receiving and distributing the wireless signal 19, such as the DECT dongle or the DECT controller and the WiSA dongle or WiSA transmitter, may be installed on the chair. The wireless signal processing device 20 may be configured separately and installed on a chair, or includes a speaker and installed integrally.

It includes distributing and installing a speaker in charge of one channel to a plurality of speakers. That is, one speaker can output the same audio signal by distributing it to two or more speakers with a Y-shaped gender, etc. at the rear of the audio device. For example, a front left speaker normally outputs a signal of a front left channel from one speaker, but in the present invention, the present invention includes distributing a plurality of corresponding channel speakers and outputting a signal of the front left channel from two or more speakers. . The effect of distributing speakers in this way is to obtain a richer sound effect by installing one speaker of the same channel on the headrest and the other on the armrest, and at the same time, an audio device (computer or When replacing with a receiver, etc.), you only need to connect the sound cable of the new channel to the sound cable of the speaker without installing additional speakers.

Usually, the source device 32 is external, but in the present invention, among the various functions of the source device 32, a channel processing device 17 having only functions essential for driving a multi-channel speaker is installed on one side of the chair. For example, among the functions of the receiver, the channel processing device 17, which has an additional role of receiving, amplifying, separating, and distributing signals, as well as creating a virtual channel, and separating sound and video signals for the display-type speaker 30, is a chair. If installed in, it will be possible to drive multi-channel speakers by direct coupling with a computer, etc., even without receiver equipment.

In the past, since a large number of speakers could not be installed in homes or chairs, multi-channel sound signals were converted into binaural signals, or virtual channel signals having a virtual 3D sound field were output through stereo speakers. Since the channel speaker is mounted on the chair, if the temporary channel generating device is installed in the source device 32 or the channel processing device 17, the low-channel electrical signal is processed by software (level difference, sound image difference, time difference, etc.). Correction), rendering a multi-channel electrical signal, and outputting it to a speaker corresponding to the channel. The channels exemplified in the present invention illustrate up to 32 channels, but the technical concept includes more. For example, according to the MADI (Multichannel Audio Digital Interface) standard, a sampling frequency of 96 KHz is set to 128 channels with one cable 14. Although transmission is possible, there is a limit to physically installing a large number of speakers in a limited space called a chair. However, in the present invention, since the cable 14 including the power cable 18 is connected to the chair, the channel processing device 17 is installed on the chair, and a plurality of virtual channels are added in an actual channel to effect two or more channels. As can be seen, if 32 virtual channels are added to the 32 channel speaker output by receiving the audio electrical signals of the independent 32 channels of the present invention, this will be referred to as a chair having the effect of 64 channels on the 32 channel speaker chair, If n virtual channels having the effect of a plurality of channels are applied in one channel, it will be referred to as a chair having the effect of n channels even though it is a 1-channel chair. Such a virtual channel effect may be mounted on a chair in addition to the function of the channel processing apparatus 17.

A woofer speaker 78 may be installed on the backrest part 31, and the woofer speaker 78 is a woofer speaker control device 29 that can be turned on and off because sound may be transmitted to the outside together with vibration due to the characteristics of the low-pass speaker. Is installed on one side of the chair. Sub-speakers (ex. woofer speaker 78, etc.) are included in the speaker having 1 channel or more and 32 channels or less of the present invention, and when sub-speakers are installed, the number of channels is indicated by a decimal point. For example, when the woofer speaker 78 is installed in a 5-channel speaker, it is displayed as 5.1 channels. In general, one woofer speaker 78 is mounted, but two or more may be mounted for enhanced bass sound. If two woofer speakers 78 are installed in a 5-channel speaker, it becomes 5.2 channels.

Since the woofer speaker 78 installed on the backrest part 31 may generate vibration, it should be noted that it is fixed more than other speakers. In order to reduce vibration, a cushioning material such as styrofoam may be installed around the woofer speaker 78, and conversely, it may be installed without a cushioning material to emphasize vibration. Since the woofer speaker 78 is installed on the backrest part 31 that directly receives the load of the seated person, it is mounted inside the backrest part 31 without opening the front of the speaker. Then, the sound direction of the woofer speaker 78 is directed toward the seated person, and a woofer speaker control device 29 is installed on one side of the chair for users who do not want vibration and low-frequency sound sources.

As for the speaker to be installed, a speaker chair including a film type 31 or a display type speaker 30 that can be installed with a small weight and volume in a limited space called a chair is posted. As the film-type speaker 31 is cut, the sound is reproduced over three listening spaces (rear, side, and front) in a rectangular shape, so it can be attached to one side of the chair or a speaker mounting table to produce a three-dimensional sound. In addition, when a diaphragm is installed on the back of the display, and a display-type speaker (ex.Crystal Sound OLED) that produces sound from the display is installed inward on the left and right speaker mounts (40, 41) of the headrest, the dynamic image and sound are output. It provides a new experience.

Due to the display-type speaker 30, the boundary between the display and the speaker is disappearing, and the display-type speaker 30 installed on the left and right speaker mounting tables 40 and 41 of the headrest can simultaneously serve as a side monitor and a speaker. I can. In addition, the display speaker 30 includes a wireless display and a wireless speaker mounted on the chair in a combined form.

A mobile chair equipped with a two-channel speaker has an existing invention, so in the present invention, for novelty and advancement, the film-type 31 or the display-type speaker 30 includes two channels, and 32 in one channel. It includes a mobile chair mounted as a speaker that outputs any one channel selected from among the channels. The reason is that the existing speaker outputs sound at the point (point) where the speaker is installed, whereas the film type 31 or the display type speaker 30 outputs sound at the'side', so the applied effect is completely different. .

Since a large number of speakers are installed on the chair, a pipe for the cable 14, which plays a central role, is installed on one side of the chair to facilitate the detachment and detachment of the cable 14 when necessary. In addition, since a large number of speakers are installed on the speaker installation table, a speaker installation table is made in the form of reinforcing cushioning material in the frame structure in consideration of weight, and speakers are mounted on the frame. In this case, when the speaker is fixed inside the frame, a device that rotates the speaker axis is placed on the upper and lower structures of the frame so that the speaker can be adjusted in the direction the user wants. In addition, if the frame constituting the speaker mounting table is formed in a parallel frame structure, the upper and lower frame structures are in the shape of grooves and rails, and the speaker is mounted, the built-in speaker also includes a position that can be moved to some extent. In addition, Korean Patent Application Publication No. 1020190084883 (2019.01.07) “A method of generating customized spatial audio with a head tracking function” may be applied to this chair.

Since the speaker is mounted close to the user, install a speaker protection structure.

Fix the outside of the chair, the protective net, and the speaker cloth with rubber moldings so that the speaker cloth can be replaced if necessary. The rear of the speaker can be opened with Velcro when the speaker needs to be removed or repaired.

The advantage of this outbreak compared to the conventional technology is that it proposes a method of installing a speaker in a movable chair in a multi-channel manner so that a multi-channel sound source can be heard from the chair, and it is not an external two-channel stereo speaker that was heard only from the rear. , Multi-channel speakers ranging from 1 channel to 32 channels are built into the speaker mounting table to prevent the speaker from changing direction due to external shock, and speakers are placed in the front, rear, left, right and top and bottom inside the chair so that you can hear three-dimensional sound in the space inside the chair. Made it possible. In addition, by installing the upper speaker including the center speaker on the speaker mounting table installed at the top, you can listen to all multi-channel sound sources including the channel output from the top without having to install a speaker outside. And by directly connecting the power to the wireless speaker, which eliminates the disadvantages of the complicated sound cable connection, you can use the wireless speaker without replacing the battery.

In addition, since the speaker is installed in the chair, the distance between the user and the speaker is short, so there is an effect that there is no need to correct the distance of the sound for the multi-channel speaker. Equipped with a woofer speaker control device 29 that can be turned on and off accordingly.

In addition, by installing multiple speakers in one channel, you can hear richer sound than the actual channel, and even when the number of channels increases later, you only need to change the sound cable without installing additional speakers, so expandability is improved. In addition, due to the movable microphone 28, the position of the microphone 28 can be adjusted to suit the user's body shape.

In addition, the film type 31 or the display type speaker 30 is driven by power connected to the chair and installed on the chair, taking advantage of the film type speaker 31 coming out of a wide area, and also using the display type speaker 30 It was proposed to install and perform the functions of the side monitor and speaker at the same time. In addition, instead of not having expensive multi-channel equipment, only the channel processing device 17 is installed on the chair to provide a multi-channel effect at a relatively low cost.
