Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a seated speaker. Background Technology

[0002] Traditional two-channel stereo speakers placed facing the front can achieve a sound field effect mainly from the horizontal plane, such as... Figure 5 When listening to traditional stereo speakers, one typically needs to be positioned at one vertex of an equilateral triangle to achieve the best effect (commonly known as the "sweet spot"). At this position, the time difference and intensity difference between the sound waves from the left and right channels reaching both ears are most effectively processed by the brain (refer to the de Boer effect). However, in real life, listening positions are more arbitrary, and environments are rarely symmetrical, resulting in inconsistent reflection intensities on both sides. Furthermore, the two speakers may not be precisely positioned, all of which negatively impact the stereo sound field experience.

[0003] Furthermore, traditional two-channel speaker enclosures, with one on each side placed directly in front of the listener, require additional space, including the space occupied by the chair and an unobstructed listening area to approximate an equilateral triangle. For example, an equilateral triangle with a speaker spacing of 2 meters occupies an area of ​​approximately 1.7 square meters, but in reality, it often requires more than 4 square meters of space. People moving around in this area and large objects placed there will block or reflect the sound. As a result, these traditional two-channel stereo speakers have gradually faded out of use in modern homes, replaced by small and flexible Bluetooth speakers that produce sound but lack a sound field.

[0004] In addition, such as Figure 6 Traditional speakers require the height of the human ear and the height of the speaker to be as consistent as possible in order to obtain the sound from the horizontal center of the axial-emitting speaker and form the most effective sound field experience. However, because a speaker has two units, a tweeter and a woofer, or even three units, such as a midrange unit, the vertically arranged speakers cannot obtain the sound from the shortest distance between the human ear and the horizontal center of each speaker. This means that the sound at a different height than the ear has been attenuated by the time it reaches the ear. It also means that different frequencies of sound emitted from the speaker at the same time reach the human ear at different times, resulting in auditory errors.

[0005] Popular portable Bluetooth speakers today, such as Figure 7 Even with a two-channel stereo design, the distance between the human ear and the Bluetooth speaker (1-5 meters) is much greater than the distance between the left and right channel speakers on the Bluetooth speaker (10-20cm), resulting in the loss of the optimal listening position. This size difference of more than 10 times leads to the loss of stereo sound. In fact, the playback effect of a small Bluetooth stereo speaker is just like that of a mono speaker.

[0006] This application is filed to address the aforementioned deficiencies. Utility Model Content

[0007] The purpose of this invention is to provide a seated speaker that horizontally embeds two sets of speaker groups into a stool to achieve optimal stereo sound field positioning. This solves the problem of large footprint of traditional two-channel separate speaker cabinets, as well as the problem of poor stereo sound field experience of traditional two-channel separate speaker cabinets and portable Bluetooth speakers.

[0008] To address the aforementioned issues, this utility model provides a seated speaker, comprising a seat body and speaker modules. The seat body has a seating area where a user can sit. At least two sets of speaker modules are provided, both mounted on the seat body and symmetrically distributed on both sides of the seating area. The speaker modules emit sound vertically upwards, creating a rotating sound field compared to the direct frontal sound of traditional speakers. The sound heard is identical, but the sound fields formed when the left and right channels overlap are completely different. This is an unprecedented sound field experience, and the best stereo effect can be obtained simply by sitting in the seating area, meaning the "sweet spot" is clearly attainable.

[0009] According to one embodiment of this utility model, the speaker module includes a midrange speaker and a tweeter. The midrange speaker and tweeter are coaxially and collinearly arranged with the seat. The axes of all the speakers arranged in a horizontal line are aligned with the ear of the person sitting in the seat, achieving a more precise and minimally attenuated sound experience (see...). Figure 4 This solves the sound attenuation problem caused by traditional vertical arrangement methods.

[0010] Alternatively, the high, mid, and low frequency speakers can be replaced by a full-range speaker.

[0011] According to one embodiment of the present invention, the main body of the seat includes a lower shell and an upper shell, and the speaker module is installed between the lower shell and the upper shell for easy installation. Other optional methods include drilling installation.

[0012] According to one embodiment of the present invention, the top of the speaker module is lower than, higher than or flush with the plane of the seat portion.

[0013] According to one embodiment of the present invention, the main body of the seat is provided with a speaker grille for covering the speaker module, which is used to protect the speaker module. Preferably, the speaker grille is made of materials such as bamboo weaving, fabric, or coarse fiber paper, which can ensure the sound output effect.

[0014] According to one embodiment of the present invention, a capacitive human body sensor is provided at the seat position, or a pressure sensor, infrared sensor, etc., can also be used to detect whether the user has sat down at the seat position. The human body sensor is electrically connected to the circuit module that drives the speaker.

[0015] Optionally, the seat may be provided with a positioning structure, such as color or line markings, or a conspicuous structure such as a groove, so that the user can easily and quickly locate the exact position of the seat, i.e., the emperor's seat.

[0016] According to one embodiment of the present invention, the main body of the seating is a bench, chair, polyhedral structure, or other structure capable of realizing the function of seating.

[0017] According to one embodiment of this utility model, the seat is a board with short legs. The length of the legs can be flexibly adjusted according to the design. Considering ground reflection and practical application, the leg length is between 10-60cm.

[0018] According to one embodiment of the present invention, the main body of the seat is made of glass, stone, wood, metal or polymer material.

[0019] According to one embodiment of the present invention, the distance between the two sets of speaker modules is ≥50cm.

[0020] According to one embodiment of this utility model, a low-frequency module is installed at the bottom of the seat body. The low-frequency module includes a subwoofer or a passive low-frequency radiator. The low-frequency module is positioned facing the ground. The subwoofer or passive low-frequency radiator projects bass frequencies towards the ground and then reflects them back up to the ear, creating a stronger sense of low-frequency immersion. Because the human ear has a weak sense of directionality for low frequencies, they can reach the ear through reflection. However, the human ear is sensitive to the directionality of mid- and high-frequency frequencies, so they cannot be reflected back to the ear, otherwise it will affect the formation and quality of the sound field.

[0021] The beneficial effects of this invention are that by setting a vertically upward-emitting speaker module on the main body of the seat, a 90-degree rotating sound field is formed compared with the traditional speaker that emits sound directly in front of the user. The sound heard on both sides is exactly the same, and the distance between the speakers of the left and right channels and the ears of the person in the middle is the same. This allows the sound intensity and sound wave arrival time of the left and right channels to be consistent, thus easily forming a significant sound field effect. Moreover, because the speakers emit sound vertically upward, what the user hears is a 90-degree rotating sound field effect, which is equivalent to rotating the orchestra that was originally in front of them to directly below them, thus obtaining a completely new sound field imaging experience. This rotating sound field experience is particularly strong when listening to electronic music. In addition, the speakers on the seated speaker can be arranged horizontally in a straight line, so that the axis of all speakers can be aligned with the ear of the person sitting in the seat, resulting in more accurate and minimal sound attenuation and a high sound pressure level immersive sound field experience. Furthermore, the seated speaker of this solution occupies a much smaller area than the actual area of ​​a traditional two-channel stereo speaker. When using a seated speaker with a height of 60cm to 120cm, its area is only 0.2 to 0.4 square meters, which is much smaller than the actual area of ​​a traditional two-channel speaker.

[0031] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0032] A type of seated speaker, such as Figures 1-4 It includes a seating body 101 and a speaker module 102.

[0033] The seating body 101 can be a bench, a board with short legs, a chair, or a multifaceted structure—any structure capable of providing seating. In this embodiment, the seating body 101 is a wooden bench. When using a 60cm-120cm seated speaker, its footprint is only 0.2-0.4 square meters, far smaller than the actual footprint of a traditional two-channel speaker. Achieving a similar or superior sound field immersion effect to traditional two-channel speakers with a smaller footprint is an advantage of this patent.

[0034] When choosing a seating arrangement with short legs, the leg length can be flexibly adjusted according to the design. Considering ground reflection and practical application, the leg length is between 10-60cm.

[0035] The main body 101 of the seat is provided with a seat part 103, where the user can sit. At least two sets of speaker modules 102 are provided, both of which are provided on the main body 101 of the seat and are symmetrically distributed on both sides of the seat part 103. The distance between the two sets of speaker modules 102 is generally 50cm to 80cm, so as to form an equilateral triangle with the human ear.

[0036] Each speaker module 102 generally includes a tweeter and a woofer. The midrange and tweeter are coaxially and collinearly arranged with the seat 103. All the speaker axes, arranged in a horizontal line, are aligned with the ears of the person in the seat, achieving a more precise and minimally attenuated sound experience. If one full-range speaker is used per channel, they should also be arranged in a straight line with the person's ears: "left speaker - left ear - right ear - right speaker".

[0037] The seat body 101 includes a lower shell and an upper shell, and the speaker module 102 is installed between the lower shell and the upper shell, making installation convenient and quick.

[0038] The seating body 101 is provided with a speaker grille to cover the speaker module 102, which is used to protect the speaker module 102. The speaker grille is preferably made of materials such as glass, bamboo weaving, fabric, coarse fiber paper, plastic or metal mesh, which can ensure the sound output effect and protect the speaker from accidental damage. The speaker grille can be optionally set as a component of the speaker module 102.

[0039] Optionally, the top of the speaker module 102 may be lower than, higher than, or flush with the plane of the seat portion 103. In this embodiment, for example... Figure 1 , Figure 2 The speaker module 102 is installed in the seat section 103 with its top lower than the plane of the seat section 103.

[0040] The speaker module 102 emits sound vertically upwards, creating a 90-degree rotating sound field compared to the frontal sound emission of traditional speakers. Although the sound emitted by each speaker remains the same, the sound fields formed by the left and right channels are completely different, providing an unprecedented sound field experience. Figure 2 , Figure 4 The listener can obtain the best stereo effect by sitting directly at seat 103. At this time, the distance between the left and right channel speakers of the seated speaker and the ear of the person in the middle is the same, which can make the sound intensity and sound wave arrival time of the left and right channels consistent, thus easily forming a sound field effect (refer to the de Boer effect).

[0041] A capacitive human body sensor is installed at the seat 103 position. Alternatively, a pressure sensor or infrared sensor may be used to detect whether the user has sat on the seat 103. The human body sensor is electrically connected to the speaker module 102. When the sensor detects that the user is sitting on the seat 103, it sends a start command to the speaker module 102, and the speaker module 102 emits sound.

[0042] Based on the actual listening experience of this device, the appropriate power of the speaker and amplifier should be greater than 20W, with sufficient output to obtain sufficient sound pressure.

[0043] Considering the speaker's proximity to the user and the size of the device, the appropriate size for the speaker should be within 5 inches.

[0044] This device can be powered by external mains power, battery power, or solar power.

[0045] Optionally, a positioning structure is provided at the seat part 103, such as color or line markings, or a conspicuous structure such as a groove, so that the user can easily and quickly locate the accurate position of the seat part 103.

[0046] Preferably, such as Figure 8 A low-frequency module 104 is installed at the bottom of the seat body 101, such as on the side of the seat 103 facing the ground. The low-frequency module 104 includes a subwoofer or a passive low-frequency radiator. The low-frequency module 104 is set facing the ground. The subwoofer or passive low-frequency radiator projects bass frequencies toward the ground and then reflects them back to the ear, creating a stronger sense of low-frequency immersion.

[0047] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
