Description

[Technical Field]

[0001] This invention relates to a device for integrating visual exhibits with sound, and in particular to a technology that provides a new immersive experience that integrates sight and sound by vibrating the acrylic showcase itself to generate sound. [Background technology]

[0002] Conventionally, the mainstream method of adding sound to visual exhibits has been to simply install speakers around or inside the display stand, as in Patent Documents 1 and 2, which simply "adds" sound. However, this method does not provide the experience of the sound source emanating directly from the exhibit, and has the problem of lacking a sense of immersion. Furthermore, within the scope of the applicant's research, there are no existing products on the market that integrate existing showcases with sound functions.

[0003] [Patent Document 1] Jikkai Showa 59-177363 [Patent Document 2] Patent Publication No. 2009-066261 Summary of the Invention [Problem to be solved by the invention]

[0004] This invention does not aim to function as a speaker device, but rather provides an audio playback device that uses the entire exterior case as a speaker, allowing for an immersive experience in which the exhibit and the sound become one. [Means for solving the problem]

[0005] The present invention solves the problem by the following configuration. The sound reproduction device of the present invention comprises a box-shaped outer case, an intermediate panel arranged on the inner surface of the case, and a vibrator arranged inside the intermediate panel. Furthermore, sound-absorbing material is arranged inside the outer case to suppress unnecessary resonance. In addition, a removable cover is provided on the top surface of the outer case, allowing exhibits to be placed inside this cover.

[0006] The intermediate panel and vibrator are respectively disposed on the inner surfaces of the top and opposing side panels of the exterior case. A vibration absorbing member may be further disposed on the top surface of the exterior case, and the cover is disposed on the exterior case via the vibration absorbing member. The exterior case is primarily made of opaque acrylic material, and the cover is made of transparent acrylic material. The intermediate panel is made of a material selected from MDF, plywood, resin plate, and metal plate.

[0007] The transducers are driven by software control means using a predetermined acoustic correction technique, preferably Bongiovi DPS, to improve sound quality and realism.

[0008] Furthermore, lighting means are placed on the top surface or inside the exterior case, and can be controlled to turn the lights on and off in conjunction with software control means. At least one of a Bluetooth (registered trademark) module, audio jack, SD card slot, or USB terminal is provided as sound input means. This allows for a variety of sound inputs, while providing an immersive experience that integrates the exhibit with sound and light effects. [Effects of the Invention]

[0009] This device allows the entire exterior case to function as a speaker, providing an immersive experience where the exhibit and sound output are integrated. Resonance can be controlled by selecting materials and arranging sound-absorbing materials, and high-quality sound and a realistic presentation can be achieved by using specific acoustic correction techniques. [Brief explanation of the drawings]

[0010] [Figure 1]1 is a perspective view of the appearance of a sound reproducing device according to an embodiment of the present invention; [Figure 2] 1 is a front cross-sectional view of an acoustic reproduction device according to an embodiment of the present invention; [Figure 3] 1 is an external view of a sound reproducing device with a cover attached according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0011] An audio playback device (hereinafter referred to as "device 10") according to an embodiment of the present invention will be described. FIG. 1 is a perspective view of device 10. Device 10 includes an exterior case 1 made primarily of acrylic. The exterior case 1 is configured as an opaque box, with a transparent or translucent acrylic cover 4 detachably attached to its top. A portion of cover 4 is releasable, allowing exhibits to be placed in the interior space of cover 4 from the releasable area, making them visible. The overall appearance forms a showcase. While a cubic or rectangular parallelepiped exterior shape is preferred, a box-like shape such as a triangular prism or hexagonal prism is also acceptable. The dimensions of the case can be appropriately set depending on the type of exhibit and the installation environment. Furthermore, the materials for exterior case 1 and cover 4 are not limited to acrylic.

[0012] Figure 2 shows an example of the internal structure of the exterior case 1. Inside the exterior case 1, side panels 2a and 2b and a top panel 2c are arranged as intermediate panels made of MDF panels, plywood, resin boards, or metal plates. These intermediate panels are attached directly to the exterior case 1 or are bonded via an elastic material, and serve to stabilize the resonance characteristics of the entire exterior case 1. Furthermore, if sound-absorbing material is appropriately placed in the space inside the case, unwanted resonance can be reduced. Epoxy adhesive, double-sided adhesive sheets, or screws can be used to secure the panels.

[0013] Each of the intermediate panels 2a to 2c is fitted with one vibrator 3. That is, a total of three vibrators 3 are arranged, one on each of the left and right side panels 2a and 2b and one on the top panel 2c, but this is not limiting and one, two, or four or more vibrators may be arranged. This causes the entire exterior case 1 to vibrate three-dimensionally, enhancing the bass range and widening the sound field.

[0014] Furthermore, the device 10 includes a sound source input means such as Bluetooth, an audio jack, an SD card, or a USB, and drives the vibrator 3 based on an externally input signal. The audio signal is controlled using software control means including Bongiovi DPS audio correction technology, which can improve sound quality and realism. The audio correction technology is not limited to Bongiovi DPS, and various other audio correction technologies can be applied.

[0015] Figure 3 shows the external view of the device 10 with the removable cover 4. The cover 4 is made of a transparent or translucent material, allowing the exhibits to be seen and also serving as a resonator for the device 10. When the cover 4 is removed, an open and clear sound is obtained, making it suitable for music playback and background music applications. On the other hand, when the cover 4 is attached, the reflections within the case enhance the realistic sound, and when a character is placed as an exhibit, it provides an effect suitable for playing character lines or readings. Furthermore, a vibration-absorbing member can be attached to the top or bottom of the exterior case 1, thereby protecting the exhibits and ensuring structural stability. When the vibration-absorbing member 5 is placed on the top of the exterior case 1, the case 4 is placed on top of the vibration-absorbing member 5. In addition, various switches such as push buttons are provided on the front operation section of the exterior case 1, and an LED unit 6 is attached to the top or inside of the exterior case 1 to illuminate the exhibits placed inside the case 4. When the LED unit 6 is placed inside the exterior case 1, light leaking through notches and slits formed on the top and sides of the case can be enjoyed. In this case, it is possible to control the ON / OFF of the LED unit 6 by operating the push button. Furthermore, the LED effect may be controlled in conjunction with software control. While Fig. 3 shows an example in which vibration absorbing members 5 are placed at the four corners of the top surface of the exterior case 1 and LED units 6 are placed on a pair of opposing sides, the present invention is not limited to this configuration.

[0016] The distinctive feature of this device 10 is that the entire exterior case functions as a sound source, combining upward radiation through the top panel and expansion from the sides, spatially integrating the exhibit and the sound output, giving the user a sense of immersion as if the exhibit were making a sound.

[0017] Compared to conventional devices that simply install speakers around or inside the exhibition stand, this device 10 allows the case itself to function as a sound source, improving the aesthetics and sense of unity of the exhibition space. Also, because there is no need to install external speakers, there is more freedom in installation location, making it easy to use in small spaces or multiple exhibition spaces.

[0018] Furthermore, because the device 10 emits sound from the entire case using the vibrators 3 installed in three locations, it can achieve a three-dimensional and expansive sound field compared to conventional transparent cases and small speakers. It is particularly excellent in reproducing low-frequency sounds, providing a sense of depth that cannot be achieved with a transparent acrylic case alone.

[0019] This device 10 functions not only as a sound output device but also as part of the exhibition presentation, further enhancing the appeal of exhibited items such as character figurines, models, crafts, jewelry, etc. By providing the experience of the exhibited items making sounds, it can provide a high level of satisfaction to both the exhibitors and the viewers. [Industrial Applicability] This device can be widely used as an experiential display device in the hobby market for anime, games, figures, etc., as a promotional device for store exhibitions, or as an audio device for interior use. It provides high added value, especially in fields that emphasize immersive experiences that integrate visual content and audio.
