Description

Technical Field

[0001] The present invention relates to a speaker, in particular to a high-fidelity speaker. Background Art

[0002] In the past, hi-fi speakers were typically designed with very large cabinets to reproduce lower frequencies. Most high-fidelity speakers were floor-standing. Due to the large size of the woofers, the front panels were also wide, making them unsuitable for use in small spaces. Their main structures can be divided into the following three basic types.

[0003] ① Closed speakers: see Figure 1 It utilizes a large enclosed cavity and a large woofer to match the overall resonant frequency and quality factor of the cabinet and woofer. The frequency response range of the speaker is above the woofer's resonant frequency. This design easily achieves high amplitude-frequency and phase-frequency responses within the effective frequency response range. Its main disadvantages are: the large woofer and resulting large cabinet result in a large overall size and high cost; the woofer often reproduces both mid-range and bass simultaneously, causing the mid-range to be severely modulated by the bass, significantly affecting resolution.

[0004] ② Inverted speaker: see Figure 2 When the resonance frequency of the cabinet itself is limited to a certain extent, it uses the lower resonance frequency of the bass reflex tube to superimpose the anti-phase vibration part behind the speaker with the positive phase vibration, so as to achieve the effect of improving the low-frequency amplitude response, thereby extending the lower limit of the overall frequency response of the speaker. Compared with closed speakers, it can achieve a smaller overall volume and a smaller diaphragm area on the basis of the same frequency response range, which reduces the cost to a certain extent. The disadvantage of the bass reflex speaker is that since the compensation of the low-frequency response uses the anti-phase sound field, the phase frequency response will have a phase jump in the low-frequency range, affecting the low-frequency clarity and transient response capability.

[0005] ③ Transmission line (maze) speaker: see Figure 3 , it uses the structure of the cabinet itself to construct a sound wave phase delay inside the cabinet, so that the anti-phase sound waves passing through this phase delay form constructive interference with the positive phase sound waves at a series of specific frequencies, thereby compensating for the insufficient low-frequency frequency response of the speaker and the cabinet itself. This design is usually used in scenarios where: the speaker itself has insufficient downward extension and there are high requirements for low-frequency frequency response; or the lower edge of the frequency response required by the design is too low, making the design of the speaker itself and the cabinet difficult, and corresponding reinforcement far below the resonant frequency is required. This structure usually has a comb-shaped uneven frequency response when reproducing in the low-frequency band, and the phase delay itself will also introduce time delay, resulting in poor low-frequency transient response.

[0006] The fundamental reason for adopting these design approaches in the past is that, due to limitations in materials and other factors, the performance of the speakers themselves was limited, making it difficult to achieve a subwoofer with satisfactory performance across all aspects. Therefore, the enclosure was used to compensate for the speaker unit's performance deficiencies and achieve overall design targets. In summary, existing high-fidelity speaker designs, designed to increase low-frequency reach, also introduce a certain degree of distortion. Furthermore, the enclosure structure is relatively complex, bulky, and expensive, impacting the user experience, leaving room for improvement. Summary of the Invention

[0007] The purpose of the present invention is to provide a new type of high-fidelity speaker with better bass dive, better sound image positioning, better resolution and smaller space size, so that it can be flexibly arranged in locations such as desktops and TV cabinets.

[0008] Therefore, the present invention provides a new type of high-fidelity speaker, which includes an outer wall of the box, a front baffle and a side baffle, wherein the front baffle and the side baffle are both arranged inside the outer wall of the box, the peripheral edge of the side baffle abuts the inner surface of the outer wall of the box, one side edge of the front baffle abuts the side baffle, and the remaining edge of the front baffle abuts the inner surface of the outer wall of the box, thereby dividing the internal space of the box surrounded by the outer wall of the box into three chambers, namely, the mid-high frequency chamber, the bass chamber and the sound guide chamber, and one side of the side baffle is the sound guide chamber, and the other side of the side baffle is A mid-high frequency cavity and a bass cavity, wherein at least two openings are provided on the outer wall portion of the box body corresponding to the mid-high frequency cavity, namely a tweeter port and at least one mid-range speaker port, so as to respectively install a mid-range speaker and a tweeter; a bass sound guide port is provided on the outer wall portion of the box body corresponding to the sound guide cavity, and the bass sound guide port is adjacent to the at least two openings distributed on both sides of the side partition; and a bass port is provided on the portion of the side partition corresponding to the bass cavity, so as to install a bass speaker facing the sound guide cavity, and the bass cavity forms a closed cavity.

[0009] As a preferred embodiment, the bass cavity, the sound guide cavity and the bass speaker installed on the side partition between the bass cavity and the sound guide cavity form a bass unit, and the output opening direction of the sound guide cavity is at a right angle, an acute angle or an obtuse angle to the axis of the speaker.

[0010] As a preferred embodiment, the outer wall of the box includes a front panel, a rear panel, a left panel, a right panel, a top panel and a bottom panel, and the mid-range speaker port, the tweeter speaker port and the bass sound guide port are all arranged on the front panel.

[0011] As a preferred embodiment, the top view of the outer wall of the box is: a rectangle in which the front panel and the rear panel are parallel to each other and the left panel and the right panel are parallel to each other, a right-angled trapezoid in which the front panel and the rear panel are parallel to each other, or a trapezoid in which the front panel and the left panel and the right panel are all at obtuse angles.

[0012] As a preferred embodiment, the widths of the left side panel and the right side panel are at least 1.5 times the width of the front panel, forming a narrow structure of the front panel.

[0013] As a preferred embodiment, the widths of the left side panel and the right side panel are at least twice the width of the front panel, forming a narrow structure of the front panel.

[0014] As a preferred embodiment, the width of the bass sound guide port is the same as the gap between the side partition plate and the left side plate.

[0015] As a preferred embodiment, the front and rear lengths of the side partitions are consistent with the internal length of the outer wall of the box body, and the height is consistent with the internal height of the outer wall of the box body. The width of the front partition is the same as the distance between the outer wall of the box body and the side partitions, and the height is consistent with the internal height of the outer wall of the box body.

[0016] As a preferred embodiment, the mid-high frequency cavity is a closed cavity.

[0017] As a preferred embodiment, the bass sound guide opening is arranged in the front of the speaker, and is in the shape of a flat rectangle with a short side size of 0.5 cm to 10 cm and a long side size of 5 cm to 100 cm.

[0018] Preferably, the width and height of the mid-high-frequency and bass cavities are minimized while meeting the size and caliber requirements of the woofer and mid-range speakers, respectively. The front-to-back dimensions of the mid-high-frequency and bass cavities are based on the compliance volume requirements of the woofer and mid-range speakers, respectively. The width of the sound guide cavity is reduced without hindering the vibration of the woofer. Preferably, the outer wall portion of the box corresponding to the mid-high-frequency cavity is vertically opened with an opening for the mid-range speaker, a tweeter speaker, and a mid-range speaker.

[0019] In the present application, installing the woofer toward the sound guide cavity means that the woofer faces the sound guide cavity, that is, the diaphragm of the woofer transmits sound waves in a manner of facing the sound guide cavity.

[0020] With the development of science and technology, the performance of bass playback units has been greatly improved, and its cost has also been greatly reduced. It is no longer necessary to use complex and bulky cabinets to make up for the shortcomings of bass playback. The present invention can adopt the following concept: two sealed hollow cavities arranged front and back are set in the cabinet, serving as a bass cavity and a mid-high frequency cavity respectively, wherein the bass cavity is located behind the mid-high frequency cavity; the width and height dimensions of the two cavities are minimum when they meet the size and caliber requirements of the bass and mid-range speakers respectively, and the front and back dimensions are based on the compliance volume requirements of the bass and mid-range speakers respectively. The third cavity, the sound guide cavity, is adjacent to the bass cavity, and a woofer hole is set on the partition shared by the guide cavity and the bass cavity, and the sound guide cavity opens forward to serve as a sound guide tube. Midrange and tweeter holes are provided on the front panel corresponding to the mid-high frequency cavity.

[0021] To enhance bass playback quality and achieve a relatively low frequency threshold, many existing speaker solutions employ methods such as directing, delaying, or otherwise processing the back-propagating sound waves from the speaker, superimposing them on the forward-propagating sound waves. This approach aims to achieve higher decibel levels (louder) in the low-frequency range. However, this compromises fidelity. Because two distinct waves are superimposed, fidelity suffers, introducing artifacts, a significant drawback for high-fidelity sound. Whether directing or delaying, perfect delay or superposition is impossible. While existing speaker technology can achieve relatively good low-frequency response, this is insufficient for achieving high fidelity. To address this issue, the present invention first shields the back-propagating sound waves from the speaker, preventing them from interfering. This approach utilizes a sealed woofer chamber. Furthermore, to address this issue, a sound guide tube (i.e., a sound guide chamber) is added in front of the woofer, improving playback efficiency and enhancing the frequency response curve. Furthermore, by utilizing only forward-propagating sound waves, high fidelity is ensured. By properly stacking (stacking), the overall volume of the speaker is very small, the speaker is compact, the front face is narrow, and the positioning accuracy of the sound image is very high. The invention realizes the innovative design of the bass band and woofer through a specific structural design, which can achieve high fidelity.

[0022] Through the above arrangement, the woofer is installed from the bass port toward the sound guide cavity (sound guide tube). By reducing the width of the sound guide tube without hindering the vibration of the woofer, the overall width of the speaker cabinet can be made smaller while the woofer receives the desired acoustic load. At the same time, the forward opening of the sound guide tube reduces the loss of bass sound waves propagating in space. The sound guide tube also acts as a low-pass filter for sound waves, making bass playback cleaner and purer. The back sound waves of the mid- and high-frequency speakers are isolated from the back sound waves of the woofer by the front baffle, avoiding the influence of the excessive amplitude of the woofer's back sound waves on the mid- and high-frequency speakers, thereby ensuring the playback fidelity of the mid- and high-frequency sounds.

[0023] In the present invention, the woofer is installed sideways and outputs sound through a sound-conducting tube. The characteristics of the woofer are that the front face of the box is relatively narrow, the sound and image positioning is accurate, the bass playback efficiency is relatively high, and there is no rear bass interference.

[0024] In a specific embodiment, the bass output method is a rectangular sound guide tube. By rationally designing the shape and size of the sound guide tube, the low-frequency playback efficiency can be improved while minimizing the selective attenuation of each frequency to ensure a flat frequency response curve.

[0025] The above design is based on the current development of low-frequency speakers. The performance of the speaker itself can already meet the requirements of use, so there is no need for the design of the cabinet to make too much inclination towards its low-frequency frequency response performance, which can further make certain inclinations towards the overall sound quality and practicality.

[0026] The beneficial effects of the present invention are:

[0027] 1. The common width of the mid-high frequency wall and the bass wall is minimized without hindering the installation of the woofer and mid-high frequency speakers. By appropriately increasing the front-to-back length of the speaker, the bass cavity provides sufficient buffer volume for the low speaker, thereby achieving efficient bass reproduction without additional distortion under the premise of smaller volume and narrower front dimensions.

[0028] 2. The bass cavity and the mid-high frequency cavity are sealed to each other, so that the back sound waves of the woofer will not interfere with the mid-range speaker.

[0029] 3. By dividing the frequency, the mid-range speaker operates above the resonant frequency, which reduces the average phase displacement of the mid-range speaker during playback, thereby reducing the nonlinear distortion of the mid-range speaker and the additional phase shift caused by playback.

[0030] 4. Reducing the width of the front panel can bring more accurate sound and image positioning, making the playback more immersive.

[0031] 5. The low-frequency positive-phase sound waves output by the sound guide tube are low-pass filtered by the sound guide tube cavity, with fewer mid- and high-frequency components, reducing the adverse effects of high-order vibration modes caused by the large amplitude of the woofer, and better achieving isolation between the frequency division and playback bands.

[0032] 6. Since the bass is output through the sound guide tube, the acoustic load of the woofer is appropriately increased, and the low-frequency playback efficiency is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] Although a six-sided box is used in the above embodiments 1-4, the box in the embodiment of the present invention can also adopt other shapes, such as cylindrical, drum-shaped, spherical, spherical, etc. The front baffle and the side baffle are both arranged inside the outer wall of the box. The peripheral edge of the side baffle abuts the inner surface of the outer wall of the box. One side edge of the front baffle abuts the side baffle, and the remaining edge of the front baffle abuts the inner surface of the outer wall of the box, thereby dividing the internal space of the box surrounded by the outer wall of the box into three chambers, namely the mid-high frequency chamber, the bass chamber and the sound guide chamber. The side baffle is shared by the three chambers, one side of the side baffle is the sound guide chamber, and the other side of the side baffle is the mid-high frequency chamber and the bass chamber. The mid-range speaker port and the tweeter port are opened on the outer wall portion of the box corresponding to the mid-high frequency chamber to respectively install the mid-range speaker and the tweeter. A bass sound guide port is provided on the outer wall portion of the box body corresponding to the sound guide cavity, and the bass sound guide port is adjacent to the two aforementioned speaker openings distributed on both sides of the side partition; and a bass port is provided on the portion of the side partition corresponding to the bass cavity to install the bass speaker.

[0073] It should also be noted that the hexahedral enclosures of Examples 1-4 are all right prisms with the upper and lower bases perpendicular to each other. This is the preferred embodiment shape. However, the present invention does not exclude different hexahedral shapes such as oblique prisms, truncated pyramids, and even shapes similar to square pyramids. Those skilled in the art will understand how to implement the specific shape of the speaker enclosure based on the concepts of the present invention.

[0074] In a practical embodiment of the present invention, at least two speaker openings are provided on the front panel, preferably arranged in sequence along the vertical direction.

[0075] In practical implementations of the present invention, a sound guide tube is connected to the front of the woofer. The opening of the sound guide tube is located at the front of the speaker cabinet and is in the form of a flat rectangle, for example, with a short side measuring 0.5cm to 10cm and a long side measuring 5cm to 100cm. Bass is output through the sound guide tube, which appropriately increases the acoustic load on the woofer and significantly improves low-frequency reproduction efficiency. Positioned adjacent to the mid- and high-frequency speakers, the sound image is more precisely positioned.

[0076] In practical embodiments of the present invention, the woofer is mounted on the side baffles in a lateral arrangement, positioned behind the mid-range and tweeter speakers. This allows for the installation of a large-diameter woofer while maintaining a compact size and a narrow frontal dimension. The width of both the left and right side panels can be at least 1.5 times, 2.0 times, or the like, the width of the front panel, thereby creating a narrow front panel (i.e., a narrow front face).

[0077] The speaker of the present invention can also use a frequency divider to make the mid-range speaker operate above the resonant frequency through frequency division, reducing the average phase displacement of the mid-range speaker during playback, thereby reducing the nonlinear distortion of the mid-range speaker and the additional phase shift caused by playback.

[0078] The above description of the embodiments of the novel high-fidelity speaker of the present invention is intended to illustrate the spirit of the present invention. It should be noted that those skilled in the art may modify and combine the features of the aforementioned embodiments without departing from the spirit of the present invention. Therefore, the present invention is not limited to the aforementioned embodiments. Specific features of the novel high-fidelity speaker of the present invention, such as shape, size, and position, can be specifically designed based on the effects of the aforementioned features, and such designs are within the capabilities of those skilled in the art.
