Description

Technical Field

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

[0002] The speaker enclosure is the soul of the entire audio system, and its performance plays a crucial role in the sound quality of the system. Its main characteristic is converting audio electrical energy into sound energy and radiating it into space. Currently, three-way speakers typically refer to enclosures composed of high, mid, and low-frequency drivers. In applications requiring portability, the front panel of the speaker cannot be very large, and can usually only accommodate a limited number of speaker units. Furthermore, in portable or field applications, to prevent damage from impacts, or due to limitations in the speaker's shape and appearance, other sides of the speaker (top, bottom, left, right, and rear) are unsuitable for placing speaker units. This combination makes it difficult to fit multiple speaker units on the front panel during speaker design. Of course, reducing the area of ​​each speaker unit would allow for a larger number of units, but this introduces other problems such as decreased sensitivity, making it undesirable. To address this problem, existing technologies typically employ two methods:

[0003] The first method uses a coaxial speaker unit. A coaxial speaker unit consists of a mid-bass driver and a tweeter, with the tweeter mounted in front of the mid-bass driver. Superficially, this reduces the tweeter's mounting area on the speaker cabinet, but this isn't ideal. Because the tweeter area in a coaxial speaker unit must be designed to be very small, only a small area can be saved; otherwise, it will block the mid-bass driver's sound output. Specifically, midrange signals have poor diffraction capabilities; if the tweeter area is too large, it will obstruct the midrange signal. On the other hand, if the tweeter area is not large enough, its sensitivity and sound pressure level will also be insufficient, thus affecting sound quality. In fact, the original design intention of coaxial speaker units on the market was not to save space, but to allow the sound to originate from the same point—the axis—resulting in more accurate sound image localization.

[0004] The second method involves mounting the mid-bass speaker unit normally on the front panel, with a bracket at the front of the panel supporting the tweeter unit. This is similar to a coaxial speaker unit, but the tweeter unit protrudes from the front of the speaker panel. The midrange signal from the mid-bass unit is more easily emitted around the tweeter, thus having a much smaller impact on sound quality than with a coaxial speaker unit. This front-and-back speaker unit structure is a satisfactory solution for speakers with limited space, such as portable speakers. However, the protruding tweeter unit adds space to the front of the panel, increasing the speaker's size by 10% to 20%. This is wasteful for portable speakers, resulting in excessive size, reduced portability, and a less appealing appearance.

[0005] In recent years, with the trend of intelligentization, more and more products are becoming intelligent, and many intelligent products need to be equipped with speakers to broadcast content. Product design is also trending towards miniaturization and ultra-thinness, which requires that the speakers installed in them also be miniaturized. Ensuring the excellent sound quality of three-way speakers, especially obtaining good high-frequency signals, makes miniaturization and compactness of speakers a challenge. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the present invention provides a speaker with a compact panel, which can not only ensure the excellent sound quality of a three-way speaker, but also has the characteristics of small size, compact structure and easy portability.

[0007] This utility model is achieved using the following technical solution:

[0008] A compact speaker enclosure includes a cabinet, a woofer unit, a midrange speaker unit, a tweeter unit, and a connecting device. The tweeter unit and the woofer unit are assembled into a tweeter-woofer assembly via the connecting device. The tweeter unit is located inside the connecting device and in front of the woofer unit. A bass resonator is provided around the tweeter unit. The midrange speaker unit and the tweeter-woofer assembly are mounted side-by-side on the panel of the cabinet.

[0009] Furthermore, the subwoofer unit is integrally connected to the connecting device.

[0010] Furthermore, the tweeter unit is connected to the connecting device via a bracket.

[0011] Furthermore, the tweeter unit and the woofer unit are coaxially arranged.

[0012] Furthermore, the tweeter unit includes a tweeter A positioned facing the front of the panel; or the tweeter unit includes a tweeter B positioned facing the front left of the panel and a tweeter C positioned facing the front right of the panel; or the tweeter unit includes a tweeter D positioned facing the front left of the panel, a tweeter E positioned facing the front of the panel and a tweeter E positioned facing the front right of the panel.

[0013] Furthermore, a bass chamber is formed inside the enclosure, and the bass chamber has a bass through-hole that communicates with the outside.

[0014] Furthermore, a passive radiator or a phase inverter is configured at the bass vent.

[0015] Furthermore, a midrange cavity is formed inside the enclosure, and the midrange speaker unit is located inside the midrange cavity. The midrange cavity is not connected to the bass cavity.

[0016] Furthermore, the high and low frequency speaker assemblies are provided in multiples, and the multiple high and low frequency speaker assemblies and the mid-range speaker unit are mounted side by side on the panel.

[0017] Furthermore, multiple high and low frequency speaker assemblies and multiple mid-range speaker units are provided, and multiple high and low frequency speaker assemblies and multiple mid-range speaker units are mounted side by side on the panel.

[0018] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0019] This invention connects the tweeter and woofer units into a single tweeter-woofer assembly using a connecting device. The tweeter-woofer assembly and midrange speaker unit are then mounted side-by-side on the cabinet panel. This integrates the woofer, midrange, and tweeter units onto a single panel, providing low, mid, and high-frequency sound output while making the entire panel more compact. Because the tweeter and woofer units are combined on a single connecting device, and the high and low frequencies are emitted from the same direction, a superior blending effect is achieved during transmission, significantly improving the overall sound quality while saving space. This fully utilizes the excellent sound quality of a three-way speaker while effectively reducing the speaker's size, resulting in a more rational and compact structure with better sound performance, meeting the demands for miniaturized and ultra-thin speaker designs.

[0025] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0026] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0027] like Figures 1 to 4 As shown, this utility model provides a compact speaker enclosure, including a cabinet 1, a woofer unit 21, a midrange speaker unit 3, a tweeter unit 22, and a connecting device 23. The tweeter unit 22 and the woofer unit 21 are assembled into a tweeter-woofer assembly 2 via the connecting device 23. The tweeter unit 22 is located inside the connecting device 23 and in front of the woofer unit 21. The tweeter unit 22 is surrounded by a bass resonator 14. The midrange speaker unit 3 and the tweeter-woofer assembly 2 are mounted side by side on the panel 11 of the cabinet 1.

[0028] In this embodiment, the tweeter unit 22 and the woofer unit 21 are connected to form a tweeter-woofer assembly 2 via the connecting device 23. The tweeter-woofer assembly 2 and the midrange speaker unit 3 are then mounted side-by-side on the panel 11 of the enclosure 1. This integrates the woofer unit 21, the midrange speaker unit 3, and the tweeter unit 22 onto a single panel 11, providing low, mid, and high-frequency sound output while making the entire panel 11 more compact. Because the tweeter unit 22 and the woofer unit 21 are combined into a single connecting device 23... Furthermore, a bass outlet 14 is provided around the tweeter unit 22, so that the bass emitted by the rear woofer unit 21 is emitted from the bass outlet 14. In this way, the high and low frequencies can be transmitted from the same direction, and a superior blending effect can be obtained during the transmission process, which greatly improves the overall sound effect. At the same time, it also saves a lot of space. This not only makes full use of the excellent sound quality of the three-way speaker, but also effectively reduces the size of the speaker, making the entire speaker structure more reasonable, more compact and with better sound effect, meeting the needs of speaker miniaturization and ultra-thin design.

[0029] In a preferred embodiment, the subwoofer unit 21 is integrally connected with the connecting device 23.

[0030] In this embodiment, since the bass speaker unit 21 and the connecting device 23 are integrated, the bass speaker unit 21 and the connecting device 23 become a whole structure, which allows the bass speaker unit 21 to be conveniently installed on the panel 11.

[0031] In a preferred embodiment, the tweeter unit 22 is connected to the connecting device 23 via a bracket 24.

[0032] In this embodiment, the woofer unit 21 and the connecting device 23 form an integral structure. The tweeter unit 22 is then connected to the connecting device 23 via a bracket 24, thereby assembling the woofer unit 21, the connecting device 23, and the tweeter unit 22 into a single integral structure. That is, the woofer unit 21 and the tweeter unit 22 are integrated onto the same connecting device 23, compactly forming a high and low frequency sound source structure. The entire panel 11 is more compact and has better sound quality. It is understood that the bracket 24 can be single-arm, double-arm, triple-arm, quadruple-arm, etc., and the connecting device 23 has a hollow cylindrical structure. Connecting the woofer unit 21 and the tweeter unit 22 through this hollow cylindrical structure simplifies the structure, further reducing the space occupied by the speaker and meeting the requirements for speaker miniaturization.

[0033] In a preferred embodiment, the tweeter unit 22 and the woofer unit 21 are coaxially arranged. This allows the bass and treble to propagate synchronously, and since the bass and treble emit sound from the same point, there is less interference between the high and low frequencies, resulting in better sound quality from the speaker.

[0034] In a preferred embodiment, the tweeter unit 22 includes a tweeter A disposed directly in front of the panel 11, so that the tweeter A has a narrower directivity to meet different user needs.

[0035] Of course, in other embodiments, the tweeter unit 22 may also include a tweeter driver B facing the left front of the panel 11 and a tweeter driver C facing the right front of the panel 11. That is, two tweeter drivers are contained inside a woofer unit 21. By setting two tweeter drivers facing different directions, the sound emission angle of the tweeter unit 22 can be widened, so that the tweeter unit 22 has a wider directivity, the high frequency can radiate well in all directions, the sound is evenly diffused in all directions, a relatively perfect sound field distribution can be achieved, and the sound is well reproduced.

[0036] Of course, in another embodiment, the tweeter unit 22 also includes a tweeter driver D facing the left front of the panel 11, a tweeter driver E facing the front of the panel 11, and a tweeter driver E facing the right front of the panel 11. By combining multiple tweeter drivers with different orientations, the sound emission angle of the tweeter unit 22 is further widened, resulting in wider directivity. High frequencies can radiate well in all directions, and sound is evenly diffused in all directions, achieving a relatively perfect sound field distribution and excellent sound reproduction, thus meeting different user needs.

[0037] It is understandable that the number of tweeter units 22 can be designed according to actual needs.

[0038] In a preferred embodiment, a bass chamber 12 is formed inside the enclosure 1, and the bass chamber 12 has a bass through-hole 15 communicating with the outside. The bass through-hole 15 can reduce the air pressure changes inside and outside the bass chamber 12.

[0039] In a preferred embodiment, a passive radiator 4 or a bass reflex port 15 is provided at the bass through-hole 15. By using a passive radiator 4, the bass frequency of the bass speaker unit 21 is significantly extended, improving the bass effect and solving the problem of poor bass performance in small speakers.

[0040] Of course, in other embodiments, a bass reflex port 15 can also be configured to improve the efficiency of the speaker, reduce wind shear noise, and increase bass extension.

[0041] In a preferred embodiment, a midrange cavity 13 is formed inside the enclosure 1, and the midrange speaker unit 3 is located within the midrange cavity 13. The midrange cavity 13 is not connected to the bass cavity 12. By enclosing the midrange speaker unit 3 within the midrange cavity 13, interference between mid- and low-frequency frequencies is avoided. It should be noted that a partition can be provided in the enclosure 1 to separate the midrange cavity 13 from the bass cavity 12, preventing them from communicating.

[0042] As a preferred embodiment, refer to Figure 3 The speaker system comprises multiple high and low frequency speaker assemblies 2, and these multiple high and low frequency speaker assemblies 2 and one midrange speaker unit 3 are mounted side by side on the panel 11. This makes the speaker system adaptable to a wide range of situations, meeting the needs of different applications and greatly facilitating its use.

[0043] Of course, in other embodiments, reference Figure 4 Multiple high and low frequency speaker assemblies 2 and multiple mid-range speaker units 3 are provided, and multiple high and low frequency speaker assemblies 2 and multiple mid-range speaker units 3 are installed side by side on the panel 11 to further meet the speaker usage needs in different occasions.

[0044] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
