Description

Technical Field

[0001] This utility model relates to the field of speaker technology, specifically a speaker that can reduce the area of ​​the sound output panel. Background Technology

[0002] Speakers are widely used in various scenarios, but their structure is often limited by certain applications. For example, due to the constraints of mounting or connecting support devices, common rectangular or near-rectangular speaker structures often cannot accommodate speaker drivers or other functional components on three of the four end faces. This forces the remaining end face to be used for installation, significantly restricting the internal space available for these components.

[0003] Given the limitations on installing functional components within the speaker's internal space, a common design in existing technology is as follows: Figure 1 As shown, its various functional components (such as one or more sound output units including high, mid, and low frequencies) extend axially along the end face where they are allowed to be installed (this end face is the sound output end face), and the functional components are arranged in a straight line. This results in a large area of ​​the sound output end face, which in turn increases the overall volume of the speaker. This not only increases the cost, but also increases the space occupied by the consumer during use. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a speaker that can reduce the area of ​​the sound output panel, which can solve the problems described in the background art.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a speaker that can reduce the area of ​​the sound output panel, including a cabinet, an inner cavity formed inside the cabinet, and a frame installed inside the inner cavity. A sound-generating unit and a diaphragm are installed on the frame, and a sound output channel with an angle is formed on the frame. The sound output channel gradually widens along the direction close to the sound output end face. The sound-generating unit and the diaphragm are both inclined and located on two opposite sides of the sound output channel along the axial direction.

[0006] Furthermore, the included angle is an acute angle.

[0007] Furthermore, the box is rectangular.

[0008] Furthermore, it also includes a first sound output unit, which is mounted on the frame and located on one side of the sound output channel, with the first sound output unit facing the sound output end face.

[0009] Furthermore, the frame includes a connecting part, a first inclined part, a horizontal part, a second inclined part, and a horizontal mounting part connected in sequence, and the area enclosed by the first inclined part, the horizontal part, and the second inclined part constitutes the sound outlet channel.

[0010] Furthermore, a hole is drilled in each of the first inclined part, the second inclined part, and the horizontal mounting part. The hole is a through hole. The sound-generating unit is installed in the hole on the first inclined part, the diaphragm is installed in the hole on the second inclined part, and the first sound-generating unit is installed in the hole on the horizontal mounting part.

[0011] Furthermore, the connecting part and the horizontal mounting part are fixedly connected to the box body, so that the frame body is installed in the inner cavity of the box body.

[0012] Furthermore, the housing is also equipped with several limiting baffles, which are installed in the inner cavity and abut against the frame to limit the position on the frame.

[0013] Furthermore, the limiting baffles are provided on both sides of the inner wall and the bottom wall of the inner box. The connecting part abuts against the limiting baffles on the left inner wall and the bottom wall, and the horizontal mounting part abuts against the limiting baffles on the right inner wall and the bottom wall.

[0014] Furthermore, the transverse portion is arranged parallel to the rear end of the housing at a distance, and the frame divides the inner cavity into two sub-cavities. The two sub-cavities are connected, and the first sound-emitting unit is located in one of the sub-cavities, while the sound-emitting unit is located in the other sub-cavity.

[0015] The beneficial effects of this utility model are: This utility model can effectively reduce the area of ​​the sound output end face, thereby reducing the overall volume of the enclosure, which reduces both the manufacturing cost and the space required during use, and improves the user experience.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 2-7 As shown, a speaker that can reduce the area of ​​the sound output panel includes a cabinet 1, an inner cavity 7 formed inside the cabinet 1, and a frame 5 installed inside the inner cavity 7. A sound-generating unit 6 and a diaphragm 3 are installed on the frame 5, and a sound output channel 4 is formed on the frame 5, with the opening of the sound output channel 4 facing the sound output end face of the cabinet 1.

[0018] It is understandable that the sound-emitting end face is the end face on the enclosure 1 where the sound-emitting panel is located. The sound-emitting panel does not necessarily have to be an independent physical panel installed on the enclosure 1. It can be the end face of the enclosure 1 where the sound is emitted, which is a virtual panel that does not actually exist. Of course, it can also be the end face of the frame 5 facing the sound-emitting end face to form the sound-emitting panel. Therefore, the reduction of the sound-emitting panel area in this embodiment can actually reduce the area of ​​the sound-emitting end face on the enclosure 1 compared with the prior art.

[0019] For example, the enclosure 1 is rectangular. Of course, in actual use, the enclosure 1 is not required to be a standard rectangular structure; it can also be a structure of other shapes that are generally rectangular. Of course, it can also be other non-rectangular structures, but the scenario addressed in this embodiment is as described in the background art. When it is a non-rectangular structure (such as a non-standard rectangular cuboid), the limitations imposed by the application scenario mean that functional components such as the sound output unit can only be installed on the sound output end face.

[0020] The frame 5 forms a sound outlet channel 4 with an angle. The sound outlet channel 4 gradually widens along the direction close to the sound outlet end face, that is, the end away from the sound outlet end face is narrower and the end close to the sound outlet end face is wider. Opposite sound generating units 6 and diaphragms 3 are also installed on the frame 5. The sound generating units 6 and diaphragms 3 are both inclined and located on two opposite sides of the sound outlet channel 4 along the axial direction.

[0021] It is understandable that mounting the sound unit 6 and the diaphragm 3 on the frame 5 at an angle and relative to each other, and placing them in the inner cavity 7 of the enclosure 1, avoids mounting the sound unit 6 and the diaphragm 3 on the sound output end face in a straight line as is the case in the traditional method. This avoids occupying the sound output end face, thereby reducing the area of ​​the sound output end face, which means reducing the area of ​​the sound output panel.

[0022] It is also understandable that forming an angled sound outlet channel 4, narrow at one end and wide at the other, enhances the propulsion of air, thereby making the bass of the sound outlet unit composed of the sound-generating unit 6 and the diaphragm 3 stronger and the low-frequency effect better. From the perspective of sound generation principle, since the angle is similar to a narrow slit, it is equivalent to compressing air and thus increasing kinetic energy, resulting in stronger bass and better low-frequency effect. Furthermore, installing the diaphragm 3 in the inner cavity 7 provides protection compared to the traditional method of directly exposing the diaphragm 3 to the sound outlet surface. In addition, positioning the sound-generating unit 6 and the diaphragm 3 opposite each other on both sides of the sound outlet channel 4 changes the traditional sound output direction of directly emitting sound from the sound outlet surface.

[0023] For example, the included angle is preferably between 5° and 6°.

[0024] For example, it also includes a first sound-emitting unit 2, which is mounted on the frame 5 and located on one side of the sound outlet channel 4. Like the sound-emitting unit 6 and the diaphragm 3, the first sound-emitting unit 2 is located in the inner cavity 7. The first sound-emitting unit 2 faces the sound outlet end face, that is, the sound outlet direction of the first sound-emitting unit 2 is towards the sound outlet end face.

[0025] For example, the frame 5 includes a connecting part 52, a first inclined part 53, a horizontal part 54, a second inclined part 55, and a horizontal mounting part 56 connected in sequence. The area enclosed by the first inclined part 53, the horizontal part 54, and the second inclined part 55 constitutes the sound outlet channel 4. A hole 51 is drilled in each of the first inclined part 53, the second inclined part 55, and the horizontal mounting part 56; the hole 51 is a through hole. The sound-emitting unit 6 is mounted in the hole 51 on the first inclined part 53, the diaphragm 3 is mounted in the hole 51 on the second inclined part 55, and the first sound-emitting unit 2 is mounted in the hole 51 on the horizontal mounting part 56.

[0026] The connecting part 52 and the horizontal mounting part 56 are fixedly connected to the housing 1, so that the frame 5 is installed in the inner cavity 7 of the housing 1.

[0027] For example, the housing 1 is also equipped with several limiting baffles 8, which are installed in the inner cavity 7 and abut against the frame 5 to limit the position of the baffles on the frame 5.

[0028] Limiting baffles 8 are provided on both sides and the bottom wall of the inner box 1. The connecting part 52 abuts against the limiting baffles 8 on the left inner wall and the bottom wall, and the horizontal mounting part 56 abuts against the limiting baffles 8 on the right inner wall and the bottom wall.

[0029] For example, the transverse portion 54 is arranged parallel to the rear end of the enclosure 1 at a distance, where the rear end refers to the end of the enclosure 1 relative to the sound-emitting end face. The frame 5 divides the inner cavity 7 into two sub-cavities. Since the transverse portion 54 does not contact the rear end, the two sub-cavities remain connected. The first sound-emitting unit 2 is located in one of the sub-cavities, and the sound-emitting unit 6 is located in the other sub-cavity.

[0030] This invention can effectively reduce the area of ​​the sound output end face, thereby reducing the overall volume of the enclosure 1, which reduces both manufacturing costs and the space required for use, thus improving the user experience.

[0031] The embodiments disclosed in this specification are merely illustrative of one aspect of the features of this utility model. The protection scope of this utility model is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of this utility model. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
