Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, and more particularly to a loudspeaker structure and electronic product. Background Technology

[0002] The physical model of a speaker is to install a speaker by making a hole in an infinitely large rigid baffle. This ensures that the sound signals from the front and back of the speaker do not form a loop, thus avoiding a situation where only high-frequency sounds with very small wavelengths can propagate out, while other sound signals are superimposed and canceled out.

[0003] In practical use, speaker enclosures cannot be made infinitely large. Therefore, a baffle can be used behind the speaker to create a sealed space to ensure the forward transmission of sound waves. However, this leads to a problem: due to atmospheric pressure, a larger speaker enclosure is more conducive to low-frequency sound reproduction. Therefore, the volume of a speaker enclosure is generally designed based on the size of the mid-bass driver.

[0004] As demands for electronic products increase, these products need to be thin, light, and high-performing, while also making efficient use of space. High-end models often employ a combination of tweeters and woofers, but these speakers take up considerable space and are not easily incorporated into the design of thinner and lighter products.

[0027] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This application provides a speaker structure, including a frame, a magnetic yoke, and a diaphragm. The frame and the magnetic yoke form a groove-like structure, and the diaphragm is then sealed at the opening of the groove-like structure to obtain a sealed chamber. This sealed chamber has the same function as the enclosure of a traditional speaker structure, but it occupies less space.

[0029] The following description, in conjunction with the accompanying drawings, details the various structures of the speaker structure provided in the embodiments of this application, the positional relationships between the structures, and the connection relationships.

[0030] like Figure 1 and Figure 2As shown in the embodiment of this application, the frame 10 and the magnetic yoke 20 are connected and form a groove-shaped structure, and the diaphragm 30 covers the groove opening of the groove-shaped structure. The frame 10, the magnetic yoke 20 and the diaphragm 30 form a sealed chamber 40. The sealed chamber 40 replaces the original speaker box structure. The net volume of the sealed chamber 40 is about 0.3cc, which meets the usage volume requirements of the tweeter.

[0031] Within the sealed chamber 40, a voice coil 70, a magnetic plate 60, and a magnet 50 are sequentially arranged along the direction from the diaphragm 30 to the bottom of the groove structure. The wiring connected to the voice coil 70 passes through the frame 10 or the magnetic yoke 20 to lead out of the sealed chamber 40. A filling structure is provided at the point where the wiring passes through to ensure airtightness. In this embodiment, the type of filling structure is not limited. When the speaker structure is powered on, the voice coil 70 drives the diaphragm 30 to vibrate and produce sound under the current drive. The reverse sound wave from the back of the diaphragm 30 is sealed within the sealed chamber 40, which can achieve the same sound production effect as a conventional speaker.

[0032] The frame 10 or the magnetic yoke 20, or both, are provided with a pressure relief assembly 80 that communicates with the sealed chamber 40. The pressure relief assembly 80 connects the sealed chamber 40 to the outside environment to achieve pressure balance. The specific structure of the pressure relief assembly 80 is described later.

[0033] In this embodiment of the application, the frame 10 and the magnetic yoke 20 are connected and form a groove-shaped structure, wherein the groove-shaped structure can be composed of at least two structural forms.

[0034] Continue to refer to Figure 1 and Figure 2 As shown in the embodiment of this application, the frame 10 is plate-shaped and has through holes, and the magnetic yoke 20 is groove-shaped; the groove of the magnetic yoke 20 is connected to the edge of the through hole, so that the frame 10 and the magnetic yoke 20 form a groove-shaped structure, and the diaphragm 30 is used to cover the through hole.

[0035] like Figure 3 As shown in the embodiment of this application, the frame 10 is cylindrical and the magnetic yoke 20 is plate-shaped; the magnetic yoke 20 blocks one port of the frame 10, so that the frame 10 and the magnetic yoke 20 form a groove-shaped structure, and the diaphragm 30 is used to cover the other port of the frame 10.

[0036] Both structures can form the sealed chamber 40. In both sealed chamber 40 structures, one end of the diaphragm 30 has the same structure, while the structure on the opposite side of the diaphragm 30 differs slightly. For example, when the magnetic yoke 20 is grooved, the opposite side of the diaphragm 30 includes the bottom structure of the grooved structure, and the top edge of the grooved structure is the frame 10; when the frame 10 is cylindrical, the opposite side of the diaphragm 30 has a planar structure. Both methods achieve the same sound production effect, and the slight differences in structure allow for adaptation to different speaker installation scenarios.

[0037] For example, in this embodiment, the frame 10, the magnetic yoke 20 and the diaphragm 30 are connected and the outline shape is a cuboid, so that the speaker structure is set to a regular shape, making it a standard part, which is convenient for installation and operation.

[0038] For example, the bottom of the magnetic yoke 20 includes a planar mounting end face; the horn structure is attached to the connected structure through the mounting end face. The bottom of the magnetic yoke 20 is located on the opposite side of the diaphragm 30, which is the mounting side of the horn structure. Setting it as a planar structure facilitates the installation of the horn structure and reduces the space occupied by the horn structure.

[0039] For example, at least one set of opposite sides of the frame 10 are provided with mounting components 11 for fixing the speaker structure. The mounting components 11 may include ear plates with mounting holes for fixing to the structure to which the speaker structure is connected.

[0040] In this embodiment, the connection between the magnetic yoke 20 and the frame 10 is sealed by a sealing structure; the sealed chamber 40 is a sealed structure and is connected to the outside of the sealed chamber 40 through the pressure relief component 80.

[0041] The magnetic yoke 20 and the frame 10 are separate structures. When the sealed chamber 40 is formed, a sealed connection is required. Therefore, a sealing structure is set at the connection between the magnetic yoke 20 and the frame 10 to maintain the sealing of the connection between the components.

[0042] For example, the sealing structure includes sealant; the connection between the magnetic yoke 20 and the frame 10 is sealed by sealant.

[0043] like Figure 4 As shown in the embodiment of this application, the pressure relief assembly 80 includes a groove 81, a pressure relief hole 82, and a baffle 83; the groove 81 is disposed on the frame 10 and / or the magnetic yoke 20, the pressure relief hole 82 is located in the middle of the bottom plate of the groove 81 and communicates with the sealing chamber 40; the baffle 83 is located in the groove 81 and is fixedly connected to the groove 81. For example, a connecting rib is provided at the edge of the baffle 83, and the connection between the baffle 83 and the groove 81 is realized by the connecting rib.

[0044] The baffle 83 is spaced apart from the bottom plate of the groove 81 on the side facing it, and there is a gap between the edge of the baffle 83 and the inner wall of the groove 81. The air in the sealed chamber 40 is connected to the outside through the pressure relief hole 82.

[0045] For example, the surface of the baffle 83 is flush with the surface of the frame 10 or the magnetic yoke 20, thus forming an integral structure and avoiding the formation of obvious protrusions or depressions at the location of the pressure relief assembly 80.

[0046] In this embodiment, the length of the frame 10, the magnetic yoke 20, and the diaphragm 30 after connection ranges from 14 mm to 18 mm, the width ranges from 8 mm to 12 mm, and the height ranges from 2 mm to 3 mm.

[0047] For example, the speaker structure has a length of 16 mm, a width ranging from 10 mm, and a height ranging from 2.85 mm. By redesigning the speaker structure, its size can be effectively reduced, and its overall weight is also reduced by more than 2 grams compared to traditional speakers. Furthermore, performance testing of the new speaker structure shows that, despite its smaller size, it achieves a higher sound pressure level in high-frequency characteristics compared to traditional speakers.

[0048] This application provides an electronic product including the aforementioned speaker structure. This speaker structure utilizes a groove-like structure formed by a frame 10 and a magnetic yoke 20 to replace the traditional speaker enclosure structure, ensuring product performance while reducing the volume occupied by the speaker structure, thus facilitating the miniaturization of electronic products.

[0049] This application provides a speaker structure and electronic product. A frame 10 and a magnetic yoke 20 form a slotted structure required for the speaker. A magnet 50, a magnetic plate 60, and a voice coil 70 are placed within the slotted structure, and the slot opening is sealed by a diaphragm 30. The sealed cavity 40 formed by the frame 10, the magnetic yoke 20, and the diaphragm 30 replaces the enclosure in a traditional speaker structure. When the speaker is powered on, the voice coil 70, driven by the current, pushes the diaphragm 30 to vibrate and produce sound. The reverse sound wave from the back of the diaphragm 30 is sealed within the sealed cavity 40, achieving the same sound production effect as a traditional speaker structure. The technical solution of this application features a simple, low-cost, and smaller speaker structure, effectively reducing the space required for the speaker structure. Its regular shape also facilitates manufacturing and assembly.
