[0002] This application claims priority to Chinese Patent Application No. 202410500708.7, filed on April 24, 2024, entitled “Audio Device and Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of electronic device technology, specifically relating to an audio device and an electronic device. Background Technology

[0004] A loudspeaker is an electroacoustic transducer that converts electrical energy into sound energy and radiates it through the air to a distance. The core of loudspeaker design lies in completing the design of the front cavity, rear cavity, and components. Among them, the rear cavity mainly provides a space isolated from the front cavity. The larger the volume of the rear cavity, the greater the amplitude of the low-frequency vibration as the diaphragm vibrates back and forth, resulting in a better low-frequency effect for the loudspeaker.

[0005] However, some speakers in related technologies require adhesive for waterproofing and fixing of the speaker unit, which occupies a certain space. This results in a relatively small speaker cavity volume (e.g., less than 0.4cc) when the electronic device is thin (e.g., less than 9mm), which does not meet the factory setting requirements (e.g., 0.4cc) and affects the bass effect. Summary of the Invention

[0006] This application provides an audio device, including: a housing and an audio body disposed within the housing;

[0007] The housing includes a top wall and a bottom wall spaced apart, and a side wall connected between the top wall and the bottom wall;

[0008] The audio body is disposed on the bottom wall and spaced apart from the top wall to form a first cavity. The side wall surrounds the outer periphery of the audio body, and at least a portion of the side wall protrudes outward in a direction away from the audio body to form a second cavity. The first cavity and the second cavity are connected to form a first sound cavity.

[0009] This application also provides an electronic device, including: a device body and the aforementioned audio device;

[0010] The audio device is disposed on the device body, and a second sound cavity is formed between the audio device and the device body;

[0011] The bottom wall is provided with a sound outlet hole, and the device body is provided with a sound outlet channel. Both the sound outlet hole and the sound outlet channel are connected to the second sound cavity.

[0012] In this embodiment, at least a portion of the sidewall protrudes outward in a direction away from the audio body, thereby forming an additional second cavity. This second cavity communicates with the first cavity formed between the audio body and the top wall of the housing, so that the first and second cavities together form a first sound cavity. Based on this, the volume of the first sound cavity can be increased by the additionally formed second cavity without increasing the overall thickness of the audio device, thus meeting factory design requirements. Furthermore, it can improve the bass effect to some extent, alleviating the problem of harshness and shrillness caused by poor bass and increased treble. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of 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, 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.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0026] Referring to Figures 1 to 9, this application discloses an audio device 10, which can be a speaker, or other components. Furthermore, the audio device 10 can be applied to electronic devices, such as mobile phones, tablets, cameras, and smart wearable devices. The disclosed audio device 10 includes a housing 11 and an audio body 12.

[0027] The housing 11 is the basic component of the audio device 10, providing a mounting base for the audio body 12 and the like. For example, the housing 11 can be made of metal, or it can be made of a non-metallic material, and the specific material can be selected according to the actual working conditions.

[0028] Referring to Figures 3, 4, 6 to 8, in some embodiments, the housing 11 includes a top wall 112, a bottom wall 111, and a side wall 113. The top wall 112 and the bottom wall 111 are spaced apart, and the side wall 113 connects the top wall 112 and the bottom wall 111. Thus, the top wall 112, the bottom wall 111, and the side wall 113 together form the inner cavity of the housing 11, providing installation space for components such as the audio body 12.

[0029] It should be noted that the top wall 112 and bottom wall 111 mentioned above represent only two spaced wall structures and do not limit the specific arrangement. In actual working conditions, the top wall 112 can be located at the top, at the bottom, or in other positions. Similarly, the bottom wall 111 can be located at the bottom, at the top, or in other positions.

[0030] For example, the electronic device may include structures such as a display screen 23 and a battery cover 21, as shown in FIG9. The side where the display screen 23 is located can be defined as the front side, and the side where the battery cover 21 is located can be defined as the rear side. When the audio device 10 is applied to the electronic device, the top wall 112 of the housing 11 can be located close to the battery cover 21, and the bottom wall 111 of the housing 11 can be located close to the display screen 23. This arrangement allows the audio device 10 to emit sound from the display screen 23 side of the electronic device.

[0031] In other embodiments, the top wall 112 of the housing 11 may be located close to the display screen 23, and the bottom wall 111 of the housing 11 may be located close to the battery cover 21. This arrangement allows the audio device 10 to emit sound from the battery cover 21 side of the electronic device.

[0032] In addition to the methods described above, the audio device 10 can also emit sound from the side of the electronic device.

[0033] In some embodiments, the housing 11 can be a one-piece molded structure, which can improve the overall strength of the housing 11 and shorten the manufacturing cycle. For example, the housing 11 can be formed by stretching, casting, etc., and the specific method can be selected according to the actual working conditions.

[0034] In other embodiments, the top wall 112, side wall 113, and bottom wall 111 can be connected to form the housing 11, which reduces the manufacturing difficulty of the housing 11. Exemplarily, the top wall 112 and side wall 113 can be fixedly connected by welding, bonding, riveting, or other methods, and the bottom wall 111 and side wall 113 can also be fixedly connected by welding, bonding, riveting, or other methods. Of course, the top wall 112 and side wall 113, and the bottom wall 111 and side wall 113 can also be connected by snap-fit, plug-in, screw-in, or other methods to facilitate assembly and disassembly.

[0035] Optionally, the housing 11 can be a polygonal housing, a circular housing, or an elliptical housing. For example, a polygonal housing may include a triangular housing, a rectangular housing, a square housing, a hexagonal housing, an octagonal housing, etc. It should be noted that the terms polygonal, circular, and elliptical refer to the cross-sectional shape of the housing 11.

[0036] An audio body 12 is disposed within a housing 11 and is used to output audio signals. In some embodiments, the audio body 12 is disposed on a bottom wall 111 and spaced apart from a top wall 112, with side walls 113 surrounding the outer periphery of the audio body 12. Based on this, the bottom wall 111 can support and fix the audio body 12 to ensure its stability. The top wall 112, spaced apart from the audio body 12, forms a first cavity M1. Due to the presence of the first cavity M1, the diaphragm of the audio body 12 can vibrate within the first cavity M1 during sound production, causing the air within the first cavity M1 to vibrate, thereby creating a low-frequency effect. The side walls 113 can surround the audio body 12 for protection.

[0037] For example, the audio body 12 can be fixed to the inner surface of the bottom wall 111, for example, by means of bonding, snap-fitting, screwing, etc., to ensure the stability of the audio body 12 within the housing 11.

[0038] Considering that the larger the volume of the first cavity M1 between the audio body 12 and the top wall 112, the larger the low-frequency amplitude, and the better the low-frequency effect of the audio device 10, the present application embodiment makes structural improvements to the housing 11 of the audio device 10 so that the volume of the first cavity M1 can be increased without increasing the thickness, thereby improving the low-frequency effect.

[0039] In some embodiments, at least a portion of the sidewall 113 protrudes outward toward the direction away from the audio body 12 to form a second cavity M2, and the first cavity M1 and the second cavity M2 are connected to form a first sound cavity M together.

[0040] Based on the above configuration, at least a portion of the sidewall 113 protrudes outward in a direction away from the audio body 12, thereby forming an additional second cavity M2. This second cavity M2 communicates with the first cavity M1 formed between the audio body 12 and the top wall 112 of the housing 11, so that the first sound cavity M is formed together by the first cavity M1 and the second cavity M2. Thus, the first sound cavity M is expanded by the additionally formed second cavity M2 without increasing the thickness of the audio device 10, thereby meeting the factory design requirements and improving the bass effect to a certain extent, so as to alleviate the problem of harshness and sharpness caused by poor bass and increased treble components.

[0041] Referring to Figures 2, 3, 6, and 7, in some embodiments, the sidewall 113 may include a first sidewall portion 1131 and a second sidewall portion 1132 distributed and connected along the direction from the bottom wall 111 to the top wall 112. The end of the first sidewall portion 1131 facing away from the second sidewall portion 1132 is connected to the bottom wall 111, and the end of the second sidewall portion 1132 facing away from the first sidewall portion 1131 is connected to the top wall 112. Thus, the first sidewall portion 1131 surrounds the outer periphery of the audio body 12, and is connected to or spaced apart from the outer peripheral surface of the audio body 12; the second sidewall portion 1132 surrounds the outer periphery of the audio body 12, and at least a portion of the second sidewall portion 1132 protrudes outward in a direction away from the audio body 112 along at least a portion of the circumferential direction of the housing 11, forming a second cavity M2.

[0042] It should be noted that, in the direction from the top wall 112 to the bottom wall 111, the side wall 113 is divided into at least a first side wall portion 1131 and a second side wall portion 1132 in the same direction. The first side wall portion 1131 surrounds the audio body 12, and when the first side wall portion 1131 is connected to the outer peripheral surface of the audio body 12, it can achieve positioning and sealing of the audio body 12, ensuring the positional accuracy, stability, and waterproof and dustproof functions of the audio body 12. Of course, when the first side wall portion 1131 is spaced apart from the outer peripheral surface of the audio body 12, some material can be filled between the first side wall portion 1131 and the outer peripheral surface of the audio body 12. This method can also achieve positioning and sealing of the audio body, ensuring the positional accuracy, stability, and waterproof and dustproof functions of the audio body 12. In addition, the design of the second side wall portion 1132 can further increase the volume of the first sound cavity M without increasing the thickness of the audio device 10, thereby improving the low-frequency performance of the audio device 10.

[0043] In addition, the first sidewall portion 1131 is directly connected to the outer peripheral surface of the audio body 12 or indirectly connected through other materials to position the audio body 12, and also to provide waterproof and dustproof functions; a part of the second sidewall portion 1132 can be connected to the outer peripheral surface of the audio body 12, and the other part can be spaced apart to form the second cavity M2.

[0044] For example, the first sidewall portion 1131 and the second sidewall portion 1132 can be two parts of an integral structure. Of course, the first sidewall portion 1131 and the second sidewall portion 1132 can also be two independent structures, which are then fixedly connected to form the entire sidewall 113.

[0045] In addition, the extending direction of the first sidewall portion 1131 and the extending direction of the second sidewall portion 1132 may be the same or different.

[0046] In some embodiments, there may be an angle between the extending direction of the first sidewall portion 1131 and the extending direction of the second sidewall portion 1132, so as to form a second cavity M2 between the audio body 12 and at least a portion of the outer peripheral region of the second sidewall portion 1132. Exemplarily, the sidewall 113 may be funnel-shaped, that is, the cross-sectional area of ​​the sidewall 113 near the top wall 112 is larger than the cross-sectional area near the bottom wall 111.

[0047] In some embodiments, each region of the second sidewall portion 1132 protrudes outward in the circumferential direction of the housing 11, facing away from the audio body 12. This arrangement creates a second cavity M2 between the second sidewall portion 1132 and the audio body 12. Based on the first cavity M1, the second cavity M2 further expands the volume of the first acoustic cavity M, thereby enhancing the low-frequency performance of the audio device 10.

[0048] In other embodiments, a portion of the second sidewall portion 1132 protrudes outward in the circumferential direction of the housing 11, away from the audio body 12, while another portion of the second sidewall portion 1132 connects to the outer peripheral surface of the audio body 12. Based on this arrangement, a second cavity M2 is partially formed between the second sidewall portion 1132 and the audio body 12. In this case, although the expanded space is reduced, it still achieves the same effect of expanding the first acoustic cavity M compared to the method where the outer peripheral surface of the audio body 12 is completely in contact with the second sidewall portion 1132.

[0049] In addition, in the circumferential direction of the housing 11, the first side wall portion 1131 can completely surround the outer peripheral area of ​​the audio body 12 and achieve full connection, so as to position and seal the outer periphery of the audio body 12.

[0050] In some embodiments, the height of the first sidewall portion 1131 in the direction from the top wall 112 to the bottom wall 111 may be smaller than the height of the audio body 12. Based on this arrangement, at least a portion of the side surface of the audio body 12 can overlap with the second sidewall portion 1132, and since at least a portion of the second sidewall portion 1132 protrudes outward in a direction away from the audio body 12, an additional second cavity M2 can be formed at the overlapping area, which helps to increase the volume of the first acoustic cavity M, thereby improving the low-frequency performance of the audio device 10.

[0051] In other embodiments, the height of the first sidewall portion 1131 in the direction from the top wall 112 to the bottom wall 111 can be greater than the height of the audio body 12. Based on this arrangement, there is no overlapping area between the outer peripheral surface of the audio body 12 and the second sidewall portion 1132. However, since at least a portion of the second sidewall portion 1132 protrudes outward in a direction away from the audio body 12, compared to a configuration where the side of the audio body 12 is completely connected to the second sidewall portion 1132, the outward expansion of the second sidewall portion 1132 can also help increase the volume of the first acoustic cavity M. Furthermore, the above arrangement can also increase the connection area between the first sidewall portion 1131 and the audio body 12, thereby improving the stability and sealing of the audio body 12.

[0052] In some embodiments, the sidewall 113 may further include a third sidewall portion 1133, which is connected between the first sidewall portion 1131 and the second sidewall portion 1132. Thus, the first sidewall portion 1131, the third sidewall portion 1133, and the second sidewall portion 1132 together form the entire sidewall 113, and the third sidewall portion 1133 connects the first sidewall portion 1131 and the second sidewall portion 1132.

[0053] The extension direction of the third sidewall portion 1133 is different from the extension directions of the first sidewall portion 1131 and the second sidewall portion 1132. Therefore, the third sidewall portion 1133 can both connect the first sidewall portion 1131 and the second sidewall portion 1132, and also separate them. Compared to a direct connection between the first sidewall portion 1131 and the second sidewall portion 1132, adding the third sidewall portion 1133 can increase the distance between the second sidewall portion 1132 and the outer peripheral surface of the audio body 12, thereby further increasing the volume of the first acoustic cavity M.

[0054] In some more specific embodiments, the first sidewall portion 1131 and the second sidewall portion 1132 both extend along the direction from the top wall 112 to the bottom wall 111, and the extension direction of the third sidewall portion 1133 is perpendicular to the direction from the top wall 112 to the bottom wall 111. Based on this arrangement, a portion of the sidewall 113 forms a stepped structure. Furthermore, since the first sidewall portion 1131 is sealed to the audio body 12, and the second sidewall portion 1132 is spaced apart from the audio body 12, the third sidewall portion 1133, the second sidewall portion 1132, the top wall 112, the top surface of the audio body 12, and a portion of the side surface of the audio body 12 together form the first acoustic cavity M. Compared to the method where the side surface of the audio body 12 is completely connected to the sidewall 113 of the housing 11, the embodiments of this application can further increase the volume of the first acoustic cavity M, which is beneficial to improving the low-frequency effect of the audio device 10 without increasing the thickness of the audio device 10.

[0055] It should be noted that, considering that at least a portion of the second sidewall portion 1132 protrudes outward in a direction away from the audio body 12, the third sidewall portion 1133 needs to be adapted to the second sidewall portion 1132 when it is provided, so as to avoid connection problems.

[0056] For example, a third sidewall portion 1133 is provided in the area where the second sidewall portion 1132 protrudes outward, while the third sidewall portion 1133 is not provided in the area where the second sidewall portion 1132 does not protrude outward.

[0057] In some embodiments, the housing 11 may be a polygonal housing, in which case the housing 11 may have a plurality of first corners 114 located at the junction of the bottom wall 111 and the first side wall portion 1131. Exemplarily, the housing 11 may be a rectangular housing, in which case the housing 11 may have eight first corners 114.

[0058] Considering that the sidewall 113 of the housing 11 has relatively complex structural features, the shape of the housing 11 becomes more complex. As a result, during the manufacturing process of the housing 11 (e.g., stretching), the first corner 114 of the housing 11 is prone to tearing, which can lead to damage to the housing 11 and failure to meet the usage requirements.

[0059] Based on the above, in this embodiment of the application, a chamfer structure, such as a rounded corner structure, can be added to each first corner 114. The chamfer structure design can effectively alleviate the problem of tearing of the shell 11 at the first corner 114 and ensure the integrity of the shell 11.

[0060] However, considering that the audio body 12 can also be polygonal in shape, it also has multiple second corners 121. For example, the audio body 12 can be a cuboid with eight second corners 121.

[0061] With the audio body 12 placed on the bottom wall 111 of the housing 11, the multiple second corners 121 of the audio body 12 correspond one-to-one with the multiple first corners 114 of the housing 11 located on the bottom wall 111, as shown in Figures 5 and 6. However, as shown in Figure 7, because chamfered structures are added to each of the first corners 114 of the bottom wall 111, the second corners 121 are prone to interference with the corresponding chamfered structures, which causes the audio body 12 to fail to be assembled in place, affecting the positional accuracy and stability of the audio body 12.

[0062] Based on the above, in this embodiment of the application, referring to Figures 1 and 2, each first corner 114 can be expanded outward to form a convex hull structure 115, and each second corner 121 of the audio body 12 is correspondingly disposed within the convex hull structure 115. Thus, through the design of the outwardly expanded convex hull structure 115, a larger accommodating space can be provided for the corresponding second corner 121, preventing the second corner 121 from contacting the housing 11, thereby effectively solving the problem of assembly interference. Furthermore, it also ensures that the first corner 114 of the housing 11 is not easily torn.

[0063] It should be noted that the convex hull structure 115 allows the first corners 114 of the bottom wall 111 to expand outward, forming a larger space, so as to provide a sufficiently large space to accommodate the second corner 121 and prevent interference.

[0064] In other embodiments of this application, the first sidewall portion 1131 and the outer peripheral surface of the audio body 12 may be spaced apart. To achieve sealing and positioning of the audio body 12, the audio device 10 may further include a filling material 13, which is disposed between the outer peripheral surface of the audio body 12 and the first sidewall portion 1131, as shown in FIG8. That is, the first sidewall portion 1131 and the outer peripheral surface of the audio body 12 can be connected by the filling material 13. Based on this arrangement, the audio body 12 can be positioned and fixed by the filling material 13 to ensure the positional accuracy and stability of the audio body 12, and it can also provide a certain degree of sealing, achieving waterproof and dustproof effects.

[0065] It should be noted that in this method, the side wall 113 of the housing 11 is expanded outward without changing its shape, which can also increase the volume of the first sound cavity M, which is beneficial to improving the bass effect of the audio device 10.

[0066] In some embodiments, the height of the filling material 13 in the direction from the top wall 112 to the bottom wall 111 is smaller than the height of the audio body 12. Based on this arrangement, the audio body 12 can be positioned, stabilized, and sealed by the filling material 13, without occupying too much space due to the filling material 13, which is more conducive to increasing the volume of the first acoustic cavity M.

[0067] For example, the filler material 13 can be in the form of plastic, rubber, or plastic.

[0068] In some embodiments, a gap may exist between the first sidewall portion 1131 and the outer peripheral surface of the audio body 12, which facilitates placing the audio body 12 inside the housing 11. For example, the gap may range from 0.05mm to 0.2mm, including, for example, 0.05mm, 0.1mm, 0.15mm, and 0.2mm. Of course, other values ​​are also possible, which are not specifically limited here.

[0069] The existence of the gap will cause the audio body 12 to have a certain amount of wobbling space within the housing 11, resulting in relatively poor stability and positional accuracy of the audio body 12. At the same time, the existence of the gap may also cause external water, dust and other substances to enter the audio device 10, causing the audio device 10 to malfunction.

[0070] Based on the above, this application embodiment seals the gap to improve the stability and positional accuracy of the audio body 12. In addition, it can effectively prevent external water, dust and other substances from entering the audio device 10 and causing damage to the audio device 10.

[0071] The gap can be filled with a sealing material (not shown in the figure). The sealing material can seal the gap to ensure airtightness and achieve waterproof and dustproof effects. In addition, the sealing material can also block the audio body 12 to ensure the positional accuracy and stability of the audio body 12.

[0072] For example, the sealing material can be a sealing strip, a sealing ring, a sealant, etc.

[0073] Based on the aforementioned audio device 10, this application also discloses an electronic device. Referring to Figures 1 to 9, the disclosed electronic device includes a device body 20 and the aforementioned audio device 10. The audio device 10 is disposed on the device body 20, and a second sound cavity N is formed between the audio device 10 and the device body 20. The bottom wall 111 may be provided with a sound outlet 1111, and the device body 20 is provided with a sound outlet channel 24. Both the sound outlet 1111 and the sound outlet channel 24 are connected to the second sound cavity N.

[0074] Based on the above configuration, the audio signal generated by the audio device 10 can enter the second sound cavity N through the sound outlet 1111, and finally be transmitted to the outside through the sound outlet channel 24, so that the electronic device can produce sound.

[0075] Optionally, as shown in FIG9, the device body 20 may include a frame 22, a battery cover 21 and a display screen 23, wherein the battery cover 21 is disposed on one side of the frame 22, the display screen 23 is disposed on the other side of the frame 22, and the audio device 10 is disposed on the frame 22 and located between the battery cover 21 and the display screen 23.

[0076] In some embodiments, the sound outlet 1111 of the audio device 10 may be positioned toward the display screen 23 so as to emit sound from the side closer to the display screen 23.

[0077] In addition, a sound outlet channel 24 can be formed between the frame 22 and the display screen 23. The sound outlet channel 24 is connected to the second sound cavity N so that the audio signal emitted by the audio device 10 can be finally transmitted from the sound outlet channel 24.

[0078] In summary, this application embodiment increases the first acoustic cavity M of the audio device 10 by expanding the side wall 113 of the housing 11 without increasing the overall thickness of the audio device 10. This can help improve the low-frequency performance of the audio device 10, thereby alleviating the problem of harsh and shrill sounds caused by poor bass and increased treble components, and also increasing the manufacturing reliability of the audio device 10.

[0079] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
