Description

Technical Field

[0001] The present application relates to the technical field of electronic devices, and in particular to a speaker and a wearable electronic device. Background Art

[0002] A loudspeaker, commonly known as a "horn", is a transducer device that converts electrical signals into sound signals. When in use, the audio electrical energy causes its vibrating parts (for example, paper cones or diaphragms) to vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound.

[0003] In order to enhance the interactive experience between the electronic device and the user, some electronic devices are often equipped with speakers to implement functions such as voice broadcasting. However, for some electronic devices, such as smart watches, smart bracelets, smart glasses and other wearable electronic devices, the size requirements for the speakers are also high due to their own limited size requirements.

[0004] In particular, as electronic devices gradually develop towards thinness and lightness, the excessive size of the speaker will limit the thinness and lightness of the electronic device. In the prior art, taking a smart watch as an example, the speaker is installed in the middle frame of the smart watch, and the middle frame is provided with a sound guide channel for the speaker to output sound, and the outer peripheral surface of the speaker housing is provided with an annular sealing protrusion (for example, a waterproof silicone protrusion) protruding outward, and the middle frame is provided with an annular sealing rib arranged around the outer periphery of the speaker housing, and the annular sealing protrusion is sealed and connected with the annular sealing rib, so that the speaker housing and the middle frame are sealed and connected, thereby preventing external impurities such as water from entering the interior of the smart watch through the gap between the speaker and the middle frame from the sound guide channel on the middle frame, affecting the performance of its internal electronic components. However, the wall thickness of the annular sealing rib on the middle frame and the gap between the annular sealing rib and the outer peripheral surface of the speaker housing occupy space in the thickness direction of the smart watch, which limits the thinness and lightness of the smart watch.

[0005] Therefore, the speakers in the prior art have the problem of limiting the lightweight design of electronic devices. Summary of the invention

[0006] The embodiments of the present application provide a speaker and a wearable electronic device, which solve the problem that speakers in the prior art limit the lightweight design of electronic devices.

[0007] In a first aspect, an embodiment of the present application provides a speaker, comprising a housing, wherein a sound outlet is provided at one end of the housing in a thickness direction of the housing; and

[0008] The end surface of one end of the shell is also provided with a sealing portion protruding outward along the thickness direction of the shell, and the sealing portion is an annular structure surrounding the outer periphery of the sound outlet.

[0009] By adopting the above technical solution, the speaker provided in the embodiment of the present application is provided with a sealing portion on the end face of one side of the shell, and the sealing portion protrudes from the end face of one side of the shell along the thickness direction of the shell. Through such a design, when the speaker is installed on the wearable electronic device, the sealing portion can be sealed and connected with the inner wall surface of the middle frame, thereby preventing external impurities such as water from entering the interior of the wearable electronic device (i.e., entering the storage space of the wearable electronic device) through the gap between the speaker and the middle frame from the sound guide channel on the middle frame, affecting the performance of its internal electronic components (for example, circuit boards, batteries, etc.). In addition, there is no need to additionally set an annular sealing rib on the inner wall surface of the middle frame and seal it with the sealing portion. This avoids the space occupied in the thickness direction of the wearable electronic device due to the setting of the annular sealing rib, thereby reducing the space occupied by the speaker in the thickness direction of the wearable electronic device in the present application. On the one hand, it is beneficial to the overall lightweight design demand of wearable electronic devices; on the other hand, within the limited thickness space of wearable electronic devices, larger speakers in the thickness direction of the wearable electronic devices can be designed to improve the sound quality of the speakers. Wearable electronic devices using such speakers can take into account both good sound effects and lightweight design requirements.

[0010] In some embodiments, the sealing portion has one end face and another end face arranged opposite to each other in the thickness direction of the shell, one end face of the sealing portion is connected to the end face of one end of the shell, the sealing portion has a tapered structure, and the cross-sectional area of ​​the sealing portion gradually decreases from one end face of the sealing portion to the other end face.

[0011] By adopting the above technical solution, by setting the sealing part as a tapered structure, the deformation ability of the sealing part from one end face to the other end face can be gradually enhanced, especially the deformation ability of the position matching with the middle frame is better. When installed in the middle frame of the wearable electronic device, even if the inner wall surface (i.e., the inner side surface) of the middle frame is uneven due to factors such as processing errors, the deformability of the end of the sealing part can be well combined with the side wall surface of the middle frame, thereby ensuring the sealing between the speaker and the middle frame.

[0012] In some embodiments, the sealing portion is configured as an elastic annular structure.

[0013] By adopting the above technical solution, by setting the sealing part as an elastic ring structure, it is beneficial to further improve the deformability of the sealing part, thereby improving the sealing between the speaker and the middle frame.

[0014] In some embodiments, the sealing portion is integrally formed on an end surface of one end of the housing.

[0015] By adopting the above technical solution, the sealing part is integrally formed with one end of the shell, which can simplify the production process of the speaker on the one hand, and avoid connection leakage points affecting the sealing when the shell and the sealing part are connected on the other hand.

[0016] In some embodiments, the sealing portion is an annular protrusion made of an elastomeric material.

[0017] In some embodiments, no sealing portion is provided on the outer circumferential surface of the housing.

[0018] By adopting the above technical solution, by setting the end face of the shell as a plane extending perpendicularly to the thickness direction and setting the sealing portion on one end face, there is no need to set the sealing portion on the outer peripheral surface of the shell. When the speaker is installed in the middle frame of the electronic device, the end face of the shell of the speaker in the thickness direction can be flush with the inner wall surface of the middle frame, so that the speaker and the middle frame of the electronic device can be connected more compactly in the thickness direction of the speaker.

[0019] In some embodiments, an end surface of one end of the shell is connected to a support frame, and a dustproof net covering the sound outlet is provided on the support frame.

[0020] By adopting the above technical solution, a dustproof net is provided at one end of the shell, so that the dustproof net can protect the sound outlet of the speaker and prevent dust and other impurities from entering the speaker and affecting the performance of the speaker.

[0021] In addition, by providing a support frame connected to the dustproof net, the support frame can not only support the dustproof net, but also support the shell, thereby improving the structural strength of the shell.

[0022] In some embodiments, the support frame extends along the thickness direction inside the dustproof net and is integrally formed with the dustproof net to form a rigid structure.

[0023] By adopting the above technical solution, by setting the supporting frame and the dustproof net as an integrated structure, the dustproof net can be directly formed on the supporting frame without setting an additional dustproof net. On the one hand, it is beneficial to reduce costs. On the other hand, when the supporting frame and the dustproof net are an integrated structure, the structural strength of the shell can be better.

[0024] In some embodiments, when viewed along the thickness direction of the shell, the dustproof mesh covers the entire sound outlet.

[0025] In some embodiments, the housing includes a front housing, the speaker further includes a vibrator, the vibrator is disposed in the front housing and can vibrate relative to the front housing in a thickness direction of the housing, and the sealing portion is disposed on an end surface of one end of the front housing.

[0026] In a second aspect, an embodiment of the present application further provides a wearable electronic device, comprising a middle frame, a sound guide channel being formed on a side wall of the middle frame, and the wearable electronic device further comprises a speaker in the above structure, the speaker being arranged on the inner side of the middle frame, and the thickness direction of the shell of the speaker being parallel to the width direction of the middle frame; wherein

[0027] In the width direction of the middle frame, the inner port of the sound guide channel is aligned with the sound outlet to connect the sound outlet with the outside of the middle frame.

[0028] By adopting the above technical solution, the wearable electronic device provided in the embodiment of the present application is provided with a speaker of the above structure, and since the sealing part of the speaker extends along the width direction of the shell, it does not occupy the space in the thickness direction of the electronic device. This is beneficial to the overall thin and light design requirements of the wearable electronic device on the one hand; on the other hand, within the limited space of the electronic device, a larger speaker can be designed in the thickness direction to improve the sound quality of the speaker.

[0029] In addition, by setting the sound guide channel to extend along the width direction of the middle frame of the shell, it can be avoided that the sound outlet of the wearable electronic device is blocked when the wearable electronic device is worn, thereby affecting the sound effect of the wearable electronic device.

[0030] In some embodiments, the sealing portion is pressed against the inner wall surface of the middle frame opposite to the speaker and surrounds the inner port of the sound guide channel.

[0031] By adopting the above technical solution, the sealing part is pressed against the end face of the middle frame opposite to the speaker, and the sealing part surrounds the inner port of the sound guide channel. In this way, on the basis of achieving sealing between the speaker and the middle frame, the sealing part can avoid blocking the sound guide channel and affecting the sound effect.

[0032] In some embodiments, the wearable electronic device also includes a speaker fixing component, which is fixedly connected to the middle frame and forms a placement space together with the middle frame, and the speaker is fixedly arranged in the placement space.

[0033] By adopting the above technical solution, a speaker fixing component is provided, and the speaker fixing component and the middle frame together form a placement space, and the speaker is fixedly connected to the placement space to achieve the fixation of the speaker.

[0034] In some embodiments, the speaker fixing assembly includes a fixing bracket, the fixing bracket includes a bracket body, and two fixing arms connected to both ends of the bracket body;

[0035] Each fixed arm is detachably connected to the inner side of the middle frame;

[0036] The bracket body extends along the length direction of the wearable electronic device, and its two ends are respectively connected to one end of the two fixed arms to form a placement space between the bracket body and the middle frame.

[0037] By adopting the above technical solution, two fixing arms extending in the width direction are arranged at both ends of the bracket body, and the two fixing arms can wrap the speaker in an enclosing manner, thereby making the speaker more stable.

[0038] In some embodiments, in the width direction of the speaker, the outer contour of the bracket body does not protrude beyond the outer contour of the shell of the speaker.

[0039] By adopting the above technical solution, the outer contour of the bracket body does not protrude beyond the outer contour of the speaker shell, so as to avoid the bracket body occupying the size of the wearable electronic device in the thickness direction and affecting the overall lightweight design of the wearable electronic device.

[0040] In some embodiments, two extension arms corresponding to the two fixed arms are provided on the inner wall of the middle frame at the position corresponding to the speaker, and both extension arms extend toward the inner side of the middle frame along the width direction for positioning the speaker in its length direction.

[0041] By adopting the above technical solution, the loudspeaker is fixed by a frame structure formed by the fixed arm and the extension arm, which is not only conducive to connecting the loudspeaker with other electronic components, but also conducive to heat dissipation of the loudspeaker.

[0042] In some embodiments, the end edge of the speaker shell in the width direction of the speaker is formed into a curved surface structure by an arc transition, and the inner wall surface of each extension arm opposite to the speaker shell is formed with a concave structure adapted to the curved surface structure; and the curved surface structure of the speaker shell is embedded in the concave structure of the extension arm.

[0043] By adopting the above technical solution, the inner wall surface of the extension arm is formed into a concave structure that is compatible with the arc surface structure of the speaker shell. When the speaker fixing assembly is fixed in the placement space, the arc surface structure of the speaker shell is embedded in the concave structure of the extension arm. In this way, not only can the extension arm limit the speaker in the width and length directions, but also in the thickness direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0090] The following specific embodiments illustrate the implementation of the present application, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Although the description of the present application will be introduced in conjunction with some embodiments, this does not mean that the features of this application are limited to the implementation. On the contrary, the purpose of introducing the application in conjunction with the implementation is to cover other options or modifications that may extend based on the claims of the present application. In order to provide a deep understanding of the present application, the following description will include many specific details. The present application can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present application, some specific details will be omitted in the description. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0091] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0092] The following explains the terms that may appear in the embodiments of the present application.

[0093] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0094] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements.

[0095] In recent years, users' demand for wearable electronic devices (for example, smart watches) has been increasing. They not only require wearable electronic devices to have a perfect user experience, but also require wearable electronic devices to have a beautiful appearance and texture, which puts higher and higher requirements on the design of wearable electronic devices. On the one hand, users expect wearable electronic devices to be worn and used in various environments, such as daily hand washing, bathing, swimming, and diving activities, which puts higher requirements on the waterproof performance of wearable electronic devices. On the other hand, wearable electronic devices have strong decorative properties, so users also have high requirements for the appearance of wearable electronic devices, and require wearable electronic devices to be made thinner and lighter. How to make wearable electronic devices thinner and lighter has become a major challenge in structural design.

[0096] A speaker is a transducer element that converts electrical signals into acoustic signals. As a necessary component of wearable electronic devices, the speaker is one of the important functional components of wearable electronic devices and is installed in the middle frame of the wearable electronic devices. In order to ensure the waterproof performance of the wearable electronic devices, a sealing structure needs to be provided between the speaker and the middle frame. However, the sealing structure is arranged around the periphery of the speaker, which occupies a large space in the thickness direction of the wearable electronic device, limiting the lightweight design of the wearable electronic device, that is, it is not conducive to the realization of lightweight design of the wearable electronic device.

[0097] The following illustrates this problem in conjunction with the structure of a wearable electronic device in a solution.

[0098] See also Figure 1a-Figure 2b , Figure 1a Schematic diagram of the three-dimensional structure of wearable electronic devices in some schemes. Figure 1b for Figure 1a Schematic diagram of a partial cross-sectional structure in the width direction of a wearable electronic device. Figure 1c Schematic diagram of the structure of wearable electronic devices without screens in some solutions. Figure 2a Schematic diagram of the three-dimensional structure of a speaker provided for a wearable electronic device in some embodiments. Figure 2b for Figure 2a Schematic diagram of the cross-sectional structure in the thickness direction of the speaker.

[0099] like Figure 1a-Figure 1c As shown, the structure of the wearable electronic device 10' is explained by taking a smart watch as an example. The wearable electronic device 10' includes a middle frame 100', and a screen 110' and a back cover 120' arranged at both ends of the middle frame 100'. The middle frame 100', the screen 110' and the back cover 120' together form an installation space, and a speaker 200' is installed in the installation space.

[0100] In such a wearable electronic device 10 ′, Figure 1b and Figure 2a , Figure 2b As shown, the middle frame 100' is provided with a sound guide channel 101' for the speaker 200' to output sound, or it can be understood that the sound guide channel 101' ( Figure 1b The structure shown by the dotted line in the middle is arranged on the side of the wearable electronic device 10', that is, the sound guide channel 101' of the wearable electronic device 10' extends along the width direction h of the wearable electronic device 10'. The thickness direction g' of the speaker 200' is parallel to the width direction h of the wearable electronic device 10'. At this time, the width direction h' of the speaker 200' is parallel to the thickness direction g of the wearable electronic device 10'.

[0101] Among them, Figure 1b and Figure 2a , Figure 2bAs shown, in order to ensure the waterproof performance of the wearable electronic device 10', a sealing structure is provided between the speaker 200' and the middle frame 100', and the sealing structure includes an annular sealing rib 102' and an annular sealing protrusion 210' (for example, a waterproof silicone protrusion) that are sealed and connected to each other. The annular sealing protrusion 210' is provided on the outer peripheral surface of the housing 300' of the speaker 200' and protrudes outward, and the annular sealing rib 102' is provided on the middle frame 100' (or it can be understood that the annular sealing rib 102' extends from the inner wall surface of the middle frame 100' toward The speaker 200' extends into the installation space and protrudes from the inner wall surface of the middle frame 100', and the annular sealing rib 102' is arranged on the outer periphery of the speaker shell, and is sealed and connected to the annular sealing rib 102' through the annular sealing protrusion 210', so that the shell 300' of the speaker 200' is sealed and connected to the middle frame 100', thereby preventing external impurities such as water from entering the interior of the wearable electronic device 10' through the gap between the speaker 200' and the middle frame 100' from the sound guide channel 101' on the middle frame 100', and affecting the performance of its internal electronic components.

[0102] However, the wall thickness of the annular sealing rib 102' and the gap between the annular sealing rib 210' and the outer peripheral surface of the shell 300' of the speaker 200' occupy the space in the thickness direction g of the wearable electronic device 10', which is not conducive to the lightweight design of the wearable electronic device 10'.

[0103] For example, in some wearable electronic devices 10', the wall thickness of the annular sealing rib 102' is usually set to 0.4mm to 0.7mm. For example, if it is set to 0.6mm, the annular sealing rib 102' will occupy 1.2mm of space in the thickness direction of the wearable electronic device 10'. In other words, such a speaker 200' will limit the thin and light design of the wearable electronic device 10' by at least 1.2mm.

[0104] In summary, the speakers in the prior art have the problem of limiting the lightweight design of electronic devices.

[0105] In response to the above problems, the present application provides a speaker, which is provided with a sealing part on the end face of one end of the shell and protrudes outward along the thickness direction of the shell, and the sealing part is an annular structure surrounding the outer periphery of the sound outlet, so that when the speaker is installed on a wearable electronic device, the sealing part can be sealed and connected with the inner wall surface of the middle frame, and there is no need to additionally provide an annular sealing rib on the inner wall surface of the middle frame and the outer periphery of the speaker shell to be sealed and connected with the sealing part, thereby reducing the space occupied by the speaker in the thickness direction of the electronic device. When a wearable electronic device adopts such a speaker, it can better achieve a lightweight design.

[0106] The speaker provided in the embodiment of the present application can be applied to wearable electronic devices. The wearable electronic devices provided in the present application can be, but are not limited to, smart watches, smart bracelets, smart glasses and other electronic devices that can be worn on the human body. The following is an example of the structure of the wearable electronic device. It should be noted that the following description of the structure of the wearable electronic device is only an example and does not limit the wearable electronic device provided in the present application. In fact, the wearable electronic device may include more or fewer components in the following examples and drawings.

[0107] In order to make the objectives, technical solutions and advantages of the present application clearer, the speaker and wearable electronic device provided in the implementation mode of the present application are described in detail below with reference to the accompanying drawings.

[0108] See also Figure 3a-3c , Figure 3a This is a schematic diagram of the three-dimensional structure of the wearable electronic device according to an embodiment of the present application as viewed from the front. Figure 3b It is a schematic diagram of the three-dimensional structure of the wearable electronic device according to an embodiment of the present application as viewed from the back. Figure 3c It is a schematic diagram of the partial cross-sectional structure of the wearable electronic device in the width direction of an embodiment of the present application.

[0109] like Figure 3a-3c As shown, the wearable electronic device 10 may include a middle frame 200 , a back cover 400 , a screen 500 , a speaker 100 , and a circuit board 600 .

[0110] The back cover 400 is mounted on one side of the middle frame 200, and the screen 500 is mounted on the other side of the middle frame 200. The middle frame 200, the screen 500 and the back cover 400 are surrounded together to form a receiving space 700 (see Figure 3c ). The accommodation space 700 can be used to install internal components such as a battery (not shown in the figure), a circuit board 600, and a speaker 100. The middle frame 200 and the back cover 400 can also protect the wearable electronic device 10 and support the entire device.

[0111] The speaker 100 is disposed inside the middle frame 200. The thickness direction of the housing 120 of the speaker 100 is parallel to the width direction of the middle frame 200. A sound guide channel 210 ( Figure 3c The sound guide channel 210 runs through the side wall of the middle frame 200, one end of which extends to the inner wall surface 201 of the middle frame 200 and is arranged toward the sound outlet 121 of the speaker 100, and the other end of which extends to the outer side surface of the middle frame 200 and is connected to the outside of the wearable electronic device 10, so that the sound generated by the vibration of the speaker 100 can be transmitted to the outside of the wearable electronic device 10 through the sound guide channel 210.

[0112] It should be noted that, in the present application, the thickness direction G1 of the wearable electronic device 10 refers to the direction from the screen 500 to the back cover 400 or from the back cover 400 to the screen 500, and the width direction H1 and the length direction of the wearable electronic device 10 are located in a plane perpendicular to the thickness direction G1, and the width direction H1 and the length direction are perpendicular to each other.

[0113] The thickness direction G2 of the speaker 100 refers to the sound output direction of the speaker, that is, the vibration direction of the vibration element 111 inside the speaker 100 (see Figure 6a Similarly, the width direction H2 and the length direction of the speaker 100 are located in a plane perpendicular to the thickness direction G2, and the width direction H2 and the length direction are perpendicular to each other. The length dimension of the speaker is greater than or equal to its width dimension.

[0114] The width direction of the middle frame 200 is parallel to the width direction H1 of the wearable electronic device 10, the thickness direction G2 of the speaker 100 is parallel to the width direction H1 of the wearable electronic device 10, the width direction H2 of the speaker 100 is parallel to the thickness direction G2 of the wearable electronic device 10, and the length direction of the speaker is parallel to the length direction of the wearable electronic device.

[0115] In one embodiment, if Figure 3c As shown, in the width direction H1 , the inner port of the sound guide channel 210 is aligned with the sound outlet 121 of the speaker 100 to connect the sound outlet 121 with the outside of the middle frame 200 .

[0116] The present application sets the sound guide channel 210 to extend along the width direction of the middle frame 200, so as to avoid the sound guide channel 210 of the wearable electronic device 10 being blocked when the wearable electronic device 10 is worn, thereby affecting the sound output effect of the wearable electronic device 10.

[0117] In order to more clearly understand the speaker provided in the present application and its configuration, the structure of the speaker 100 and the matching method between the speaker and the middle frame 200 are described in detail below.

[0118] See also Figure 4a and Figure 4b , Figure 4a It is a schematic diagram of the three-dimensional structure of the speaker according to the embodiment of the present application. Figure 4b This is a schematic cross-sectional view of the speaker of the embodiment of the present application along its thickness direction. It should be noted that: Figure 4a and Figure 4b It is only a schematic diagram, which is only used to show the setting position of the sealing part 122 on the speaker 100 and the structure of the sealing part 122, and cannot limit the specific structure of the speaker 100.

[0119] like Figure 4a-4bAs shown, the speaker 100 includes a housing 120, and a sound outlet 121 is disposed at one end of the housing 120 in the thickness direction (the direction indicated by G2 in the figure). The end surface of one end of the housing 120 is also provided with a sealing portion 122 protruding outward along the thickness direction of the housing 120 (the direction indicated by G2 in the figure), and the sealing portion 122 is an annular structure surrounding the outer periphery of the sound outlet 121. In other words, as Figure 4a As shown, a sealing portion 122 is disposed on an end surface 123 of one end of the shell 120 . The sealing portion 122 is an annular structure extending around the sound outlet 121 and protrudes outward from the end surface 123 of one end of the shell 120 along the thickness direction G2 of the shell 120 .

[0120] Through such a design, when the speaker 100 is installed on the wearable electronic device 10, Figure 3c As shown, the sealing portion 122 can be sealed and connected to the inner wall surface 201 of the middle frame 200, thereby preventing external impurities such as water from entering the interior of the wearable electronic device 10 (i.e., entering the accommodating space 700 of the wearable electronic device 10) from the sound guide channel 210 on the middle frame 200 through the gap between the speaker 100 and the middle frame 200, affecting the performance of its internal electronic components (e.g., circuit board 600, battery, etc.). In addition, there is no need to additionally set an annular sealing rib arranged around the outer periphery of the speaker housing on the inner wall surface 201 of the middle frame 200 to be sealed and connected to the sealing portion, thereby avoiding the space occupied in the thickness direction of the wearable electronic device due to the provision of the annular sealing rib, and thus reducing the space occupied by the speaker 100 in the thickness direction G1 of the wearable electronic device in the present application. On the one hand, it is beneficial to the overall lightweight design requirement of the wearable electronic device 10; on the other hand, within the limited space of the wearable electronic device 10, a larger speaker 100 in the thickness direction G1 can be designed to improve the sound quality of the speaker 100. The wearable electronic device 10 adopts such a speaker 100 to simultaneously meet the requirements of good sound quality and lightweight design.

[0121] It will be appreciated by those skilled in the art that the shape of the speaker 100 can be freely set.

[0122] In one embodiment, if Figure 4a As shown, the speaker 100 may be approximately rectangular in shape. The speaker 100 has a relatively small size in the thickness direction G2. Figure 3c It is understood that when the speaker 100 is disposed in the wearable electronic device 10 , the thickness direction G2 of the speaker 100 is parallel to the width direction H1 of the wearable electronic device 10 .

[0123] In other alternative embodiments, the view of the speaker 100 in the thickness direction G2 of the speaker 100 may also be circular, track-shaped, square, etc., or it can be understood that the cross-sectional shape of the speaker 100 perpendicular to the thickness direction G2 of the speaker 100 may be circular, track-shaped, square, etc. Specifically, the present application does not limit this.

[0124] It should be understood by those skilled in the art that the sound outlet 121 refers to the sound outlet of the speaker 100, specifically, the sound outlet 121 located at the vibrating member 111 in the thickness direction G2 of the speaker 100 (see Figure 6a ) is an opening directly above the vibrating element 111, and when the vibrating element 111 vibrates and produces sound, the sound can be emitted through the sound outlet 121.

[0125] It should be noted that the housing 120 may encapsulate the entire internal functional components of the speaker, or may encapsulate part of the internal functional components of the speaker, and this application does not impose any limitation on this.

[0126] Furthermore, the shape of the housing 120 is not limited, and may be a cylinder, a cuboid, or the like.

[0127] In one embodiment, if Figure 4a and Figure 4b As shown, the housing 120 may be a rectangular parallelepiped, in which case the length, width and height of the rectangular parallelepiped correspond to the length direction, width direction and thickness direction of the speaker 100 respectively.

[0128] In other alternative embodiments, the housing 120 may be a cylinder, in which case the height of the cylinder corresponds to the thickness direction G2 of the speaker 100. The radial direction of the cylinder may correspond to the length direction and the width direction H2 of the speaker 100.

[0129] It should be noted that the material of the housing 120 is not limited, for example, it can be plastic, silicone, metal and other materials. Among them, by setting the housing 120 to be an elastic material such as plastic, silicone, etc., it can make the speaker 100 and the inner wall surface 201 of the middle frame 200 be combined (see Figure 3c ), the shell 120 can adapt to the shape of the inner wall surface 201 of the middle frame 200, so that the speaker 100 and the inner wall surface 201 of the middle frame 200 are better integrated.

[0130] In one embodiment, if Figure 4a and Figure 4b As shown, the housing 120 may be formed by plastic injection molding.

[0131] It should be noted that the cross-sectional shape of the sealing portion 122 is not limited, for example, it can be a tapered structure, a rectangle, etc. The following further describes in detail the structure of the sealing portion 122 in conjunction with the accompanying drawings. Figure 4b-1 to Figure 4b-7 , Figure 4b-1This is a schematic cross-sectional structure diagram of the first implementation structure of the sealing part of the speaker according to an embodiment of the present application in cooperation with the middle frame. Figure 4b-2 and Figure 4b-3 This is a schematic diagram of the cross-sectional structure of the second implementation structure of the sealing part of the speaker in the embodiment of the present application and its cooperation with the middle frame. Figure 4b-4 and Figure 4b-5 This is a schematic diagram of the cross-sectional structure of the third implementation structure of the sealing part of the speaker in the embodiment of the present application and its cooperation with the middle frame. Figure 4b-6 and Figure 4b-7 The fourth embodiment of the sealing part of the speaker of the present application and the cross-sectional structure diagram of the sealing part and the middle frame are shown in FIG. Figure 4b-1 , Figure 4b-3 , Figure 4b-5 and Figure 4b-7 In FIG. 1 , the dotted line indicates the position of the sealing portion 122 in a natural state, that is, the position when it is not compressed.

[0132] In one embodiment, if Figure 4b , Figure 4b-1 As shown, the sealing portion 122 has an end face and another end face 1221 which are arranged opposite to each other in the thickness direction of the shell 120, and the one end face of the sealing portion 122 is connected to the end face 123 of one end of the shell 120. The one end face of the sealing portion 122 refers to the end face of the sealing portion 122 opposite to the other end face 1221. The sealing portion 122 has a tapered structure, and the cross-sectional area of ​​the sealing portion 122 gradually decreases from the one end face of the sealing portion 122 to the other end face 1221.

[0133] With this structure, the deformation ability of the sealing part 122 from one end surface to the other end surface 1221 can be gradually enhanced, especially the deformation ability of the position matched with the middle frame 200 is good. When installed in the middle frame 200 of the wearable electronic device 10, even if the inner wall surface 201 of the middle frame 200 is uneven due to processing errors and other factors, the easy deformation of the end of the sealing part 122 can be well combined with the inner wall surface 201 of the middle frame 200, thereby ensuring the sealing between the speaker 100 and the middle frame 200.

[0134] In an alternative embodiment, please participate in Figure 4b-2 and Figure 4b-3 As shown, the other end surface 1221 of the sealing portion 122 may also be provided with a fin portion 1221A. When the speaker 100 is installed in the middle frame 200 of the wearable electronic device 10, the fin portion 1221A is used to seal and connect with the inner wall surface 201 of the middle frame 200, which helps to further improve the sealing performance.

[0135] In another alternative embodiment, Figure 4b-4 and Figure 4b-5As shown, the cross section of the sealing portion 122 can also be set to a "T"-shaped structure.

[0136] In this embodiment of the present application, the "T"-shaped structure enables the sealing portion 122 to have better deformation ability, while the area of ​​the other end surface 1221 of the sealing portion 122 is larger. When the speaker 100 is installed in the middle frame 200 of the wearable electronic device 10, the contact and extrusion area between the other end surface 1221 of the sealing portion 122 and the inner wall surface 201 of the middle frame 200 is larger, which is conducive to further improving the sealing between the speaker 100 and the middle frame 200.

[0137] In yet another alternative embodiment, Figure 4b-6 and Figure 4b-7 As shown, the other end surface 1221 of the sealing portion 122 is corrugated. This can make the ductility of the sealing portion 122 better. When the speaker 100 is installed in the middle frame 200 of the wearable electronic device 10, even if the inner wall surface 201 of the middle frame 200 is an inclined surface or a concave-convex structure, the other end surface 1221 of the sealing portion 122 can be deformed with the shape of the inner wall surface 201 of the middle frame 200, and then fit with the inner wall surface 201 of the middle frame 200, which can further improve the sealing between the speaker 100 and the middle frame 200.

[0138] Since the above structure can make the sealing part 122 more deformable and have a larger sealing area, even if the height of the sealing part 122 is designed to be smaller, the sealing between the speaker 100 and the middle frame 200 can be ensured.

[0139] In one embodiment, in combination Figure 4a As shown, the sealing portion 122 is configured as an elastic annular structure, which is conducive to further improving the deformability of the sealing portion 122, thereby improving the sealing between the speaker 100 and the middle frame 200.

[0140] Furthermore, there is no limitation on the connection method between the sealing portion 122 and the housing 120 , for example, it can be bonding, integral molding, etc.

[0141] In one embodiment, if Figure 4a , Figure 4b As shown, the sealing portion 122 is integrally formed on an end surface 123 of one end of the housing 120 .

[0142] This embodiment of the present application can simplify the production process of the speaker 100 by integrally forming the sealing part 122 with one end of the shell 120, and can also avoid connection leakage points that affect the sealing when the shell 120 and the sealing part 122 are connected.

[0143] In other alternative embodiments, the sealing portion 122 and the housing 120 may also adopt a split structure, and the sealing portion 122 is fixedly connected to the end surface 123 of one end of the housing 120 .

[0144] It should be noted that the material of the sealing portion 122 in the present application is not limited, and it can be, for example, a polymer material of an elastomeric material such as silicone, rubber, or silicone rubber.

[0145] like Figure 4a , Figure 4b As shown, in one embodiment, the sealing portion 122 can be configured as an annular protrusion of an elastic material, for example, a silicone annular protrusion, which is integrally formed on an end surface 123 of the housing 120. The end surface 123 of the housing 120 can be understood as the top surface of the housing 120 in the thickness direction of the speaker. In one example, the end surface 123 of the housing 120 is configured as a plane perpendicular to the thickness direction G2 of the speaker 100.

[0146] In other alternative embodiments, the sealing portion 122 may also be configured as a rubber annular protrusion or a silicone rubber annular protrusion.

[0147] In one embodiment, when viewed along the width direction H2 of the speaker 100 , the end surface 123 of the housing 120 in the thickness direction thereof extends parallel to the width direction H2 of the speaker 100 .

[0148] Furthermore, the outer peripheral surface 123A of the shell 120 is not provided with a sealing portion, which can also be understood as the sealing portion of the outer periphery in the prior art is moved and provided on the end surface of the end.

[0149] It should be understood that the outer peripheral surface 123A of the housing 120 refers to a wall surface extending along the thickness direction G2 of the speaker 100, including Figure 6a The upper side wall and the lower side wall are disposed opposite to each other in the width direction H2 of the speaker 100. The outer peripheral surface 123A may also include a front side wall and a rear side wall disposed opposite to each other in the length direction of the speaker 100, and the front side wall and the rear side wall are both connected to the upper side wall and the lower side wall.

[0150] In this embodiment of the present application, by setting the end surface 123 of the housing 120 as a plane extending perpendicularly to the thickness direction G2 of the speaker 100, and setting the sealing portion 122 on one end surface 123, it is not necessary to set the sealing portion 122 on the outer peripheral surface of the housing 120, so that when the speaker 100 is installed in the middle frame 200 of the electronic device, the end surface 123 of the housing 120 of the speaker 100 in the thickness direction G2 of the speaker 100 can be flush with the inner wall surface 201 of the middle frame 200 (see Figure 3c), the speaker 100 and the middle frame 200 of the wearable electronic device 10 can be connected more compactly in the thickness direction G2 of the speaker 100.

[0151] It should be noted that the design size of the sealing portion 122 is not limited. For example, the height of the sealing portion 122 protruding relative to the end surface 123 of one end of the housing 120 ( Figure 4b The dimension m) is in the range of 0.5 mm to 0.7 mm.

[0152] It should be understood that in this embodiment of the present application, the height of the sealing portion 122 protruding relative to the end surface 123 of one end of the housing 120 can be set to any value between 0.5 mm and 0.7 mm. For example, it can be set to 0.5 mm, 0.55 mm, 0.6 mm, 0.7 mm, etc., which should be set according to actual design and use requirements. In other alternative embodiments, the height of the sealing portion 122 protruding relative to the end surface 123 of one end of the housing 120 can be less than 0.5 mm or greater than 0.7 mm, and the present application does not limit this.

[0153] like Figure 3c As shown, when the speaker 100 is installed in the middle frame 200, the sealing portion 122 is pressed against the inner wall surface 201 of the middle frame 200 opposite to the speaker 100, and surrounds the inner port of the sound guide channel 210. In this way, the sealing portion 122 can be prevented from blocking the sound guide channel 210 and affecting the sound effect on the basis of achieving the sealing between the speaker 100 and the middle frame 200.

[0154] Furthermore, a fixing structure for fixing the speaker 100 may be provided in the middle frame 200. Figure 5a and Figure 5b , Figure 5a This is a schematic diagram of the three-dimensional structure of the wearable electronic device without the screen in an embodiment of the present application. Figure 5b for Figure 5a A partial enlarged view of .

[0155] In one embodiment, if Figure 5a As shown, the wearable electronic device 10 also includes a speaker fixing component 300 , which is fixedly connected to the middle frame 200 and forms a placement space 310 together with the middle frame 200 , and the speaker 100 is fixedly arranged in the placement space 310 .

[0156] It should be noted that the structure of the speaker fixing assembly 300 is not limited, and it can be a connecting arm, a connecting block, etc. that fixes the speaker 100 to the middle frame 200.

[0157] In one embodiment, if Figure 5bAs shown, the speaker fixing assembly 300 includes a fixing bracket 320, and the fixing bracket 320 includes a bracket body 321 and two fixing arms 322 connected to both ends of the bracket body 321, each fixing arm 322 is detachably connected to the inner side of the middle frame 200 and extends along the width direction H1 (corresponding to the width direction of the middle frame) of the wearable electronic device 10. The bracket body 321 extends along the length direction of the wearable electronic device 10, and its two ends are respectively connected to one end of the two fixing arms 322, so as to form a placement space 310 between the bracket body 321 and the middle frame 200.

[0158] It should be understood that in other alternative embodiments, each fixed arm 322 may also be along the length direction of the wearable electronic device 10, which should be specifically determined according to the structure of the wearable electronic device 10, and this application does not make the only requirement.

[0159] In this embodiment of the present application, two fixing arms 322 extending along the width direction H1 of the wearable electronic device 10 are provided at both ends of the bracket body 321. The two fixing arms 322 can wrap the speaker 100 in an enclosing manner, thereby making the speaker 100 more stable.

[0160] In one embodiment, if Figure 5b As shown, the middle frame 200 is provided with two extension arms 211 corresponding to the two fixed arms 322 , and the two extension arms 211 both extend toward the inner side of the middle frame 200 along the width direction H1 of the wearable electronic device 10 .

[0161] Those skilled in the art should understand that the arrangement of the fixed arm 322 and the extension arm 211 is not limited.

[0162] In one embodiment, the other end of each fixed arm 322 may be detachably connected to a corresponding extension arm 211 .

[0163] In other alternative embodiments, the other end of one fixed arm 322 may be detachably connected to a corresponding extension arm 211 , and the other end of another fixed arm 322 may be detachably connected to the inner wall surface of the middle frame 200 .

[0164] In other alternative embodiments, the other end of each of the two fixing arms 322 may be detachably connected to the inner wall surface of the middle frame 200 .

[0165] It should be noted that the detachable connection mentioned above can be a snap connection, a screw connection, etc., and this application does not impose any restrictions on this.

[0166] This embodiment of the present application fixes the speaker 100 by means of a frame structure formed by the fixed arm 322 and the extension arm 211 , which is not only beneficial for connecting the speaker 100 with other electronic components, but also beneficial for heat dissipation of the speaker 100 .

[0167] It should be noted that the shapes of the fixed arm 322 and the extension arm 211 are not limited, for example, they can be set to an L-shaped plate structure, a straight plate structure, etc.

[0168] In one embodiment, if Figure 5b As shown, the fixed arm 322 and the extension arm 211 are both configured as L-shaped plate structures.

[0169] It should be noted that the connection method between the fixed arm 322 and the extension arm 211 is not limited, for example, it can be a bolt connection, a snap connection, etc.

[0170] In one embodiment, if Figure 5b As shown, one end of each fixed arm 322 may be disposed in the slot 32 b , and each extension arm 211 is provided with a clamping head 32 a , and the slot 32 b at one end of each fixed arm 322 is clamped and fixed with the clamping head 32 a of the extension arm 211 .

[0171] In one embodiment, if Figure 5b As shown, the extension arm can be configured to form an integral rigid structure with the middle frame 200, one end of each fixed arm 322 is disposed on a clamping head 32a, and a clamping groove 32b is disposed on each extension arm 211. The clamping head 32a at one end of each fixed arm 322 is clamped in the clamping groove 32b of the extension arm 211 to achieve clamping fixation.

[0172] It should be noted that the connection method between the extension arm 211 and the middle frame 200 is not limited, for example, it can be a bolt connection, a snap connection, etc.

[0173] In one embodiment, if Figure 5b As shown, the extension arm 211 is integrally formed on the middle frame 200 .

[0174] In one embodiment, if Figure 5b As shown, in the width direction H2 of the speaker 100, the outer contour of the bracket body 321 does not protrude from the outer contour of the housing 120 of the speaker 100. This can prevent the bracket body 321 from occupying the size of the wearable electronic device 10 in the thickness direction G1, affecting the overall thin and light design of the wearable electronic device 10.

[0175] Those skilled in the art should understand that the outer contour of the bracket body 321 does not protrude from the outer contour of the housing 120 of the speaker 100 means that: in the width direction H2 of the speaker 100, the upper and lower outer contour edges of the bracket body 321 are lower than the outer contour of the housing 120 of the speaker 100; that is, the bracket body 321 does not completely cover the outer peripheral surface 123A of the housing 120 (see Figure 4b That is, the bracket body 321 does not completely cover the two side surfaces of the housing 120 in the width direction H2 (ie, the upper side wall surface and the lower side wall surface mentioned above).

[0176] In one embodiment, if Figure 5b As shown, the end edge arc transition of the shell 120 of the speaker 100 in the thickness direction G2 forms a curved surface structure, and the inner wall surface of each extension arm 211 opposite to the shell 120 of the speaker 100 is formed with a concave structure 211A adapted to the curved surface structure; and when the speaker fixing assembly 300 is fixedly arranged in the placement space 310, the curved surface structure of the shell 120 of the speaker 100 is embedded in the concave structure 211A of the extension arm 211.

[0177] This embodiment of the present application forms an inner wall surface of the extension arm 211 with a concave structure 211A that is compatible with the arc surface structure of the shell 120 of the speaker 100. When the speaker 100 is fixedly set in the placement space 310, the arc surface structure of the shell 120 of the speaker 100 is embedded in the concave structure 211A of the extension arm 211. In this way, the extension arm 211 can not only limit the speaker 100 in the width and length directions, but also limit it in the thickness direction.

[0178] In one achievable manner, Figure 5b As shown, the concave structure 211A is also configured as a curved concave structure.

[0179] In one embodiment, the end surface circumference of the sound guide channel 210 of the middle frame 200 may be provided with an annular recess, and when the speaker 100 is installed in the middle frame 200 of the wearable electronic device 10, the side edge end of the sealing portion 122 may be embedded in the annular recess. With such a structure, a part of the sealing portion 122 may be located in the middle frame 200, which can improve the bonding and sealing between the speaker 100 and the middle frame 200.

[0180] It should be noted that the specific structure and usage type of the speaker 100 are not limited. The working principle and structure of the speaker are described in detail below using an exemplary structure.

[0181] See also Figure 6a , Figure 6a This is a schematic cross-sectional structure diagram of a first embodiment of the speaker of the present application.

[0182] like Figure 6a As shown, the speaker 100 includes, in addition to the housing 120 and the sealing portion 122 mentioned above, a vibrating member 111, a magnetic circuit assembly 112 and a voice coil 113. The voice coil 113 is disposed in the magnetic circuit assembly 112 and can vibrate in the thickness direction G2 of the speaker 100 relative to the housing 120, and the voice coil 113 is connected to the vibrating member 111 and can drive the vibrating member 111 to vibrate in the thickness direction G2 of the speaker.

[0183] In some embodiments, Figure 6a As shown, the magnetic circuit assembly 112 can be composed of an electromagnet or a permanent magnet and form a stable magnetic field, and the voice coil 113 can be set as an electromagnet wound with a coil, and a part of the voice coil 113 is located in the magnetic field formed by the magnetic circuit assembly 112. At this time, when the electrical signal of the sound passes through the coil in the voice coil 113, the voice coil 113 can form a magnetic field that repels or attracts the magnetic circuit assembly 112, so that the voice coil 113 vibrates in the magnetic field formed by the magnetic circuit assembly 112, so that the voice coil 113 drives the vibrator 111 to vibrate and make sound, so as to convert the electrical signal into a sound signal.

[0184] It can be understood by those skilled in the art that the vibration amplitude of the vibration member 111 in the speaker 100 is one of the important parameters that affect the sound performance of the speaker 100. For the same vibration member 111, when the vibration amplitude of the vibration member 111 is larger, the sound pressure level of the vibration member 111 when vibrating and emitting sound is larger, and the loudness of the sound is higher, so that people can hear the sound signal emitted by the speaker 100 more clearly. Especially when the speaker 100 outputs a low-frequency sound signal, since people are less sensitive to low-frequency sound signals, that is, when the speaker 100 outputs a sound signal with the same sound pressure level, people's subjective perception is that the high-frequency sound signal will be louder and clearer than the low-frequency sound signal, or it can be understood that, compared with the medium and high-frequency sound signals, the low-frequency sound signal requires a high sound pressure level so that people can clearly distinguish the low-frequency sound signal in subjective perception. For example, a sound signal with a sound pressure level of 10dB and a frequency of 200Hz is as loud as a sound signal with a sound pressure level of 50dB and a frequency of 40Hz in people's subjective perception.

[0185] In one embodiment, if Figure 6aAs shown, the vibrator 111 can vibrate relative to the magnetic circuit assembly 112 in the thickness direction G2 of the speaker 100 under the drive of the voice coil 113. The magnetic circuit assembly 112 and the vibrator 111 of the speaker 100 are stacked in the thickness direction G2 of the speaker 100. In some embodiments, a portion of the voice coil 113 is located in the magnetic field formed by the magnetic circuit assembly 112, so that the voice coil 113 can vibrate relative to the magnetic circuit assembly 112 in the thickness direction G2 of the speaker 100 under the action of the magnetic field.

[0186] When the speaker 100 does not output sound, the vibrator 111 and the voice coil 113 are both kept at the initial position and in a static state. When the speaker 100 outputs a sound signal, the voice coil 113 of the speaker 100 can vibrate along the thickness direction G2 of the speaker 100 in the magnetic field formed by the magnetic circuit component 112, and the voice coil 113 drives the vibrator 111 to vibrate. The thickness direction and the vibration direction of the vibrator 111 are parallel to the thickness direction G2 of the speaker 100.

[0187] In one embodiment, if Figure 6a As shown, the vibrator 111 is installed in the housing 120, and the voice coil 113 is connected to the vibrator 111. The voice coil 113 is arranged relative to the vibrator 111 in the thickness direction G2 of the speaker 100.

[0188] In a direction perpendicular to the thickness direction G2 of the speaker 100 , the shell 120 is circumferentially arranged on the outside of the voice coil 113 , which can support and protect the vibration member 111 and the magnetic circuit assembly 112 , prevent the voice coil 113 from being squeezed or collided by external forces, and prevent dust, water vapor, etc. from entering the interior of the speaker 100 .

[0189] In one embodiment, if Figure 6a As shown, the vibrating member 111 may include a diaphragm 111A. In addition, the vibrating member 111 may also include a dome 111B. The dome 111B may be understood as a mass block, which may be used to increase the weight of the vibrating member 111, thereby adjusting the frequency of the sound emitted by the vibrating member 111. The outer periphery of the diaphragm 111A is fixedly disposed on the housing 120, and the dome 111B is fixedly disposed on the diaphragm 111A, so that the dome 111B and the diaphragm 111A vibrate. The voice coil 113 is connected to the diaphragm 111A or the dome 111B of the vibrating member 111.

[0190] In one embodiment, if Figure 6aAs shown, the dome 111B and the diaphragm 111A are stacked, there is a gap between the dome 111B and the magnetic circuit assembly 112, and the diaphragm 111A extends outwardly along the circumference of the dome 111B to the housing 120, so that the dome 111B can drive the diaphragm 111A to vibrate relative to the housing 120. And in the direction perpendicular to the thickness direction G2 of the speaker 100, the part of the diaphragm 111A located between the dome 111B and the housing 120 forms a semi-arc folded ear 114 to enhance the stability of the vibration of the dome 111B in the thickness direction G2 of the speaker 100. In other alternative embodiments, the part of the diaphragm 111A located between the dome 111B and the housing 120 can also be set as a wavy folded ear 114. Specifically, the present application is not limited.

[0191] In other alternative embodiments, the area of ​​the diaphragm 111A corresponding to the dome 111B may also be hollow, and it is only necessary to connect the edge of the dome 111B to the shell 120 through the diaphragm 111A and ensure that the dome 111B can vibrate relative to the shell 120.

[0192] In one embodiment, if Figure 6a As shown, the dome 111B is set as a flat plate structure, which can reduce the size of the vibration member 111 in the thickness direction G2 of the speaker 100, thereby minimizing the size of the speaker 100 in the thickness direction G2 of the speaker 100. In other alternative embodiments, the dome 111B can also be set in other structures, such as a hemispherical shape, a conical shape, etc. Specifically, this application does not limit it.

[0193] In one embodiment, if Figure 6a As shown, the dome 111B is made of a rigid material, so that the dome 111B itself is not easily deformed or twisted during the vibration process, and the stability of the vibration is maintained, thereby improving the sound quality of the vibration member 111 and reducing the distortion rate of the sound produced by the speaker 100.

[0194] In one embodiment, if Figure 6aAs shown, the vibrating member 111 and the magnetic circuit assembly 112 are arranged with a relative spacing in the thickness direction G2 of the speaker 100, and the voice coil 113 is connected to the vibrating member 111 at one end facing the vibrating member 111 in the thickness direction G2 of the speaker 100, and the other end of the voice coil 113 is located in the magnetic field formed by the magnetic circuit assembly 112, and can vibrate under the magnetic force of the magnetic circuit assembly 112. It can be understood by those skilled in the art that the specific structure and layout of the voice coil 113 and the magnetic circuit assembly 112 are not limited, for example, the voice coil 113 can be arranged around the outer peripheral side of the magnetic circuit assembly 112, or the magnetic circuit assembly 112 can be arranged around the outer peripheral side of the voice coil 113, or the voice coil 113 can be arranged in the accommodation space of the magnetic circuit assembly 112 (it can be understood that the magnetic circuit assembly 112 includes a central part and a side part, and an accommodation space is formed between the central part and the side part, and the voice coil 113 surrounds the central part of the magnetic circuit assembly 112, and the side part of the magnetic circuit assembly 112 surrounds the voice coil 113).

[0195] In one embodiment, if Figure 6a As shown, the magnetic circuit assembly 112 is formed with a storage space for accommodating the voice coil 113, and the side wall of the storage space is formed by a magnet, thereby forming a stable magnetic field. In addition, a gap is formed between the voice coil 113 and the wall surface of the storage space in a direction perpendicular to the thickness direction G2 of the speaker 100 to prevent the voice coil 113 from colliding with the magnetic circuit assembly 112 during vibration, and at the same time, the distance between the magnetic poles on both sides of the storage space can be reduced, the strength of the magnetic field in the storage space is increased, the force of the magnetic field on the voice coil 113 is increased, and the output efficiency of the speaker 100 is improved.

[0196] In one embodiment, if Figure 6a As shown, the magnetic circuit assembly 112 may include a plurality of permanent magnets 1122, for example, three permanent magnets 1122 may be provided, and the plurality of permanent magnets 1122 are spaced apart in a direction perpendicular to the thickness direction G2 of the speaker 100, and a first magnetic conductive plate 1121 and a second magnetic conductive plate 1123 are provided in the thickness direction G2 of the speaker 100 to clamp the plurality of permanent magnets 1122, and a stable magnetic field is formed in the accommodation space through the magnetic field of the permanent magnets 1122 and the magnetic conductive effect of the first magnetic conductive plate 1121 and the second magnetic conductive plate 1123, so as to ensure that the voice coil 113 can stably vibrate in the accommodation space of the magnetic circuit assembly 112. The second magnetic conductive plate 1123 may constitute the bottom of the speaker 100 in the thickness direction G2 of the speaker 100.

[0197] Those skilled in the art will appreciate that the arrangement and structure of the magnetic circuit assembly 112 are not limited, and it is only necessary to ensure that the magnetic field of the magnetic circuit assembly 112 can drive the voice coil 113 to vibrate and avoid collision between the magnetic circuit assembly 112 and the vibrator 111 .

[0198] The foregoing mainly describes the internal structure and sound-generating principle of the loudspeaker 100 . The structure of the housing 120 of the loudspeaker 100 is described in detail below with reference to the accompanying drawings.

[0199] First, it should be noted that the housing 120 hereinafter refers to the front housing of the speaker 100 , that is, the housing portion of the speaker 100 located outside the dome 111B. Alternatively, it can be understood as the housing portion of the speaker 100 where the sound outlet 121 is disposed.

[0200] This shell 120 is mainly used to encapsulate the circuit board, magnetic circuit assembly 112 and other structures inside the speaker 100 to protect the internal structure of the speaker 100. During processing, it can have a skeleton (see the support skeleton 125 described below), silicone is injected outside the skeleton, and a silicone ring-shaped protrusion is formed on one end of the shell 120 to form a sealing portion 122.

[0201] Further, those skilled in the art should understand that many components are also arranged inside the speaker. In order to prevent dust and other impurities outside the speaker from entering the speaker and causing damage to the speaker and affecting the performance of the speaker, a dustproof structure is also arranged at the sound outlet of the speaker. The dustproof structure adopted by the speaker in some solutions is described below.

[0202] See also Figure 7 , Figure 7 Schematic diagram of the cross-sectional structure of the loudspeaker in some schemes.

[0203] like Figure 7 As shown, the speaker 200' has a sound outlet 220', which is formed on a shell 300', and the shell 300' has a steel sheet frame 310', which avoids the sound outlet 220' of the speaker 200', and a dustproof net 320' is bonded to the top surface of the shell 300' of the speaker 200' (i.e., an end surface of the shell 300' along the thickness direction g' of the speaker 200'), and the dustproof net 320' is bonded to the inner wall surface of the middle frame of the wearable electronic device.

[0204] For this type of speaker 200', since the dustproof net 320' needs to be glued to the sound outlet 220' of the speaker 200' after the speaker 200' is packaged, on the one hand, the process is relatively complicated, which affects the production efficiency; on the other hand, the dustproof net 320' is set on the outside of the speaker 200', and the dustproof net 320' will occupy the space in the thickness direction g' of the speaker 200'. When the thickness space of the speaker 200' is constant, the space in the thickness direction g' occupied by the internal functional components of the speaker 200' will be reduced, thereby affecting the sound quality effect of the speaker 200'.

[0205] Based on the problems existing in the speaker in this solution, the present application proposes a new dustproof structure design solution, which is described in detail below with reference to the accompanying drawings.

[0206] See also Figure 6a In one embodiment, the end surface 123 of one end of the housing 120 (also understood as the top surface of the housing, corresponding to Figure 6a A dustproof net 124 is provided in the end surface of the right side of the middle shell 120.

[0207] like Figure 6a As shown, an end surface 123 of one end of the housing 120 is connected to a support frame 125 , and a dustproof net 124 covering the sound outlet 121 is connected to the support frame 125 .

[0208] It should be noted that the dustproof net 124 and the support frame 125 may be matched in any manner, such as welding, integral molding, etc. The following describes in detail the structural forms that the dustproof net 124 and the support frame 125 may adopt in conjunction with the accompanying drawings.

[0209] In one embodiment, if Figure 6a As shown, the support frame 125 is arranged on the outer peripheral side of the dustproof net 124, and the dustproof net 124 and the support frame 125 are integrally formed, or it can be understood that the dustproof net 124 and the support frame 125 are an integrated structure. The dustproof net 124 covers the sound outlet 121. That is, on a plane perpendicular to the thickness direction G2 of the speaker 100, the dustproof net 124 is located on the inner side of the support frame 125.

[0210] In one embodiment, if Figure 6a As shown, the edge of the dustproof net 124 may be flush with the inner wall surface of the sound outlet 121 .

[0211] In one embodiment, if Figure 6a As shown, the edge of the dustproof net 124 may be extended to the inner wall surface of the sound outlet 121 .

[0212] In one embodiment, if Figure 6a As shown, the support frame 125 extends into the sound outlet 121 , and a plurality of holes are provided in the area where the support frame 125 is located at the sound outlet 121 , thereby forming a dustproof net 124 . The present application does not limit the number of holes.

[0213] This embodiment of the present application provides a dustproof net 124 at one end of the shell 120, so that the dustproof net 124 can protect the sound outlet 121 of the speaker 100 to prevent dust and other impurities from entering the speaker 100 and affecting the performance of the speaker 100.

[0214] Furthermore, by providing a support frame 125 for supporting the dustproof net 124 on the peripheral side of the dustproof net 124 , the support frame 125 can not only support the dustproof net 124 but also support the shell 120 , thereby improving the structural strength of the shell 120 .

[0215] Furthermore, by configuring the support frame 125 and the dustproof net 124 as an integrated structure, the dustproof net 124 can be directly formed on the support frame 125 without configuring an additional dustproof net 124. This is beneficial for reducing costs on the one hand, and on the other hand, when the support frame 125 and the dustproof net 124 are an integrated structure, the structural strength of the shell 120 can be better.

[0216] In one embodiment, if Figure 6a As shown, when viewed along the thickness direction G2 of the speaker 100 , the dustproof net 124 covers the entire sound outlet 121 .

[0217] In one embodiment, the thickness of the housing 120 is within a range of 8.6 mm to 10.9 mm.

[0218] It is understood by those skilled in the art that the thickness of the housing 120 can be set to any size between 8.6 mm and 10.9 mm. For example, 8.6 mm, 9.05 mm, 9.6 mm, 10 mm, 10.9 mm, etc. In other alternative embodiments, the thickness of the housing 120 can also be set to be less than 8.6 mm, or greater than 10.9 mm. The specific setting should be based on actual design or use requirements, and this embodiment does not make the only requirement.

[0219] It will be appreciated by those skilled in the art that the material of the support frame 125 is not limited. Figure 6a As shown, the support frame 125 may be a rigid member, for example, the support frame 125 may be a steel sheet.

[0220] It should be noted that the supporting frame 125, the sealing portion 122 and the housing 120 may be combined in any manner. Figures 6a to 6c Several possible matching methods are described in detail. Figure 6b This is a schematic cross-sectional structure diagram of a second embodiment of the speaker of the present application. Figure 6c This is a schematic cross-sectional structure diagram of a third embodiment of the speaker of the present application.

[0221] In one embodiment, if Figure 6aAs shown, in the thickness direction G2 of the speaker 100, the support frame 125 is disposed in one end of the housing 120 near the sound outlet 121, and the support frame 125 can support the housing 120. In one example, in the thickness direction G2 of the speaker 100, the outer side surface of the support frame 125 (i.e., the side surface away from the sound outlet 121) is aligned with the end surface 123 of one end of the housing 120. In other examples, in the thickness direction G2 of the speaker 100, the outer side surface of the support frame 125 may not be aligned with the end surface 123 of one end of the housing 120.

[0222] In the plane perpendicular to the thickness direction G2 of the speaker 100 , the sealing portion 122 is located between the support frame 125 and the outer peripheral surface 123A of the shell 120 , and the sealing portion 122 is entirely provided on the end surface 123 of one end of the shell 120 .

[0223] See also Figure 6b In another embodiment, a portion of the sealing portion 122 is disposed on an end surface 123 of one end of the shell 120 , and another portion is disposed on an outer side surface of the supporting frame 125 .

[0224] See also Figure 6c In another embodiment, the support skeleton 125 covers the end surface 123 of one end of the shell 120, and the sealing portion 122 is entirely arranged on the outer side surface of the support skeleton 125, or it can be understood that the sealing portion 122 is arranged on the end surface 123 of one end of the shell 120 through the support skeleton 125.

[0225] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
