Abstract
Description
Technical Field
[0001] This application relates to the field of electronic equipment technology, and more particularly to an electronic device. Background Technology
[0002] Electronic devices such as mobile phones and tablets typically place speakers in the mounting slots of the device's casing. The speaker's diaphragm converts electrical signals into sound, which is then transmitted to the outside of the device through sound guide holes in the casing.
[0003] In related technologies, to ensure the dustproof and waterproof performance of electronic devices, a sealing ring with a lip is installed between the speaker and the housing. The outward-curving lip effectively fills the assembly gap between the speaker and the housing. The sealing ring is typically manufactured as a single unit and then glued into the housing. The speaker is placed in the mounting slot, and the sealing ring is pressed to achieve a sealed assembly. During speaker installation, the speaker inevitably scratches the lip of the sealing ring. Because the lip is easily deformed, it can easily flip or curl under the scratching of the speaker. This leads to poor contact between the speaker and the sealing ring, and may even affect the dustproof and waterproof performance of the electronic device. Utility Model Content
[0004] This application discloses an electronic device to solve the problem of poor contact between the speaker and the sealing ring in the related art.
[0005] To solve the above-mentioned technical problems, this application is implemented as follows:
[0006] This application discloses an electronic device, which includes a device housing, a speaker module, and a seal.
[0007] The device housing has a mounting groove, and the side wall of the mounting groove is provided with a sound guide hole. The speaker module is disposed in the mounting groove and has a sound outlet hole, which is arranged opposite to the sound guide hole.
[0008] The sealing element is elastically supported between the speaker module and the sidewall of the mounting groove. The sealing element includes an annular base, a first sealing lip, and a second sealing lip. The annular base has a first surface and a second surface facing away from each other. The annular base surrounds the periphery of the sound guide hole, and the first surface is connected to the sidewall of the mounting groove. The first sealing lip and the second sealing lip are both connected to the second surface, and the first sealing lip is close to the opening of the mounting groove, while the second sealing lip is close to the bottom of the mounting groove.
[0009] The first sealing lip has a first sealing surface for fitting against the edge of the sound outlet, and the second sealing lip has a second sealing surface for fitting against the edge of the sound outlet. Along the direction from the center to the edge of the annular base, the first sealing surface is inclined toward the annular base, and the second sealing surface is inclined away from the annular base.
[0010] The technical solution adopted in this application can achieve the following technical effects:
[0011] The electronic device disclosed in this application improves upon related technologies by providing a seal between the speaker module and the sidewall of the mounting groove. The seal includes an annular base, a first sealing lip, and a second sealing lip. The first surface of the annular base is connected to the sidewall of the mounting groove. Both the first and second sealing lips are connected to the second surface of the annular base, with the first sealing lip near the opening of the mounting groove and the second sealing lip near the bottom of the mounting groove. The first sealing lip has a first sealing surface for engaging with the edge of the sound outlet, and a second sealing surface for engaging with the edge of the sound outlet. Along the direction from the center to the edge of the annular base, the first sealing surface is inclined towards the annular base, and the second sealing surface is inclined away from the annular base. When the speaker module is installed, it is inserted into the mounting slot and initially contacts the lower area of the first sealing surface, preventing the first sealing lip from being flipped over. Guided by the first sealing surface, the speaker module moves further into the mounting slot and contacts the lower area of the second sealing surface, again preventing the second sealing lip from being flipped over. Guided by the second sealing surface, the speaker module moves to the bottom of the mounting slot, pressing the first and second sealing lips firmly against the sidewalls of the slot. This design effectively reduces the probability of flipping or curling, ensuring a reliable seal between the speaker module and the sealing components, thereby improving the dustproof and waterproof performance of the electronic device.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0020] 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.
[0021] The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to the accompanying drawings.
[0022] Please refer to Figures 1 to 5 This application discloses an electronic device, which can be a mobile phone, tablet computer, laptop computer, wearable device, vehicle device, etc. This application does not limit the specific type of electronic device.
[0023] The aforementioned electronic device may include a housing 110, a speaker module 120, and a seal 130. The housing 110 forms the structural basis of the electronic device and has a mounting groove 111 with a bottom. The opening of the mounting groove 111 is opposite to the bottom, and the sidewall of the mounting groove 111 extends from the edge of the bottom towards the opening. The sidewall of the mounting groove 111 is provided with sound guide holes 112, which can be one, two, or more. The speaker module 120 is disposed within the mounting groove 111. During installation, the speaker module 120 needs to be inserted from the opening of the mounting groove 111 and then moved towards the bottom. In other words, the assembly direction of the speaker module 120 is from the opening to the bottom of the mounting groove 111.
[0024] The speaker module 120 has a sound outlet 121, which is positioned opposite to the sound guide hole 112. The sound emitted by the speaker module 120 can be transmitted to the outside of the electronic device through the sound outlet 121 and the sound guide hole 112. In some special usage scenarios, such as wading scenarios, water, dust, and other debris from the outside can easily enter through the sound guide hole 112, and then pass through the assembly gap between the sound outlet 121 and the sound guide hole 112 into the interior of the electronic device, causing damage to the internal components. Based on this, a seal 130 can be provided between the speaker module 120 and the side wall of the mounting groove 111. The seal 130 can be a silicone or rubber component with a certain degree of elasticity. The seal 130 can elastically support the speaker module 120 and the side wall of the mounting groove 111, thereby filling the assembly gap between the sound outlet 121 and the sound guide hole 112. It should be noted that, since the speaker module 120 itself has a high waterproof rating, the sealing element 130 is actually used to fill the assembly gap between the speaker module 120 and the device housing 110, so as to prevent water from entering other areas inside the electronic device. The sealing element 130 actually creates a sound channel between the sound outlet 121 and the sound guide hole 112 to ensure normal sound transmission between the sound outlet 121 and the sound guide hole 112.
[0025] The aforementioned sealing element 130 may include an annular base 131, a first sealing lip 132, and a second sealing lip 133. The annular base 131, the first sealing lip 132, and the second sealing lip 133 may be made of the same material, for example, all of which are made of silicone. The annular base 131 has a first surface and a second surface facing away from each other. The annular base 131 surrounds the periphery of the sound guide hole 112, and the first surface of the annular base 131 is connected to the sidewall of the mounting groove 111. The specific connection method may be bonding, snap-fitting, etc. The first sealing lip 132 and the second sealing lip 133 are both connected to the second surface of the annular base 131. The first sealing lip 132 is close to the opening of the mounting groove 111, and the second sealing lip 133 is close to the bottom of the mounting groove 111. In other words, the first sealing lip 132 and the second sealing lip 133 are arranged sequentially along the assembly direction of the speaker module 120. During assembly, the speaker module 120 will first contact the first sealing lip 132, and during its movement towards the bottom of the mounting groove 111, it will further contact the second sealing lip 133. After the speaker module 120 is installed in place, the speaker module 120 can press the first sealing lip 132, the second sealing lip 133, and the annular base 131 against the sidewall of the mounting groove 111. The elastic deformation of the first sealing lip 132, the second sealing lip 133, and the annular base 131 can fill the assembly gap between the speaker module 120 and the device housing 110.
[0026] The first sealing lip 132 has a first sealing surface 1321 for engaging with the edge of the sound outlet 121, and the second sealing lip 133 has a second sealing surface 1331 for engaging with the edge of the sound outlet 121. Along the direction from the center to the edge of the annular base 131, the first sealing surface 1321 is inclined towards the annular base 131, and the second sealing surface 1331 is inclined away from the annular base 131. In other words, along the direction from the center to the edge of the annular base 131, with the second surface of the annular base 131 as a reference surface, the first sealing surface 1321 gradually decreases, and the second sealing surface 1331 gradually increases. Viewed from the assembly direction of the speaker module 120 (from the opening to the bottom of the mounting groove 111), both the first sealing surface 1321 and the second sealing surface 1331 gradually increase along the assembly direction of the speaker module 120. It should be added that, taking the second surface of the annular base 131 as a reference surface, the first sealing surface 1321 is inclined and forms a first angle with the second surface of the annular base 131, and the second sealing surface 1331 is inclined and forms a second angle with the second surface of the annular base 131. The range of the first angle and the second angle can be 10°-80°, specifically 10°, 15°, 30°, 45°, 60°, 80°, etc.
[0027] In a specific installation scenario, the speaker module 120 enters through the opening of the mounting groove 111 and initially contacts the lower area of the first sealing surface 1321. This ensures a sufficient assembly gap between the speaker module 120 and the first sealing surface 1321, preventing the first sealing lip 132 from being scraped or curled. Guided by the gradually rising first sealing surface 1321, the speaker module 120 moves further towards the bottom of the mounting groove 111 and contacts the lower area of the second sealing surface 1331. Similarly, the assembly gap between the speaker module 120 and the second sealing surface 1331 becomes sufficient, preventing the second sealing lip 133 from being scraped or curled. After the speaker module 120 is installed in place (contacting the bottom of the mounting groove 111), the higher areas of the first sealing surface 1321 and the second sealing surface 1331 effectively fill the assembly gap between the speaker module 120 and the device housing 110, ensuring the dustproof and waterproof performance of the electronic device.
[0028] As described above, the electronic device disclosed in this application improves upon related technologies by providing a seal 130 between the speaker module 120 and the sidewall of the mounting groove 111. The seal 130 includes an annular base 131, a first sealing lip 132, and a second sealing lip 133. The first surface of the annular base 131 is connected to the sidewall of the mounting groove 111, and both the first sealing lip 132 and the second sealing lip 133 are connected to the second surface of the annular base 131. The first sealing lip 132 is close to the opening of the mounting groove 111, and the second sealing lip 133 is close to the bottom of the mounting groove 111. The first sealing lip 132 has a first sealing surface 1321 for fitting with the edge of the sound outlet 121, and a second sealing surface 1331 for fitting with the edge of the sound outlet 121. Along the direction from the center to the edge of the annular base 131, the first sealing surface 1321 is inclined toward the annular base 131, and the second sealing surface 1331 is inclined away from the annular base 131. When the speaker module 120 is installed, it is inserted into the groove of the mounting slot 111 and initially contacts the lower area of the first sealing surface 1321, preventing the first sealing lip 132 from being flipped over. Then, guided by the first sealing surface 1321, the speaker module 120 moves further into the mounting slot 111 and contacts the lower area of the second sealing surface 1331, again preventing the second sealing lip 133 from being flipped over. Guided by the second sealing surface 1331, the speaker module 120 moves to the bottom of the mounting slot 111, pressing the first sealing lip 132 and the second sealing lip 133 tightly against the side wall of the mounting slot 111. This design of the first sealing lip 132 and the second sealing lip 133 effectively reduces the probability of flipping or curling, ensuring reliable sealing contact between the speaker module 120 and the seal 130, thereby improving the dustproof and waterproof performance of the electronic device.
[0029] like Figures 1 to 3 As shown, the first sealing lip 132 is connected to the second surface of the annular base 131. The first sealing lip 132 can extend from the second surface of the annular base 131 toward the center of the annular base 131, and the thickness of the first sealing lip 132 near the center of the annular base 131 is less than the thickness away from the center of the annular base 131. For example, along the extension direction of the first sealing lip 132, the thickness of the first sealing lip 132 can gradually decrease, thereby facilitating the deformation of the first sealing lip 132 when squeezed by the speaker module 120, so as to fully fill the assembly gap between the speaker module 120 and the device housing 110.
[0030] Similarly, the second sealing lip 133 is connected to the second surface of the annular base 131. The second sealing lip 133 can extend from the second surface of the annular base 131 toward the edge of the annular base 131, and the thickness of the second sealing lip 133 near the edge of the annular base 131 is less than the thickness away from the edge of the annular base 131. For example, along the extension direction of the second sealing lip 133, the thickness of the second sealing lip 133 gradually decreases, which facilitates the deformation of the second sealing lip 133 when it is squeezed by the speaker module 120, so as to fully fill the assembly gap between the speaker module 120 and the device housing 110.
[0031] Since there is a height difference between the higher region of the first sealing lip 132 and the lower region of the second sealing lip 133, the speaker module 120 may be obstructed when moving to this location. Therefore, the seal 130 may also include a first transition connection 134 and a second transition connection 135. The first sealing lip 132 has a first end and a second end that are opposite to each other along its own length direction. The second sealing lip 133 has a third end and a fourth end that are opposite to each other along its own length direction. The first end is connected to the third end through the first transition connection 134, and the second end is connected to the fourth end through the second transition connection 135. The first transition connection 134 and the second transition connection 135 may be inclined surface structures, arc surface structures, etc., which can enable a uniform transition between the first sealing lip 132 and the second sealing lip 133, thereby improving the smoothness of the speaker module 120 assembly.
[0032] It should be noted that the first sealing lip 132, the second sealing lip 133, the first transition connection 134 and the second transition connection 135 are connected to each other to form an annular sealing structure surrounding the sound outlet 121.
[0033] like Figure 4 and Figure 5As shown, the structures of the first transition connection 134 and the second transition connection 135 can be the same, and both include a first connection 1341, an arc transition 1342 and a second connection 1343 connected in sequence. The first connection 1341 is connected to the first sealing lip 132, and the second connection 1343 is connected to the second sealing lip 133. The specific connection method can be bonding, hot melt bonding, etc. The arc transition 1342 can make the first sealing lip 132 and the second sealing lip 133 achieve a uniform transition.
[0034] For example, for the first transition connection 134, the first end of the first sealing lip 132 is connected to the first connection 1341, and the third end of the second sealing lip 133 is connected to the second connection 1343; for the second transition connection 135, the second end of the first sealing lip 132 is connected to the first connection 1341, and the fourth end of the second sealing lip 133 is connected to the second connection 1343.
[0035] The aforementioned annular base 131, first sealing lip 132, second sealing lip 133, first transition connection 134, and second transition connection 135 can be manufactured separately and then assembled together by means of bonding, heat fusion, or other methods. In an optional embodiment of this application, the annular base 131, first sealing lip 132, second sealing lip 133, first transition connection 134, and second transition connection 135 can be an integral structure, manufactured by injection molding, which can effectively improve the structural strength and durability of the seal 130.
[0036] To ensure the reliability of the assembly between the speaker module 120, the seal 130, and the device housing 110, the sidewall of the mounting groove 111 may have a first mounting plane 113. The first mounting plane 113 is arranged around the periphery of the sound guide hole 112. The first surface of the annular base 131 may fit with the first mounting plane 113, thereby improving the sealing performance between the seal 130 and the device housing 110.
[0037] Similarly, the speaker module 120 has a second mounting plane 122, which is disposed around the periphery of the sound outlet 121. The first sealing surface 1321 of the first sealing lip 132 and the second sealing surface 1331 of the second sealing lip 133 can respectively fit with the second mounting plane 122, thereby improving the sealing performance between the seal 130 and the speaker module 120.
[0038] In one optional embodiment of this application, the first mounting plane 113 is inclined outward from the mounting groove 111 along the direction from the bottom of the groove to the opening of the groove. The angle between the second mounting plane 122 and the first mounting plane 113 is less than a preset angle, which can be 3°, 5°, 10°, etc. When the angle between the second mounting plane 122 and the first mounting plane 113 is 0°, the second mounting plane 122 and the first mounting plane 113 are parallel to each other. In this case, the assembly reliability between the speaker module 120, the seal 130 and the device housing 110 is better.
[0039] The aforementioned first mounting plane 113 adopts an inclined design, which allows the mounting position of the speaker module 120 to be moved forward, thereby freeing up more space for other components of the electronic device. For example, space can be freed up for the battery mounting area, which is conducive to installing a larger capacity battery to improve the battery life of the electronic device.
[0040] The aforementioned speaker module 120 may include a module housing 123 and a speaker unit 124. The module housing 123 has a receiving cavity, the speaker unit 124 is disposed in the receiving cavity, and the receiving cavity is divided into a first sound cavity 125 and a second sound cavity 126. The first sound cavity 125 is connected to the sound outlet 121, and the second sound cavity 126 is mainly used to enhance the low-frequency effect of the speaker module 120.
[0041] To improve the structural strength of the seal 130, a reinforcing rib 1311 can be provided on the inner peripheral wall of the annular base 131. The material of the reinforcing rib 1311 can be the same as that of the annular base 131. The number of reinforcing ribs 1311 can be one, two or more, etc., which can be flexibly selected according to the size of the seal 130.
[0042] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. For the sake of brevity, they will not be described in detail here.
[0043] 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.
