Description

Technical Field

[0001] This application relates to the field of waterproof mobile phone speaker technology, and more particularly to a waterproof speaker structure for a rugged mobile phone. Background Technology

[0002] With the rapid development of mobile communication technology, rugged phones (waterproof, dustproof, and drop-proof) are increasingly used in outdoor work, special industries, and extreme sports, highlighting the growing conflict between their acoustic and waterproof performance. Traditional rugged phones, to meet waterproofing requirements, typically place the speaker at the rear or employ a multi-layered sealed structure, resulting in a prolonged sound wave transmission path, significant high-frequency energy loss, and a marked decrease in volume and clarity. Furthermore, the sound pressure buildup inside the sealed cavity further suppresses the speaker diaphragm's vibration amplitude, causing low-frequency distortion. While existing solutions, such as waterproof and breathable membranes, can balance air pressure, improper cavity structure and sound guidance path design can still lead to sound wave reflection interference or mid-frequency attenuation. Utility Model Content

[0003] This application provides a waterproof speaker structure for a rugged mobile phone, which achieves front-facing sound output while optimizing and shortening the sound conduction path, thus ensuring its waterproof performance and reducing space occupation.

[0007] A waterproof and breathable membrane covers the sound guide hole.

[0008] As a preferred embodiment, the speaker bracket includes a bracket body, a first clamping member, and a second clamping member; the bracket body is disposed on the front shell assembly; the first clamping member and the second clamping member are disposed on the bracket body, and the first clamping member and the second clamping member surround to form the mounting groove, the mounting groove being located on the side of the bracket body opposite to the front shell assembly; the bracket body has the speaker hole, the speaker hole penetrating the bracket body and being concentrically arranged with the mounting groove, forming a first cavity with the speaker body.

[0009] As a preferred embodiment, the speaker body is positioned in the mounting groove via a silicone gasket.

[0010] As a preferred embodiment, the front housing assembly has a first protrusion on the side facing the speaker bracket, and the first protrusion surrounds the sound guide hole.

[0011] As a preferred embodiment, the end of the first protrusion facing away from the front housing assembly is provided with an elastic sealing layer.

[0016] As a preferred embodiment, the system also includes a rear shell assembly that engages with the front shell assembly to form a receiving cavity, and the horn assembly is located within the receiving cavity.

[0017] The beneficial effects of this application are:

[0018] The waterproof speaker structure of this rugged phone includes a speaker assembly, a front shell assembly, and waterproof adhesive. The speaker assembly includes a speaker body and a speaker bracket. The speaker bracket has a mounting groove, and the speaker body is disposed in the mounting groove. The speaker bracket has a speaker hole and forms a first cavity with the speaker body. The front shell assembly has a sound guide hole corresponding to the speaker hole, and the sound guide hole is connected to the first cavity to form a second cavity. The waterproof adhesive covers the sound guide hole.

[0019] The dual structure, consisting of a first cavity formed by the speaker bracket and the speaker body, and a second cavity that connects to the sound guide hole, creates a continuous acoustic channel. This reduces sound reflection loss, improves low-frequency response and clarity, and ensures that the sound propagates directly from the front, avoiding distortion or volume attenuation caused by obstruction.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0029] likeFigures 1 to 4 As shown, this application provides a waterproof speaker structure for a rugged mobile phone, including a speaker assembly 4, a front shell assembly 3, and a waterproof adhesive backing 5; the speaker assembly 4 includes a speaker body 42 and a speaker bracket 41, the speaker bracket 41 is provided with a mounting groove 415, and the speaker body 42 is disposed in the mounting groove 415; the speaker bracket 41 is provided with a speaker hole 411, and forms a first cavity with the speaker body 42; the front shell assembly 3 is provided with the speaker assembly 4; the front shell assembly 3 is also provided with a sound guide hole 32 corresponding to the speaker hole 411, and the sound guide hole 32 is connected to the first cavity to form a second cavity; the waterproof adhesive backing 5 covers the sound guide hole 32.

[0030] The speaker body 42 is embedded in the mounting groove 415 of the speaker bracket 41, forming a stable fixed structure. The speaker hole 411 on the speaker bracket 41 and the speaker body 42 together form a first cavity, serving as the initial transmission space for sound waves and preventing direct sound leakage or interference from the external environment. The sound guide hole 32 of the front shell assembly 3 is aligned with the speaker hole 411, i.e., the sound guide hole 32 and the speaker hole 411 are axially aligned, forming a second cavity to ensure that the sound waves are transmitted in a straight line. This forms a front-mounted speaker, ensuring that the speaker sound is transmitted from the speaker body 42 through the first cavity and the second cavity through the sound guide hole 32, allowing the sound waves to be transmitted without loss through the continuous cavity channel, thereby achieving front-mounted sound output with a large volume without affecting the speaker sound output effect. In other words, the front shell assembly 3 directly connects the sound guide hole 32 and the speaker hole 411 to form a second cavity. The second cavity is formed, shortening the path length and ensuring that the sound propagates directly from the front, reducing the diffraction loss of high-frequency sound waves during transmission. The waterproof adhesive 5 covers the sound guide hole 32. Preferably, the waterproof adhesive 5 can be located on the side of the front shell assembly 3 away from the speaker bracket 41, that is, on the outside of the sound guide hole 32; it can also be set inside the sound guide hole 32 to physically block water, dust and other substances from entering the second cavity through the sound guide hole 32. When the speaker diaphragm vibrates, the waterproof adhesive 5 quickly balances the air pressure inside and outside the cavity through the breathable micropores, eliminating the suppression of diaphragm amplitude caused by sound pressure accumulation in traditional sealing structures, and significantly improving low-frequency response. In addition, under the seal of the waterproof adhesive 5, even if external liquid seeps into the sound guide hole 32, it will be intercepted by the sealing layer, and under the isolation of the dual cavity channel, it cannot enter the first cavity and the speaker body 42. In other words, by using the dual-cavity channel for front-facing sound output and external sealing for dual protection, the front-facing sound output is optimized and the sound path is shortened, while ensuring its waterproof performance and reducing the space occupied, thus achieving a balance between waterproofing and sound quality in a compact space.

[0031] In this embodiment, as Figure 2As shown, the speaker bracket 41 includes a bracket body 416, a first clamping member 413, and a second clamping member 414; the bracket body 416 is disposed on the front shell assembly 3; the first clamping member 413 and the second clamping member 414 are disposed on the bracket body 416, and the first clamping member 413 and the second clamping member 414 surround to form the mounting groove 415, the mounting groove 415 being located on the side of the bracket body 416 away from the front shell assembly 3; the bracket body 416 is provided with the speaker hole 411, the speaker hole 411 penetrating the bracket body 416 and being concentrically arranged with the mounting groove 415, and forming a first cavity with the speaker body 42.

[0032] Specifically, the first clamping member 413 and the second clamping member 414 clamp the speaker body 42 and fix it in the mounting groove 415, making the assembly structure of the speaker body 42 and the speaker bracket 41 more stable. The structural limitation of the first clamping member 413 and the second clamping member 414 ensures that its vibration direction is perpendicular to the sound wave transmission path, reducing low-frequency resonance distortion caused by installation gaps, and further preventing displacement and detachment when dropped. The speaker hole 411 is in communication with the mounting groove 415 and forms a first cavity with the speaker body 42. Preferably, the bracket body 416 has a second protrusion 412, and the second protrusion 412 surrounds the speaker hole 411 and is provided on the side facing the front shell assembly 3. Preferably, the second protrusion 412 is integrally formed with the bracket body 416. The second protrusion 412 and the speaker body 42 form a first cavity so that the speaker sound is transmitted out through the first cavity without affecting the transmission of the speaker sound. Furthermore, the first protrusion 33 and the second protrusion 412 are correspondingly arranged, and the width of the second protrusion 412 is not less than the width of the first protrusion 33. That is, the second protrusion 412 can cooperate more stably with the first protrusion 33, further enhancing the bonding strength between the first cavity and the first protrusion 33, forming a more stable second cavity, so that the sound from the speaker can be transmitted to the second cavity and transmitted out, while ensuring that the sound propagation is not adversely affected, thereby maintaining the clarity and propagation effect of the speaker sound.

[0033] In this embodiment, as Figure 3As shown, the speaker body 42 is mounted in the mounting groove 415 via a silicone gasket 6. The speaker body 42 is sealed and mounted within the mounting groove 415 of the speaker bracket 41 by the silicone gasket 6, achieving a waterproof seal for the speaker body 42 and further preventing moisture from entering through gaps, thus forming multiple layers of protection. Preferably, the silicone gasket 6 can also be liquid silicone or waterproof white glue; the specific process of its sealing and waterproofing treatment is as follows: after the speaker bracket 41 and the speaker body 42 are bonded together with adhesive, liquid silicone is used for sealing, so that the speaker body 42 is sealed in the mounting groove 415 to form a waterproof first cavity; then, by fixing with clips, adhesives or screws, the sealing connection between the speaker body 42 and the speaker bracket 41 can be made more stable, preventing it from falling off, thereby achieving the IP68 waterproof effect; it should be noted that the structure of the speaker bracket 41 determines the direction and size of the sound output of the speaker body 42, so it can also be determined that the sound output direction of the speaker body 42 is the front direction, and the cross-sectional shape of the speaker body 42 facing the front shell assembly 3 is irregularly wavy, which makes its sound output effect better.

[0034] In this embodiment, as Figure 3 and Figure 4 As shown, the front shell assembly 3 has a first protrusion 33 on the side facing the speaker bracket 41, and the first protrusion 33 surrounds the sound guide hole 32; preferably, the first protrusion 33 is integrally formed with the front shell assembly 3.

[0035] The first protrusion 33 serves as an extension of the sound guide hole 32, guiding sound waves from the first cavity to be concentrated and transmitted through the sound guide hole 32, reducing sound energy scattering and improving volume and clarity. Furthermore, the edge of the waterproof adhesive 5 and the edge of the sound guide hole 32 retain a gap, forming a sound wave diffraction notch, guiding some high-frequency sound waves to exit at a non-perpendicular angle, avoiding standing wave interference caused by perpendicular reflection. It is important to note that there is a certain distance between the first protrusion 33 and the speaker bracket 41, meaning the first protrusion 33 does not directly contact the second protrusion 412, avoiding vibration transmission or sound wave reflection interference caused by rigid connection, and reducing sound distortion. This distance also reduces the direct contact of condensate caused by internal and external temperature differences with the speaker body 42, lowering the risk of short circuits. Preferably, the space between the first protrusion 33 and the second protrusion 412 can be filled with a soft sealing material, such as expanding foam, to further absorb any infiltrated trace amounts of moisture. This makes the first protrusion 33 act as a second line of waterproofing, increasing the difficulty of moisture intrusion. Even if external liquid breaks through the waterproof backing 5, i.e., the waterproof membrane outside the sound guide hole 32, it still needs to bypass the tortuous channel between the first protrusion 33 and the second protrusion 412 to enter the speaker. In addition, the first protrusion 33 is made of sound-absorbing material, which can further suppress high-frequency noise and improve sound quality.

[0036] In other words, the structure of the first protrusion 33 and the second protrusion 412 achieves the extension of the liquid penetration path in a compact space through the dual effects of physical isolation and acoustic guidance, forming a synergistic protection with the waterproof adhesive 5, while optimizing the direction of sound wave transmission and reducing vibration interference.

[0037] In this embodiment, an elastic sealing layer is provided at the end of the first protrusion 33 facing away from the front shell assembly 3. The elastic sealing layer is located between the first protrusion 33 and the second protrusion 412, so that the first protrusion 33 and the second protrusion 412 form an interference fit. Preferably, the elastic sealing layer can be a UV fixing adhesive, silicone, or foamed rubber. Specifically, the elastic sealing layer is fixed at the end of the first protrusion 33, covering the contact surface of the first protrusion 33 and the second protrusion 412. Preferably, the corresponding positions of the first protrusion 33 and the second protrusion 412 are grooves or planes. Therefore, when the elastic sealing layer is compressed, it fills the micro gaps and forms a tight seal, so that the first cavity and the second cavity form a more complete acoustic chamber and reduce sound distortion. At the same time, due to the interference fit of the elastic sealing layer forming an active compression seal, even if it is subjected to water pressure impact and immersed in water, it can maintain the sealing performance through elastic deformation and avoid water leakage caused by instantaneous gaps. In addition, the interference fit eliminates the air gap between the first cavity and the sound guide hole 32, reduces the energy loss of sound waves during transmission, and increases the external volume.

[0038] In this embodiment, the compression amount of the elastic sealing layer is 0.5mm to 1.5mm to ensure that the sealing layer can effectively fill the gap under pressure while avoiding excessive compression that could lead to material fatigue or sealing failure. The compression amount is the difference between the free-state thickness of the elastic sealing layer and its assembled thickness. Preferably, the elastic sealing layer is an adjustable flexible waterproof layer, and its shape can be changed according to the shape requirements of the first protrusion 33, effectively filling the space between the first protrusion 33 and the second protrusion 412, and facilitating disassembly and maintenance.

[0039] In this embodiment, the sound guide hole is further provided with a hydrophobic dustproof mesh. The hydrophobic dustproof mesh is located on the side of the front shell assembly away from the speaker bracket and close to the waterproof and breathable membrane. Preferably, the hydrophobic dustproof mesh uses a superhydrophobic coating, which allows water droplets to form beads and slide off the mesh surface, preventing liquid from accumulating and seeping into the sound guide hole 32. At the same time, it can effectively intercept dust and sand particles in the air, preventing solid particles from clogging the sound guide hole 32 or entering the cavity, avoiding the decrease in sound wave transmission efficiency caused by dust accumulation in traditional solutions. This can further improve the waterproof and dustproof performance of the rugged mobile phone speaker structure and allow for fine-tuning of acoustic characteristics. In addition, the hydrophobic dustproof mesh is installed at an asymmetrical angle to the axis of the sound guide hole 32, guiding some sound waves to pass through the mesh in a grazing incidence manner, reducing the reflected energy when incident perpendicularly, and preventing the mesh and the micropores of the breathable membrane from forming a direct resonance, thus suppressing low-frequency humming noise.

[0040] In this embodiment, as Figure 1 As shown, the front shell assembly 3 has a mounting groove 31 on the side opposite to the speaker assembly 4. The mounting groove 31 is equipped with a button assembly 2. Preferably, the button assembly 2 is fixed to the mounting groove 31 by a snap or screw, and mates with a pre-reserved contact or guide post in the mounting groove 31 to achieve circuit conduction. In order to further enhance the stability and waterproof performance of the button assembly 2, a waterproof adhesive is provided between the button assembly 2 and the mounting groove 31, and the button assembly 2 is fixed to the mounting groove 31 by pressing or bonding process to achieve sealing and waterproofing. In addition, the waterproof adhesive can also be a waterproof material such as a silicone sealing ring that can be waterproofed.

[0041] Preferably, the mounting slot 31 is stepped, and the mounting slot 31 includes an integrally connected first slot 311 and second slot 312. The first slot 311 is provided with a button assembly 2, and the side of the second slot 312 opposite to the first slot 311 is connected to the sound guide hole 32. The cross-sectional width of the first slot 311 is greater than the cross-sectional width of the second slot 312, which not only meets the installation requirements and stability of the button assembly 2, but also ensures the smooth output of sound, thereby ensuring convenient operation while optimizing the sound output effect.

[0042] The assembly groove 31 is located on the outside of the front shell assembly 3, and is located on both sides of the front shell assembly 3, respectively, and the corresponding area is effectively sealed by sharing the waterproof backing adhesive 5, which significantly reduces the space occupied by the independent sealing structure and thus improves the space utilization rate.

[0043] Understandably, the waterproof adhesive 5 used for sealing the speaker sound guide hole 32 extends to the area of ​​the button assembly 2, forming a continuous waterproof boundary; that is, liquid must simultaneously penetrate the speaker sealing layer and the button sealing layer to intrude into the body. To further enhance the waterproof effect, sealing material can be filled into the gap between the button assembly 2 and the mounting groove 31, such as by using liquid silicone injection molding. This not only effectively blocks the entry of everyday liquids, but also allows the button assembly 2 to elastically deform when pressed to maintain its seal. In addition, if the button assembly 2 is damaged, it can be replaced separately without damaging the overall waterproof structure, facilitating future repairs and replacements.

[0044] In this embodiment, the button assembly 2 includes a DOME piece 22 (abbreviation for Metal dome switch) and a button cap 21; the DOME piece 22 is disposed in the assembly slot 31, and the button cap 21 is disposed in the DOME piece 22; preferably, the DOME piece 22 includes a circuit board, the circuit board is provided with a plurality of metal springs, and the button cap 21 is disposed corresponding to the metal springs.

[0045] Specifically, first, use waterproof adhesive to attach the DOME sheet 22 to the assembled front shell assembly 3, then install the button cap 21 on the DOME sheet 22. After that, inject white glue into the connection positions of the button cap 21, the DOME sheet 22, and the front shell assembly 3 to provide secondary protection and waterproofing to the back of the DOME sheet 22, preventing water from entering the circuit board from the back of the DOME sheet 22 and causing the button to malfunction or short circuit. Finally, install the button fixing piece 1 to fix the position of each button cap 21.

[0046] In this embodiment, a rear shell assembly is also included. The rear shell assembly and the front shell assembly 3 engage with each other to form a receiving cavity. The speaker assembly 4 is located in the receiving cavity to form a complete waterproof mechanism, further improving the waterproof effect and thus achieving the effect of waterproofing the entire machine.
