This application claims the priority benefit of Chinese Patent Application Serial Number 202311425683.0, filed on Oct. 30, 2023, the full disclosure of which is incorporated herein by reference.
The present application is related to a technical field of designing a waterproof speaker device, specifically focusing on a speaker device.
In the current market, waterproof speakers used in smartwatches and wearable devices are designed with separate structures for sealing and waterproofing. Due to the independent designs of these structures and the speaker itself, there is a lack of effective and proper integration between them. As a result, the overall waterproof performance of the speaker is compromised. Furthermore, when the waterproof structure of the speaker is submerged in water, the speaker itself needs to have enough structural strength to withstand external water pressure. Therefore, if the waterproof structure of the speaker is not appropriately integrated with the speaker structure and the speaker may endure less pressure, the speaker is susceptible to water seepage. Consequently, this vulnerability to external water pressure can lead to water leakage, resulting in potential damage to the internal components of the speaker.

In this embodiment, the bracket 151 of the vibration module 15 includes a frame body 1511 and multiple connection pillars 1512, there are four connection pillars 1512, each corresponding to one of the positions adjacent to the four corners of the frame body 1511, the frame body 1511 is disposed on the auxiliary magnetic 132, one end of the connection pillar 1512 extends downward from the frame body 1511 to the magnetic guide plate 11 to be fixed thereon. The frame body 1511 adjacent to the auxiliary magnetic guide component 134 has a bottom with a notch 15110, and the first bearing platform 1341 of the auxiliary magnetic guide component 134 embeds in the notch 15110. Furthermore, the outer side of the auxiliary magnetic guide component 134 has side notches 1340, and one end of the connection pillar 1512 passes through the corresponding side notch 1340, respectively. The auxiliary magnetic 132 has two sides, each with its respective notch 1320, and one end of the connection pillar 1512 passes through the notch 1320. The outer side of the magnetic guide plate 11 has plate notches 111, one end of the connection pillar 1512 passes through the plate notch 111 and is fixed on the bottom surface of the magnetic guide plate 11. The above- mentioned side notches 1340, notches 1320 and plate notches 111 are correspondingly interconnected, and one end of the connection pillar 1512 passes through the side notch 1340, notch 1320 and plate notch 111 sequentially and then is fixed. By fixing one end of the connection pillar 1512 of the bracket 151 of the vibration module 15 on the bottom of the magnetic guide plate 11, this embodiment enhances the overall structure strength of the speaker device 1 and raises the drop protection of the speaker device 1.
In this embodiment, the magnetic circuit 13 includes the main magnetic 131, auxiliary magnetic 132, main magnetic guide component 133 and auxiliary magnetic guide component 134, and the main magnetic guide component 133 and the auxiliary magnetic guide component 134 are used to concentrate the magnetic flux line of the main magnetic 131 and the auxiliary magnetic 132 to enhance the magnetic strength of the main magnetic 131 and the auxiliary magnetic 132. Furthermore, the main magnetic guide component 133 is a long plate structure corresponding to the rectangular structure of the main magnetic 131. The main magnetic guide component 133 serves as a structure to assist in strengthening the magnetic field of the main magnetic 131. The auxiliary magnetic guide component 134 not only can serve as a structure to assist in strengthening the magnetic field of the auxiliary magnetic 132, in addition, the annular structure of the auxiliary magnetic guide component 134 is corresponding to the annular structure of the bracket 151 of the vibration module 15, the auxiliary magnetic guide component 134 but also can serve as the auxiliary support structure of the vibration module 15.
In this embodiment, the frame body 1511 of the bracket 151 of the vibration module 15 includes a top wall 15111, an inner sidewall 15112 and an outer sidewall 15113, two sides of the top wall 15111 respectively connect to the inner sidewall 15112 and the outer sidewall 15113, the elastic support component 1522 includes a connection part 15221, an elastic part 15222 and a fixing part 15223, and the connection part 15221, elastic part 15222 and fixing part 15223 of the elastic support component 1522 are integrally formed. The inner side of the connection part 15221 surrounds the periphery of the diaphragm 1521, the outer side of the connection part 15221 connects to the inner side of the elastic part 15222, the outer side of the elastic part 15222 connects to the inner side of the fixing part 15223, and the fixing part 15223 is injection-molded onto the inner sidewall 15112, top wall 15111 and outer sidewall 15113. In this embodiment, the elastic support component 1522 not only serves as the waterproof outer layer of the speaker device 1, but also serves as the vibration sound-producing structure for the speaker device 1. The elastic support component 1522 of the vibration component 152 is manufactured by injection-molding onto the frame body 1511 of the bracket 151.
As the abovementioned, the fixing part 15223 serves as the structure to secure the elastic support component 1522 onto the frame body 1511. The fixing part 15223 is molded onto the inner sidewall 15112, top wall 15111 and outer sidewall 15113 in which the outer sidewall 15113 includes a first recess 15114, and the fixing part 15223 covers the first recess 15114. The outer sidewall 15113 further includes a second recess 15115, the second recess 15115 is located in the first recess 15114, and the second recess 15115 is adjacent to the top wall 15111. The first recess 15114 and the second recess 15115 are disposed in a stepped configuration. When the fixing part 15223 surrounds the outer sidewall 15113 and first recess 15114 of the frame body 1511, in addition to the increased contact area with the outer sidewall 15113, the structure of fixing part 15223 being secured to the non-planar outer sidewall 15113 can also provide stress in non-uniform directions. This facilitates the placement of fixing part 15223 on the outer sidewall 15113 of the frame body 1511. Furthermore, the fixing part 15223 simultaneously surrounds the top wall 15111 and the inner sidewall 15112 fixed on the different plane of the frame body 1511, and the fixing part 15223 has a good fixing effect and strength for the frame body 1511.
Additionally, one side of the fixing part 15223 corresponding to the outer sidewall 15113 includes a protrusion part 15224, wherein the protrusion part 15224 includes a convex surface 15225, a first side surface 15226 and a second side surface 15227, the first side surface 15226 and the second side surface 15227 are located on two sides of the convex surface 15225, and the first side surface 15226 and the second side surface 15227 are symmetrically disposed relative to the convex surface 15225 so that the convex surface 15225, first side surface 15226 and second side surface 15227 can disperse the compressive pressure applied from the outside to the inside of the speaker device 1. This disperses the external pressure onto the first side surface 15226 and the second side surface 15227 relative to the convex surface 15225, thereby relieving the internal pressure on the speaker device 1.
In this embodiment, the inner sidewall 15112 includes a third recess 15116, the elastic part 15222 of the elastic support component 1522 has the largest tensile toughness, the outer side of the elastic part 15222 of the elastic support component 1522 includes a first elastic connection part 15228 and a second elastic connection part 15229, the first elastic connection part 15228 extends and attaches toward the recess bottom and recess wall of the third recess 15116, the second elastic connection part 15229 extends and attaches toward above of the sidewall of the third recess 15116, and the second elastic connection part 15229 is connected to the fixing part 15223. When the first clastic connection part 15228 and second elastic connection part 15229 of the elastic part 15222 are fixed on the inner sidewall 15112, the first elastic connection part 15228 and the second elastic connection part 15229 can provide fixed stresses from two directions, making the elastic part 15222 fix stably on the inner sidewall 15112.
Furthermore, the inner side of the connection part 15221 of the elastic support component 1522 surrounds the periphery of the diaphragm 1521, the connection part 15221 extends and attaches the top surface of the diaphragm 1521, the thickness of the connection part 15221 located at a center of the diaphragm 1521 is thinner than the thickness of the connection part 15221 located at the periphery of the diaphragm 1521, therefore, the sound can be emitted from the diaphragm 1521 smoothly, and the structure strength of the elastic support component 1522 and diaphragm 1521 can be enhanced. Still more, the connection part 15221 extends and attaches the bottom periphery of the diaphragm 1521 so that the fixing strength between the elastic support component 1522 and the diaphragm 1521 is strong.

Furthermore, the first bearing platform 1341 further includes a first protrusion platform 13411 and a second protrusion platform 13412, a height from the top surface of the second protrusion platform 13412 to the top surface of the auxiliary magnetic 132 is higher than a height from the top surface of the first protrusion platform 13411 to the top surface of the auxiliary magnetic 132. In other words, a vertical height from the top surface of the first protrusion platform 13411 to the bottom surface of the elastic support component 1522 is higher than a vertical height from the top surface of the second protrusion platform 13412 to the bottom surface of the elastic support component 1522. The top surface of the first protrusion platform 13411 is inclined and connected to the top surface of the second protrusion platform 13412. The abovementioned illustrates the distance from the top surface of the second protrusion platform 13412 to the bottom surface of the elastic support component 1522 is shorter. If the elastic part 15222 of the elastic support component 1522 is similarly subjected to pressure causing inward concavity, the top surface of the second protrusion platform 13412 will first support the bottom surface of the clastic part 15222, subsequently, the side surface will support the bottom surface of the elastic part 15222, and finally, the top surface of the first protrusion platform 13411 will support the bottom surface of the elastic part 15222. The abovementioned method gradually transfers the pressure from the bottom surface of the elastic part 15222 to the first bearing platform 1341 and guides the pressure of the bottom surface of the elastic part 15222 in an inward direction, making the stress concentrate towards the diaphragm 1521. In this embodiment, the vertical height H1 from the top surface of the second protrusion platform 13412 to the top surface of the first protrusion platform 13411 is larger than or equal to half of the vertical height H2 from the bottom surface of the elastic part 15222 to the bottom surface of the diaphragm 1521. Thus, by limiting the amplitude of the diaphragm 1521 relative to the elastic part 15222, the height difference between the top surface of the first protrusion platform 13411 and the top surface of the second protrusion platform 13412 is restricted.

Furthermore, the inner side of the auxiliary magnetic guide component 134 has a circuit notch 1343, and one end of the conductive circuit 172 passes through the circuit notch 1343 to connect to the voice coil 153. This is beneficial for the conductive circuit 172 passing through the auxiliary magnetic guide component 134 to connect to the voice coil 153 to avoid the condition that the voice coil 153 vibrates and interacts with the conductive circuit 172 to make the conductive circuit 172 produce vibration. The circuit notch 1343 can reduce the vibration of the conductive circuit 172 subjects to the interference of the auxiliary magnetic guide component 134, and thus avoid the conductive circuit 172 in turn affects the vibration of the voice coil 153. In this embodiment, when the voice coil 153 receives power to change the magnetic field, the voice coil 153 interacts with the magnetic circuit 13 to make the voice coil 153 produce vibration, driving the diaphragm 1521 and the elastic support component 1522 of the vibration component 152 vibrate, and thus the diaphragm 1521 produces sound via vibration.
In summary, the present application provides a speaker device, by positioning the first protrusion platform 13411 and second protrusion platform 13412 of the first bearing platform 1341 under the elastic support component 1522, the distance from the first bearing platform 1341 to the elastic support component 1522 is less than half the amplitude of the vibration component 152 of the speaker device 1. When the elastic support component 1522 undergoes inward concave deformation due to external pressure, the first protrusion platform 13411 and the second protrusion platform 13412 of the first bearing platform 1341 support the bottom of the elastic support component 1522 so that the first bearing platform 1341 can enhance the outward supporting strength of the elastic support component.
It is to be understood that the term “comprises”, “comprising”, or any other variants thereof, is intended to encompass a non-exclusive inclusion, such that a process, method, article, or device of a series of elements not only include those elements but also comprises other elements that are not explicitly listed, or elements that are inherent to such a process, method, article, or device. An element defined by the phrase “comprising a . . . ” does not exclude the presence of the same element in the process, method, article, or device that comprises the element.
Although the present invention has been explained in relation to its preferred embodiment, it does not intend to limit the present invention. It will be apparent to those skilled in the art having regard to this present invention that other modifications of the exemplary embodiments beyond those embodiments specifically described here may be made without departing from the spirit of the invention.
