Description

Technical Field

[0001] The present invention relates to a sound - generating device, and particularly to an embedded sound effect device and a sound quality improvement method. Background Art

[0002] Wall switches or wall sockets are indispensable electrical devices in usage environments such as home environments and hotel environments. A wall switch or a wall socket includes a back box and a panel. During home decoration or hotel decoration, first, a receiving groove is dug on the wall (the size and shape of the receiving groove match the size and shape of the back box. For example, the back box can be, but is not limited to, an 86 - type back box). Secondly, the back box is installed and fixed in the receiving groove on the wall. Then, after wiring is completed, the panel is installed on the back box so that only the panel is exposed on the wall. Wall switches or wall sockets are practical and aesthetic for usage environments such as home environments and hotel environments.

[0003] A speaker is an electro - acoustic conversion device that can be driven by electric energy to vibrate and generate sound in response to the input of an audio signal. When a user uses a speaker, for example, when the user uses a speaker near a television in order to improve the sound quality effect of the television, the user usually places two speakers symmetrically on both sides of the television. This way easily causes an undesirable phenomenon of "displacement" when the speakers vibrate and generate sound, and the more the speakers are used to improve the bass sound effect, the more obvious the "displacement" phenomenon is. However, once the undesirable phenomenon of "displacement" occurs in the speakers, it will inevitably reduce the sound quality effect of the speakers. In addition, when the speakers are placed in the usage environment for use, the speakers will occupy a certain space. Especially for users with a relatively small usage space, the speakers that need to occupy a certain space will bring some usage troubles to the users. Summary of the Invention

[0046] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention.

It is only for the convenience of describing the present invention 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. Therefore, the above terms should not be construed as limiting the present invention.

[0048] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of the element can be multiple. The term "a" should not be construed as limiting the quantity.

[0049] Referring to the appended drawings of the specification of the present invention Figures 1 to 3 , a built-in sound device 100 according to a preferred embodiment of the present invention is disclosed and described in the following. The built-in sound device 100 includes a cassette 10 and a sound generating part 20 disposed in the cassette 10. The built-in sound device 100 can be embedded in the sound enclosure 200 in such a way that the cassette 10 is embedded inside the sound enclosure 200.

[0050] Specifically, the cassette 10 includes a bottom wall 11 and a side wall 12 extending from the periphery of the bottom wall 11 to define a vibration cavity 13 of the cassette 10 between the bottom plate 11 and the side wall 12, and an opening 14 of the cassette 10 defined by the side wall 12, wherein the opening 14 communicates with the vibration cavity 13. Preferably, the side wall 12 of the cassette 10 extends integrally from the periphery of the bottom wall 11. For example, the cassette 10 can be an integrally molded injection-molded part, so that the side wall 12 extends integrally from the periphery of the bottom wall 11, and the vibration cavity 13 and the opening 14 of the cassette 10 are formed while the cassette 10 is molded.

[0051] The sound generating part 20 is mounted on the side wall 12 of the cassette 10, and the sound generating part 20 closes the opening 14 of the cassette 10. Preferably, the sound generating part 20 is a sound generating module, wherein the sound generating part 20 includes a mounting plate 21 and at least one main vibration speaker 22 and at least one passive vibrator 23 respectively disposed on the mounting plate 21. The sound generating part 20 is mounted on the side wall 12 of the cassette 10 in such a way that the mounting plate 21 closes the opening 14 of the cassette 10 and the main vibration speaker 22 and the passive vibrator 23 share the vibration cavity 13 of the cassette 10. In this way, when the main vibration speaker 22 vibrates and generates sound in response to the input of an audio signal, the passive vibrator 23 can vibrate in response to the vibration of the main vibration speaker 22 to generate auxiliary sound effects, thereby enhancing the sound quality of the inlaid sound device 100. Optionally, in other examples of the inlaid sound device 100, the sound generating part 20 may only include the mounting plate 21 and the main vibration speaker 22 disposed on the mounting plate 21, refer to the attached Figure 7A and Figure 7B .

[0052] Preferably, the size and shape of the mounting plate 21 are the same as those of the cassette 10, so that the mounting plate 21 can close the opening 14 of the cassette 10. For example, in the attached Figures 1 to 3In this preferred example of the embedded sound device 100 shown, the cassette 10 is a square cassette. Correspondingly, the mounting plate 21 is a square mounting plate, and the length and width dimensions of the mounting plate 21 are greater than or equal to the length and width dimensions of the cassette 10, so that the mounting plate 21 mounted on the side wall 12 of the cassette 10 can close the opening 14 of the cassette 10. More preferably, the length and width dimensions of the mounting plate 21 are greater than the length and width dimensions of the cassette 10, so that after the mounting plate 21 is mounted on the side wall 12 of the cassette 10 to close the opening 14 of the cassette 10, each side of the mounting plate 21 can protrude from the side wall 12 of the cassette 10.

[0053] Optionally, in other examples of the embedded sound device 100, the cassette 10 is a circular cassette. Correspondingly, the mounting plate 21 is a circular mounting plate, and the diameter of the mounting plate 21 is greater than or equal to the diameter of the cassette 10, so that the mounting plate 21 mounted on the side wall 12 of the cassette 10 can close the opening 14 of the cassette 10. Refer to the attached Figure 7A and Figure 7B . Optionally, in other examples of the embedded sound device 100, the cassette 10 is a circular cassette, while the mounting plate 21 is a square mounting plate, and the length and width dimensions of the mounting plate 21 are greater than or equal to the diameter of the cassette 10, so that the mounting plate 21 mounted on the side wall 12 of the cassette 10 can close the opening 14 of the cassette 10. Optionally, in other examples of the embedded sound device 100, the cassette 10 can also be but is not limited to an oval cassette, a polygonal cassette, etc.

[0054] Continuing to refer to the attached Figures 1 to 3 , the mounting plate 21 has a front surface 211 and a back surface 212 corresponding to the front surface 211. After the mounting plate 21 is mounted on the side wall 12 of the cassette 10, the back surface 212 of the mounting plate 21 faces the vibration cavity 13 of the cassette 10, and the front surface 211 of the mounting plate 21 is exposed outside the cassette 10.

[0055] The mounting plate 21 further has at least one speaker hole 213 and at least one vibrator hole 214. The speaker hole 213 and the vibrator hole 214 respectively extend from the front surface 211 of the mounting plate 21 to the back surface 212 to penetrate the mounting plate 21. For example, the mounting plate 21 can be an injection molded part, and the speaker hole 213 and the vibrator hole 214 of the mounting plate 21 are formed while the mounting plate 21 is being molded.

[0056] The main vibration speaker 22 includes a driving diaphragm 221, a driving surround 222, a voice coil 223, and a magnetic circuit system 224. The outer and inner sides of the driving surround 222 respectively extend to be connected to the mounting plate 21 and the driving diaphragm 221. The high end of the voice coil 223 is connected to the driving diaphragm 221, the low end of the voice coil 223 extends in a direction away from the back surface 212 of the mounting plate 21, and the low end of the voice coil 223 is coupled to the magnetic circuit system 224. The main vibration speaker 22 is thus arranged on the mounting plate 21. When the main vibration speaker 22 responds to the input of an audio signal, the magnetic circuit system 224 can drive the driving diaphragm 221 to vibrate reciprocally through the voice coil 223 to generate sound effects, and the driving surround 222 is used to limit the stroke of the driving diaphragm 221 and ensure that the driving diaphragm 221 vibrates reciprocally along the central axis of the main vibration speaker 22.

[0057] Preferably, the driving surround 222 of the main vibration speaker 22 is integrally bonded to the mounting plate 21 and the driving diaphragm 221 during molding. In this way, the bonding consistency between the driving surround 222 and the mounting plate 21 and the bonding consistency between the driving surround 222 and the driving diaphragm 221 can be ensured in the circumferential direction of the main vibration speaker 22. For example, during the manufacturing process of the inlaid sound effect device 100, first, the mounting plate 21 and the driving diaphragm 221 are placed in a molding die in such a way that the driving diaphragm 221 is held in the speaker hole 213 of the mounting plate 21. Second, a molding material (such as a rubber material) is added to the molding die, and after the molding material is cured, the driving surround 222 extending between the mounting plate 21 and the driving diaphragm 221 is formed, so that the driving surround 222 is integrally bonded to the mounting plate 21 and the driving diaphragm 221 during molding. Optionally, the outer side of the driving surround 222 of the main vibration speaker 22 is bonded to the mounting plate 21 by glue or a similar adhesive.

[0058] Further, the main vibration speaker 22 includes a speaker frame 225, wherein the magnetic circuit system 224 is disposed in the speaker frame 225, and the speaker frame 225 is mounted on the back surface 212 of the mounting plate 21, so that the magnetic circuit system 224 can be reliably and stably held by the speaker frame 225 on one side of the mounting plate 21. The manner in which the magnetic circuit system 224 is disposed in the speaker frame 225 is not limited in the embedded sound effect device 100 of the present invention. For example, the magnetic circuit system 224 can be mounted in the speaker frame 225, or the magnetic circuit system 224 can be wrapped when the speaker frame 225 is injection molded, so that the magnetic circuit system 224 is disposed in the speaker frame 225.

[0059] Furthermore, the speaker frame 225 has at least one insertion hole 2251. Correspondingly, the mounting plate 21 has at least one insertion leg 215, and these insertion legs 215 respectively extend from the back surface 212 of the mounting plate 21. Each insertion leg 215 of the mounting plate 21 is respectively inserted into each insertion hole 2251 of the speaker frame 225 to reliably mount the speaker frame 225 on the back surface 212 of the mounting plate 21.

[0060] The passive vibrator 23 includes a passive diaphragm 231 and a passive surround 232. The outer side and the inner side of the passive surround 232 respectively extend to be connected to the mounting plate 21 and the passive diaphragm 231, so that the passive vibrator 23 is disposed on the mounting plate 21. When the main vibration speaker 22 vibrates and emits sound in response to the input of an audio signal, the passive vibrator 23 can cause the passive diaphragm 231 to vibrate reciprocally along the central axis of the passive vibrator 23 in response to the vibration of the main vibration speaker 22 to generate auxiliary sound effects, wherein the passive surround 232 is used to limit the stroke of the passive diaphragm 231 and ensure that the passive diaphragm 231 vibrates reciprocally along the central axis of the passive vibrator 23.

[0061] Preferably, the passive suspension edge 232 of the passive vibrator 23 is integrally bonded to the mounting plate 21 and the passive diaphragm 231 during molding. In this way, the bonding consistency between the passive suspension edge 232 and the mounting plate 21 and the bonding consistency between the passive suspension edge 232 and the passive diaphragm 231 can be ensured in the circumferential direction of the passive vibrator 23. For example, during the manufacturing process of the inlaid sound effect device 100, first, the mounting plate 21 and the weight 233 are placed in the molding die in such a way that a weight 233 is held in the vibrator hole 214 of the mounting plate 21. Second, the molding material is added to the molding die, and after the molding material is cured, the weight 233 and a part of the molding material wrapping the weight 233 form the passive diaphragm 231, and another part of the molding material forms the passive suspension edge 232 extending between the mounting plate 21 and the passive diaphragm 231, so that the passive suspension edge 232 is integrally bonded to the mounting plate 21 and the passive diaphragm 231 during molding. Optionally, the outer side of the passive suspension edge 232 of the passive vibrator 23 is bonded to the mounting plate 21 by glue or a similar adhesive.

[0062] It should be noted that naming the diaphragm of the main vibration speaker 22 as the active diaphragm 221 and the suspension edge as the active suspension edge 222, and naming the diaphragm of the passive vibrator 23 as the passive diaphragm 231 and the suspension edge as the passive suspension edge 232 is to facilitate the distinction between the diaphragms and suspension edges of the active vibrator 22 and the passive vibrator 23 to avoid confusion. It should be understood that the specific names of the diaphragms and suspension edges of the main vibration speaker 22 and the passive vibrator 23 do not constitute a limitation on the content and scope of the inlaid sound effect device 100 of the present invention. For example, the active diaphragm 221 of the main vibration speaker 22 itself does not reciprocate along the central axis of the main vibration speaker 22, but reciprocates along the central axis of the main vibration speaker 22 when the magnetic return system 224 and the voice coil 223 of the main vibration speaker 22 cooperate to provide driving force.

[0063] Continue to refer to the attached Figures 1 to 3 , the mounting plate 21 is a square mounting plate, which has four corner portions. The four corner portions of the mounting plate 21 are sequentially named a first corner portion 2101, a second corner portion 2102, a third corner portion 2103, and a fourth corner portion 2104. The first corner portion 2101 and the third corner portion 2103 correspond to each other, and the second corner portion 2102 and the fourth corner portion 2104 correspond to each other. The main vibration speaker 22 and the passive vibrator 23 are respectively disposed at two corresponding corner portions of the mounting plate 21. For example, in the attachedFigures 1 to 3 In this specific example of the embedded sound device 100 shown, the main vibration speaker 22 is disposed at the second corner portion 2102 of the mounting plate 21, and the passive vibrator 23 is disposed at the fourth corner portion 2104 of the mounting plate 21, so that the main vibration speaker 22 and the passive vibrator 23 are respectively disposed at two corresponding corner portions of the mounting plate 21. Optionally, if the main vibration speaker 22 is disposed at the first corner portion 2101 of the mounting plate 21, then the passive vibrator 23 is disposed at the third corner portion 2103 of the mounting plate 21, so that the main vibration speaker 22 and the passive vibrator 23 are respectively disposed at two corresponding corner portions of the mounting plate 21.

[0064] In the Figures 1 to 3 In this preferred example of the embedded sound device 100 shown, by disposing the main vibration speaker 22 and the passive vibrator 23 at two corresponding corner portions of the mounting plate 21, it is possible to dispose the larger-sized main vibration speaker 22 and the passive vibrator 23 on the limited area of the mounting plate 21, thereby improving the sound quality effect of the embedded sound device 100.

[0065] Continuing to refer to the Figures 1 to 3 , the embedded sound device 100 further includes a vibration damping portion 30, wherein the vibration damping portion 30 is held between the mounting plate 21 of the sound generating portion 20 and the side wall 12 of the recessed box 10, so that when the main vibration speaker 22 and the passive vibrator 23 vibrate to generate sound effects in the sound generating portion 20, the vibration damping portion 30 can prevent the vibrations generated by the main vibration speaker 22 and the passive vibrator 23 from being transmitted to the recessed box 10 through the mounting plate 21, thereby improving the sound quality effect of the embedded sound device 100.

[0066] Preferably, the vibration damping portion 30 is a rubber vibration damping portion, wherein after the mounting plate 21 is mounted on the side wall 12 of the recessed box 10, the vibration damping portion 30 can be held between the mounting plate 21 and the side wall 12 of the recessed box 10 to prevent the vibrations generated by the main vibration speaker 22 and the passive vibrator 23 from being transmitted to the recessed box 10 through the mounting plate 21 by absorbing vibrations, thereby improving the sound quality effect of the embedded sound device 100.

[0067] Specifically, the vibration damping portion 30 includes an annular vibration damping element 31, wherein the vibration damping element 31 is disposed along the peripheral edge of the mounting plate 21 on the back surface 212 of the mounting plate 21, so that after the mounting plate 21 is mounted on the side wall 12 of the recessed box 10, the vibration damping element 31 can be held between the mounting plate 21 and the side wall 12 of the recessed box 10. Optionally, the vibration damping element 31 is disposed along the side wall 12 of the recessed box 10, so that after the mounting plate 21 is mounted on the side wall 12 of the recessed box 10, the vibration damping element 31 can be held between the mounting plate 21 and the side wall 12 of the recessed box 10.

[0068] Preferably, the side wall 12 of the recessed box 10 has a retaining groove 121, wherein at least a part of the vibration damping element 31 can be held in the retaining groove 121 of the side wall 12 to ensure that the vibration damping element 31 can be reliably held between the mounting plate 21 and the side wall 12 of the recessed box 10.

[0069] The mounting plate 21 has a series of retaining holes 215, which extend from the back surface 212 to the front surface 211 of the mounting plate 21 at intervals along the peripheral edge of the mounting plate 21. The vibration damping portion 30 further includes a series of retaining elements 32, which extend at intervals on the vibration damping element 31. The retaining elements 32 of the vibration damping portion 30 are respectively held in the retaining holes 215 of the mounting plate 21, so that the vibration damping element 31 is disposed along the peripheral edge of the mounting plate 21 on the back surface 212 of the mounting plate 21. Preferably, the retaining holes 215 of the mounting plate 21 are through holes to allow the retaining elements 32 of the vibration damping portion 30 to extend from the back surface 212 to the front surface 211 through the retaining holes 215.

[0085] Secondly, install the cassette 10 of the inlaid sound device 100 through the cavity opening of the fixed box into the fixed cavity of the fixed box, and an absorption vibration part 300 can be formed between the cassette 10 and the fixed box. For example, filling substances such as sound-absorbing cotton between the cassette 10 and the fixed box can form the absorption vibration part 300.

[0086] Thirdly, connect the power cord and the audio cable to the wiring mechanism 45 of the electric control part 40.

[0087] Fourthly, install the mounting plate 21 of the sound generating part 20 on the cassette 10, where the mounting plate 21 closes the opening 14 of the cassette 10, and the main vibration speaker 22 and the passive vibrator 23 share the vibration cavity 13 of the cassette 10.

[0088] Fifthly, install the panel 50 on the mounting plate 21 so that the panel 50 covers the main vibration speaker 22 and the passive vibrator 23 of the sound generating part 20, and allows the control switch 42 of the electric control part 40 to be exposed to the outside of the panel 50 through the operation channel 52 of the panel 50.
