Description

Technical Field

[0001] The present invention relates to the field of sound, and in particular to a loudspeaker capable of generating low frequencies and an assembly method thereof. Background Art

[0002] Both sound waves and electrical signals are carriers of information, where information is transmitted with the propagation of sound waves and with the transmission of electrical signals. Although both sound waves and electrical signals can be used as carriers of information, the difference in carriers determines that humans need to perceive this information in different ways. For example, for sound wave carriers, humans can perceive the information carried by sound waves based on their own physiological functions. Specifically, when the frequency range of sound waves is between 20Hz and 20,000Hz, the unique physiological structure of the human ear and brain enables humans to perceive the information carried by sound waves. For electrical signal carriers, humans need to use some means to perceive this information through, but not limited to, hearing, vision, etc. Specifically, humans can use speakers to convert electrical signals into sound waves to perceive the information carried by electrical signals through hearing, or humans can use electronic devices (such as computers, smart phones, etc.) to convert electrical signals into text, pictures, videos, etc. to perceive the information carried by electrical signals through vision. It is understandable that for the same type of carrier, the means by which humans perceive the information carried by the carrier depends on the type of information. For example, when the information carried by the electrical signal is music, humans can choose a speaker to convert the electrical signal into sound waves to allow humans to more accurately perceive and understand the music content in an auditory way. In other words, a speaker is a transducer that can convert electrical signals into sound waves, so that when the sound waves are transmitted to the human ear, based on human physiological functions, humans can perceive and understand the information carried by the electrical signal.

[0003] Figures 1A to 1CThe conventional loudspeaker is shown, which includes a frame 10P, a magnetic return system 20P, a voice coil 30P, a spring 40P, a suspension 50P and a vibration plate 60P. The frame 10P has a high end portion 11P and a low end portion 12P corresponding to the high end portion 11P. The magnetic return system 20P is arranged at the low end portion 12P of the frame 10P. The suspension outer side 51P and the suspension inner side 52P of the suspension 50P extend respectively to be connected to the high end portion 11P of the frame 10P and the vibration plate 60P. P, thereby the vibration plate 60P is maintained at the high end 11P of the frame 10P by the suspension 50P, and the frame 10P surrounds the vibration plate 60P, the high end 31P of the voice coil 30P extends to and is connected to the vibration plate 60P, the low end 32P of the voice coil 30P is magnetically connected to the magnetic return system 20P, the elastic wave 40P is arranged inside the frame 10P, and the elastic wave outer side 41P and the elastic wave inner side 42P of the elastic wave 40P respectively extend to be connected to the frame 10P and the voice coil 30P. When an electrical signal is input into the loudspeaker, based on the electromagnetic principle, the magnetic return system 20P can drive the voice coil 30P to reciprocate, so that the voice coil 30P drives the vibration plate 60P to reciprocate and stir the air to generate sound waves, wherein the suspension 50P is designed to limit the stroke of the vibration plate 60P, and the suspension 50P and the elastic wave 40P are designed to cooperate with each other to ensure that the voice coil 30P reciprocates along the axial direction when driven by the magnetic return system 20P. In this way, on the one hand, the vibration plate 60P can be ensured to reciprocate along the axial direction, and on the other hand, the voice coil lower end 32P of the voice coil 30P can be prevented from touching the magnetic return system 20P due to the deviation of the voice coil 30P from the axial direction. It can be understood by those skilled in the art that, for a speaker, the stroke and frequency of the vibration plate 60P determine the frequency of the sound waves that the speaker can generate. Specifically, if the stroke of the vibration plate 60P is smaller and the frequency is higher, the frequency of the sound waves that the speaker can generate is higher, and the speaker can be called a high-frequency speaker. If the stroke of the vibration plate 60P is larger and the frequency is lower, the frequency that the speaker can generate is lower, and the speaker can be called a low-frequency speaker. Compared with high-frequency speakers, low-frequency speakers require the vibration plate 60P to have a larger stroke, which means that the vibration plate 60P is more likely to deflect during the driving process, which affects the sound quality and life of the speaker.

[0004] Specifically, in the existing loudspeaker, since the high end 31P of the voice coil 30P is connected to the vibration plate 60P, the voice coil 30P and the vibration plate 60P form a linkage mechanism, and the characteristic of the linkage mechanism is that once any one of the voice coil 30P and the vibration plate 60P deviates from the axial direction during movement, the other one will inevitably deviate from the central axis. Therefore, the existing loudspeaker uses the following method to ensure that the vibration direction of the linkage mechanism is in the axial direction: the two sides of the elastic wave 40P are respectively extended to and connected to the voice coil 30P and the frame 10P in order to limit the movement direction of the voice coil 30P to the axial direction, and the two sides of the suspension edge 50P are respectively extended to and connected to the vibration plate 60P and the frame 10P in order to limit the movement direction of the vibration plate 60P to the axial direction. However, in the existing structure of the speaker, the elastic wave 40P is maintained between the magnetic return system 20P and the suspension 50P, which means that the connection position of the elastic wave 40P and the linkage mechanism (the connection position of the elastic wave 40P and the voice coil 30P) and the connection position of the suspension 50P and the linkage mechanism (the connection position of the suspension 50P and the vibration plate 60P) are close to each other. This feature of the elastic wave 40P, the suspension 50P and the linkage mechanism causes the elastic wave 40P and the suspension 50P to fail to play the expected role of limiting the movement direction of the linkage mechanism.

[0005] In other words, in the existing speaker, although the suspension 50P is connected to one end of the linkage mechanism, in order to ensure that the voice coil 30P and the magnetic return system 20P can have normal magnetic exchange, the connection position between the elastic wave 40P and the voice coil 30P is closer to the connection position between the suspension 50P and the vibration plate 60P, which causes the elastic wave 40P to be maintained between the magnetic return system 20P and the suspension 50P, which means that the connection position between the elastic wave 40P and the linkage mechanism (the connection position between the elastic wave 40P and the voice coil 30P) and the connection position between the suspension 50P and the linkage mechanism (the connection position between the suspension 50P and the vibration plate 60P) are close to each other, resulting in the elastic wave 40P and the suspension 50P being unable to play the expected role of limiting the movement direction of the linkage mechanism.

[0075] According to the claims and contents disclosed in the specification of the present invention, the technical solution of the present invention is specifically described as follows.

[0076] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0077] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0078] With reference to the accompanying drawings of the present invention Figures 2A to 4 A loudspeaker according to a preferred embodiment of the present invention is disclosed and explained in the following description, wherein the loudspeaker includes a frame 10, a magnetic return system 20, a drum-paper unit 30, a voice coil 40 and a stabilizing axis unit 50.

[0079] The magnetic return system 20 is arranged on the frame 10. The drum-paper unit 30 includes a diaphragm element 31 and a suspension edge 32 extending from the diaphragm element 31 to the frame 10. One end of the voice coil 40 is connected to the diaphragm element 31, and the other end of the voice coil 40 is drivably connected to the magnetic return system 20. The axis stabilizing unit 50 includes a linkage portion 51 and an axis stabilizing portion 52, one end of the linkage portion 51 is connected to the diaphragm element 31, and both sides of the axis stabilizing portion 52 extend to be connected to the frame 10 and the other end of the linkage portion 51.

[0080] When an electrical signal (audio signal) is connected to the speaker, based on the electromagnetic principle, the magnetic return system 20 can drive the voice coil 40 to vibrate back and forth along the axial direction of the speaker, so that the voice coil 40 drives the diaphragm element 31 to vibrate back and forth synchronously along the axial direction of the speaker to agitate the air and generate sound waves. In this process, on the one hand, the suspension 32 is configured to limit the reciprocating vibration of the diaphragm element 31 in the axial direction of the speaker and to limit the stroke of the diaphragm element 31, that is, when the diaphragm element 31 is driven to move in a direction away from the magnetic return system 20, the suspension 32 can prevent the movement direction of the diaphragm element 31 from deviating from the axial direction of the speaker while pulling the diaphragm element 31, so that the diaphragm element 31 has a tendency to move in the direction of the magnetic return system 20. Accordingly, when the diaphragm element 31 is driven to move in the direction of the magnetic return system 20, the suspension 32 can prevent the movement direction of the diaphragm element 31 from deviating from the axial direction of the speaker while pulling the diaphragm element 31, so that the diaphragm element 31 has a tendency to move in the direction away from the magnetic return system 20. On the other hand, the diaphragm element 31 can drive the linkage portion 51 to reciprocate along the axial direction of the speaker, and the diaphragm element 31 and the axis stabilizing portion 52 Different ends of the linkage portion 51 prevent the movement of the linkage portion 51 from deviating from the axial direction of the speaker, thereby preventing the vibration direction of the diaphragm element 31 from deviating from the axial direction of the speaker.

[0081] In the attached Figures 2A to 4 In this preferred example of the speaker shown, the diaphragm element 31 of the drum-paper unit 30 and the linkage part 52 of the stabilizing axis unit 50 form a linkage mechanism 200, that is, the diaphragm element 31 and the linkage part 52 of the linkage mechanism 200 reciprocate synchronously along the same direction. For example, in the present invention, the diaphragm element 31 and the linkage part 52 of the linkage mechanism can be restricted by the suspension edge 32 and the stabilizing axis part 52 and reciprocate synchronously along the axial direction of the speaker.

[0082] Reference Figures 2A to 4, the hanging edge 32 and the linkage part 51 are respectively located on different sides of the magnetic return system 20, so that the connection position between the hanging edge 32 and the linkage mechanism 200 (the connection position between the hanging edge 32 and the diaphragm element 31) and the connection position between the stabilizing axis part 52 and the linkage mechanism 200 (the connection position between the stabilizing axis part 52 and the linkage part 52) ​​can be far away, in this way, the reciprocating direction of the linkage mechanism 200 can be reliably maintained in the axial direction of the speaker, thereby reliably ensuring the sound quality of the speaker. Preferably, the hanging edge 32 is connected to one end of the linkage mechanism 200, and the stabilizing axis part 52 is connected to the other end of the linkage mechanism 200, so that the hanging edge 32 and the stabilizing axis part 52 can limit the movement direction of the linkage mechanism 200 at different ends of the linkage mechanism 200, thereby avoiding the deflection of the linkage mechanism 200.

[0086] Preferably, the magnetic return system 20 is disposed in the frame space 101 of the frame 10 in a manner that an outer wall of the magnetic return system 20 is fixedly mounted on an inner wall of the frame 10 .

[0087] More preferably, the magnetic gap 201 of the magnetic loop system 20 is annular, and on the same horizontal plane, the distance D1 between the central axis 100 of the speaker and any two points of the inner wall 203 of the magnetic loop system 20 used to form the magnetic gap 201 is equal. Correspondingly, on the same horizontal plane, the distance D2 between the central axis 100 of the speaker and any two points of the outer wall 204 of the magnetic loop system 20 used to form the magnetic gap 201 is equal, and the value of parameter D2 is greater than the value of parameter D1, so that there is a gap between the inner wall 203 and the outer wall 204 of the magnetic loop system 20, so that the magnetic loop system 20 defines the magnetic gap 201 and the magnetic gap opening 202 between the inner wall 203 and the outer wall 204.

[0088] The suspension edge 32 has a suspension edge outer side 321 and a suspension edge inner side 322 corresponding to the suspension edge outer side 321 , wherein the suspension edge outer side 321 and the suspension edge inner side 322 of the suspension edge 32 extend respectively to be connected to the frame 10 and the diaphragm element 31 , so as to maintain the diaphragm element 31 at the high end opening 102 of the frame 10 by the suspension edge 32 .

[0089] It is worth mentioning that the connection method between the outer side 321 of the suspension 32 and the frame 10 and the connection method between the inner side 322 of the suspension 32 and the diaphragm element 31 are not limited in the speaker of the present invention.

[0090] For example, in a preferred example of the speaker of the present invention, the suspension edge 32 is prefabricated, and the suspension edge outer side 321 of the suspension edge 32 is connected to the frame 10 by using an adhesive material such as glue, and the suspension edge inner side 322 of the suspension edge 32 is connected to the diaphragm element 31 by using an adhesive material such as glue, so that the suspension edge outer side 321 and the suspension edge inner side 322 of the suspension edge 32 are respectively connected to the frame 10 and the diaphragm element 31, so that the diaphragm element 31 is maintained at the high end opening 102 of the frame 10 by the suspension edge 32.

[0091] For example, in the attached Figures 2A to 4In this preferred example of the speaker shown, the suspension edge 32 is integrally formed between the frame 10 and the diaphragm element 31, so that the suspension edge outer side 321 and the suspension edge inner side 322 of the suspension edge 32 are respectively connected to the frame 10 and the diaphragm element 31, so as to maintain the diaphragm element 31 at the high end opening 102 of the frame 10 by the suspension edge 32. Specifically, first, the frame 10 and the diaphragm element 31 are placed in a suspension molding mold in such a manner that the diaphragm element 31 is held at the high end opening 102 of the frame 10. Next, a suspension molding material such as rubber is injected into the molding mold. Next, the suspension molding material is demolded after solidification to form a suspension 32 between the frame 10 and the diaphragm element 31, whose outer and inner sides are respectively connected to each other. As a result, the outer side 321 and the inner side 322 of the suspension 32 are respectively connected to the frame 10 and the diaphragm element 31, so that the diaphragm element 31 is held at the high end opening 102 of the frame 10 by the suspension 32.

[0092] Preferably, the inner side 322 of the hanging edge 32 covers all outer sides of the diaphragm element 31. Optionally, the inner side 322 of the hanging edge 32 is provided with at least one exposed portion, so that the inner side 322 of the hanging edge 32 covers most of the outer sides of the diaphragm element 31. Optionally, the inner side 322 of the hanging edge 32 covers the periphery of the diaphragm element 31.

[0093] It is worth mentioning that the cross-sectional shape of the suspension edge 32 is not limited in the speaker of the present invention. Figures 2A to 4 In the preferred example of the loudspeaker shown, the cross-sectional shape of the suspension edge 32 is arched, that is, the suspension edge 32 has a suspension edge groove 323, and the opening of the suspension edge groove 323 of the suspension edge 32 faces the magnetic return system 20. Optionally, in other examples of the loudspeaker of the present invention, the cross-sectional shape of the suspension edge 32 may be, but is not limited to, an "S" shape or a wave shape.

[0094] The voice coil 40 has a voice coil high end 41 and a voice coil low end 42 corresponding to the voice coil high end 41, wherein the voice coil high end 41 of the voice coil 40 is connected to the diaphragm element 31, and the voice coil low end 42 of the voice coil 40 extends to the magnetic gap 201 of the magnetic loop system 20 through the magnetic gap opening 202 of the magnetic loop system 20, so that the voice coil 40 is drivably connected to the magnetic loop system 20.

[0095] The linkage part 51 has a linkage high end 511 and a linkage low end 512 corresponding to the linkage high end 511, wherein the linkage high end 511 of the linkage part 51 is connected to the diaphragm element 31 so that the linkage part 51 and the diaphragm element 31 form the linkage mechanism 200, and the linkage low end 512 of the linkage part 51 extends toward the low end opening 103 of the frame 10 in a manner that the linkage part 51 is held in the frame space 101 of the frame 10. The stabilizing shaft part 52 has a stabilizing shaft outer side 521 and a stabilizing shaft inner side 522 corresponding to the stabilizing shaft outer side 521, wherein the stabilizing shaft outer side 521 and the stabilizing shaft inner side 522 of the stabilizing shaft part 52 extend to be connected to the frame 10 and the linkage low end 512 of the linkage part 51, respectively, so that the stabilizing shaft part 52 can connect the linkage mechanism 200 and the frame 10 at one end of the linkage mechanism 200.

[0096] It is worth mentioning that the connection method of the linkage high end 511 of the linkage part 51 and the diaphragm element 31 is not limited in the speaker of the present invention. For example, the linkage high end 511 of the linkage part 51 can be connected to the center position of the diaphragm element 31 by adhesive substances such as glue. Specifically, the diaphragm element 31 has a diaphragm center through-hole 311, wherein after the linkage high end 511 of the linkage part 51 extends from the inner side to the outer side of the diaphragm element 31 through the diaphragm center through-hole 311 of the diaphragm element 31, the linkage high end 511 of the linkage part 51 and the diaphragm element 31 are bonded to the outer side of the diaphragm element 31 by adhesive substances such as glue, thereby connecting the linkage high end 511 of the linkage part 51 to the center position of the diaphragm element 31. More specifically, the diaphragm element 31 has a receiving groove 312, which surrounds the central through-hole 311 of the diaphragm, wherein after the linkage high end 511 of the linkage part 51 extends from the inner side to the outer side of the diaphragm element 31 through the central through-hole 311 of the diaphragm element 31, glue is applied to the receiving groove 312 of the diaphragm element 31, so that the glue or other sticky substances used to connect the linkage high end 511 of the linkage part 51 and the diaphragm element 31 are retained in the receiving groove 312 of the diaphragm element 31.

[0097] It is worth mentioning that the connection mode between the outer side 521 of the stabilizing shaft portion 52 and the frame 10 and the connection mode between the inner side 522 of the stabilizing shaft portion 52 and the linkage lower end 512 of the linkage portion 51 are not limited in the speaker of the present invention.

[0098] For example, in a preferred example of the speaker of the present invention, the stabilizing axis portion 52 is prefabricated, and the stabilizing axis outer side 521 of the stabilizing axis portion 52 is connected to the frame 10 by using adhesive materials such as glue, and the stabilizing axis inner side 522 of the stabilizing axis portion 52 is connected to the linkage lower end 512 of the linkage portion 51 by using adhesive materials such as glue, so that the stabilizing axis outer side 521 and the stabilizing axis inner side 522 of the stabilizing axis portion 52 are respectively connected to the frame 10 and the linkage lower end 512 of the linkage portion 51.

[0099] For example, in the attached Figures 2A to 4 In this preferred example of the speaker shown, the stabilizing axis portion 52 is integrally formed between the frame 10 and the linkage lower end 512 of the linkage portion 51, so that the stabilizing axis outer side 521 and the stabilizing axis inner side 522 of the stabilizing axis portion 52 are respectively connected to the frame 10 and the linkage lower end 512 of the linkage portion 51. Specifically, first, the frame 10 and the linkage part 51 are placed in a shaft stabilizing part molding mold in such a way that the linkage lower end 512 of the linkage part 51 is held in the lower end opening 103 of the frame 10, and secondly, a shaft stabilizing part molding material such as rubber is injected into the shaft stabilizing part molding mold, and then, after the shaft stabilizing part molding material is solidified, the mold is demolded to form the shaft stabilizing part 52 whose outer side and inner side are respectively connected to the frame 10 and the linkage lower end 512 of the linkage part 51, so that the shaft stabilizing outer side 521 and the shaft stabilizing inner side 522 of the shaft stabilizing part 52 are respectively connected to the frame 10 and the linkage lower end 512 of the linkage part 51.

[0100] It is worth mentioning that the cross-sectional shape of the axis-stabilizing portion 52 is not limited in the speaker of the present invention. Figures 2A to 4 In the preferred example of the loudspeaker shown, the cross-sectional shape of the axis-stabilizing portion 52 is arched, that is, the axis-stabilizing portion 52 has an axis-stabilizing groove 523, and the opening of the axis-stabilizing groove 523 of the axis-stabilizing portion 52 faces the magnetic return system 20, so that the distance between the axis-stabilizing portion 52 and the magnetic return system 20 can be reduced, and the axis-stabilizing portion 52 can be prevented from touching the magnetic return system 20 after being pulled and deformed by the linkage portion 51. Optionally, in other examples of the loudspeaker of the present invention, the cross-sectional shape of the axis-stabilizing portion 52 can be, but not limited to, an "S" shape or a wave shape.

[0101] Furthermore, the magnetic return system 20 has a magnetic return center through-hole 205, which passes through the opposite sides of the magnetic return system 20, wherein the middle part of the linkage part 51 is maintained in the magnetic return center through-hole 205 of the magnetic return system 20 in a manner that a safety gap is provided between the outer wall of the linkage part 51 and the inner wall of the magnetic return system 20, so that the two ends of the linkage part 51 can respectively protrude from the magnetic return system 20 to be used for connecting the diaphragm element 31 and the stabilizing axis part 52, which is conducive to the miniaturization of the speaker. In other words, the magnetic loop system 20 surrounds the middle part of the linkage part 51, and the linkage high end 511 and the linkage low end 512 of the linkage part 51 respectively protrude from the opposite sides of the magnetic loop system 20, so that the linkage high end 511 can be connected to the diaphragm element 31 on one side of the magnetic loop system 20, and the linkage low end 512 can be connected to the stabilizing axis part 52 on the other side of the magnetic loop system 20. In this way, when the linkage part 51 is driven by the diaphragm element 31 to vibrate back and forth along the axial direction of the speaker, the diaphragm element 31 and the stabilizing axis part 52 can respectively ensure that the linkage part 51 vibrates back and forth in the axial direction of the speaker at the linkage high end 511 and the linkage low end 512 of the linkage part 51, so as to avoid the linkage part 51 from being deflected, thereby avoiding the vibration direction of the diaphragm element 31 from deviating from the axial direction of the speaker.

[0102] When an electrical signal (audio signal) is connected to the loudspeaker, based on the electromagnetic principle, the magnetic loop system 20 can drive the voice coil 40 to reciprocate along the axial direction of the loudspeaker in a manner that allows the voice coil lower end 42 of the voice coil 40 to move within the magnetic gap 201 of the magnetic loop system 20. At this time, since the voice coil high end 41 of the voice coil 40 is connected to the inner side of the diaphragm element 31, the voice coil 40 can drive (push up and pull down) the diaphragm element 31 to reciprocate along the axial direction of the loudspeaker, thereby generating sound waves by agitating the air through the diaphragm element 31, wherein the suspension edge 32 surrounding the diaphragm element 31 and held between the diaphragm element 31 and the frame 10 can not only be used to limit the stroke of the diaphragm element 31, but also can prevent the movement direction of the diaphragm element 31 from being deflected. The diaphragm element 31 and the linkage part 51 form the linkage mechanism 200, so that when the diaphragm element 31 is driven to reciprocate along the axial direction of the speaker, the diaphragm element 31 can drive the linkage part 51 to synchronously reciprocate along the axial direction of the speaker, and the diaphragm element 31 can prevent the movement direction of the linkage part 51 from being deviated at the linkage high end 511 of the linkage part 51, and accordingly, the stabilizing axis part 52 surrounding the linkage low end 512 of the linkage part 51 and maintained between the linkage low end 512 of the linkage part 51 and the frame 10 can prevent the movement direction of the linkage part 51 from being deviated at the linkage low end 512 of the linkage part 51, so that the movement direction of the linkage part 51 can be reliably maintained in the axial direction of the speaker.

[0103] It can be understood that, in the speaker of the present invention, the suspension edge 32 and the axis stabilizing unit 50 are used to maintain the diaphragm element 31 moving in the axial direction of the speaker, which can effectively prevent the voice coil 40 from being deflected when driven by the magnetic return system 20 and touching the inner wall 203 or the outer wall 204 of the magnetic return system 20, thereby avoiding the occurrence of noise and extending the service life of the speaker.

[0104] Unlike existing speakers that need to ensure the movement direction of the vibration plate by ensuring the movement direction of the voice coil through elastic waves, in the speaker of the present invention, the movement direction of the voice coil 40 is ensured by ensuring the movement direction of the drum paper unit 30, which is conducive to reducing the power of the speaker and increasing the stroke of the drum paper unit 30, so that the miniaturized and low-power speaker can produce lower low frequencies. For example, the speaker of the present invention can produce frequencies as low as 35Hz. In other words, compared with existing speakers, the speaker of the present invention can remove elastic waves and ensure the movement direction of the voice coil 40 by ensuring the movement direction of the drum paper unit 30. This can not only avoid the deflection of the voice coil 40 when it is driven, but also reduce the reaction force on the voice coil 40, thereby reducing the power of the speaker.

Preferably, the shape of the lower frame through-hole 131 of the lower frame 13 is consistent with the shape of the linkage lower end 512 of the linkage portion 52, for example, the shape of the linkage lower end 512 of the linkage portion 51 is circular, and accordingly, the shape of the lower frame through-hole 131 of the lower frame 13 is circular.

[0111] The lower frame 13 is installed at the free end of each of the connecting bodies 113 of the connecting body 11, so as to set the lower frame 13 at the end of the connecting body 11. It is worth mentioning that the installation method of the lower frame 13 and the free end of each of the connecting bodies 113 of the connecting body 11 is not limited in the speaker of the present invention. For example, the outer wall of the lower frame 13 can be squeezed by each of the connecting bodies 113 respectively so that the lower frame 13 is stuck between each of the connecting bodies 113, and glue can be provided between the outer wall of the lower frame 13 and each of the connecting bodies 113 for gluing the lower frame 13 and each of the connecting bodies 113.

[0131] Attached FIG. 12A to FIG. 12C A modified example of the speaker of the present invention is shown. Figure 2A to Figure 4 The speaker shown is different in that the FIG. 12A to FIG. 12C In this specific example of the speaker shown, the cross-sectional shape of the stabilizing axis portion 52 is wavy, wherein the stabilizing axis outer side 521 of the stabilizing axis portion 52 extends outward to be connected to the frame 10, and the stabilizing axis inner side 522 of the stabilizing axis portion 52 extends inward to be connected to the linkage lower end 512 of the linkage portion 51.

[0132] Preferably, in the attached FIG. 12A to FIG. 12C In this specific example of the speaker shown, the wavy stabilizing shaft portion 52 is integrally formed between the frame 10 and the linkage lower end 512 of the linkage portion 51, so that the stabilizing shaft outer side 521 of the stabilizing shaft portion 52 is integrally combined with the frame 10, and the stabilizing shaft inner side 522 of the stabilizing shaft portion 52 is integrally combined with the linkage lower end 512 of the linkage portion 51.

[0133] Attached Fig.13 Another variation of the speaker according to the present invention is shown. Fig. 12A The difference from the speaker shown in FIG. 12C is that Fig.13In the specific example of the loudspeaker shown, the cross-sectional shape of the shaft-stabilizing portion 52 is "S"-shaped.

[0134] Attached FIG. 14A to FIG. 14C Another modified example of the speaker of the present invention is shown, as shown in FIG. Figure 4 The speaker shown is different in that the FIG. 14A to FIG. 14C In this specific example of the speaker shown, the stabilizing axis portion 52 includes an external frame 524, an internal frame 525 and at least two stabilizing axis bodies 526 extending between the external frame 524 and the internal frame 525, wherein the external frame 524 of the stabilizing axis portion 52 forms the stabilizing axis outer side 521 of the stabilizing axis portion 52, and the external frame 524 of the stabilizing axis portion 52 is connected to the frame 10, and accordingly, the internal frame 525 of the stabilizing axis portion 52 forms the stabilizing axis inner side 522 of the stabilizing axis portion 52, and the internal frame 525 of the stabilizing axis portion 52 is connected to the linkage lower end 512 of the linkage portion 51.

[0135] When an electrical signal (audio signal) is connected to the loudspeaker, based on the electromagnetic principle, the magnetic loop system 20 can drive the voice coil 40 to reciprocate along the axial direction of the loudspeaker in a manner that allows the voice coil lower end 42 of the voice coil 40 to move within the magnetic gap 201 of the magnetic loop system 20. At this time, since the voice coil high end 41 of the voice coil 40 is connected to the inner side of the diaphragm element 31, the voice coil 40 can drive (push up and pull down) the diaphragm element 31 to reciprocate along the axial direction of the loudspeaker, thereby generating sound waves by agitating the air through the diaphragm element 31, wherein the suspension edge 32 surrounding the diaphragm element 31 and held between the diaphragm element 31 and the frame 10 can not only be used to limit the stroke of the diaphragm element 31, but also can prevent the movement direction of the diaphragm element 31 from being deflected. The diaphragm element 31 and the linkage part 51 form the linkage mechanism 200, so that when the diaphragm element 31 is driven to reciprocate along the axial direction of the speaker, the diaphragm element 31 can drive the linkage part 51 to synchronously reciprocate along the axial direction of the speaker, and the diaphragm element 31 can prevent the movement direction of the linkage part 51 from being deflected at the linkage high end 511 of the linkage part 51, and accordingly, the stabilizing axis part 52 surrounding the linkage low end 512 of the linkage part 51 and maintained between the linkage low end 512 of the linkage part 51 and the frame 10 can prevent the movement direction of the linkage part 51 from being deflected at the linkage low end 512 of the linkage part 51, so that the movement direction of the linkage part 51 can be reliably maintained in the axial direction of the speaker. The stabilizing axis part 52 is made of an elastic material, so that the stabilizing axis part 526 of the stabilizing axis part 52 can be deformed with the movement of the diaphragm element 31.

[0136] It is worth mentioning that the material forming the axis stabilizing portion 52 is not limited in the speaker of the present invention, as long as the axis stabilizing portion 52 has elasticity. For example, the axis stabilizing portion 52 can be made of rubber material or metal material.
