It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The following is the content of the first aspect of the present invention:

[0027] Please refer to Figures 1 to 3 In this embodiment, the dual dynamic loudspeaker includes a first magnetic component 1, a first sound-emitting component 2, a first bracket 3, a second magnetic component 4, a second sound-emitting component 5, a second bracket 6 and a partition 7.

[0028] The first magnetic component 1 is used to generate a first magnetic field in the speaker to interact with the first sound-emitting component 2, thereby pushing the first sound-emitting component 2 and generating corresponding sound waves. The second magnetic component 4 is used to generate a second magnetic field in the speaker to interact with the second sound-emitting component 5, thereby pushing the second sound-emitting component 5 and generating corresponding sound waves.

[0029] The first bracket 3 is used to accommodate the first magnetic component 1 and install the first sound component 2, and the second bracket 6 is used to accommodate the second magnetic component 4 and install the second sound component 5. The first sound component 2 is a bass sound unit of the speaker, and the second sound component 5 is a treble sound unit of the speaker.

[0030] The first magnetic component 1 and the first sound component 2 constitute a bass module of the speaker, and the second magnetic component 4 and the second sound component 5 constitute a treble module of the speaker. Preferably, the bass module and the treble module of the speaker are coaxially arranged in the speaker, that is, the first magnetic component 1, the first sound component 2, the second magnetic component 4 and the second sound component 5 are coaxially arranged in the speaker.

[0031] The partition 7 is used to form two independent chambers in the speaker to separate the bass module and the tweeter module, that is, the partition 7 separates the first magnetic component 1 and the first sound component 2 in the same chamber, and separates the second magnetic component 4 and the second sound component 5 in another chamber.

[0032] A first cavity connecting the two ends of the first bracket 3 is formed inside the first bracket 3, the first magnetic component 1 is arranged inside the first bracket 3, and the first sound component 2 is covered on one end of the first bracket 3; a first through hole 211 is opened on the first sound component 2; the partition 7 is embedded in the first bracket 3 and covers the other end of the first bracket 3, the partition 7 passes through the first through hole 211, and the interior of the partition 7 is provided with a accommodating cavity 71 connecting the two ends of the partition 7, a second cavity is provided inside the second bracket 6, the second magnetic component 4 is arranged inside the second bracket 6, and the second sound component 5 is installed on one end of the second bracket 6; the second bracket 6 is embedded in the accommodating cavity 71, and the second magnetic component 4 and the second sound component 5 are both located in the accommodating cavity 71.

[0033] Specifically, the first magnetic component 1 includes a hollow first magnetic body 11 and a hollow first magnetic conductive body 12 arranged on the first magnetic body 11, and the partition 7 passes through the first magnetic body 11 and the first magnetic conductive body 12; the first sound-generating component 2 includes a first diaphragm 21 and a first voice coil 22 with a first through hole 211. The first magnetic body 11 and the first magnetic conductive body 12 are both arranged in the first cavity of the first bracket 3, and a first gap is formed between the first magnetic body 11, the first magnetic conductive body 12 and the partition 7 embedded in the first bracket 3. The first diaphragm 21 is installed at one end of the first bracket 3. One end of the first voice coil 22 is connected to the first diaphragm 21, and the other end of the first voice coil 22 is located in the first gap.

[0034] It can be understood that the first magnetic component 1 generates a first magnetic field in the speaker. During the operation of the speaker, a changing current passes through the first voice coil 22, and the first voice coil 22 located in the first gap generates a magnetic field with a corresponding changing intensity. Under the interaction of the magnetic field, the first voice coil 22 reciprocates in the first gap, thereby driving the first diaphragm 21 to vibrate reciprocatingly to generate corresponding sound waves.

[0035] The second magnetic component 4 includes a second magnetic body 41 and a second magnetic conductor 42 disposed on the second magnetic body 41; the second sound-generating component 5 includes a second diaphragm 51 and a second voice coil 52. The second magnetic body 41 and the second magnetic conductor 42 are both disposed in the second bracket 6, and a second gap is formed between the second magnetic body 41, the second magnetic conductor 42 and the side wall of the second cavity. The second diaphragm 51 is mounted on one end of the second bracket 6, one end of the second voice coil 52 is connected to the second diaphragm 51, and the other end of the second voice coil 52 is located in the second gap. One end of the second diaphragm 51 mounted on the second bracket 6 is embedded in the accommodating cavity 71 of the partition 7.

[0036] It can be understood that the second magnetic component 4 generates a second magnetic field in the speaker. During the operation of the speaker, the changing current passes through the second voice coil 52, and the second voice coil 52 located in the second gap generates a magnetic field with a corresponding change in strength. Under the interaction of the magnetic field, the second voice coil 52 reciprocates in the second gap, thereby driving the second diaphragm to reciprocate to generate corresponding sound waves. The partition 7 passes through the first through hole 211 on the first diaphragm 21, and the accommodating cavity 71 connects the two ends of the partition 7. The sound waves generated by the second sound-generating component 5 can be output to the outside through the accommodating cavity 71.

[0037] The dual dynamic loudspeaker provided in the present application is provided with a partition 7 which penetrates the first through hole 211 inside the loudspeaker and forms a accommodating cavity 71 inside, and the tweeter module of the loudspeaker is arranged in the accommodating cavity 71 of the partition 7, thereby realizing the separate arrangement and independent output of the bass module and the tweeter module, which can effectively reduce the phase interference between the first sound component 2 and the second sound component 5, increase the bandwidth of the loudspeaker, improve the acoustic performance of the loudspeaker, and at the same time, can effectively reduce the structural height of the loudspeaker, reduce the volume of the loudspeaker, thereby improving the spatial layout freedom of the loudspeaker in the earphone, and improving the diversity of the earphone design to a certain extent.

[0038] For further information, please refer to Figures 3 to 5 In one embodiment, the partition 7 includes a supporting body 72, a covering body 73 and a sound guide body 74; the covering body 73 is formed by extending from one end of the supporting body 72; the sound guide body 74 is formed by extending from the other end of the supporting body 72, and the sound guide body 74 passes through the first through hole 211.

[0039] Among them, the bearing body 72 is the main structure of the partition 7 for accommodating the device. The overall shape of the bearing body 72 includes but is not limited to a column or an irregular column, which can be selected according to the actual design requirements. Preferably, the overall shape of the bearing body 72 is a column. The cover body 73 is an auxiliary structure for fixing the partition 7 to the first bracket 3, and is also used to assist in separating the bass module and the tweeter module. The sound guide body 74 is the sound output structure of the partition 7 for assisting the tweeter module in outputting sound waves, which can conduct the sound waves generated by the second sound-generating component 5 to the outside of the speaker.

[0040] Specifically, the accommodating cavity 71 passes through the carrying body 72 and the sound guiding body 74, and the accommodating cavity 71 includes a carrying cavity 711 arranged in the carrying body 72 and a sound guiding cavity 712 arranged in the sound guiding body 74, the carrying cavity 711 is used to accommodate the second magnetic component 4, the second sound emitting component 5 and the second bracket 6, and the sound guiding cavity 712 is used to conduct the sound waves generated by the second sound emitting component 5.

[0041] After the first magnetic component 1 and the first sound-emitting component 2 are arranged in the first bracket 3, the partition 7 is embedded in the first bracket 3, and the sound guide 74 passes through the first through hole 211 on the first diaphragm 21. The structural height of the sound guide 74 passing through the first through hole 211 needs to be designed in combination with the vibration range of the first diaphragm 21, the output effect of the tweeter module and the spatial structure of the speaker. Preferably, the structure of the sound guide 74 passing through the first through hole 211 is higher than the first diaphragm 21.

[0042] After the second magnetic component 4 and the second sound component 5 are installed in the second bracket 6, the second bracket 6 is embedded in the bearing cavity 711 of the bearing body 72. After the second sound component 5 generates sound waves, the sound waves are conducted to the outside of the speaker through the sound guide cavity 712 of the sound guide body 74.

[0043] It is understandable that by providing a bearing cavity 711 on the bearing body 72 of the partition 7, the second magnetic component 4 and the second sound component 5 can be accommodated, which can effectively reduce the space occupied by the second magnetic component 4 and the second sound component 5 in the speaker, improve the compactness of the internal structure of the speaker, avoid the overall height of the speaker being too large, and further optimize the spatial layout of the speaker in the earphone. By providing a sound guide cavity 712 connected to the bearing cavity 711 of the bearing body 72 on the partition 7, the sound waves generated by the second sound component 5 can be output to the outside of the speaker while separating the first sound component 2 from the second sound component 5, which can effectively reduce the phase interference between the first sound component 2 and the second sound component 5, increase the bandwidth of the speaker, and improve the acoustic performance of the speaker.

[0044] For further information, please refer to Figure 4In one embodiment, at least one tuning hole 731 is provided on the cover body 73. The tuning hole 731 is used to adjust the sound effect output by the speaker.

[0045] Specifically, the shape and number of the tuning holes 731 can be selected according to actual design requirements. In a preferred embodiment, the tuning holes 731 are two arc-shaped through grooves, and the two arc-shaped grooves are symmetrically arranged on the cover body 73.

[0046] It can be understood that the use of two symmetrically arranged arc-shaped tuning holes is more conducive to the flow of air, which can better disperse the internal air pressure, enhance the low frequency of the speaker, increase the depth and fullness of the sound, thereby improving the acoustic performance of the speaker, and is more conducive to the heat dissipation of the internal components of the speaker.

[0047] Furthermore, in order to improve the installation efficiency of the partition 7 embedded in the first bracket 3, please refer to Figure 5 In a preferred embodiment, a first positioning portion 732 is provided on the cover body 73 , and a second positioning portion 35 matching with the first positioning portion 732 is provided on the first bracket 3 .

[0048] The first positioning portion 732 and the second positioning portion 35 are used to assist the positioning and installation between the cover assembly 73 and the first bracket 3. The first positioning portion 732 and the second positioning portion 35 correspond to each other one by one. The first positioning portion 732 can be any one of the positioning block and the positioning groove, and the second positioning portion 35 can be the remaining one of the positioning block and the positioning groove. The design can be selected according to the actual situation.

[0049] Specifically, the number of the first positioning portion 732 and the second positioning portion 35 can be selected according to the actual design requirements. Preferably, the number of the first positioning portion 732 and the second positioning portion 35 are both three. It can be understood that by using the principle of three points forming a plane, the number of the first positioning portion 732 and the second positioning portion 35 is set to three, so that the three groups of the first positioning portion 732 and the second positioning portion 35 can form a plane, which can improve the convenience of positioning and installation between the cover body 73 and the first bracket 3, and can also better constrain the degree of freedom between the cover body 73 and the first bracket 3.

[0050] For further information, please refer to Figure 6 In one embodiment, the first bracket 3 includes a first main body portion 31 , an electrical connection portion 32 and a voltage equalizing portion 33 ; the electrical connection portion 32 and the voltage equalizing portion 33 are both connected to the outer surface of the first main body portion 31 , and the first cavity 311 is formed in the first main body portion 31 .

[0051] The first main body 31 is used to accommodate the first magnetic component 1 and carry the first sound-emitting component 2. The shape of the first main body 31 includes but is not limited to a ring shape, a square shape, etc., which can be selected according to the actual design requirements. Preferably, the first main body 31 is a hollow ring. The electrical connection part 32 is the electrical connection structure of the bass module; the pressure equalization part 33 is used to balance the pressure between the cavity where the speaker is installed and the outside world.

[0052] Specifically, the first main body 31 is formed with a second positioning portion 35 that matches the first positioning portion 732 on the cover body 73, and a support platform for mounting the first magnetic component 1 is formed in the first cavity 311 in the first main body 31. The electrical connection portion 32 is provided with an electrode for electrically connecting the first voice coil 22, and an external control current is input and output into the first voice coil 22 through the electrode, and the first voice coil 22 generates a changing magnetic field as the current output by the electrical connection portion 32 changes.

[0053] The electrical connection part 32 and the voltage equalizing part 33 may be connected to the same side of the outer surface of the first main body part 31, or may be connected to different sides of the outer surface of the first main body part 31. Preferably, the electrical connection part 32 and the voltage equalizing part 33 are connected to the same side of the outer surface of the first main body part 31. It is easy to understand that connecting the electrical connection part 32 and the voltage equalizing part 33 to the same side of the outer surface of the first main body part 31 is more conducive to improving the freedom of the spatial layout of the speaker.

[0054] Furthermore, the shape and number of the voltage equalizing part 33 will affect the overall acoustic performance of the speaker. In a preferred embodiment, the voltage equalizing part 33 is two arc-shaped parts, which are symmetrically arranged on both sides of the electrical connection part 32 and smoothly connected between the electrical connection part 32 and the first main body part 31.

[0055] It can be understood that by providing two arc-shaped pressure-equalizing portions 33, it is more conducive to the flow of air in the earphone cavity where the speaker is installed, and is more conducive to balancing the internal and external air pressure, which can effectively improve the output frequency response of the speaker, enhance the low-frequency performance, reduce sound distortion, and improve the sound quality of the speaker output. At the same time, it can reduce the feeling of oppression when wearing the earphones to a certain extent and improve the wearing comfort.

[0056] Furthermore, in a preferred embodiment, at least one third positioning portion 34 is provided on the outer surface of the first main body portion 31. The third positioning portion 34 is used to assist the positioning and installation of the speaker in the earphone cavity.

[0057] Specifically, the third positioning portion 34 can be any one of a positioning block or a positioning groove, which can be selected according to the actual design requirements. Preferably, the third positioning portion 34 is a positioning block. Similarly, the number of the third positioning portions 34 can be selected according to the actual design requirements. Preferably, the number of the third positioning portions 34 is two, and the two third positioning portions 34 are respectively and relatively arranged on both sides of the outer surface of the first main body portion 31. It is easy to understand that the provision of two third positioning portions 34 can better balance the force of the speaker and better constrain the freedom of the speaker in the earphone cavity.

[0058] It can be understood that by providing the third positioning portion 34 on the outer surface of the first main body portion 31 , the speaker can be quickly positioned and installed in the earphone cavity, thereby improving the convenience and efficiency of speaker installation.

[0059] For further information, please refer to Figure 2 In one embodiment, a FPC component 8 is disposed on a surface of the partition 7 away from the first sound-emitting component 2. The FPC component 8 is an electrical connection device for controlling the tweeter module.

[0060] Specifically, the FPC component 8 is arc-shaped and bonded to the side of the cover body 73 of the partition 7 away from the first sound-emitting component 2. The FPC component 8 is provided with a connector for connecting the second voice coil 52, that is, the FPC component 8 is provided with a pad or electrode for electrically connecting the second voice coil 52.

[0061] The current of the externally controlled tweeter module is input to the second voice coil 52 through the pads or electrodes on the FPC component 8. The second voice coil 52 generates a corresponding changing magnetic field according to the changing current. The second voice coil 52 generates corresponding movement under the action of the second magnetic component 4.

[0062] In a preferred embodiment, please refer to Figure 2 , a wire outlet hole 61 is provided on the second bracket 6. The wire outlet hole 61 penetrates the second cavity of the second bracket 6, and the wire outlet hole 61 is a wiring channel for the second voice coil 52 to be electrically connected to the FPC component 8. It can be understood that by providing the wire outlet hole 61 on the second bracket 6, the electrical connection wiring design of the second sound-emitting component 5 can be optimized, thereby optimizing the spatial layout inside the speaker.

[0063] It can be understood that by setting the FPC component 8, the physical frequency division of the bass module and the tweeter module can be achieved, the control structure of the bass module and the tweeter module can be optimized, and the compactness of the overall structure of the speaker can be improved. The wiring design of the tweeter module can be optimized through the wire outlet hole 61, and the process steps of the speaker electrical connection are optimized, which improves the installation efficiency of the speaker and can reduce the production cost of the speaker to a certain extent.

[0064] For further information, please refer to Figure 3In one embodiment, a copper ring 9 is provided between the second bracket 6 and the accommodating cavity 71. Specifically, the copper ring 9 abuts between the second bracket 6 and the accommodating cavity 71 to achieve auxiliary pressing and fixing of the second diaphragm 51.

[0065] It can be understood that by arranging the copper ring 9 between the second bracket 6 and the accommodating cavity 71, the copper ring 9 abuts against the second bracket 6 and the accommodating cavity 71, which can improve the installation stability of the second diaphragm 51. At the same time, it can help improve the sound characteristics of the second sound-emitting component 5 to a certain extent, so as to improve the acoustic performance of the speaker.

[0066] To summarize, the dual dynamic loudspeaker provided in the present application is provided with a partition 7 which penetrates the first through hole 211 inside the loudspeaker and forms a accommodating cavity 71 inside, and the tweeter module of the loudspeaker is arranged in the accommodating cavity 71 of the partition 7, thereby realizing the separate arrangement and independent output of the bass module and the tweeter module, which can effectively reduce the phase interference between the first sound component 2 and the second sound component 5, increase the bandwidth of the loudspeaker, improve the acoustic performance of the loudspeaker, and at the same time, effectively reduce the structural height of the loudspeaker, reduce the volume of the loudspeaker, thereby improving the spatial layout freedom of the loudspeaker in the earphone, and to a certain extent improving the diversity of the earphone design.

[0067] The second aspect of the present invention also provides an earphone, which includes the dual dynamic speakers in the aforementioned embodiment. The dual dynamic speakers can improve the spatial stacking freedom inside the earphone and improve the sound quality of the earphone output.

[0068] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
