It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.
[0024] The following is the content of the first aspect of the utility model:
[0025] Please refer to Figure 1 In the embodiment, the loudspeaker with built-in pressure equalizing channel comprises a diaphragm 1, a voice coil 2, a support 3, a first magnetic assembly 4, a second magnetic assembly 5 and a cover member 6.
[0026] The diaphragm 1 and the cover member 6 are arranged at two ends of the support 3 to form a containing cavity; the first magnetic assembly 4 and the second magnetic assembly 5 are arranged in the containing cavity, and the second magnetic assembly 5 is located in the first magnetic assembly 4 to form a gap; one end of the voice coil 2 is connected to the diaphragm 1, and the other end of the voice coil 2 is located in the gap.
[0027] Specifically, the diaphragm 1 is provided with a first pressure equalizing hole 11, the second magnetic assembly 5 is provided with a second pressure equalizing hole 53, and the cover member 6 is provided with a third pressure equalizing hole 61; the first pressure equalizing hole 11, the second pressure equalizing hole 53 and the third pressure equalizing hole 61 are sequentially communicated to form a pressure equalizing channel.
[0028] The first equalizing hole 11, the second equalizing hole 53 and the third equalizing hole 61 can have the same or different sizes, and can be aligned or offset.
[0029] In a preferred embodiment, the first equalizing hole 11 is arranged in the middle of the diaphragm 1, the second equalizing hole 53 is arranged in the middle of the second magnetic assembly 5, and the third equalizing hole 61 is arranged in the middle of the cover 6. The first equalizing hole 11, the second equalizing hole 53 and the third equalizing hole 61 have the same size. It is easy to understand that arranging the second equalizing hole 53 in the middle of the second magnetic assembly 5 can effectively reduce the influence of the second equalizing hole 53 on the magnetism of the second magnetic assembly 5.
[0030] After the speaker starts to operate, the voice coil 2 located in the gap formed by the first magnetic assembly 4 and the second magnetic assembly 5 generates a magnetic field after current passes through the voice coil 2. Under the interaction of the magnetic fields of the first magnetic assembly 4 and the second magnetic assembly 5, the voice coil 2 moves under the action of electromagnetic force, and then pushes the diaphragm 1 to vibrate to generate sound waves. In the process of vibration of the diaphragm 1, the pressure balance channel is used to balance the pressure between the front cavity of the earphone and the outside.
[0031] It can be understood that by arranging the first equalizing hole 11, the second equalizing hole 53 and the third equalizing hole 61 on the diaphragm 1, the second magnetic assembly 5 and the cover 6 respectively, and using the first equalizing hole 11, the second equalizing hole 53 and the third equalizing hole 61 to form the pressure balance channel in sequence, the pressure balance part of the speaker can be arranged inside the speaker. Without affecting the overall magnetic performance of the second magnetic assembly 5, the volume of the speaker can be reduced, the overall shape of the speaker is relatively more regular, the space occupation of the speaker in the earphone can be effectively reduced, and the space stacking in the earphone can be facilitated.
[0032] Further, please refer to Figure 2 In an embodiment, the support 3 includes a hollow accommodating body 31 and an electrical connection part 32 arranged on one side of the accommodating body 31. One end of the accommodating body 31 protrudes with a mounting boss 311, and the accommodating body 31 forms an abutting platform 312.
[0033] The accommodating body 31 is used to accommodate the first magnetic assembly 4 and the second magnetic assembly 5; the electrical connection part 32 is used to mount the electrode of the speaker; the mounting boss 311 is used to mount the diaphragm 1; and the abutting platform 312 is used to support the first magnetic assembly 4.
[0034] Specifically, the first magnetic component 4 is arranged in the accommodating body 31 and is bonded to the abutting platform 312; the second magnetic component 5 is bonded to the cover 6; and the diaphragm 1 is bonded to the mounting boss 311. It can be easily understood that, by arranging the mounting boss 311 and the abutting platform 312, the mounting efficiency and convenience of the diaphragm 1 and the first magnetic component 4 can be improved.
[0035] Further, please refer to Figure 2 In a preferred embodiment, the electric connection part 32 is provided with a communication groove 321 that communicates with the accommodating body 31. Specifically, the side wall of the communication groove 321 provided on the electric connection part 32 can be a plane or a curved surface, and preferably is a plane. It can be easily understood that, by selecting the side wall as a plane, the processing difficulty can be reduced, thereby reducing the production cost.
[0036] It can be understood that, by arranging the communication groove 321 that communicates with the accommodating body 31, the convenience of disassembling the cover 6 can be improved, thereby improving the convenience of later maintenance or replacement of the first magnetic component 4 and the second magnetic component 5 mounted in the accommodating body 31.
[0037] Further, please refer to Figure 2 and Figure 3 In a preferred embodiment, the other end of the accommodating body 31 is formed with a limiting block 313, and the cover 6 is provided with a limiting groove 62 that corresponds to the limiting block 313.
[0038] The limiting block 313 and the limiting groove 62 are used for positioning and limiting the installation of the cover 6 and the bracket 3. Specifically, the number of the limiting block 313 and the limiting groove 62 can be selected according to the actual design requirements. In a preferred embodiment, the number of the limiting block 313 and the limiting groove 62 is 3. It can be easily understood that, by setting the number of the limiting block 313 and the limiting groove 62 to 3, the installation of the cover 6 and the bracket 3 can be more stable by using the principle of three-point surface.
[0039] It can be understood that, by arranging the limiting block 313 and the limiting groove 62 on the accommodating body 31 and the cover 6 respectively, the convenience and efficiency of positioning and installing the cover 6 on the bracket 3 can be improved by the cooperation between the limiting block 313 and the limiting groove 62, and the stability of the installation of the cover 6 and the bracket 3 can be improved to a certain extent.
[0040] Further, please refer to Figure 1 In an embodiment, the first magnetic component 4 includes a first magnetic body 41 and a first magnetic conductor 42 bonded to the first magnetic body 41; and the second magnetic component 5 includes a second magnetic body 51 and a second magnetic conductor 52 bonded to the second magnetic body 51, and a second pressure equalizing hole 53 penetrating through the second magnetic body 51 and the second magnetic conductor 52.
[0041] The first magnetic body 41 is an outer magnetic member of the loudspeaker, the second magnetic body 51 is an inner magnetic member of the loudspeaker, the first magnetic conductor 42 is used for conducting and concentrating the magnetic field of the first magnetic body 41, and the second magnetic conductor 52 is used for conducting and concentrating the magnetic field of the second magnetic body 51, and can also support the diaphragm 1.
[0042] It can be understood that, by the first magnetic conductor 42 and the second magnetic conductor 52, the magnetic fields of the first magnetic body 41 and the second magnetic body 51 can be concentrated into the gap formed by the first magnetic assembly 4 and the second magnetic assembly 5 respectively, and a relatively strong magnetic field can be generated in the gap, which is more conducive to the interaction with the voice coil 2.
[0043] Further, please refer to Figure 4 In a preferred embodiment, the second magnetic assembly 5 further comprises a third magnetic body 54, the third magnetic body 54 is bonded to the second magnetic conductor 52, and the second pressure equalizing hole 53 penetrates the third magnetic body 54.
[0044] It can be understood that, by setting the third magnetic body 54, the second magnetic body 51 and the third magnetic body 54 can form a double-inner-magnetic-member structure, the third magnetic body 54 can support the diaphragm 1 while relatively greatly improving the BL value, thereby improving the sensitivity of the loudspeaker with the built-in pressure equalizing channel.
[0045] Further, please refer to Figure 3 In an embodiment, the cover member 6 is provided with a plurality of tuning holes 63.
[0046] Specifically, the number and aperture of the tuning holes 63 can be selected according to the actual design requirements, and the distribution mode of the tuning holes 63 includes but is not limited to circular distribution and matrix distribution, and the like. Similarly, the distribution mode can be selected and set according to the design requirements.
[0047] In a preferred embodiment, the tuning holes 63 are distributed at an equal angle around the third pressure equalizing hole 61. It can be understood that, by adopting the equal angle distribution mode around the third pressure equalizing hole 61, the overall distribution of the tuning holes 63 can be relatively more uniform, thereby enabling the loudspeaker to obtain a relatively better tuning effect, and thereby improving the playing effect of the loudspeaker.
[0048] Further, please refer to Figure 4 In an embodiment, the loudspeaker with the built-in pressure equalizing channel further comprises a tuning gauze 7, the tuning gauze 7 is bonded to the cover member 6.
[0049] It can be understood that the tuning mesh cloth 7 is bonded to the cover 6, which can realize covering the tuning hole 63 and the third equalizing hole 61 at the same time, thereby realizing the double effect of the single tuning mesh cloth 7 playing the tuning and covering the third equalizing hole 61, which can reduce the bonding steps in the production process, and further reduce the production cost of the built-in equalizing channel loudspeaker.
[0050] In summary, the utility model discloses a first equalizing hole 11, second equalizing hole 53 and third equalizing hole 61 are set up on the diaphragm 1, second magnetic assembly 5 and cover 6 respectively, and the equalizing channel is formed by the first equalizing hole 11, second equalizing hole 53 and third equalizing hole 61 in turn, and the equalizing part of the loudspeaker is arranged in the inside of the loudspeaker, so that the volume of the loudspeaker can be reduced under the premise of not affecting the overall magnetic performance of the second magnetic assembly 5, the overall shape of the loudspeaker is relatively more regular, the space occupation of the loudspeaker in the earphone can be effectively reduced, and the space stacking in the earphone is facilitated.
