Detailed Description
In the present embodiments, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.
With the development of technology, the popularity of electronic devices such as mobile phones, computers, and sound boxes is increasing, and people's lives are closely related. The speaker (commonly called "loudspeaker") is an important component of the electronic device, and the performance of the speaker directly affects the experience of the user when using the electronic device. Therefore, how to design the structure of a speaker to improve the performance of the speaker has become an important subject in the industry.
As shown in fig. 1, fig. 1 is a schematic diagram of a partial structure of a speaker in the related art. The loudspeaker comprises a basin frame 01, a vibrating diaphragm 02 and a folding ring 03. Wherein the frame 01 has an opening 011, a connection flange 012 is formed at an edge of the opening 011, and the connection flange 012 extends toward a side toward which the opening 011 faces (i.e., an upper side shown in fig. 1). The folding ring 03 comprises an arch portion 031, a vibrating diaphragm connecting portion 032 connected with the inner edge of the arch portion 031, and a frame connecting portion 033 connected with the outer edge of the arch portion 031, wherein the vibrating diaphragm connecting portion 032 is connected with the vibrating diaphragm 02, the frame connecting portion 033 extends along the radial direction of the folding ring 03, and the frame connecting portion 033 is connected with the top surface 0121 of the connecting flange 012, so that the frame connecting portion 033 and the frame 01 are relatively fixed.
As shown in fig. 1, since the frame connecting portion 033 is connected to the top surface 0121 of the connecting flange 012, when the ring 03 is mounted, it is necessary to align the frame connecting portion 033 with the top surface 0121 of the connecting flange 012, and in the alignment process, the frame connecting portion 033 is easily dislocated from the top surface 0121 of the connecting flange 012, so that the mounting position of the ring 03 is easily deviated from the preset position, and thus the ring 03 and the diaphragm 02 are easily unbalanced in stress during vibration, thereby adversely affecting the sound emission performance of the speaker.
As shown in fig. 2, fig. 2 is a schematic partial structure of another speaker in the related art, which is different from the speaker shown in fig. 1 in that, in the speaker shown in fig. 2, a frame connecting portion 033 extends along an axial direction of a hinge 03, and the frame connecting portion 033 is connected to an outer side surface 0122 of a connecting flange 012, so that the frame connecting portion 033 is relatively fixed to a frame 01.
When the folding ring 03 is installed, the frame connecting part 033 needs to be "standing" on the outer side of the connecting flange 012, and because the material of the frame connecting part 033 is soft (in order to ensure the vibration performance of the folding ring 03), the frame connecting part 033 is easy to deform when standing, so that the outer side surface 0122 of the frame connecting part 033 relative to the connecting flange 012 is easy to be misplaced, the installation position of the folding ring 03 is easy to deviate from the preset position, and thus the folding ring 03 and the vibrating diaphragm 02 are easy to be stressed unbalanced during vibration, thereby affecting the sounding performance of the loudspeaker to a certain extent.
In summary, in the speaker of the related art, the position deviation easily occurs when the folded ring 03 is installed, and the folded ring 03 and the diaphragm 02 easily have unbalanced stress when vibrating, so as to adversely affect the sound emission performance of the speaker.
Therefore, the embodiment of the application provides a loudspeaker and electronic equipment, through setting up the basin frame connecting portion that has the location space on the ring, when installing the ring, this location space can be with basin frame connecting portion location on the flange of the opening edge of basin frame to the ring that turns over of the loudspeaker among the correlation technique appears the problem of positional deviation easily when installing.

By such design, the connection of the frame connection part 33 with the surfaces of the flange 12 on a plurality of different sides (namely the top surface 121 and the side surface 121 of the flange 12) can be realized, so that the connection area of the frame connection part 33 with the flange 12 is increased, the connection strength between the frame connection part 33 and the flange 12 is improved, and the probability of detachment of the frame connection part 33 from the flange 12 can be reduced. And, the first connecting wall 331 and the second connecting wall 332 are respectively connected with the top surface 121 and the side surface 122 of the flange 12, and the flange 12 plays a role of limiting and stopping the first connecting wall 331 and the second connecting wall 332 respectively, so that the movement of the folded ring 3 in multiple directions (for example, two directions of horizontal right and vertical down in fig. 6) can be limited, the dislocation of the folded ring 3 in the multiple directions is avoided, and therefore the normal vibration of the folded ring 3 and the vibrating diaphragm 4 is ensured, and the sounding performance of the loudspeaker is further ensured.
The first connecting wall 331 and the top surface 121 of the flange 12 may be connected by an adhesive, a snap connection, a fastener connection, or the like, which is not specifically limited herein. The second connecting wall 332 and the side 122 of the flange 12 may be connected by an adhesive, a snap connection, a fastener connection, etc., and is not particularly limited herein.
It should be noted that: along the extending direction of the flange 12, the end surface of the flange 12 away from the root is a top surface 121 of the flange 12, the surface of the flange 12 connected between the root of the flange 12 and the edge of the top surface 121 is a side surface 122 of the flange 12, and the joint between the flange 12 and the edge of the opening 11 is the root of the flange 12. For example, as shown in fig. 6, the flange 12 extends in the axial direction Z (vertical direction in fig. 6) of the fold ring 3, and then the upper end surface of the flange 12 is a top surface 121 of the flange 12, and the surface between the edge connected to the upper end surface of the flange 12 and the lower end of the flange 12 is a side surface 122 of the flange 12.
In some embodiments, as shown in fig. 5 and 6, the first connecting wall 331 is connected to the outer edge of the arch 31, the first connecting wall 331 extends away from the central axis 30 of the ring 3, the second connecting wall 332 is located on a side of the flange 12 away from the central axis 30 of the ring 3, and the second connecting wall 332 is connected to the first connecting wall 331.
Through setting up first connecting wall 331 to the direction extension of the axis 30 of keeping away from the ring 3, can avoid first connecting wall 331 to stretch into the space 35 that arch 31 encloses like this, when ring 3 along with vibrating diaphragm 4 along the axial X vibration of basin frame 1, just can avoid first connecting wall 331 to produce structural interference with arch 31 to guarantee the normal vibration of ring 3 and vibrating diaphragm 4. By disposing the second connecting wall 332 on the side of the flange 12 away from the central axis 30 of the gimbal 3, the flange 12 can limit the movement of the second connecting wall 332 in the direction approaching the central axis 30 of the gimbal 3, so as to avoid dislocation of the gimbal 3 during vibration.
In some embodiments, as shown in fig. 5 and 6, in the first cross section, the first connecting wall 331 and the second connecting wall 332 are L-shaped as a whole, that is: the angle between the first connecting wall 331 and the second connecting wall 332 is a right angle or an approximately right angle (within 10 degrees from the right angle). The first section is a section passing through each point on the central axis 30 of the folded ring 3 and intersecting both the first connecting wall 331 and the second connecting wall 332, such as the section A-A shown in fig. 4 and 5.
By such design, the first connecting wall 331 and the second connecting wall 332 form an included angle space with an approximate right angle, so that the basin frame connecting portion 33 can be better matched with the flange 12, and can be more stably positioned on the flange 12. The first connecting wall 331 and the second connecting wall 332 are L-shaped, so that the connecting area between the first connecting wall 331, the second connecting wall 332 and the flange 12 can be increased, which is beneficial to improving the connection strength and connection reliability between the basin frame connecting portion 33 and the flange 12.
Of course, in addition to the above-described structure, in the first cross section, the first connecting wall 331 and the second connecting wall 332 may be designed to be S-shaped, and in this case, the first connecting wall 331 and the second connecting wall 332 are in line contact with the flange 12.
As shown in fig. 7a, 7b and 8, fig. 7a is a schematic perspective view of a speaker in a second embodiment of the present application, fig. 7b is a longitudinal sectional view of the speaker shown in fig. 7a, and fig. 8 is a partially enlarged view of the speaker at C in fig. 7 b. The main difference between the speaker in the second embodiment of the present application and the speaker shown in fig. 5 and 6 is that: the flange 12 of the speaker in the second embodiment has a hollow structure, and specifically, a side surface of the flange 12 away from the first connection wall 331 is provided with a cavity 120. Thus, the flange 12 can be formed by bending the edge of the side wall 14 of the basin frame, so that the flange 12 can be formed without removing the material on the basin frame 1, thereby being beneficial to saving the manufacturing material of the basin frame 1 and reducing the production cost.
As for the other structures of the speaker in the second embodiment, the structure of the speaker in the first embodiment may be specifically referred to, and will not be described in detail herein.
As shown in fig. 9 to 13, fig. 9 is a schematic perspective view of a speaker in a third embodiment of the present application, fig. 10 is a partially enlarged view of the speaker in fig. 9 at D, fig. 11 is a plan view of the speaker in fig. 9, fig. 12 is a sectional view of the speaker in fig. 11 at E-E, and fig. 13 is a partially enlarged view of the speaker in fig. 12 at F. The main difference between the speaker in the third embodiment of the present application and the speaker shown in fig. 5 and 6 is that: the first connecting wall 331 and the second connecting wall 332 are positioned differently with respect to the arch 31, as follows:
As shown in fig. 12 and 13, a corner 333 formed by the first connecting wall 331 and the second connecting wall 332 is connected to the outer edge of the arch 31, the first connecting wall 331 extends in a direction toward the central axis 30 of the fold ring 3, and the second connecting wall 332 is located on a side of the flange 12 away from the central axis 30 of the fold ring 3. By arranging the second connecting wall 332 on the side of the flange 12 away from the central axis 30 of the ring 3, the flange 12 can limit the movement of the second connecting wall 332 in the direction approaching the central axis 30 of the ring 3, thereby avoiding dislocation of the ring 3 during vibration. Moreover, by arranging the first connecting wall 331 to extend in a direction close to the central axis 30 of the folded ring 3, the first connecting wall 331 can be prevented from occupying the space around the arch part 31, and the outer diameter of the folded ring 3 can be made larger when the outer diameter of the loudspeaker is fixed, so that the effective vibration area Sd of the loudspeaker can be increased, and the sounding performance of the loudspeaker can be improved.
The corner 333 formed by the first connecting wall 331 and the second connecting wall 332 may be directly connected to the outer edge of the arch 31, or may be connected to the outer edge of the arch 31 through an intermediate member, for example, as shown in fig. 13, the corner 333 is connected to the outer edge of the arch 31 through a damper 8 (specifically described in detail below Wen Huiyou).
It should be noted that: the effective vibration area Sd of the loudspeaker refers to the area of the vibration part of the vibrating diaphragm 4 effectively involved in the vibration process of the loudspeaker, the effective vibration radius of the vibrating diaphragm 4 determines the effective vibration area Sd of the loudspeaker, the effective vibration radius generally refers to the radial horizontal distance from the highest point of the arched portion 31 to the central axis 30 of the folded ring 3, and when the effective vibration radius of the loudspeaker is known, the effective vibration area Sd of the loudspeaker can be obtained according to an area calculation formula. When the outer diameter of the loudspeaker is fixed, the larger the effective vibration radius is, the larger the corresponding effective vibration area Sd is, and the better the output performance of the loudspeaker is.
As for the other structures of the speaker in the third embodiment, the speaker in the first embodiment may be specifically referred to, and will not be described in detail herein.
As shown in fig. 14 and 15, fig. 14 is a sectional view of a speaker in a fourth embodiment of the present application, and fig. 15 is a partial enlarged view of the speaker at G in fig. 14. The main difference between the speaker in the fourth embodiment of the present application and the speaker shown in fig. 5 and 6 is that: the first connecting wall 331 and the second connecting wall 332 are positioned differently with respect to the arch 31, as follows:
As shown in fig. 15, the first connecting wall 331 is connected to the outer edge of the arch portion 31, the first connecting wall 331 extends in a direction approaching the central axis 30 of the hinge 3, and the second connecting wall 332 is located on a side of the flange 12 approaching the central axis 30 of the hinge 3 and is connected to the first connecting wall 331.
By disposing the second connecting wall 332 on the side of the flange 12 close to the central axis 30 of the gimbal 3, the flange 12 can limit the second connecting wall 332 to move away from the central axis 30 of the gimbal 3 during the vibration of the gimbal 3, so as to avoid dislocation of the gimbal 3 during the vibration. Moreover, by arranging the first connecting wall 331 to extend in a direction close to the central axis 30 of the folded ring 3, the first connecting wall 331 can be prevented from occupying the space around the arch part 31, and when the outer diameter size of the loudspeaker is fixed, the outer diameter of the folded ring 3 can be made larger, which is beneficial to increasing the effective vibration area Sd of the loudspeaker, so as to improve the sounding performance of the loudspeaker.
The first connecting wall 331 may be directly connected to the outer edge of the arch 31, or may be connected to the outer edge of the arch 31 through an intermediate member, such as shown in fig. 15, where the first connecting wall 331 is connected to the outer edge of the arch 31 through the damper 8.
As shown in fig. 15, the ring 3 moves along the axial direction Z of the frame 1 along with the diaphragm 4 during operation, and when the vibration amplitude is large, the deformation generated by the arched portion 31 of the ring 3 is large. For example, as shown in fig. 15, when the folder 3 moves vertically downward along the axial direction Z of the tub 1, the arch 31 may be pulled downward to interfere with the first connection wall 331, which may affect the normal vibration of the folder 3.
To solve the problem of structural interference between the arch 31 and the first connecting wall 331, in some embodiments, as shown in fig. 14 and 15, along the thickness direction Z of the first connecting wall 331, the first connecting wall 331 is disposed obliquely to the axial direction Z of the fold ring 3 near the surface 3311 of the arch 31, so that the thickness of the first connecting wall 331 gradually decreases along the direction near the central axis 30 of the fold ring 3 (for example, the thickness of the first connecting wall 331 gradually decreases along the horizontal rightward direction as shown in fig. 15). So set up, can make the surface 3311 of first connecting wall 331 slope to the direction of keeping away from arch 31, the surface 3311 of first connecting wall 331 can leave certain dodging the space for the deformation of arch 31 like this to can effectively avoid book ring 3 take place to warp the back in vibration process and produce structural interference with the surface 3311 of first connecting wall 331, in order to influence the normal vibration of book ring 3, and then can guarantee the sound performance of speaker.
As for the other structure of the speaker in the fourth embodiment, the structure of the speaker in the first embodiment may be specifically referred to, and will not be described in detail herein.
As shown in fig. 16 and 17, fig. 16 is a sectional view of a speaker in a fifth embodiment of the present application, and fig. 17 is a partial enlarged view of the speaker in fig. 16 at H. The main difference between the speaker in the fourth embodiment of the present application and the speaker shown in fig. 5 and 6 is that: the frame connection part 33 is different in structure, and is described as follows:
as shown in fig. 16 and 17, the frame connecting portion 33 includes two third connecting walls 334, a positioning groove into which the flange 12 extends is formed between the two third connecting walls 334, and the two third connecting walls 334 are respectively connected to two opposite side surfaces 123 of the flange 12 in a one-to-one correspondence manner, wherein the positioning space 330 is the positioning groove.
By extending the flange 12 into the positioning groove, the flange 12 can play a better limiting role on the frame connecting portion 33 in the groove width direction (for example, the X direction in fig. 17) of the positioning groove, and the frame connecting portion 33 is prevented from shaking, so that the frame connecting portion 33 is positioned on the flange 12 more stably, and connection reliability between the frame connecting portion 33 and the flange 12 is improved.
In some embodiments, as shown in fig. 16 and 17, in the second cross section, the two third connecting walls 334 are V-shaped overall, and the corner portion 336 formed by the two third connecting walls 334 is connected with the outer edge of the arch portion 31. Wherein the second section is a section passing through each point on the central axis of the folded ring 3 and intersecting both of the third connecting walls 334, such as the E-E section shown in fig. 16.

Meanwhile, the flange 12 can also play a better limiting role on the basin frame connecting part 33 in the X direction, so that the basin frame connecting part 33 is prevented from shaking, and the basin frame connecting part 33 is positioned on the flange 12 more stably.
The corner portion 336 formed by the two third connecting walls 334 may be directly connected to the outer edge of the arched portion 31, or may be connected to the outer edge of the arched portion 31 through an intermediate member, such as the corner portion 336 is connected to the outer edge of the arched portion 31 through the damper 8 as shown in fig. 17.
In some embodiments, as shown in fig. 17, the included angle between the two third connecting walls 334 is within 45 degrees (e.g., 30 degrees) in the second cross-section. So arranged, the third connecting wall 334 located at the inner side can provide more movement space for the arch portion 31, and structural interference between the arch portion 31 and the third connecting wall 334 located at the inner side can be better avoided.
As for the other structure of the speaker in the fifth embodiment, the structure of the speaker in the first embodiment may be specifically referred to, and will not be described in detail herein.
As shown in fig. 18 and 19, fig. 18 is a sectional view of a speaker in a sixth embodiment of the present application, and fig. 19 is a partial enlarged view of the speaker at I in fig. 18. The main difference between the speaker in the fifth embodiment of the present application and the speaker shown in fig. 16 and 17 is that: the two third connecting walls 334 are connected by a fourth connecting wall 337, as follows:

As shown in fig. 19, the extending directions of the two third connecting walls 334 may be at a certain angle, for example, within 30 degrees, but the extending directions of the two third connecting walls 334 may be parallel.
By the arrangement, the basin frame connecting part 33 can be connected with the three surfaces on different sides of the flange 12, so that the connection area of the basin frame connecting part 33 and the flange 12 is further increased, the connection strength between the basin frame connecting part 33 and the flange 12 is higher, and the connection reliability between the basin frame connecting part 33 and the flange 12 is further improved. Meanwhile, by arranging the two third connecting walls 334 along the direction X, the flange 12 can play a better limiting role on the frame connecting portion 33 in the direction X perpendicular to the central axis 30 of the folding ring 3, and the frame connecting portion 33 is prevented from shaking, so that the frame connecting portion 33 is more stably positioned on the flange 12.
In some embodiments, as shown in fig. 18 and 19, a third connecting wall 334 located on a side of flange 12 away from central axis 30 of fold ring 3 is connected to an outer edge of arch 31. By the arrangement, the fourth connecting wall 337 can extend to the side close to the central axis 30 of the folded ring 3, so that the fourth connecting wall 337 is prevented from additionally occupying the space around the arch part 31, and the outer diameter of the folded ring 3 can be made larger when the outer diameter of the loudspeaker is fixed, thus being beneficial to increasing the effective vibration area Sd of the loudspeaker and improving the sounding performance of the loudspeaker.
The third connecting wall 334 on the side of the flange 12 away from the central axis 30 of the ring 3 may be directly connected to the outer edge of the arch 31, or may be connected to the outer edge of the arch 31 through an intermediate member, for example, as shown in fig. 19, the third connecting wall 334 on the side of the flange 12 away from the central axis 30 of the ring 3 is connected to the outer edge of the arch 31 through the damper 8.
Of course, in addition to the above-described structure, the third connecting wall 334 located on the side of the flange 12 near the central axis 30 of the fold ring 3 may be connected to the outer edge of the arched portion 31.
In addition to extending toward the opening 11, the flange 12 in this embodiment may also extend in a direction perpendicular to the central axis of the frame 1, and the frame connecting portion 33 may be modified in an adaptive manner, so that the flange 12 may extend into the positioning space 330 of the frame connecting portion 33.
In some embodiments, as shown in fig. 9, 10 and 13, the frame connection part 33 is connected to the outer edge of the arched part 31 through the damper 8. Through setting up attenuator 8, the vibration of the outward flange department of arch portion 31 can be played the cushioning effect to attenuator 8, is favorable to reducing the outward flange of arch portion 31 and to the pulling force of basin frame connecting portion 33, avoids the outward flange of arch portion 31 to the too big and fracture between messenger arch portion 31 and the basin frame connecting portion 33 of pulling force of basin frame connecting portion 33 to be favorable to improving the life of speaker.

The third section is a section passing through each point on the central axis of the folded ring 3 and intersecting with the damper 8 and the frame connecting portion 33, such as an E-E section shown in fig. 12. The damper 8 has elasticity, and the damper 8 may be made of rubber or a material such as silica gel, and is not particularly limited.
By arranging the first curved surface 81 and the second curved surface 82 which are curved, the transition of the joint of the damper 8, the arched part 31 and the basin frame connecting part 33 is gentle, so that the stress of the joint of the damper 8, the arched part 31 and the basin frame connecting part 33 can be reduced in the vibration process of the folding ring 3, and the fracture probability between the damper 8 and the arched part 31 and between the damper 8 and the basin frame connecting part 33 can be further reduced.
In some embodiments, as shown in fig. 13, in the third section, the first curved surface 81 and the second curved surface 82 are both arc lines. The first curved surface 81 and the second curved surface 82 are both set as a part of an arc line, and in the production and processing process, particularly in the existing digital processing mode, a set curve formula can be directly called for processing, compared with an irregular curve, the method saves related calculation steps, facilitates processing, and is beneficial to improving the processing efficiency.
In some embodiments, in the third cross-section, the first curved surface 81 and the second curved surface 82 are each part of an elliptic curve.

In some embodiments, as shown in fig. 15 and 19, a transition fillet 83 is provided at the junction of the damper 8 and the basin stand connection 33. By arranging the transition fillets 83, the transition at the joint of the damper 8 and the basin frame connecting part 33 is more gentle, so that the stress at the joint of the damper 8 and the basin frame connecting part 33 can be further reduced in the vibration process of the folding ring 3, and the fracture probability between the damper 8 and the basin frame connecting part 33 can be further reduced.

Meanwhile, the damper 8, the arched part 31 and the basin frame connecting part 33 are of an integrated structure, so that the number of parts in the loudspeaker can be reduced, assembly steps can be saved, and the assembly efficiency of the loudspeaker can be improved.
Of course, a certain number of dampers 8 and frame connecting portions 33 may be provided at intervals around the opening 11, each frame connecting portion 33 being connected to the arch portion 31 through a corresponding damper 8. The damper 8, the arch 31 and the frame connection 33 may be designed separately and then connected together by means of adhesive, snap connection, etc.

The following comparison is made with respect to overall performance data of speaker structures in various embodiments of the present application, and the overall performance data of the speaker structures are shown in the following table:
wherein, the data of the overall performance of the speaker structure comprises Sd and Mms; the scheme shown in fig. 1 is referred to as a scheme one, the schemes shown in fig. 3 to 6 are referred to as a scheme two, the schemes shown in fig. 9 to 13 are referred to as a scheme three, the schemes shown in fig. 16 and 17 are referred to as a scheme four, and the schemes shown in fig. 14 and 15 are referred to as a scheme five.
In the above table, sd represents the effective vibration area of the diaphragm 4 during vibration of the speaker.
Mms represents the vibration mass, also called equivalent mass, and refers to the mass sum of all parts of the loudspeaker participating in vibration in the motion process, including the vibrating diaphragm 4, the folded ring 3, the voice coil 52, the elastic wave 61, the air mass participating in vibration and the like.
The sensitivity of a speaker generally refers to the sound pressure measured at 1 meter in front of the axis Z of the speaker when the input power is 1W, i.e., the sound pressure level is measured as to how many decibels of sound pressure can be generated at 1 meter in front of the axis Z of the speaker; the higher the sensitivity the loudspeaker is, the more the loudspeaker is able to respond to all details in the audio current signal, i.e. the higher the sensitivity the higher the electroacoustic conversion efficiency, e.g. the higher the sensitivity the higher the sound can be made when the input power is the same.
As shown in the above table, the effective vibration area Sd of the speaker of the second scheme is increased by 13% as compared with the Sd of the first scheme, and the Sd of the third, fourth and fifth schemes are respectively increased by 21% as compared with the Sd of the first scheme; the sensitivity of the loudspeaker in the second scheme is improved by 0.55dB/W compared with that in the first scheme, and the sensitivity in the third scheme, the fourth scheme and the fifth scheme is improved by 1.1dB/W compared with that in the first scheme. That is: under the condition that the outer diameter sizes of the speakers are the same, the speakers in the second to fifth schemes can achieve larger effective vibration area and higher sensitivity, and are beneficial to improving the overall performance of speaker products.
In addition, the vibration mass (Mms) of the speaker in the first scheme was 1.9g, while the vibration mass of the speaker in the second scheme was increased to 2.1g, and the vibration masses in the third, fourth and fifth schemes were all increased to 2.24g. The vibration mass of a speaker is generally inversely proportional to the resonance frequency, and the larger the vibration mass of the vibration system 2 of the speaker, the lower the resonance frequency, wherein the resonance frequency is the lowest frequency that the speaker can reproduce, and is an important parameter that determines the low frequency characteristics of the speaker, and the lower the resonance frequency, the better the texture and strength of the bass reproduced by the speaker. Therefore, the speakers in the second to fifth embodiments can provide a larger vibration mass, and the corresponding resonance frequency is lower, so that better sound quality and strength can be provided for users in bass.
