Description

Technical Field

[0001] The invention relates to the field of sound-to-electricity conversion, and in particular to an off-axis coaxial loudspeaker and an assembly method thereof. Background Art

[0002] A speaker is a transducer that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but it is also the most important component for the sound effect. There are many types of speakers, and the prices vary greatly. Audio electrical energy vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects, and resonates with the surrounding air to produce sound.

[0003] Traditional speakers have the problem of diffraction interference, that is, the wavelength of the speaker's sound electricity and the distance from the speaker panel cause the frequency to overlap, making the music or sound in the ear not harmonious. The current solutions include setting the speaker in a spherical shape, using a wide baffle and placing it against the wall, placing the driver in a non-center position in the speaker box, placing a waveguide similar to a short speaker in front of the tweeter, adding some sound-absorbing materials around the tweeter to reduce diffraction interference or using ground reflection, etc. These methods all rely on additional material resources or environmental conditions to solve the diffraction interference problem of the speaker, rather than solving the problem based on the parts of the speaker itself.

[0077] Embodiment 1:

[0078] Reference Figure 1 and attached Fig.10 As shown, an off-axis coaxial speaker according to a preferred embodiment of the present invention is schematically shown. The off-axis coaxial speaker 1 is an electroacoustic conversion device that can convert electrical energy into sound. When the off-axis coaxial speaker 1 is used, there is no need to worry about the design of the box, so that the design engineer of the rectangular sound box can place the off-axis coaxial speaker 1 at any position and assemble it at will, which can reduce or even avoid the problem of diffraction interference and make the sound clearer.

[0079] Figure 1 1 is a schematic diagram of the overall structure of the eccentric coaxial loudspeaker 1 according to the first preferred embodiment of the present invention. In this embodiment, the eccentric coaxial loudspeaker 1 includes an outer frame 10, a mid-bass device 20 and a tweeter 30, the mid-bass device 20 and the tweeter 30 are arranged in the outer frame 10, the mid-bass device 20 is suitable for converting electrical energy into mid-bass sound signals and transmitting them, and the tweeter 30 is suitable for converting electrical energy into tweeter sound signals and transmitting them.

[0080] As is well known, the speaker frequency in the frequency range of 2560 Hz to 5120 Hz is treble, and the frequency range above 5120 Hz is super treble. The tweeter device 30 of the present invention is suitable for providing high frequency band sound effects above 2560 Hz, and is thus defined as the tweeter device 30. The mid-bass device 20 is suitable for providing sounds recognizable by human ears from 20 Hz to 2560 Hz.

[0081] For ease of explanation, in this embodiment, the axis where the center of gravity of the outer frame 10 of the eccentric coaxial speaker 1 is located is used as the central axis 90 of the eccentric coaxial speaker 1, and the axis where the center of gravity of the mid-bass device 20 and the tweeter 30 of the eccentric coaxial speaker 1 is located is used as the driving axis 80 of the eccentric coaxial speaker 1. The driving axis 80 of the eccentric coaxial speaker 1 is defined as the driving axis 80 of the mid-bass device 20 and the tweeter 30. The central axis 90 of the eccentric coaxial speaker 1 is defined as the central axis 90 of the outer frame 10.

[0082] That is to say, the mid-bass device 20 and the tweeter device 30 of the eccentric coaxial speaker 1 are on the same driving axis 80, and the mid-bass device 20 and the tweeter device 30 deviate from the central axis 90 of the eccentric coaxial speaker 1, so that the eccentric coaxial speaker 1 can solve the diffraction interference problem of superimposed frequencies caused by equidistant frequencies, making the sound clearer and cleaner.

[0083] The outer frame 10 includes an upper frame 11, a lower frame 12, an upper fixing frame 13 and a lower fixing frame 14. The upper fixing frame 13 is disposed at the upper end of the upper frame 11, and the lower fixing frame 14 is disposed between the upper frame 11 and the lower frame 12. In other words, the upper frame 11 and the lower frame 12 are connected and fixed to each other through the lower fixing frame 14. The mid-bass device 20 and the tweeter device 30 are installed in the area between the upper frame 11 and the lower frame 12.

[0084] The mid-bass device 20 includes a suspension component 21, a vibration component 22, a mid-bass voice coil 23, a spring 24 and a magnetic return unit 25, wherein the suspension component 21, the vibration component 22, the mid-bass voice coil 23, the spring 24 and the magnetic return unit 25 are all arranged in the outer frame 10. During the sound generation process of the mid-bass device 20 of the eccentric coaxial speaker 1, the magnetic return unit 25 is excited to drive the mid-bass voice coil 23 to move, and the movement of the mid-bass voice coil 23 causes the vibration of the vibration component 22. The vibration of the vibration component 22 then causes the fluctuation of the air medium, thereby generating different audio frequencies. These audio frequencies reach the human ear and become mid-bass sound signals. The suspension component 21 and the vibration component 22 are both installed in the upper frame 11, and the suspension component 21 is arranged at the upper end of the vibration component 22 to limit the range of movement of the vibration component 22 and ensure that the vibration component 22 reciprocates along the driving axis 80 of the eccentric coaxial speaker 1, thereby ensuring that the sound of the eccentric coaxial speaker 1 is clear and clean.

[0085] The upper frame 11 includes an annular platform 111, a plurality of fixed connectors 112 and a plurality of extended connectors 113, wherein the fixed connectors 112 and the extended connectors 113 protrude and extend downward from the bottom end of the annular platform 111 in a circular shape, that is, the fixed connectors 112 and the extended connectors 113 are arranged in a circular shape at the bottom of the annular platform 111. The length of each of the fixed connectors 112 is consistent, and correspondingly, the length of each of the extended connectors 113 is consistent, and the length of the extended connectors 113 is greater than the length of the fixed connectors 112. The vibration assembly 22 is mounted on the annular platform 111, and the suspension assembly 21 is disposed at the upper end of the annular platform 111 to limit the range of motion of the vibration assembly 22.

[0086] The lower frame 12 includes a magnetic return mounting platform 121, a connecting seat 122, a plurality of fixing protrusions 123 and a plurality of fixing locks 124. The magnetic return mounting platform 121 is arranged in the connecting seat 122, the magnetic return unit 25 is installed in the magnetic return mounting platform 121, the fixing protrusion 123 protrudes upward from the upper end of the connecting seat 122, and the fixing protrusion 123 is connected to the fixing connector 112 of the upper frame 11, and is suitable for being locked and fixed by the fixing lock 124. In other words, the fixing connector 112 and the fixing protrusion 123 are locked and fixed by the fixing lock 124, thereby connecting and fixing the upper frame 11 and the lower frame 12 to each other.

[0087] The lower fixing frame 14 includes a fixing ring 141, a plurality of fixing grooves 142 and a damper installation area 143. The fixing groove 142 is recessed downward from the top side of the fixing ring 141 to penetrate the fixing ring 141. The damper installation area 143 is recessed downward from the top middle of the fixing ring 141 to penetrate the fixing ring 141. The damper 24 is installed in the damper installation area 143. The fixing protrusion 123 of the lower frame 12 is suitable for being engaged in the fixing groove 142, so that the lower fixing frame 14 is connected and fixed to the lower frame 12.

[0088] The center of gravity of the upper frame 11, the connection seat 122 of the lower frame 12, the upper fixed frame 13 and the lower fixed frame 14 is located on the central axis 90 of the eccentric coaxial speaker 1, and the center of gravity of the magnetic return mounting platform 121 of the lower frame 12 deviates from the central axis 90 of the eccentric coaxial speaker 1 and is located on the driving axis 80 of the eccentric coaxial speaker 1. Based on this, the central axis 90 of the eccentric coaxial speaker 1 is defined as the central axis 90 of the upper frame 11, the connection seat 122 of the lower frame 12, the upper fixed frame 13 and the lower fixed frame 14.

[0089] It is worth mentioning that the elastic wave 24 can maintain the correct position of the mid-bass voice coil 23 in the magnetic return unit 25, ensuring that when the mid-bass voice coil 23 is subjected to force, the vibration assembly 22 reciprocates axially and can prevent dust from entering the magnetic return unit 25.

[0090] It is worth mentioning that, in this embodiment, the fixing protrusion 123 of the lower frame 12 and the fixing groove 142 of the lower fixing frame 14 are engaged with each other, and the fixing connector 112 of the upper frame 11 is connected to the fixing protrusion 123 of the lower frame 12 through the fixing lock 124, so that the upper frame 11 and the lower frame 12 are fixed to each other. In addition, the extending connector 113 of the upper frame 11 is connected to the connecting seat 122 of the lower frame 12, so as to further connect the upper frame 11 and the lower frame 12.

[0091] Among them, in this embodiment, the number of the fixed connector 112, the fixed lock buckle 124 and the fixed protrusion 123 is set to two. In this regard, those skilled in the art should understand that the number of the fixed connector 112, the fixed lock buckle 124 and the fixed protrusion 123 is not a limitation of the present invention.

[0092] Furthermore, the center of gravity of the upper frame 11, the connecting seat 122 of the lower frame 12, the upper fixed frame 13 and the lower fixed frame 14 are located on the central axis 90. In addition, the center of gravity of the magnetic return mounting platform 121 is located on the driving axis 80, and the magnetic return unit 25 is installed on the magnetic return mounting platform 121. The magnetic field generated by the magnetic return unit 25 drives the mid-bass voice coil 23 to move, and the movement of the mid-bass voice coil 23 causes the vibration of the vibration component 22. The vibration of the vibration component 22 further causes the fluctuation of the air medium, thereby generating different audio frequencies. These audio frequencies become mid-bass sound signals when they reach the human ear, so as to ensure the clarity of the sound signal of the eccentric coaxial speaker 1.

[0093] The suspension component 21 has an inner suspension unit 211 and an outer suspension unit 212, wherein the inner suspension unit 211 and the outer suspension unit 212 are an integrated structure, and the vibration component 22 includes a driving unit 221 and a fixing unit 222, wherein the inner suspension unit 211 of the suspension component 21 extends inwardly to be connected to the fixing unit 222 of the vibration component 22, and correspondingly, the outer suspension unit 212 of the suspension component 21 extends outwardly to be connected to the annular platform 11 of the upper frame 11. In other words, the vibration component 22 is connected and fixed to the upper frame 11 through the suspension component 21. The suspension component 21 is used to limit the range of motion of the vibration component 22 and ensure that the vibration component 22 reciprocates along the driving axis 80 of the eccentric coaxial speaker 1, so as to ensure that the sound of the eccentric coaxial speaker 1 is clear and clean.

[0094] The vibration component 22 further has a near driving end 223 and a far driving end 224, wherein, in the present embodiment, the near driving end 223 is defined as a side of the fixing unit 222 of the vibration component 22 close to the driving axis 80 of the eccentric coaxial speaker 1, and correspondingly, the far driving end 224 is defined as a side of the fixing unit 222 of the vibration component 22 away from the driving axis 80 of the eccentric coaxial speaker 1.

[0095] It is worth mentioning that, in this embodiment, the thickness of the vibration component 22 is not uniform. Specifically, the thickness of the vibration component 22 gradually becomes thinner from the near driving end 223 to the far driving end 224, that is, the thickness of the near driving end 223 of the vibration component 22 is greater than the thickness of the far driving end 224. Based on this, the center of gravity of the vibration component 22 can be located on the driving axis 80 of the eccentric coaxial loudspeaker 1, that is, the vibration component 22 deviates from the central axis 90 of the eccentric coaxial loudspeaker 1. Then, when the magnetic return unit 25 is excited to drive the mid-bass voice coil 23 to move, and the movement of the mid-bass voice coil 23 causes the vibration of the vibration component 22, the driving unit 221 of the vibration component 22 can reciprocate from the driving axis 80, and the vibration component 22 can remain horizontal to avoid tilting, thereby ensuring that the sound quality of the mid-bass device 20 is clear and clean.

[0096] The mid-bass voice coil 23 has an upper voice coil portion 231 and a lower voice coil portion 232, and the upper voice coil portion 231 and the lower voice coil portion 232 are integrally connected, that is, the upper voice coil portion 231 is defined as the upper portion of the mid-bass voice coil 23, and the lower voice coil portion 232 is defined as the lower portion of the mid-bass voice coil 23. In addition, the magnetic return unit 25 has a magnetic gap 251, and the lower voice coil portion 232 of the mid-bass voice coil 23 is extended and connected to the magnetic gap 251 of the magnetic return unit 25, and the upper voice coil portion 231 of the mid-bass voice coil 23 is extended and connected to the driving unit 221 of the vibration assembly 22, and the magnetic return unit 25 and the lower voice coil portion 232 of the mid-bass voice coil 23 can be magnetically connected to each other.

[0097] Based on this, when the eccentric coaxial speaker 1 receives an electrical signal, that is, the magnetic return unit 25 and the lower part 232 of the mid-bass voice coil 23 are in magnetic communication with each other, and the lower part 232 of the mid-bass voice coil 23 is transmitted to the upper part 231 of the voice coil, and the upper part 231 of the voice coil drives the vibration of the vibration component 22, and the vibration of the vibration component 22 causes the fluctuation of the air medium, thereby generating mid-bass and transmitting it to the user's ears.

[0098] Preferably, in this embodiment, the center of gravity of the suspension component 21, the vibration component 22, the mid-bass voice coil 23, the elastic wave 24 and the magnetic return unit 25 are all on the driving axis 80 of the eccentric coaxial speaker 1, that is, the center of gravity of the suspension component 21, the vibration component 22, the mid-bass voice coil 23, the elastic wave 24 and the magnetic return unit 25 are all deviated from the central axis 90 of the eccentric coaxial speaker 1, so that the eccentric coaxial speaker 1 can solve the diffraction interference problem caused by the superimposed frequency due to equidistant spacing, making the sound clearer and cleaner. Therefore, the eccentric coaxial speaker 1 is no longer troubled by the box design when in use, so that the design engineer of the rectangular speaker can place the eccentric coaxial speaker 1 at any position and assemble it at will, which can reduce the problem of diffraction interference.

[0099] Preferably, in the present embodiment, the vibration component 22 is manufactured by injection molding, based on which the thickness of the vibration component 22 can be gradually thinned from the proximal driving end 223 to the distal driving end 224. The suspension component 21 can be connected and fixed by an adhesion unit 70, or can be integrally arranged between the vibration component 22 and the annular platform 111 of the upper frame 11. Preferably, in the present embodiment, the adhesion unit 70 can be set as a glue. The inner suspension unit 211 of the suspension component 21 is connected to the vibration component 22 through the adhesion unit 70, and the outer suspension unit 212 of the suspension component 21 is connected to the annular platform of the upper frame 11 through the adhesion unit 70.

[0100] Specifically, in this embodiment, the thickness of the proximal driving end 223 of the vibration component 22 is defined as d1, and the thickness of the distal driving end 224 of the vibration component 22 is defined as d2. According to the above description, it can be obtained that d1 is greater than d2.

[0101] Specifically, the thickness of the vibration component 22, the suspension component 21 and the adhesion unit 70 can be controlled. That is, the thickness of the vibration component 22, the suspension component 21 and the adhesion unit 70 can be controlled during manufacturing. Specifically, in this embodiment, the thickness of the vibration component 22 is set to gradually become thinner from the near drive end 223 to the far drive end 224, and the thickness of the suspension component 21 and the adhesion unit 70 is not changed in this embodiment, that is, the thickness of the suspension component 21 and the adhesion unit 70 remains consistent.

[0102] In other possible implementations, the thickness of the suspension component 21 and the adhesion unit 70 can also be changed. In a specific embodiment, the thickness of the suspension component 21 gradually becomes thinner from the proximal driving end 223 of the vibration component 22 to the distal driving end 224, and the thickness of the vibration component 22 and the adhesion unit 70 remain unchanged; in another possible implementation, the thickness of the adhesion unit 70 gradually becomes thinner from the proximal driving end 223 of the vibration component 22 to the distal driving end 224, and the thickness of the vibration component 22 and the suspension component 21 remain unchanged.

[0103] Specifically, the thickness of the suspension component 21 at the near drive end 223 of the vibration component 22 is defined as d3, and the thickness of the suspension component 21 at the far drive end 224 of the vibration component 22 is defined as d4. According to the above description, it can be obtained that d3 is greater than d4. In addition, the thickness of the adhesion unit 70 at the near drive end 223 of the vibration component 22 is defined as d5, and the thickness of the adhesion unit 70 at the far drive end 224 of the vibration component 22 is defined as d6. According to the above description, it can be obtained that d5 is greater than d6.

[0104] In summary, the thickness of one of the vibration component 22, the suspension component 21 and the adhesion unit 70 is set to gradually become thinner from the near driving end 223 of the vibration component 22 to the far driving end 224, so that the center of gravity of the structure composed of the vibration component 22, the suspension component 21 and the adhesion unit 70 is located on the driving axis 80 of the eccentric coaxial loudspeaker 1. In addition, when the vibration component 22 and the suspension component 21 are integrally formed, the thickness of the vibration component 22 and the suspension component 21 are both set to gradually become thinner from the near driving end 223 of the vibration component 22 to the far driving end 224, so that the center of gravity of the structure composed of the vibration component 22 and the suspension component 21 is located on the driving axis 80 of the eccentric coaxial loudspeaker 1. In other words, the center of gravity of the structure composed of the vibration component 22, the suspension component 21 and the adhesion unit 70 deviates from the central axis 90 of the eccentric coaxial loudspeaker 1. In this regard, those skilled in the art should understand that this is not a limitation of the present invention.

[0105] Based on this, when the mid-bass voice coil 23 drives the vibration component 22 to reciprocate from the driving axis 80 of the eccentric coaxial speaker 1, the vibration unit 22 can maintain horizontal vibration, so that the mid-bass sound emitted by the eccentric coaxial speaker 1 is clearer and cleaner.

[0106] In addition, the shape of the vibration unit 22 can be set to be a trumpet shape or a flat plate shape, which is not a limitation of the present invention.

[0107] Based on this, when the eccentric coaxial speaker 1 is installed in a box to form an audio device, because the center of gravity of the driving unit 221 of the vibration unit 22 deviates from the central axis 90 of the eccentric coaxial speaker 1, it is located on the driving axis 80 of the eccentric coaxial speaker 1. Based on this, when the eccentric coaxial speaker 1 is installed in the middle of the box, the center of gravity of the driving unit 221 of the vibration unit 22 will not be at an equal distance from the two sides of the box, which can effectively solve the diffraction problem, making the mid-bass sound quality of the eccentric coaxial speaker 1 clearer, and the eccentric coaxial speaker 1 is no longer troubled by the box design when in use, which can improve the aesthetics of the audio device.

[0108] In this embodiment, the mid-bass device 20 is suitable for emitting mid-bass sound signals, the tweeter device 30 is suitable for emitting treble sound signals, the sound wave frequency of the tweeter device 30 is between 2560 Hz and 5120 Hz, and the tweeter device 30 is disposed in the outer frame 10 .

[0109] The tweeter device 30 includes a tweeter cover 31, a tweeter equalizer 32, an aluminum column 33, a tweeter drum paper 34, a tweeter middle seat 35 and a tweeter magnet 36. The tweeter equalizer 32 is arranged in the tweeter cover 31, the tweeter cover 31 is arranged at the upper end of the aluminum column 33, the tweeter drum paper 34, the tweeter middle seat 35 and the tweeter magnet 36 are all installed in the aluminum column 33. The tweeter drum paper 34 is arranged above the tweeter middle seat 35 and is limited by the tweeter cover 31, and the tweeter magnet 36 is arranged below the tweeter middle seat 35. The tweeter device 30 of the off-axis coaxial loudspeaker 1 drives the tweeter middle seat 35 through the tweeter magnet 36, and the tweeter middle seat 35 drives the tweeter drum paper 34 to reciprocate along the driving axis 80 of the off-axis coaxial loudspeaker 1, thereby agitating the air to radiate sound waves outward, thereby realizing the treble sound of the off-axis coaxial loudspeaker 1.

[0110] The tweeter device 30 further includes a tweeter middle seat nut 37 , which is disposed at the lower end of the tweeter magnet 36 to be connected to the magnetic return unit 25 .

[0111] The inner side of the tweeter cover 31 is connected to the tweeter drum paper 34, and correspondingly, the outer side of the tweeter cover 31 is connected to the aluminum column 33, and the tweeter drum paper 34 is installed between the tweeter cover 31 and the tweeter middle seat 35. The tweeter cover 31 is used to limit the range of movement of the tweeter drum paper 34 and ensure that the tweeter drum paper 34 reciprocates along the driving axis 80 of the eccentric coaxial speaker 1, so as to ensure that the sound of the tweeter device 30 of the eccentric coaxial speaker 1 is clear and clean.

[0112] Specifically, the center of gravity of the tweeter 30 is on the driving axis 80 of the eccentric coaxial loudspeaker 1, and the center of gravity of the tweeter 30 deviates from the central axis 90 of the eccentric coaxial loudspeaker 1. Based on this, when the eccentric coaxial loudspeaker 1 is installed in a box to form an audio device, the center of gravity of the tweeter 30 will not be at equal distances from both sides of the box, which can effectively solve the diffraction problem, making the sound quality of the treble sound emitted by the eccentric coaxial loudspeaker 1 clearer, and the eccentric coaxial loudspeaker 1 is no longer troubled by the box design when in use, which can improve the aesthetics of the audio device.

[0113] More specifically, that is to say, the tweeter magnet 36 drives the tweeter center seat 35, and the tweeter center seat 35 drives the tweeter drum paper 34 to reciprocate along the driving axis 80 of the eccentric coaxial speaker 1, thereby agitating the air to radiate sound waves outward, thereby realizing the treble sound of the eccentric coaxial speaker 1. Based on this, the center of gravity of the tweeter magnet 36, the tweeter drum paper 34 and the tweeter center seat 35 are all on the driving axis 80 of the eccentric coaxial speaker 1 and deviate from the central axis 90 of the eccentric coaxial speaker 1.

[0114] It is worth mentioning that the treble equalizer 32 can disperse the treble sound waves emitted by the off-axis coaxial speaker 1, and disperse the relatively concentrated sound waves emitted by the off-axis coaxial speaker 1 to all angles, so that the sound waves of the speaker can have a wider divergence area, so that the audience can enjoy a better listening experience, and the off-axis coaxial speaker 1 equipped with the treble equalizer 32 can create a stereo surround sound effect for the audience. In addition, the treble equalizer 32 can prevent external sound waves from interfering with the sound waves emitted by the tweeter device 30, which is conducive to the tweeter device 30 providing a purer treble sound quality.

[0115] It is worth mentioning that, in this embodiment, the tweeter drum paper 34 is manufactured by injection molding. The tweeter cover 31 can be connected and fixed by an adhesive unit 70, or can be integrally arranged between the tweeter drum paper 34 and the aluminum column 33. Therefore, in the tweeter device 30, the thickness of the tweeter drum paper 34, the tweeter cover 31 and the adhesive unit 70 can also be controlled and changed. In addition, in the present embodiment, since the center of gravity of the tweeter device 30 has deviated from the central axis 90 of the eccentric coaxial speaker 1, the thickness of the tweeter drum paper 34, the tweeter cover 31 and the adhesion unit 70 can be kept consistent. In this regard, those skilled in the art should understand that, in the tweeter device 30, the thickness variation of the tweeter drum paper 34, the tweeter cover 31 and the adhesion unit 70 is not a limitation of the present invention. It is only necessary to ensure that the tweeter device 30 and the mid-bass device 20 are on the same driving axis 80, and the mid-bass device 20 and the tweeter device 30 deviate from the central axis 90 of the eccentric coaxial speaker 1.

[0116] To sum up, the mid-bass device 20 and the tweeter device 30 of the eccentric coaxial speaker 1 are on the same driving axis 80, and the mid-bass device 20 and the tweeter device 30 deviate from the central axis 90 of the eccentric coaxial speaker 1, so that the eccentric coaxial speaker 1 can solve the diffraction interference problem of superimposed frequencies caused by equidistant frequencies, making the sound clearer and cleaner, and the sound quality better.
