BEST MODE FOR CARRYING OUT THE INVENTION
-1st Embodiment-
Hereinafter, a first embodiment in which a speaker device according to the present invention is applied to an in-vehicle speaker device will be described with reference to FIGS. FIG. 1 is a cross-sectional view illustrating the speaker device according to the first embodiment.
[0014]
As shown in FIG. 1, a dynamic speaker unit 10 constituting a speaker device 100 according to a first embodiment includes a frame 1 fastened to a mounting panel 20 via a cushion material 1a at an outer peripheral portion, and a frame 1 attached to the frame 1. A magnetic circuit 2, a voice coil 3 accommodated in a magnetic gap of the magnetic circuit 2, a damper 5 provided between the voice coil 3 and the frame 1, and supporting the voice coil 3 so as to vibrate; A diaphragm 6 is connected to the coil 3, and an edge 7 is provided between the outer peripheral portion of the diaphragm 6 and the frame 1 and supports the diaphragm 6 so that it can vibrate.
[0015]
As shown in FIG. 1, the magnetic circuit 2 includes a ring-shaped magnet 2a, and forms an external magnet type magnetic circuit. By passing a current through the winding 3a of the voice coil 3, the vibration system including the diaphragm 6 can be vibrated in the left-right direction in FIG. 1 to generate an acoustic output.
[0016]
The frame 1 has a shape whose outer diameter decreases from the outer peripheral portion fastened to the mounting panel 20 toward the magnetic circuit 2. Dynamic vibration absorbers 31 and 32 are attached to the frame 1 near the magnetic circuit 2.
[0017]
As shown in FIG. 1, the dynamic vibration absorber 31 includes a spring portion 31a having one end attached to the frame 1, and a weight portion 31b attached to the other end of the spring portion 31a. The dynamic vibration absorber 32 includes a spring portion 32a having one end attached to the frame 1 and a weight portion 32b attached to the other end of the spring portion 32a. The resonance frequency of the dynamic vibration absorber 31 is determined by the compliance of the spring portion 31a and the mass of the weight portion 31b, and the resonance frequency of the dynamic vibration absorber 32 is determined by the compliance of the spring portion 32a and the mass of the weight portion 32b. The dynamic vibration absorbers 31 and 32 have a function of controlling the vibration of the magnetic circuit 2 and the frame 1 via the frame 1 to improve the acoustic characteristics.
[0018]
The mounting panel 20 is a member constituting a vehicle door, and is not designed in consideration of acoustic performance. Therefore, the mounting panel 20 relatively easily vibrates, and the speaker unit 10 is hard to be firmly fixed. For this reason, in the present embodiment, the vibrations of the speaker unit 10 are suppressed by the dynamic vibration absorbers 31 and 32, and good acoustic characteristics are obtained as the whole of the speaker device 100.
[0019]
2 to 4 show vibration acceleration levels of the mounting panel 20 when the dynamic vibration absorbers 31 and 32 are not mounted. 2 shows the mounting panel 20, FIG. 3 shows the vibration acceleration level of the mounting panel surface at point A shown in FIG. 2, and FIG. 4 shows the vibration acceleration level of the mounting panel surface at point B shown in FIG. FIG.
[0020]
3 and 4 show the results of measuring the vibration acceleration levels at points A and B, respectively, with the acceleration pickup mounted at point A or point B with the speaker unit 10 mounted on the mounting panel 20. Such vibration characteristics include those in which the mounting panel 20 is vibrated by sound pressure radiated from the diaphragm 6 of the speaker unit 10 and transmitted through the air, and the reaction of the vibration of the diaphragm 6 is generated in the magnetic circuit 2. It is conceivable that both of the signals transmitted to the mounting panel 20 via the frame 1 were combined.
[0021]
As shown in FIGS. 3 and 4, the mounting panel 20 has a characteristic that vibrates over a wide frequency band, and the vibration acceleration level has a maximum value at around 1 kHz. Note that the vibration acceleration level is a parameter corresponding to (proportional to) the sound pressure. However, the sound pressure level in the vehicle when the door is attached to the vehicle is a level lower than the characteristics shown in FIGS. Indicate increased characteristics.
[0022]
In the present embodiment, the vibrations of the magnetic circuit 2 and the frame 1 are reduced by attaching the dynamic vibration absorbers 31 and 32, and the vibration acceleration level of the mounting panel 20 can be largely suppressed. The resonance frequency of the dynamic vibration absorbers 31 and 32 may be matched with a frequency (for example, about 1 kHz) at which the vibration acceleration level of the mounting panel 20 becomes maximum between 50 Hz and 3000 Hz. Further, the resonance frequency of the dynamic vibration absorbers 31 and 32 may be set within a range of one octave above and below the frequency at which the vibration acceleration level of the mounting panel 20 becomes maximum between 50 Hz and 3000 Hz. Furthermore, the resonance frequency of the dynamic vibration absorbers 31 and 32 may be matched with the frequency at which the vibration of the mounting panel 20 should be attenuated in sound quality between 50 Hz and 3000 Hz, or the resonance frequency of the dynamic vibration absorbers 31 and 32 may be It may be set within a range of one octave above and below the frequency to be attenuated for sound quality. In this case, the frequency may be one octave or more away from the frequency at which the vibration acceleration level of the mounting panel 20 is highest.
[0023]
Further, the resonance frequency of the dynamic vibration absorber 32 may be set to a frequency different from the resonance frequency of the dynamic vibration absorber 31.
[0024]
The spring portions 31a and 32a of the dynamic vibration absorbers 31 and 32 are desirably formed of a material having a larger loss tangent (Tan δ) than the mounting panel 20, the frame 1, or the magnetic circuit 2. By forming the spring portions 31a and 32a from a material having a large loss tangent, resonance of the spring portions 31a and 32a at a specific frequency can be prevented, and vibration of the frame 1 and the magnetic circuit 2 can be suppressed. Similar effects can be obtained by damping the spring portions 31a and 32a with a material having a larger loss tangent than the mounting panel 20, the frame 1, or the magnetic circuit 2.
[0025]
As shown in FIG. 1, in the present embodiment, the inner diameter L1 of the mounting hole 20a of the mounting panel 20 formed for mounting the speaker unit 10 is smaller than the inner diameter L1 of the dynamic vibration absorbers 31 and 32. The outer diameter L2 is smaller. Therefore, the speaker unit 10 can be mounted from the front side (the left side in FIG. 1) of the mounting panel 20 without the work being hindered by the dynamic vibration absorbers 31 and 32 when the speaker unit 10 is mounted.
[0026]
Since the characteristics of the speaker device 100 when actually reproduced in the vehicle become a problem, the resonance of the dynamic vibration absorbers 31 and 32 is determined based on the vibration acceleration level of the mounting panel 20 with the door mounted on the vehicle. It is preferable to set the frequency.
[0027]
As described above, in the present embodiment, the dynamic vibration absorbers 31 and 32 are attached to the frame 1 and the resonance frequency thereof is set to a predetermined frequency, so that the vibration of the frame 1 and the magnetic circuit 2 can be effectively suppressed. . For this reason, it is possible to suppress disturbance of the frequency characteristics and the like due to the vibration of the frame 1 and the magnetic circuit 2, and it is possible to improve the acoustic characteristics of the speaker device 100.
[0028]
In the first embodiment, an example is shown in which two dynamic vibration absorbers are used, but the number of dynamic vibration absorbers is not limited to this, and may be one or three or more.
[0029]
-2nd Embodiment-
Hereinafter, a second embodiment in which the speaker device according to the present invention is applied to a vehicle-mounted speaker device will be described with reference to FIG. FIG. 5 is a cross-sectional view illustrating the speaker device according to the second embodiment. In FIG. 5, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.
[0030]
As shown in FIG. 5, the dynamic speaker unit 10 constituting the speaker device 200 of the second embodiment is fastened to the mounting panel 20 via the frame 1 and the cushion material 1a.
[0031]
On the back side (left side in FIG. 5) of the mounting panel 20, dynamic vibration absorbers 33 and 34 are mounted near the speaker unit 10. As shown in FIG. 5, the dynamic vibration absorber 33 includes a spring portion 33a having one end attached to the panel 20, and a weight portion 33b attached to the other end of the spring portion 33a. Further, the dynamic vibration absorber 34 includes a spring portion 34a having one end attached to the panel 20, and a weight portion 34b attached to the other end of the spring portion 34a. The resonance frequency of the dynamic vibration absorber 33 is determined by the compliance of the spring portion 33a and the mass of the weight portion 33b, and the resonance frequency of the dynamic vibration absorber 34 is determined by the compliance of the spring portion 34a and the mass of the weight portion 34b. The dynamic vibration absorbers 33 and 34 have a function of controlling the vibration of the panel 20 and improving the acoustic characteristics.
[0032]
In the present embodiment, by attaching the dynamic vibration absorbers 33 and 34, the vibration of the panel 20 can be reduced, and the vibration acceleration level of the attachment panel 20 can be significantly suppressed. The resonance frequency of the dynamic vibration absorbers 33 and 34 may be matched with the frequency (for example, around 1 kHz) at which the vibration acceleration level of the mounting panel 20 becomes maximum between 50 Hz and 3000 Hz. Further, the resonance frequency of the dynamic vibration absorbers 33 and 34 may be set within a range of one octave above and below the frequency at which the vibration acceleration level of the mounting panel 20 becomes maximum between 50 Hz and 3000 Hz. Further, the resonance frequency of the dynamic vibration absorbers 33 and 34 may be matched with the frequency at which the vibration of the mounting panel 20 should be attenuated in sound quality between 50 Hz and 3000 Hz, or the resonance frequency of the dynamic vibration absorbers 33 and 34 may be It may be set within a range of one octave above and below the frequency to be attenuated for sound quality. In this case, the frequency may be one octave or more away from the frequency at which the vibration acceleration level of the mounting panel 20 is highest.
[0033]
Further, the resonance frequency of the dynamic vibration absorber 34 may be set to a frequency different from the resonance frequency of the dynamic vibration absorber 33.
[0034]
The spring portions 33a and 34a of the dynamic vibration absorbers 33 and 34 are desirably formed of a material having a larger loss tangent than the mounting panel 20, the frame 1, or the magnetic circuit 2. Further, the spring portions 33a and 34a may be damped with a material having a larger loss tangent than the mounting panel 20, the frame 1, or the magnetic circuit 2.
[0035]
Since the characteristics of the speaker device 200 when actually reproduced in the vehicle become a problem, the resonance of the dynamic vibration absorbers 33 and 34 is determined based on the vibration acceleration level of the mounting panel 20 with the door mounted on the vehicle. It is preferable to set the frequency.
[0036]
As described above, in the present embodiment, the dynamic vibration absorbers 33 and 34 are mounted on the mounting panel 20 and the resonance frequency thereof is set to a predetermined frequency, so that the vibration of the mounting panel 20 can be effectively suppressed. For this reason, it is possible to suppress disturbance of the frequency characteristics and the like due to the vibration of the mounting panel 20, and it is possible to improve the acoustic characteristics of the speaker device 200.
[0037]
In the second embodiment, an example is shown in which two dynamic vibration absorbers are used, but the number of dynamic vibration absorbers is not limited to this, and may be any number of one or three or more.
[0038]
-Third embodiment-
Hereinafter, a third embodiment in which the speaker device according to the present invention is applied to an in-vehicle speaker device will be described with reference to FIGS. FIG. 6 is a plan view showing the speaker device of the third embodiment, and FIG. 7 is a cross-sectional view showing the speaker device of the third embodiment. 6 and 7, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.
[0039]
As shown in FIGS. 6 and 7, the dynamic speaker unit 10 constituting the speaker device 300 of the third embodiment is fastened to the mounting panel 20 via the frame 1.
[0040]
As shown in FIGS. 6 and 7, a plurality of (six in FIG. 6) dynamic vibration absorbers 35 are mounted on the back side (the right side in FIG. 7) of the mounting panel 20. Each dynamic vibration absorber 35 includes a spring portion 35a having one end attached to the panel 20, and a weight portion 35b attached to the other end of the spring portion 35a. The resonance frequency of each dynamic vibration absorber 35 is determined by the compliance of the spring portion 35a and the mass of the weight portion 35b in each dynamic vibration absorber 35. Each dynamic vibration absorber 35 has a function of controlling the vibration of the panel 20 and improving the acoustic characteristics.
[0041]
In the present embodiment, by attaching a plurality of dynamic vibration absorbers 35, vibration at each part of the panel 20 can be reduced, and the vibration acceleration level of the mounting panel 20 can be greatly suppressed. The resonance frequency of the dynamic vibration absorber 35 may be set in order from 50 Hz to 3000 Hz in accordance with the frequency at which the vibration acceleration level of the mounting panel 20 is large. In this case, it is desirable that the attachment site of each dynamic vibration absorber 35 be set to a site where the vibration acceleration level at the corresponding frequency is large.
[0042]
The resonance frequency of the dynamic vibration absorber 35 may be set in order between 50 Hz and 3000 Hz according to the frequency at which the vibration of the mounting panel 20 should be attenuated in terms of sound quality. In this case, it is desirable that the attachment site of each dynamic vibration absorber 35 be set to a site where the vibration acceleration level at the corresponding frequency is large. In this case, the resonance frequency of the dynamic vibration absorber 35 does not necessarily need to be set corresponding to the frequency at which the vibration acceleration level is large.
[0043]
Specifically, the resonance frequency of each dynamic vibration absorber 35 may be matched with the frequency (for example, about 1 kHz) at which the vibration acceleration level of the mounting panel 20 becomes maximum between 50 Hz and 3000 Hz. Further, the resonance frequency of each dynamic vibration absorber 35 may be set within a range of one octave above and below the frequency at which the vibration acceleration level of the mounting panel 20 becomes maximum between 50 Hz and 3000 Hz. Further, the resonance frequency of each dynamic vibration absorber 35 may be matched with the frequency at which the vibration of the mounting panel 20 should be attenuated in terms of sound quality between 50 Hz and 3000 Hz. Further, the resonance frequency of each dynamic vibration absorber 35 may be set within a range of 50 Hz to 3000 Hz within one octave above and below the frequency at which the vibration of the mounting panel 20 should be attenuated in terms of sound quality.
[0044]
The spring portion 35a of the dynamic vibration absorber 35 is desirably formed of a material having a larger loss tangent than the mounting panel 20, the frame 1, or the magnetic circuit 2. Further, the spring portion 35a may be damped with a material having a larger loss tangent than the mounting panel 20, the frame 1, or the magnetic circuit 2.
[0045]
Since the characteristics of the speaker device 300 when actually reproduced in the vehicle become a problem, the resonance frequency of the dynamic vibration absorber 35 is determined based on the vibration acceleration level of the mounting panel 20 with the door mounted on the vehicle. It is preferable to set.
[0046]
As described above, in the present embodiment, since the plurality of dynamic vibration absorbers 35 are mounted on the mounting panel 20 and the resonance frequency thereof is set to a predetermined frequency, the vibration of the mounting panel 20 can be effectively suppressed. For this reason, it is possible to suppress disturbance of the frequency characteristics and the like due to the vibration of the mounting panel 20, and it is possible to improve the acoustic characteristics of the speaker device 200.
[0047]
Note that, in the third embodiment, an example is shown in which six dynamic vibration absorbers are used, but the number of dynamic vibration absorbers is not limited to this.
