Description

【Technical Field】 【0001】 The present invention relates to an instrument panel of a vehicle, and more particularly to a speaker system disposed on the instrument panel of the vehicle. 【Background Art】 【0002】 As a speaker system of an in-vehicle audio device, there are cases where full-range speaker units are arranged on the left and right door trims. In the case of such a speaker unit, it is necessary to lay a harness from the audio unit or the navigation system arranged in the center console part in the center of the instrument panel to the inside of the door. In addition, since it is far from the ears of the passengers, there are problems with the high-frequency sound quality. 【0003】 Therefore, there are also cases where the speaker system is separated and low-frequency speaker units are arranged on the left and right door trims, and high-frequency speaker units are arranged on the instrument panel and the left and right front pillar parts. However, in addition to the need to lay a harness to the inside of the door as described above, since the harness branches toward each speaker unit, there is a problem of increased cost. 【0004】 Further, Patent Document 1 shows a form in which speaker units are arranged at the lower part of the instrument panel and the steering wheel. However, although the speaker units are arranged relatively close to each other, they require a harness wiring cost. In addition, since the steering wheel rotates, sound image localization control according to the rotation angle is required, and there are concerns about the complication of control and the accompanying adverse effect on sound quality. 【Prior Art Documents】 【Patent Documents】 【0005】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2019-51909 【Summary of the Invention】 [Problems that the invention aims to solve] 【0006】 On the other hand, in vehicles equipped with a car navigation system, the control screen for the in-car audio system is sometimes integrated into the navigation system screen and mounted on the center console as a touch-panel center display. In addition to these, there is also consideration being given to integrating the speedometer function into the center display. 【0007】 In that case, surplus space is created in front of the driver's seat where the speedometer was conventionally located. We realized that by utilizing this space, it would be possible to construct a speaker system that provides good sound localization and is advantageous for wiring harness routing, which led us to the present invention. 【0008】 In other words, the present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide an instrument panel equipped with a speaker system that is advantageous in optimizing sound image localization with respect to the driver's seat and reducing harness routing costs. [Means for solving the problem] 【0009】 To solve the above problems, the present invention provides The instrument panel of a vehicle, A GUI display with a meter display function including speed display, a car navigation system operation function and display function, A pair (left and right) A speaker unit for mid-to-high frequencies and a woofer unit for low frequencies, The first enclosure of the mid-to-high frequency speaker unit and the second enclosure of the low-frequency woofer unit It includes a speaker system including an enclosure, The GUI display is located in the central area of ​​the instrument panel. The speaker unit is positioned in the upper right or upper left region of the instrument panel, facing the driver's seat. The aforementioned 1The enclosure is positioned in the upper right or upper left region so as to surround the speaker unit from behind the GUI display inside the instrument panel. The woofer unit is located behind the GUI display. 1 It is located on the vehicle's instrument panel, which is positioned at the top of the enclosure. [Effects of the Invention] 【0010】 As described above, the instrument panel according to the present invention allows for the symmetrical placement of mid-to-high frequency speaker units in front of the driver's seat where the speedometer was conventionally located, enabling the configuration of a speaker system that provides good sound image localization and is advantageous for wiring harness routing. [Brief explanation of the drawing] 【0011】 [Figure 1] This is a perspective view showing an instrument panel according to an embodiment of the present invention. [Figure 2] This is a front view showing an instrument panel according to an embodiment of the present invention. [Figure 3] This is a cross-sectional view of XX in Figure 2. [Figure 4] This is a schematic front view showing the GUI display. [Modes for carrying out the invention] 【0012】 Embodiments of the present invention will be described in detail below with reference to the drawings. In Figures 1 and 2, the instrument panel 1 according to the embodiment of the present invention has a GUI display 2 positioned at the top of the central area (center console), and speaker units 31, 31 constituting the speaker system 3 are arranged in the upper right area facing the driver's seat. 【0013】 The GUI display 2 is a thin touch panel type display. As shown in FIG. 4, the display surface includes a meter display 21 including a vehicle speed display, a display and operation unit 22 of a car navigation device, and a display and operation unit 23 of an air conditioning system 4. 【0014】 In the illustrated example, the display area is divided into three parts vertically and displayed simultaneously. By adopting a multi-window system, any one of them can be switched to full-screen display or enlarged display and the others can be switched to reduced display. In addition to the above, it also has a function as a display and operation unit of a sound system (audio system). 【0015】 The speaker system 3 includes mid-high range speaker units 31, 31 and a woofer unit 32 for the low range. The mid-high range speaker units 31, 31 are composed of two speaker units symmetrically arranged at positions facing the driver's seat on the front surface (baffle) of the upper enclosure 30, and can reproduce the sound image localization of stereo sound sources well. The lower enclosure 33 is provided as an extended enclosure for the speaker units 31, 31, and can also form left and right back-loaded horns inside. 【0016】 As shown in FIG. 3, the woofer unit 32 for the low range is arranged above the base 43 of the air duct 44 of the air conditioning system 4. That is, the air duct 44 of the air conditioning system 4 extends straight upward from the upper part of the air conditioning unit 40, extends obliquely toward the passenger compartment 10 side above the lower enclosure 33, and branches into left and right air ducts 44. It is provided so as to penetrate the lower surface wall of the widened part immediately before this branch. 【0017】 The air duct 44(43) is reinforced by a reinforcing frame (not shown here), giving it rigidity, and the woofer unit 32 is attached to this reinforcing frame. With this structure, the entire Y-shaped air duct 44(43) that communicates with the air outlets 41 on both sides of the GUI display 2 functions as an enclosure for the woofer unit 32. 【0018】 Note that the air ducts 45 that communicate with the air outlets 42 on the left and right sides of the instrument panel 1 branch left and right from the upper part of the air conditioning unit 40. Also, as shown in FIG. 3, a defroster air duct 47 is provided on the front F side in the vehicle front-rear direction of the air duct 44(43). 【0019】 As shown in FIG. 3, the woofer unit 32 is arranged obliquely spaced apart from the back of the thin panel-shaped GUI display 2, so an excess space is formed between the back of the GUI display 2 and the woofer unit 32, and the enclosure of the woofer unit 32 can also be formed in this space. 【0020】 Also, the lower enclosure 33 can be used as the enclosure of the woofer unit 32. In that case, by integrating or sub-assembling the left and right speaker units 31, 31 and the enclosures 30, 33 of the woofer unit 32, the assembly to the instrument panel 1 becomes easier. 【0021】 The woofer unit 32 is preferably arranged so as to at least partially overlap with the mid-high range speaker unit 31 in the vehicle height direction H. The low-range woofer unit 32 does not affect sound image localization, but by arranging it in the lateral direction of the mid-high range speaker unit 31, the length of the harness can be shortened and the harness wiring cost can be reduced. 【0022】 Furthermore, as shown in Figure 2, it is preferable that the woofer unit 32 is positioned offset towards the speaker unit 31 with respect to the center (c) in the vehicle width direction of the GUI display 2. By positioning the woofer unit 32 towards the speaker unit 31, the length of the harness can be further shortened, and the cost of routing the harness can be reduced even further. 【0023】 As described above, in the instrument panel 1 according to the embodiment of the present invention, the GUI display 2 is disposed in the central area of ​​the instrument panel 1, the speaker unit 31 is positioned in the upper right or upper left area of ​​the instrument panel 1 facing the driver's seat, the enclosures 30 and 33 are disposed in the upper right or upper left area of ​​the instrument panel 1 so as to surround the back of the speaker unit 31 from behind the GUI display 2, and the woofer unit 32 is disposed on top of the enclosures 30 and 31 behind the GUI display 2. By utilizing the space behind the thin GUI display 2 to position the enclosures 30 and 33, it is possible to enlarge the enclosures 30 and 33 and improve sound quality. 【0024】 Furthermore, the woofer unit 32 can be installed in the space behind the GUI display 2, which allows for good layout flexibility in the rear space and is advantageous for improving bass sound quality. 【0025】 The woofer unit 32 is positioned on top of the enclosures 30 and 31, but is hidden behind the tall GUI display 2, thus maintaining an aesthetically pleasing appearance. Furthermore, since the woofer unit 32 is assigned to low frequencies, even if it is positioned behind the GUI display 2, the sound will not wrap around, thus suppressing any degradation in sound quality. 【0026】 In addition, since the woofer unit 32 is positioned so that at least a portion of it overlaps with the speaker unit 31 in the vehicle's height direction, placing the woofer unit 32 parallel to the speaker unit 31 and then placing it next to the speaker unit 31 can improve the sound quality of the woofer unit 32. 【0027】 The speaker unit 31 for the mid-to-high frequencies is better positioned closer to ear level and is located at the top of the instrument panel 1, which improves sound quality. In this case, the position of the woofer unit 32 becomes higher, but because the GUI display 2 is also high, the sound quality can be improved without negatively impacting the appearance. 【0028】 Furthermore, since the woofer unit 32 is positioned on the flat surface of the instrument panel 1, offset from the center of the GUI display 2 in the vehicle width direction, towards the speaker unit 31, the woofer unit 32 can be positioned behind the GUI display 2, hidden from the front view of the GUI display 2, and close to the side of the speaker unit 31. This allows the distance between the woofer unit 32 and the speaker unit 31 to be reduced as much as possible. In other words, the sound quality can be improved by reducing the phase difference with the speaker unit 31. And by positioning the woofer unit 32 on a flat surface, the sound quality can be improved. 【0029】 Furthermore, the woofer unit 32 is positioned at an angle away from the back of the GUI display 2, which allows it to partially reflect and diffuse sound off the GUI display 2, thereby improving the sound quality inside the vehicle. 【0030】 Furthermore, air ducts 43, 44, and 45 are provided inside the instrument panel 1 to supply conditioned air to air vents that open towards the passenger compartment 10. The woofer unit 32 is positioned on the walls of the air ducts 43, 44, and 45, using the air ducts 43, 44, and 45 as its enclosure. Because the air ducts 43, 44, and 45 are directed towards the driver's seat, the phase of the sound from the speaker unit 31 can be inverted, which can enhance the resonance, especially in the low frequencies. 【0031】 Although several embodiments of the present invention have been described above, it should be noted that the present invention is not limited to the above embodiments, and various further modifications and changes are possible based on the technical concept of the present invention.
