请参阅图 1及图 2， 所述分频器 25固定于所述 A柱 12的收容槽 121内， 其用于 将车载音响主机 21 输出的信号分离成高音、 中音及超重低音信号，然后分别送入相应 的所述高音喇叭 22、 中音喇叭 23及超重低音喇叭 24。所述功率放大器 26与所述车载 音响主机 21及分频器 25电性相连， 该功率放大器 26用于将车载音响主机 21输出的 信号放大， 然后传输至所述分频器 25。 功率放大器 26放置于所述一驾座 15的下部， 因而可减少占用空间。 由于去掉了现有的放置于汽车后方行李箱内的用于驱动重低音 喇叭的功率放大器， 因而减轻了汽车负荷， 从而节省汽车能耗及空间。  Referring to FIG. 1 and FIG. 2, the frequency divider 25 is fixed in the receiving slot 121 of the A-pillar 12 for separating the signals output by the car audio host 21 into high-pitched, mid-range and subwoofer signals, and then The corresponding tweeter 22, midrange speaker 23 and subwoofer 24 are respectively sent. The power amplifier 26 is electrically connected to the in-vehicle audio host 21 and the frequency divider 25 for amplifying the signal output from the car audio host 21 and then transmitting the signal to the frequency divider 25. The power amplifier 26 is placed at the lower portion of the driver seat 15, thereby reducing the space occupied. By eliminating the existing power amplifier for driving the subwoofer placed in the trunk of the car, the vehicle load is reduced, thereby saving energy consumption and space.
请参阅图 4， 图 4为图 1所示车载音响的中音喇叭另一种实施例的结构示意图， 其包括一圆铁 41 及依次设置在圆铁 41 一侧的一第一主磁铁 42、 一华丝 43、 一第二主磁铁 44、 一音膜 45及卡设在圆铁 4 1 两侧的固定板 46。 该 中音喇叭体积小， 因而便于设置在有限体积的 A柱上。 Please refer to FIG. 4. FIG. 4 is a schematic structural diagram of another embodiment of the mid-range speaker of the car audio system shown in FIG. The utility model comprises a round iron 41, a first main magnet 42 arranged on one side of the round iron 41, a huahua 43, a second main magnet 44, a sound film 45 and two sides of the round iron 4 1 . Fixing plate 46. The midrange speaker is small in size and thus easy to set on a finite volume A-pillar.
本实用新型车载音响由于各部件均装设于汽车的前部， 因而可节省相关连接线， 从而可节约成本。 由于汽车 A柱 12便于拆装， 因而现有的汽车需安装本实用新型车 载音响时， 仅通过原车的 A柱 12外形和尺寸开模， 然后将中音喇叭 23及高音喇叭 22 安装至 A柱 12上即可， 因而不仅便于车载音响的改装及升级， 而且节省时间、 效率 高， 从而可降低成本。 在本实施例中， 改装一车载音响仅需 1小时。  Since the vehicle audio of the utility model is installed at the front part of the automobile, the related connection line can be saved, thereby saving cost. Since the automobile A-pillar 12 is easy to disassemble, when the existing automobile needs to install the vehicle-mounted audio of the utility model, only the shape and size of the A-pillar 12 of the original car are opened, and then the mid-range speaker 23 and the tweeter 22 are mounted to the A. The column 12 can be used, which not only facilitates the modification and upgrade of the car audio, but also saves time and efficiency, thereby reducing the cost. In this embodiment, it takes only one hour to retrofit a car audio.
综上所述， 本实用新型车载音响通过将高音喇叭 22及中音喇叭 23安装于汽车的 A柱 12上， 超重低音喇叭 24安装于前车门 14内侧， 因而声场定位恰当， 从而中音和 高音在传播时不会造成相交频段的相位失真， 此外， 声音在传播过程中以直达声为主， 因而声音不仅细腻、 丰满， 而且清晰及层次感好。  In summary, the vehicle-mounted audio of the present invention mounts the tweeter 22 and the mid-range speaker 23 on the A-pillar 12 of the automobile, and the subwoofer 24 is mounted inside the front door 14, so that the sound field is properly positioned, thereby making the middle and high-pitched sounds. In the process of propagation, the phase distortion of the intersecting frequency band is not caused. In addition, the sound is mainly direct sound during the propagation process, so the sound is not only delicate, full, but also clear and layered.
