Abstract
The embodiment of the utility model discloses a retrofitted vehicular audio system which comprises original vehicle sound equipment which is electrically connected with a power amplifier. The power amplifier is electrically connected with a subwoofer, an audio player and a loudspeaker. The original vehicle sound equipment is electrically connected with the power amplifier through a lossless wire harness. The audio player is an MP3 player, an MP4 player, a handset or a computer. The power amplifier is a digital D-class power amplifier. The retrofitted vehicular audio system provided by the utility model has characteristics of good timbre, convenient operation and low cost.
Description
Technical field
The utility model relates to a kind of vehicle audio, relates in particular to a kind of car audio system of repacking.
Background technology
Car audio system generally all is installed in the compartment of passenger car (passenger vehicle), in order to enrich driver and conductor's culture life, to reach, enliven atmosphere in car, fatigue-relieving, make people's mood joyful. and traditional is connected to because the large sound equipment that is positioned at the automobile middle control position reaches by horn wire many loudspeaker compositions that are positioned at the automobile assigned address with the car car audio system.It is to guarantee to fully demonstrate under the prerequisite of inherent function in line with the principle design of least cost.For general-utility car, the power of its sound equipment is less, and tonequality is poor, is not suitable with many car owners and passenger and pursues new fashion and high-grade needs.Thereby many car owners want to reequip the sound system of own automobile. traditional with the car car audio system according to vehicle body price standard configuration, sound equipment and the loudspeaker of ad eundem price have been solidified in configuration according to the vehicle body price, and the wiring of having solidified sound system, the car owner does not select more flexibly, and larger difficulty is arranged and must pay larger repacking and upgrade cost while making car owner's repacking in the future or upgrading car audio system.
Traditional method of modifying of car audio system is reservation or replaces original automobile audio, increase one or more vehicle power amplifier, increase many audio signal wires that equate with the voice-grade channel number and be connected automobile audio and vehicle power amplifier, with the equal many groups horn wire of loudspeaker number, connecting power amplifier and loudspeaker again, and change all loudspeaker. there is following some deficiency in this method of modifying:
1, traditional car audio system method of modifying is because needs are laid many audio signal wires and many group horn wires, thereby when repacking must dismantle the interior trim of former car, engineering is larger, engineering time is long, the expense of engineering and material is all higher, and need professional staff just can operate, and repacking staff's quality height directly have influence on the interior trim of car and reliability and the security of repacking;
2, traditional car audio system repacking needs to adopt long audio signal wire, the quality of audio signal wire and wiring whether reasonable all has influence on the size of string to the engine noises in sound signal, and this noise is large can badly influence the effect of sound equipment;
3, traditional car audio system repacking also needs to adopt long many groups horn wire, in order to guarantee tonequality, need use thicker horn wire, thicker horn wire has not only increased cost, also increased the weight of car, if the horn wire after repacking is morely thicker than original horn wire, may need to change the structure of car, the structural change of car may have influence on the security of car.
4, the repacking of traditional car audio system all needs professional automobile repacking staff to operate, and operation is more complicated, very familiar to the circuit of automobile, has increased undoubtedly the cost of car audio system repacking.
The utility model content
Technical problem to be solved in the utility model is, a kind of car audio system of repacking is provided, and has the advantages that tonequality is good, simple to operate.
In order to solve the problems of the technologies described above, the utility model embodiment provides a kind of car audio system of repacking, comprises former car sound equipment, and described former car sound equipment is electrically connected with power amplifier; Described power amplifier is electrically connected with subwoofer, audio-frequence player device and loudspeaker.
For improvement of the technical scheme, described former car sound equipment is electrically connected to power amplifier by harmless wire harness.
For technique scheme, further improve, described audio-frequence player device is MP3, MP4, mobile phone or computer.
For technique scheme, further improve, described power amplifier is digital D class power amplifier.
Implement the utility model embodiment, have following beneficial effect:
(1) tonequality is good;
(2) simple in structure;
(3) cost is low.
The accompanying drawing explanation
Fig. 1 is the car audio system structural representation in an embodiment of repacking described in the utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the car audio system of repacking described in the utility model, comprise former car sound equipment 1, described former car sound equipment 1 is electrically connected with power amplifier 3 by harmless wire harness 6, described power amplifier 3 is electrically connected with again audio-frequence player device 4, subwoofer 5 and loudspeaker 2, and described audio-frequence player device 4 comprises MP3, MP4, mobile phone, computer etc.5 of described subwoofer have promoted acoustical quality.Generally, described loudspeaker 2 are a plurality of, lay respectively on left front, right front, left, right, left back and right back problem, make the audio equilibrium in whole car.
The car audio system of repacking described in the utility model, can can realize the repacking to the car audio system of existing automobile without the professional, be that DIY installs, simple to operate, the problems in repacking in the prior art have been avoided, and the power amplifier 3 of selecting is low-power consumption, also reduced the loss to automobile self storage battery, and then also just guaranteed the security of automobile.In installation process, owing to being the circuit that has retained former car, only need connect by the joint of harmless wire harness, thereby without automotive trim is damaged, and the power amplifier, the audio-frequence player device that with former car sound equipment, are connected are all suitable with the power of former car sound equipment, thereby just can not have influence on original circuit of automobile yet, and then just guarantee the security of automobile.The car audio system of simultaneously repacking described in the utility model, the use of subwoofer 5 and harmless wire harness 6, improved tonequality greatly, and power amplifier 3 adopts is digital D class power amplifier, facilitated the operation of car audio system.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belong to the scope that the utility model is contained.
