音箱维修保养
①避免放置于阳光直接暴晒的场所,不要靠近热辐射器具,如火炉、暖气管等,也不要放置于潮湿的地方。
②音箱在连接到放大器之前,应先切断放大器的电源,以免损坏扬声器。
③与放大器的馈线连接应稳妥,在受到拉拽时不能掉下,正负极性不能接错。连接扬声器的馈线要足够粗,不宜过长,以免造成损耗和使阻尼变坏。以偏离频率响应最大值士0.5dB(0.75mm2导线最大长度9cm,1.5mm2导线最大长度14m,2.0mm2导线最大长度21m。
④应注意扬声器的阻抗是否适合放大器的推荐值。
⑤不得超出额定功率使用。否则音质会变坏,甚至损坏扬声器。
⑥外壳应该用柔软、干燥的棉布擦拭,不要涂家具蜡或苯、醇类物质。
⑦扬声器表面的尘埃只能用软毛刷清除,不能用吸尘器吸除。
⑧音箱要放在坚固、结实的地板上,以免低音衰减。音箱不要太靠近墙壁放置。
⑨不要将音箱放置得太靠近电唱盘,以免产生声反馈造成啸叫。
⑩如设有中、高音电平调整,可按听着要求调整到使放声满意。
好的音箱决不仅仅是声音重放效果良好。它更重要的功能是,把音乐以及电影音乐中所有的能量和热情全部传递给你,让你的心灵激荡,让你能充分体验和感受那听乐的欢乐!就应当去买这样的一对音箱!
Speaker repair and maintenance
① direct exposure to sunlight to avoid placing the place, not near the thermal
radiation equipment, such as stoves, heating pipes and so on, do not put in moist
places.
② speakers connected to the amplifier before you cut off the power amplifier,
so as not to damage the speakers.
③ feeder connection with the amplifier should be safe, pull in the subject
could not be dropped, can not take the wrong polarity. Connect the speakers
to be sufficiently coarse feeder, not long, so as to avoid loss and deterioration
to damping. Disabilities to the maximum frequency response deviation 0.5dB
(0.75mm2 wire maximum length 9cm, 1.5mm2 wire maximum length 14m, 2.0mm2 wire
maximum length 21m.
④ should pay attention to whether the speaker's impedance amplifier for the
recommended values.
⑤ not exceed the rated power use. Otherwise, sound quality will deteriorate,
or even damage the speaker.
⑥ shell should be soft, dry cotton cloth, not painted furniture wax or benzene,
alcohols.
⑦ speaker's surface with a soft brush can remove dust, can not use vacuum
cleaner sucked.
⑧ speaker to put strong, solid floor to prevent bass attenuation. Speaker not
to place too close to the wall.
⑨ Do not place the speakers too close to the turntable, in order to avoid
acoustic feedback caused by howling.
⑩ as set in , treble level adjustment, can be adjusted to the required listening
to burst satisfaction. good sound reproducing speaker must not only good results.
It is more important feature is that the music and film music in all the energy
and enthusiasm all pass to you, let your soul stirring, so you can fully
experience and feel that listening to music of joy! should buy such a pair of
speakers!
音箱和音响区别:
通常两者有概念和实用上的区别:
第一:整体与部分的区别.就是音响是一整套系统,而音箱只是这个系统中的一部分.是属于发声设备,系统还包括其他混音等设备.
第二:专业与业余的区别.两者都是也都可以发出声音.但音响从功能上到配置上都属于专业级别的发声系统.而音箱就是通常俗指由一个或两个普通的音箱构成的一个简单的发声系统.就好比家庭影院就可以称为音响,而电脑音箱因为功能简单,效果较低,就通常只称为音箱.
Speakers and sound difference: usually the difference between the concepts
and practical distinctions: First: the difference between whole and part.
That is a set of audio systems, speakers just a part of this system. Are sound
equipment, the system also includes other mixing equipment. Second: the
distinction between professional and amateur. both of which are also a voice.
But the audio from the functional to the configuration are all professional-level voice system. The speaker is usually a popular means or two ordinary
speakers consisting of a simple sound system.'s like to be known as the home
theater audio, and computer speakers because the functions are simple and
relatively low, it is usually referred to as speaker.

Equalizer——均衡器,用于调整频率的补偿和衰减;简称: EQ
Bass——低频(通常提升或衰减100Hz附近频段的声音)
Middle——中频(通常提升或衰减500-2000Hz附近频段的声音)
Treble——高频(通常提升10000Hz附近频段的声音)
Tone Shift——音色转换;
Overdrive——过载;
Gain——增益;
Overdrive Contour——过载等高线;
Level——电平;
Power Dimension——电源度数;
Reverb——混响;
Line Out——线路输出;

Fuse——保险丝 。
选购技巧
对于一对音箱的最初了解,可用“观、掂、敲、认”的步骤来鉴别:即一观工艺,二掂重量、三敲箱体、四认铭牌。
一观工艺就是从音箱外表的第一部象来判断该次和品质优劣:用天然原木精工打造的音箱当然最好,许多天价级的世界名牌至尊音箱,故常见的音箱均是以MDF中密度纤维板表面敷以一层薄薄的木皮做装饰:敷真木皮精工外饰的音箱,尤其是如酸枝、雀眼、花梨、胡桃、桢楠、红橡等珍稀木皮,其天然木纹视觉效果极好,手感滑腻舒适。尤其以对称蝴蝶花纹真木皮经多层涂复打磨钢琴亮漆者,大多均可视为中高档精品音箱,仿冒品极少。用PVC(沙比利)塑料贴皮的箱子属大路货,虽做工精细,最好也只能算中低档货色。而以本纹纸贴面装饰的箱子虽然看上去极时应多注意箱体背后的贴皮接缝和喇叭安装位挖扎工艺是否精确到位。假冒伪劣产品一般都不会注意这些细节,因而稍加用心即可正确判断。
二是掂重量:好的音箱大多是以18~25mm的优质MDF粒子板打造、高档旗舰级音箱则是以紫檀、黄柚之类的超重实木或多层复合胶合板来打造,所以重量非常惊人。往往一对音箱净重就达五六十公斤。中低档大路货多半采用质地松软的刨花板,仿冒伪劣产品更采用质量低劣的纸胶板,故重量一般较轻。音响界常有“内行看质量、外行掂重量”之说,重的音箱肯定比轻的音箱要好些。但要警惕不良商家在音体底部灌沙石水泥增重以欺骗消费者。
三是敲箱体:用指节敲击箱体上下左右前后障板,箱体各面均发出沉实而轻微的脆响,感觉板材质地坚硬厚实、内部有多根加强筋支撑,箱体结构合理、结实,有多种隔音和防驻波的措施等效果。该种箱体加工成本高、难度大,因而很少有假冒伪劣产品。如用指节敲击箱体发出“噗、噗”的空响,说明板材太薄,材质质量太差,结构不合理。且内部没有吸音材料或加强筋维系,从而导致箱体内有大量漫反射和驻波形成。选购这种音箱,绝不可能获得好的重放效果。
