[0002] 这种扬声器通常制造成基本上方形的盒子,它具有面向收听者的前壁,在该前壁上装配有一个或多个作为声变换器的扬声器架。 [0002] Such a loudspeaker is generally manufactured as a substantially square box having a front wall facing the listener, one or more acoustic transducer as a speaker in the front wall of the frame assembly. 扬声器架在此装配在前壁上或齐平地装配到其中,这是因为声音应该尽可能自由地发射到空间中。 In this assembly the speaker frame on the front wall or flush fitted therein, which should be as freely because the sound is emitted to the space. 这种扬声器通常具有较高的失真或畸变系数,这有害于放声。 Such speakers generally have higher distortion or aberration coefficient, which is harmful to burst. 此外由于开放的设置结构而存在损伤机械敏感的扬声器架的危险,人们通常利用遮盖材料或类似物来试图应付该危险。 Furthermore, since the open configuration provided there is a risk of mechanical damage to the sensitive speaker frame, people usually use masking material or the like in an attempt to deal with this risk. 一方面这些措施通常仅仅实现不充分的机械保护,另一方面安置在扬声器壳体上的遮盖物框架导致干扰的啪嗒啪嗒声。 These are usually implemented on the one hand measures only insufficient mechanical protection, on the other hand is disposed on the speaker housing covering frame cause rattling sound interference.

[0003] 此外传统扬声器箱的由木材或类似木材的材料如中密度纤维板(MDF)制成的壳体不足以隔音,这意味着尽管具有内部加固件,也由壳体壁发射出失真的次级声音的声响。 [0003] Also of wood or wood-like material such as a conventional loudspeaker enclosures medium density fiberboard (MDF) housing made insufficient insulation, which means that despite having an internal reinforcement, but also emits secondary distortion by the housing wall sound level of the sound. 由EP 0191595 B1已知扬声器壳体的一种蜂窝状加固件,它应应对这个问题,但是在实际情况中并不完全解决。 One kind of honeycomb reinforcing member is known from EP 0191595 B1 speaker housing, which should deal with this, but does not fully address the situation.

[0004] 最后需要指出的是:由中音放音单元和低音放音单元产生的声波与它们在相应的膜上的发射位置相关地互相影响,这同样导致声音失真。 [0004] Finally, it should be pointed out that: Central bass sound playback unit and the acoustic sound generating unit of the discharge in relation to interact with their respective positions in the transmission film, which also result in distorted sound.

实用新型内容 SUMMARY

[0005] 由此出发本实用新型的目的在于:提供一种文首述及类型的扬声器,它能够实现尽可能无失真的放声。 [0005] Proceeding from the present invention aims to: provide a first type of speaker mentioned article, it can achieve as much as possible without distortion aloud.

[0006] 为了实现这个目的提出一种扬声器,其具有壳体和设置在该壳体中的至少一个声变换器,其特征在于:设有多个构造在壳体中的彼此分离地延伸的用于由所述至少一个声变换器的前侧和/或后侧产生的声波的通道。 [0006] To achieve this object to provide a speaker having a housing and at least one acoustic transducer disposed in the housing, characterized in that: in a configuration provided with a plurality of housing extending separately from each other the channel generated by the front side of the at least one acoustic transducer and / or the rear sound waves.

[0007] 本实用新型主要从以下认识出发,S卩,在中音扬声器开放式地发射声音时,出现由扬声器膜的不同位置产生的声波的相互影响、即声音失真。 [0007] The present invention mainly starting from the recognition that, S Jie, when open squawker transmit sound generated by the interaction occurs at different positions of the acoustic loudspeaker membrane, i.e., sound distortion. 根据本实用新型因此提出:设置有多个构造在壳体中的彼此分离地延伸的用于由至少一个声变换器的前侧和/或背侧产生的声波的通道。 The present invention therefore proposes: a plurality of configuration provided in the housing for generating from the front side of the at least one acoustic transducer and / or sound waves back side extend separately from one another channel. 由此实现本实用新型的有益效果:避免由膜的一个位置发射的声波在另一个位置上的反作用,由此减小扬声器的失真。 Thereby achieving the advantages of the present invention: to avoid the sound waves emitted by the reaction of a position of the film at another location, thereby reducing distortion of the speaker.

[0008] 在本实用新型的有利的设计中,至少一个声变换器设置在壳体的前壁的后面,该前壁具有多个声音通孔。 [0008] In the present novel advantageous practical design, the at least one acoustic transducer disposed behind the front wall of the housing, the front wall having a plurality of the sound through-holes. 壳体的前壁由此构成用于声变换器的保护装置,从而不需要额外的保护元件。 The front wall of the housing thereby constituting protection for acoustic transducer means, so that no additional protective element. 适宜地,声音通孔构造成彼此分离的通道并且各自具有的宽度小于由至少一个声变换器产生的最高频率的波长的一半。 Suitably, the sound through-hole is configured to separate from each other and each channel having a width smaller than half the wavelength of the highest frequency is generated by at least one acoustic transducer. 宽度的概念在本文中被视为与扬声器在空间中的工作布局有关。 The width of the concept in this paper is considered to work with the speaker layout in space-related. 声音沿水平方向的传播比沿竖直方向的传播更重要。 Sound propagation in a horizontal direction of propagation is more important than the vertical direction. 所提及的声音通孔在宽度上的尺寸限制防止孔内部的声波共振。 Mentioned sound via size in width restriction prevents acoustic resonance inside the hole. 这还通过如下措施得到支持,即,通道在本实用新型的优选的设计中基本上垂直于前壁的平面延伸并且构造成向着前壁的背侧的方向锥形渐缩的长形孔。 This is also supported by the following measures, i.e., the channel and configured to extend substantially in the direction of the back side of the front wall of the conically tapering elongated hole in design of the present invention is preferably perpendicular to the plane of the front wall. 为了覆盖宽的频率范围有利的是,设置两个声变换器,其中的第一声变换器构造成中音放音单兀或低中音放音单兀、优选动态的锥形扬声器,而第二声变换器构造成高音放音单兀、优选环形号角扬声器。 In order to cover a wide frequency range is advantageously provided two acoustic transducer, wherein the first acoustic transducer configured to playback single midrange or low tenor Wu Wu playback single, preferably a dynamic cone speaker, and the first two tweeter transducer configured to playback single Wu, preferably annular horn speaker. 当低音区由一个单独的低音扬声器模块放出时,扬声器的壳体可以紧凑地设计。 When discharged by a separate bass subwoofer module, the speaker housing can be compactly designed. 这种具有两个紧凑的元件/高音扬声器和单独的低音模块的结构设计通常作为卫星系统而已知。 Such a compact design having two elements / tweeter and a separate bass module typically known as a satellite system.

[0009] 在本实用新型的另外的特别有利的设计中,设置在中音放音单元之前的通道具有如下的轮廓,该轮廓在考虑中音放音单元的膜行程的情况下延伸至该膜处并且构成与该膜互补的轮廓形状。 [0009] In the present invention further particularly advantageous embodiment, the channel set before the playback unit Alto has a profile that extends to the film in consideration of the midrange sound discharge stroke of the membrane unit and the film configuration complementary to the profile shape. 中音放音单元的前侧的声音发射由此分别由中音放音单元膜的与各通道对应的表面区域来实现并且防止这样形成的膜区域的互相影响。 Front side of the midrange sound playback unit are thereby neutral sound emission surface area corresponding to each channel of the playback unit and to prevent the film to achieve mutual influence of the film thus formed region.

[0010] 为了提高中音放音的效率,壳体有利地构造成具有设置在前壁中的低音反射孔的低音反射壳体,该低音反射孔通过由彼此分离的低音反射通道构成的系统而与中音放音单元的背侧连通。 [0010] In order to improve the discharge efficiency midrange sounds, the housing is advantageously configured as a bass reflex housing having a bass reflex apertures provided in the front wall of the bass reflex apertures separated by one another by the channel configuration of the bass reflex system midrange and playback unit communicates back side. 低音反射通道有利地具有以下尺寸,即,中音放音单元的前侧和背侧的声学载荷得到补偿,这进一步减小放音的失真。 Advantageously, the bass reflex channels have the following dimensions, i.e., the front and back sides of the acoustic playback unit load midrange compensated, which further reduces distortion of the playback. 此外在低音反射通道中应不产生涡流的流动和/或流动反射。 It should also be no flow and / or flow vortices in the bass reflex reflector passage. 这些低音反射通道因此有利地如此设计,即,这些低音反射通道在壳体中的方向改变是平滑弯曲的,其中,考虑将其横截面的最小纵向延伸长度作为标准来作为方向改变的最小半径。 The bass reflex channel thus advantageously designed such that these bass reflex channel change is smoothly curved in the direction of the housing, wherein, considered in cross-section of the longitudinal extension of the minimum as a standard as to change the direction of the minimum radius. 此外在低音反射通道内不应产生声学的共振。 Furthermore should the acoustic resonance in the bass reflex channel. 所述低音反射通道因此有利地具有如下的横截面,其最大的长度尺寸小于与低音反射孔连通的声变换器的最高频率的波长的一半。 The bass reflex channel thus advantageously has a cross-section, the maximum length dimension smaller than half the wavelength of the highest frequency of the transducer and the bass port communication. 对低音反射系统的符合实际的调整规定80HZ至120Hz之间的中频。 Bass reflex system in line with the actual adjustment between the predetermined intermediate frequency 80HZ to 120Hz. 在发射200Hz至5kHz的频率时中音放音单元对低音反射通道产生激励,但是不产生空腔共振。 When the transmission frequency of 200Hz to 5kHz midrange playback unit for generating an excitation bass reflex channel, but does not produce a cavity resonator. 相反,200Hz至5kHz的频率从空间进入低音反射孔并且由于其上的小结构而在箱容积中受阻地产生共振和/或抹消。 In contrast, the frequency of 200Hz to 5kHz from entering the space and because of the small bass port structure to which the resonance and / or erased in the tank volume and unobstructed. 这有利于避免中音放音单元的不同的膜载荷。 This helps to avoid different films midrange loads playback unit.

[0011] 因为壳体应具有尽可能高的强度,并且低音反射通道的结构可以具有复杂的线路,所以壳体在本实用新型的特别有利的结构设计中由多个板状的成形件组装而成。 [0011] Since the housing should have as high a strength, and the bass reflex channel structure may have a complicated circuit, the housing in the present invention are particularly advantageous structure assembled from a plurality of plate-shaped design of the molding member to make. 各个成形件具有空隙,它们以组装的形式构成低音反射通道和壳体的其它自由空间。 Each shaped member having a gap, which constitutes the other channels and a free space bass reflex housing in assembled form. 特别地,成形件可以构造成由金属、优选由铝合金制成的铣削件或再铣削的铸件或构造成通过3D打印方法制成的主体并且互相螺纹连接、粘接或焊接。 In particular, the shaped member can be configured to re-milled or milled parts made of metal castings, preferably made of an aluminum alloy or configured by a body made of another 3D printing method and screwing, bonding or welding.

[0012] 为了在典型的收听距离上模仿声点源的理想状态,中音放音单元可以向着高音放音单元的方向倾斜0.5°至5°、优选大约2.5°地设置在壳体中。 [0012] For ideal point source of sound in imitation of a typical listening distance, midrange playback unit may be inclined 0.5 ° to 5 ° towards the discharge direction of treble sound units, preferably about 2.5 ° is provided in the housing. 当角度为2.5°时在大约2.5m的距离上达到该效果。 To achieve this effect when the angle at a distance of about 2.5m when 2.5 °.

具体实施方式 detailed description

[0017] 附图所示的扬声器具有壳体10,该壳体由多个板状的成形件12-34组装而成。 [0017] The speaker 10 shown in the drawings has a housing, the housing is assembled from a plurality of plate-shaped members 12-34 together.

[0018] 图1示出扬声器的前视图,该扬声器具有形成前壁的成形件12,在前壁的后面彼此紧邻的在中心设置有高音放音单元38,而在边缘侧设置有中音放音单元40。 [0018] Figure 1 shows a front view of a speaker, the speaker having a shaped front wall 12 is formed in the back of the front wall is provided in the center next to each other treble playback unit 38, and disposed at the edge of the discharge side Alto tweeter 40. 前壁12具有约10mm的厚度并且如其余成形件14-34那样是由招合金制成的再统削(ueberfraesen)的铸件,由此具有高的机械稳定性。 The front wall 12 has a thickness of about 10mm and the rest as above, then cut system (ueberfraesen) made of a cast alloy forming member 14-34 strokes, thereby having a high mechanical stability. 前壁由多个设置在规律的网格中的声音通孔42穿过,这些声音通孔构造成长形孔并且向着作为通道的壳体内侧的方向略微锥形地变细。 Sound front wall traversed by a plurality of through holes provided at regular grid 42, which sounds an oblong hole vias and configured inside the housing in the direction of the path as slightly conical tapers. 孔42可以具有如下的尺寸,即,其宽度小于由高音放音单元产生的最高频率的波长的一半,由此防止在水平的收听平面上形成孔42中的可觉察的共振。 Hole 42 may have a size, i.e., a width smaller than half the wavelength of the highest frequency of a tweeter generated playback unit, thereby preventing the formation of appreciable resonance apertures 42 in the horizontal plane of the listener. 与高音放音单元38镜像对称地存在低音反射通道46的多个出口44(图2),这些低音反射通道与中音放音单元40的背侧连通。 And treble playback unit 38 mirror-symmetrically to a plurality of outlet 46 bass reflex channel 44 (FIG. 2), these passages and tenor bass reflex discharge unit 40 communicates back side of the sound. 低音反射通道如此构造和设计尺寸,使得在这些低音反射通道中不会产生涡流和/或共振。 Bass reflex channel constructed and dimensioned, so that no eddy current is generated and / or resonance of these bass reflex channels. 彼此分离地延伸的低音反射通道的复杂形状能够通过壳体10的结构实现,所述壳体由带有分别彼此连接的空隙的板状的成形件12-28构成。 Bass reflex complicated shape passages extending separately from one another can be achieved by the structure of the housing 10, said housing formed of a plate shaped member with a gap of 12-28 are connected to each other.

[0019] 在前壁上连接有成形件14和16,它们在中心具有用于构造成环形号角的高音放音单元38的空隙,然而在中音放音单元40的区域中,声音通孔42通道状地并且轮廓配合地延伸至中音放音单元的锥形膜的表面附近,其中,剩余的距离几乎不大于膜行程所要求的距离。 [0019] with a shaped member connected to the front wall 14 and 16 at the center thereof an annular configuration having a horn treble sound discharge gap unit 38, while in the discharge area midrange sound unit 40, the sound through-holes 42 near the surface shape and contour of the channel extends to the mating tapered discharge midrange sound membrane unit, wherein the remaining film from a distance greater than the stroke is hardly required. 这似乎导致将中音放音单元的发射声音的面分配成在声学上不互相影响的区域,这些区域的尺寸大致与孔42相符。 This appears to result in the emission distribution midrange sound playback unit surface area not to affect each other acoustically, the size of these areas is substantially in line with the aperture 42. 如图1中可以看出的,该尺寸分别仅仅是总面积的几个百分比。 1 can be seen, the dimensions are only a few percent of the total area. 这在一定程度上导致所发射的声波的整流并减小声图的失真。 This results in the emitted acoustic wave rectified to some extent and reduce the distortion of the sound FIG.
