Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
The utility model discloses a kind of coaxial linear array speakers, as shown in Figure 1-Figure 3, including cabinet 1, waveguide 40 and
Same axle unit 10 in cabinet 1, with newel 13 is equipped in axle unit 10, the sound source end of newel 13 and waveguide 40 can
Releasably connect.
Connection component 50, connection component 50 are removably mounted on the opposite face of cabinet 1, by multiple cabinets 1 connection and
It is arranged in linear array.Cabinet 1 is arranged in linear array, while guaranteeing sound quality result of broadcast, it is possible to reduce the occupied area of speaker.
Multiple cabinets 1 are detachably connected by connection component 50, are rapidly dismantled and are assembled convenient for cabinet 1.
As shown in figure 3, including washer 11, magnet steel 14, T iron plate 12, newel 13, positioning ring 15, throat taps with axle unit 10
16, frame 18, vibrating diaphragm 17, voice coil 19, copper cap, terminal 23, lead, dust cap, flanging, sound membrane module 21, ring 22 and bullet
Wave, wherein washer 11, magnet steel 14, T iron plate 12, newel 13, copper cap, positioning ring 15 and throat taps 16 form high bass and share magnetic
Road, frame 18, terminal 23, drum paper, lead, voice coil 19, bullet wave, dust cap, flanging are assembled into semi-finished product unit external member, unit set
Part, magnetic circuit, rear cover 24 and 21 groups of sound membrane module are combined into coaxial unit 10.T iron plate 12, newel 13, magnet steel 14, voice coil 19
The dynamical system of same axle unit 10 is collectively constituted with washer 11, plays wave and vibrating diaphragm 17 forms vibrational system, vibrating diaphragm 17 is fixed on
In frame 18, frame 18 is used as support system.Each component with axle unit 10 is pasted by AB glue water.With the work of axle unit 10
Principle: when AC audio electric current passes through voice coil 19, voice coil 19 generates magnetic field, this magnetic field and the high bass with axle unit 10 are total
Interaction force is generated with magnetic circuit, this power just makes voice coil 19 in the magnetic field that the high bass of same axle unit 10 shares magnetic circuit with sound
The vibration of frequency current signal size is got up, and is connected together with the vibrating diaphragm 17 of vibrational system in axle unit 10 and voice coil 19, sound
Circle 19 drives vibrating diaphragm 17 to vibrate, and the vibration of vibrating diaphragm 17 produces sound identical with former audio signal waveform.
Traditional " coaxial sound box " has independent tweeter and woofer drivers respectively, and tweeter is put
It sets at the center of vibrating diaphragm 17, is overlapped the acoustic centres of high pitch generally with the acoustic centres of bass, it is this " coaxial sound box "
Tweeter and its axle center of woofer drivers be to be overlapped, but the vibrating diaphragm of tweeter and woofer drivers
Face be it is separated, therefore the high pitch acoustic centres of " coaxial sound box " and bass acoustic center can not be completely coincident, to occur
Phase deviation influences the fidelity of phase.The tweeter and woofer drivers of this " coaxial sound box " use front and back
Separated structure, there is interval between tweeter and woofer drivers, increase the width and volume of cabinet.
The coaxial sound box Hi-Mid part of this programme and bass part share washer 11, T iron plate 12, newel 13, positioning
Not only axle center is overlapped for ring 15 and magnet steel 14, treble portion and bass part, but also vibrating diaphragm face is also to be overlapped, bass and high pitch
Distortion it is smaller.Treble portion is overlapped with the vibrating diaphragm face of bass part, and physical positioning is close to point sound source, with axle unit 10
Audio is generated by point sound source, the high audio and bass synchronous transmission that point sound source generates, to keep high audio synchronous with bass
The ear for reaching listener, improves the reduction effect of acoustic image.It is " coaxial compared to traditional while correctly reduction acoustic image
Speaker ", the coaxial sound box of this programme eliminate the interval between treble portion and bass part, the limited compression body of cabinet
Product, the box volume of this structure is smaller, easily portable.
, can be by the size compression of speaker to ten inches according to the structure setting of above-mentioned treble portion and bass part, body
Product is small, easy to carry.The sound wave that traditional linear array speaker, upper speaker and lower speaker issue, which can generate, to be interfered, so that
Audio distortions, therefore this programme is equipped with waveguide 40 at the sound source end of newel 13.40 pairs of high basses of waveguide compress,
So that the compressed height change of tune, at line source, therefore, the high bass issued from linear array speaker would not interfere, simultaneously
Since line source decaying can be slower than point sound source, projection distance is farther.The linear array speaker of this programme, the range of sound are enough
Far, acoustic pressure is sufficiently large, is suitable for stage or outdoor large is performed.
It is coaxially disposed with axle unit 10 and frame 18, i.e., is overlapped, can subtract with the axis of frame 18 with the axis of axle unit 10
The phase difference of few each frequency of sound wave, to reduce the linear distortion of audio signal, to improve playing quality, acquisition is preferably listened
Sense.
