Description
Technical field
The utility model relates to a hammock type elastic cord suspension system and has the ribbon speaker of hammock type elastic cord suspension system.
Background technology
Traditional ring suspension system bores basin loudspeaker and Dome loudspeaker because its good performance and simple structure are widely used in for a long time.But such as, for some non-circular loud speakers, rectangle loud speaker, its application is then limited by very large.
Summary of the invention
In order to break through above-mentioned restriction, the utility model proposes a hammock type elastic cord suspension system.
It is a hammock type elastic cord suspension system that the utility model solves the technical scheme that its technical problem adopts, it is a suspension system being applied to belt vibrating membrane loudspeaker or microphone, it is characterized in that: framework is provided with the elastic wire that N bar take elastic cord as representative, such wire rod is including, but not limited to elastic cord, spandex thread, elastic thread, N is any positive integer, belt vibrating diaphragm is fixed, is suspended on elastic cord, thus belt vibrating diaphragm obtains the elastic restoring force from elastic cord in vibration processes.At traditional aluminium strip high pitch loudspeaker and printed in the planar diaphragm speaker of aluminum conductor, vibrating diaphragm is secured directly on framework, which results in these loud speakers and is difficult to playback middle pitch and bass; And in the belt vibrating membrane loudspeaker that have employed this hammock type elastic cord suspension system, the two ends of belt vibrating diaphragm are fixed respectively, be suspended on an elastic cord, this makes these loud speakers to carry out full range playback.
Oscillating component length Lr and the length Ld of vibrating diaphragm driving element on vibrating diaphragm length direction of belt vibrating diaphragm meet following relational expression: Lr > Ld+10mm.The reason arranging this relational expression is as follows: in traditional aluminium strip high pitch loudspeaker, the clamp port of aluminium belt diaphragm nestles up the plastic casing holding magnetic circuit assembly, the oscillating component length Lr=magnetic gap length Ld+2x plastic casing wall thickness of vibrating diaphragm, and plastic casing wall thickness is generally less than 5mm, i.e. Lr < Ld+10mm; A problem can be produced like this: due to vibrating diaphragm fixed port from magnetic gap termination very close to, fail to produce as the vibrating diaphragm be located in the middle part of magnetic gap good vibration owing to being subject to larger binding force near the vibrating diaphragm of fixed port, in other words, the magnetic field at magnetic gap two ends does not obtain good utilization; Traditional planar diaphragm speaker having printed aluminum conductor and electrostatic loudspeaker also have same problem; For this reason, the utility model proposes following solution: the length lengthening belt vibrating diaphragm, is embodied as: Lr > Ld+10mm.
The elastic restoring force that elastic cord provides for belt vibrating diaphragm also can be provided by following belt diaphragm tensile force sheet: this tension piece is a syllogic tension piece, be made up of elastomeric material, its interlude is that a cross section is broken line, circular arc, straight line or other be suitable for the cylinder of curve, respectively there is a plane at its two ends, left and right, one of them plane is bonding with the termination of vibrating diaphragm, and another plane is then bonded on framework with level or vertical mode; The interlude of this tension piece can be shaped at the two ends direct pressing of vibrating diaphragm, and namely tension piece is integrated with vibrating diaphragm; When the interlude of this tension piece be a cross section is the cylinder of straight line, in fact this syllogic tension piece becomes one block of elastomeric material, and its one end is bonding with vibrating diaphragm termination, and the other end is bonding with framework.
A ribbon loudspeaker with hammock type elastic cord suspension system, it is characterized in that: it comprises hammock type elastic cord suspension system, further comprises following feature: it sets sheet (5) by elastic cord (1), U-shaped aluminium groove or plastic channel (3), magnet (7), elastic cord mounting panel (11), lug plate mounting panel (4), lug plate (12), aluminium belt diaphragm (2) and magnetic gap width and forms, aluminium strip two ends are fixed respectively, be suspended on elastic cord, magnet is arranged in the groove of U-shaped aluminium groove or plastic channel, all be fixed in the direction of the width on framework unlike the aluminium strip two ends in traditional aluminium strip high pitch loudspeaker, only some is fixed on elastic cord in the direction of the width at aluminium strip two ends in this ribbon loudspeaker, and the object done like this is the vibrational degrees of freedom strengthening vibrating diaphragm, usually, because the impedance of the aluminium belt diaphragm of ribbon loudspeaker is very little, be about 0.02 Ω, therefore ribbon loudspeaker needs outfit impedance matching transformer, to mate the requirement to loudspeaker impedance of power amplifier, and impedance matching transformer is because the existence meeting of coil is to the high frequency response generation harmful effect of loud speaker, the utility model proposes the following solution eliminating impedance matching transformer: utilize D class power amplifier conducting resistance very little for this reason, only has the feature of 0.22 Ω, ribbon loudspeaker is connected in series a little valued resistor, the resistance of this resistance can be as small as 0.2 Ω, then the ribbon loudspeaker being connected in series little valued resistor is connected on a D class power amplifier, in order to reduce speaker leads stress, prevent speaker leads from fractureing, the utility model proposes following solution: respectively weld a ultra-fine copper wire as speaker leads at aluminium belt diaphragm two ends, this copper wire is wound on elastic cord, finally draws from elastic cord termination bearing, noise is produced in order to prevent aluminium belt diaphragm, the utility model proposes following solution: a) prepare one piece of plank, some enamelled wire lines of coiling on plank, aluminium belt diaphragm is placed on enamelled wire lines, aluminium belt diaphragm is put one piece of erasing rubber, erasing rubber is put other one piece of plank, this plank applies pressure, thus make aluminium belt diaphragm produce some wire impressions on the surface, b) prepare hard wheel and one softly to take turns, some enamelled wire lines of coiling on hard wheel, by spring, hard is taken turns to contact with soft wheel, an aluminium strip is inserted in contact position, rotate hard wheel or softly to take turns, aluminium strip can move forward under the effect of frictional force, and the enamelled wire lines simultaneously on hard wheel can produce some wire impressions on the surface at aluminium strip, the framework of this ribbon loudspeaker has the flexible phase-reversing tube (6) of P bar, P is any positive integer, flexible phase-reversing tube refers to the paraphase flexible pipe that pipe itself can bend, and its cavity design be applied as after by earphone speaker becomes a miniature phase inverted cabinet to provide a kind of possibility, flexible phase-reversing tube also can be applicable to the design of general audio amplifier, limits the length of traditional rigidity phase-reversing tube to break audio amplifier inner space.
