Abstract
The utility model relates to sound technique field, disclose a kind of low frequency expanding micro loud speaker, loud speaker is arranged in the end face installing port of audio amplifier, its open end is outside audio amplifier, be provided with support ring between the outer surface of cupular part of described loud speaker and audio amplifier, support ring can produce vibration under external force.The shape of described support ring adopts semi-circular, arc or W waveform, and the both sides of openend are connected with loud speaker and audio amplifier respectively.Loud speaker suspends by increasing support ring by the utility model, drives support ring vibration, thus produce in-phase stacking extension low frequency by loudspeaker vibration, and reduces the intermodulation distortion that phase difference causes.
Description
Technical field
The utility model relates to sound technique field, in particular, and particularly a kind of low frequency expanding micro loud speaker.
Background technology
Along with portable sound reproduction equipment constantly increases, as mobile phone etc. needs the playback realizing low frequency by connecting audio amplifier.And current Microspeaker is the volume-variation of vibration area by unit and casing itself, or realized the transmission of sound by different acoustic construction, but and fail effectively to realize the expansion of low frequency.
Summary of the invention
The purpose of this utility model is the technical problem existed for prior art, a kind of low frequency expanding micro loud speaker is provided, by increasing support ring, loud speaker is suspended, support ring vibration is driven by loudspeaker vibration, thus produce in-phase stacking extension low frequency, and reduce the intermodulation distortion that phase difference causes.
In order to solve problem set forth above, the technical solution adopted in the utility model is:
A kind of low frequency expanding micro loud speaker, loud speaker is arranged in the end face installing port of audio amplifier, and its open end, outside audio amplifier, is provided with support ring between the outer surface of cupular part of described loud speaker and audio amplifier, and support ring can produce vibration under external force.
The shape of described support ring adopts semi-circular, arc or W waveform, and the both sides of openend are connected with loud speaker and audio amplifier respectively.
Described support ring adopts the rubber-like or the foamed cotton class that have toughness and damping material concurrently.
Effective vibration area of described support ring is that loud speaker effectively vibrates 1.5 times of area to 2 times.
Compared with prior art, the beneficial effects of the utility model are:
The extension of low frequency can be realized in less audio amplifier volume in the utility model, reduce to produce the sound dye of audio amplifier and the wind noise of phase-reversing tube because adopting inverted phase type design, and by loud speaker and irradiator integration, can effectively save audio amplifier space, and add support ring, produce the effect of sound source in-phase stacking by the control of loud speaker itself vibrates, reduce the sound wave interference that phase difference causes, make sound closer to same sound source, reduction degree strengthens; In addition, add support ring, namely within the scope of less audio amplifier, synchronous passive radiator can be realized by the quality of Microspeaker itself, and the effect of more air and the low frequency that extends can be promoted.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model low frequency expanding micro loud speaker is arranged on audio amplifier.
Fig. 2 is the partial structurtes schematic diagram of the utility model low frequency expanding micro loud speaker.
Embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Preferred embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present utility model more comprehensively thorough.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in specification of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.
Consult shown in Fig. 1 and Fig. 2, a kind of low frequency expanding micro loud speaker that the utility model provides, the end face of audio amplifier 1 is processed with installing port, loud speaker 3 is arranged in the installing port of audio amplifier 1, the open end of loud speaker 3, outside audio amplifier 1, is provided with support ring 2 between the outer surface of cupular part of loud speaker 3 and audio amplifier 1.
The shape of described support ring 2 can adopt semi-circular, arc or W waveform, and material adopts the rubber-like or the foamed cotton class that have toughness and damping material concurrently, namely can produce vibration under external force.The both sides of support ring 2 openend are connected with loud speaker 3 and audio amplifier 1 respectively.
In above-mentioned, effective vibration area of support ring 2 is 1.5 times to 2 times that loud speaker 3 effectively vibrates area.
In above-mentioned, loud speaker 3 adopts double magnetic circuit two-tone ring to design, and its swept area is large, from as the effect that act as passive radiator while loud speaker, in limited space, effectively promote LF-response, the nonlinear distortion that the irregular oscillations such as its internal vibration plate produce can also be reduced.Loud speaker 3 also can adopt single magnetic circuit single-tone circle, can increase support ring 2 equally to improve acoustic efficiency and low frequency extension.
In above-mentioned, by increasing support ring 2, loud speaker 3 being suspended, being vibrated by loud speaker 3 and driving support ring 2 to vibrate, thus producing in-phase stacking extension low frequency, and reduce the intermodulation distortion that phase difference causes.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
