Abstract
A kind of Microspeaker, including vibrating diaphragm, support the frame of vibrating diaphragm, and the medial surface of vibrating diaphragm is fixed with voice coil loudspeaker voice coil, and vibrating diaphragm is fixed with vibration damping part, and vibration damping part vibrates with vibrating diaphragm.Vibration damping part reduces the natural resonance frequency of vibrating diaphragm, extends the middle bass zone of Microspeaker, improves the frequency response of Microspeaker, smooths bass response, and bass is simple and honest, plentiful.
Description
Technical field
The utility model is related to electro-acoustic element, more particularly to Microspeaker.
Background technology
Microspeaker is mostly used for the mobile units such as mobile phone, earphone.The diaphragm diameter of Microspeaker is smaller.It is micro- to improve
The low frequency acoustics of type loudspeaker, at present using the measure of the setting air damping in the resonator for installing Microspeaker, however,
Due to the limitation of physical dimension, tone quality improving difficulty is larger.
Utility model content
The purpose of this utility model is to provide a kind of Microspeaker, to improve the low frequency acoustics of Microspeaker.
What the utility model was realized in：A kind of Microspeaker, including vibrating diaphragm, support vibrating diaphragm frame, vibrating diaphragm it is interior
Side is fixed with voice coil loudspeaker voice coil, and vibrating diaphragm is fixed with vibration damping part, and vibration damping part vibrates with vibrating diaphragm.
Preferably, the vibration damping part is fixed on the medial surface of the vibrating diaphragm.
Preferably, the vibration damping part is a cylinder concentric with the voice coil loudspeaker voice coil, the end face of cylinder and the vibrating diaphragm
Medial surface bonding, the external diameter of the internal diameter of cylinder more than the voice coil loudspeaker voice coil.
Preferably, the vibration damping part is coiled into by lametta.
Preferably, the lametta is enamel-covered wire, and the head and the tail two ends of enamel-covered wire do not connect.
The vibrating diaphragm being preferably located between the voice coil loudspeaker voice coil and the vibration damping part arches upward towards outside, forms a circle convex
Ring, and/or, the vibrating diaphragm between the vibration damping part and the frame arches upward towards outside, forms one and encloses bulge loop.
The utility model has the advantages that, vibration damping part reduces the natural resonance frequency of vibrating diaphragm, extends Microspeaker
Middle bass zone, improve the frequency response of Microspeaker, make bass response smooth, bass is simple and honest, plentiful.
Brief description of the drawings
Fig. 1 is the structural representation of Microspeaker；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
Referring to Fig. 1 and Fig. 2 is combined, the Microspeaker includes vibrating diaphragm 1, support the medial surface of the frame 2 of vibrating diaphragm, vibrating diaphragm 1 to glue
Voice coil loudspeaker voice coil 3 is connected to, vibration damping part 4 is fixed with the medial surface of vibrating diaphragm 1, vibration damping part 4 vibrates with vibrating diaphragm 1.Vibration resistance
Damping member 4 is a cylinder concentric with voice coil loudspeaker voice coil 3, and the end face of cylinder is Nian Jie with the medial surface of vibrating diaphragm 1, and the internal diameter of cylinder is more than voice coil loudspeaker voice coil
3 external diameter.Used as preferred forms, vibration damping part 4 is coiled into by lametta, can thus use the equipment of manufacture voice coil loudspeaker voice coil
Vibration damping part is manufactured with technique, production is convenient to.Lametta can be bare copper wire.But as preferred forms, carefully
Metal wire should be enamel-covered wire, and the head and the tail two ends of enamel-covered wire do not connect, in this way, vibration damping part 4 can be avoided to be subject to miniature loudspeaker
In magnet 5 influence, prevent vibration damping part 4 and the vibration of vibrating diaphragm 1 seriously hindered because induced-current is produced.
As a further improvement, the vibrating diaphragm between voice coil loudspeaker voice coil 3 and vibration damping part 4 arches upward towards outside, form one and enclose
Bulge loop 1a.Extension alt domain can so be played a part of.More preferably, the vibrating diaphragm 1 between vibration damping part 4 and frame 2
Also arched upward towards outside, form one and enclose bulge loop 1b.Extension effect so to alt domain is more obvious, can preferably improve sound
Matter.
It is understood that the planform of vibration damping part is not limited to above-described embodiment, for example, vibration damping part can be with
It is one piece of laminar annulus, its material can be plastics, for laminar vibration damping part, can be bonded in vibrating diaphragm
Lateral surface.
