Abstract
An amplitude limiting soft ring is arranged between a spring plate and a magnetic conduction hood of a large-power amplitude limiting vibration speaker; an amplitude limiting cushion is arranged between a quality loop and a rear cover. The utility mode has the functions of the prior vibrators and speakers, and overcomes the technical difficulties of distortion and clash brought by the increase of rated power.
Description
Technical field
The utility model belongs to other sound---pickoff group in International Patent Classification (IPC), i.e. H04R, the particularly vibrator used of mobile communication terminal, device, the parts of loud speaker unification.
Background technology
Mobile communication terminal is mobile phone, Personal Handyphone System, cordless telephone etc., and caller voice is reminded and generally used coil-moving speaker.Another kind of call reminding is used mode of vibration.This moment, vibrator and loud speaker were divided into two parts.When loud speaker and vibrator combine, produced vibrating speaker.The mobile communication terminal product can increase input signal to vibrating speaker in order to reach a bigger volume and stronger vibrating effect.When vibrating speaker receives the input signal of an increase, whole magnetic circuit can produce bigger Oscillation Amplitude, because the increase of magnetic circuit amplitude causes voice coil loudspeaker voice coil to occur and the magnetic circuit disengaged position when work, and the generation nonlinear distortion.After the increase of magnetic circuit amplitude, under the situation that keeps existing product thickness, will cause the bump of magnetic circuit and other assembly of product simultaneously, produce obviously vibration strike note.
The utility model content
The purpose of this utility model is not increase and provides a kind of under the condition of product thickness and can increase rated power, avoids vibrating strike note, and it is excessive and cause the vibrating speaker of distortion to solve the magnetic circuit amplitude.
It is as follows to disclose new technical scheme:
A kind of high-power limit amplitude vibration loud speaker, the coaxial voice coil loudspeaker voice coil that is fixed with the sound film, and coaxial being suspended in the magnetic circuit that constitutes by clamping plate, magnet steel, magnetism-guiding hood, the back side is stained with quality loop, latch plate, and coaxial and above-mentioned magnetic circuit combines, and is inlaid among the base, base be covered with protecgulum and bonnet up and down respectively, limit the soft circle of amplitude, anti-deformation support between latch plate and magnetism-guiding hood, between quality loop and the bonnet, the finite amplitude cushion.
Sample by scheme trial-production, because the mechanical damping of limit soft circle of amplitude and limit amplitude cushion has been arranged, thereby effectively reduced the magnetic circuit Oscillation Amplitude,, kept voice coil loudspeaker voice coil relevant position in magnetic circuit to avoid distortion so the magnetic circuit amplitude can limit within the specific limits when increasing applied signal voltage.Limit soft circle of amplitude and the distinctive physical property of limit amplitude cushion self when magnetic circuit is clashed into mutually with it, have had certain buffering, and having solved does not increase the requirement that product thickness just can be improved the vibration strike note.
Description of drawings
Fig. 1 is the cross-sectional schematic of an enforcement of the utility model, and Fig. 2 is the Knock-Down Component figure of Fig. 1.Wherein: 1, protecgulum 2, sound film 3, voice coil loudspeaker voice coil 4, clamping plate 5, magnet steel 6, magnetism-guiding hood 7, anti-deformation support 8, the soft circle 9 of limit amplitude, latch plate 10, base 11, quality loop 12, limit amplitude cushion 13, bonnet 14, terminal block.
Embodiment
A kind of high-power limit amplitude vibration loud speaker, the coaxial voice coil loudspeaker voice coil 3 that is fixed with sound film 2, and coaxial being suspended in by clamping plate 4, magnet steel 5, in the magnetic circuit that magnetism-guiding hood 6 constitutes, the back side is stained with quality loop 11, latch plate 9, coaxial and above-mentioned magnetic circuit combines, and be inlaid among the base 10, base 10 be covered with protecgulum 1 and bonnet 13 up and down respectively, the soft circle 8 of limit amplitude, anti-deformation support 7 is between latch plate 9 and magnetism-guiding hood 6, between quality loop 11 and the bonnet 13, finite amplitude cushion 12, base 10 is fixed with terminal block 14, and the lead-out wire of voice coil loudspeaker voice coil 3 links to each other with the positive/negative plate of terminal block 14 respectively.
