Abstract
The utility model discloses an audio structure for a mobile phone. The audio structure for the mobile phone comprises a shell provided with a sound cavity formed by enclosing, wherein a loudspeaker which is fixed on the shell is arranged in the sound cavity; at least one passive radiator is arranged on the shell; the passive radiator comprises a vibrating diaphragm and a folding ring; and the folding ring is fixed with the shell. The audio structure for the mobile phone is high in sensitivity, low in standing wave influence, and clear and transparent in sound; and the working amplitude of the loudspeaker can be reduced effectively.
Description
Technical field
The utility model relates to a kind of acoustic structure, specifically a kind of acoustic structure that is mainly used on the mobile phone.
Background technology
Along with the progress of the development of society, science and technology, the improving constantly of living standard, people are also increasingly high to the requirement of mobile phone.After the leisure of work, study, people can emit music through mobile phone, and the mood of oneself is loosened, and mood is releived.Present mobile phone is generally only installed set of speakers in interior and is sounded, and perhaps loud speaker is installed in the simple airtight sound chamber and sounds.More than two kinds of frame modes, all have only the positive sound wave energy of loud speaker to access effective utilization, and the sound wave at the loud speaker back side is not used, the lower frequency limit of sound system is higher, mobile phone is when playing back music, the effect of middle bass is generally relatively poor.
Summary of the invention
The utility model has solved technical problems such as the mobile phone sound equipment LF-response that exists in the prior art is poor, sound is Clear & Transparent inadequately, and a kind of pure natural, mobile phone acoustic structure that acoustical quality is good of low-frequency sound that makes is provided.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of mobile phone acoustic structure comprises surrounding the housing that is formed with the sound chamber that be provided with the loud speaker that is fixed on the housing in the sound chamber, said housing is provided with passive radiator.
Said passive radiator comprises vibrating diaphragm and ring, and ring and housing fix.
As to above-mentioned improvement, said passive radiator is provided with one at least.
As to above-mentioned further improvement, said sound chamber is closed sound chamber.
The utility model passes through improvements over the prior art; On the sound chamber of mobile phone, passive radiator is set; Radiation sound and loud speaker forward radiation sound that the passive radiator vibration produces are in the push-push operation state; Utilize air and the genial passive radiator quality formation of the common complex sound that constitutes of passive radiator support component resonance in the casing, strengthen bass.The audio cavity structure of the utility model prompting mainly is a unsettled sound of having avoided the reflection phonate hole to produce; Even volume not quite also can obtain good acoustic radiation effect; So highly sensitive, can effectively reduce the speaker operation amplitude, the standing wave influence is little; Sound is Clear & Transparent, makes the pure nature of low-frequency sound simultaneously.
Description of drawings
Accompanying drawing 1 is the cross-sectional view of the utility model execution mode one;
Accompanying drawing 2 is the cross-sectional view of the utility model execution mode two.
Embodiment
For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, the utility model has disclosed a kind of mobile phone acoustic structure, comprises surrounding the housing 3 that is formed with sound chamber 1, and be provided with the loud speaker 2 that is fixed on the housing 3 in the sound chamber 1, said housing 3 is provided with passive radiator 4.This passive radiator 4 comprises vibrating diaphragm 41 and plays the ring 42 of reset response, shake touch 41 be positioned at whole passive radiator 4 the centre position, ring 42 is positioned at side, passive radiator 4 fixes through ring 42 and housing 3.
Passive radiator 4 can be provided with one, two, three or more a plurality of; Do not enumerate to such an extent that the vibration displacement of passive radiator reduces one by one at this; The swept area of passive radiator makes the vibration displacement of passive radiator reduce greater than the swept area of loud speaker, more effectively is controlled in the effective linear displacement; Distortion is just little, and the transient response characteristic of low frequency improves.The concrete quantity of passive radiator can be chosen according to actual conditions flexibly.The sound chamber is closed sound chamber, and acoustical quality is better
In addition, when design, the housing 3 that surrounds audio chamber 1 can be direct integral type, shown in accompanying drawing 1.In this version, the ring 42 of passive radiator 4 is directly fixing with housing 3.Sound chamber 1 also can be to be surrounded by the shell 5 of phase attaching and pcb board 6 to form, shown in accompanying drawing 2.In this version, the ring 42 and the pcb board 6 of passive radiator 4 fix, thereby realize the fixing of whole passive radiator.
In practical set, what the bore of passive radiator and outstanding limit can be with loud speakers is identical, perhaps big than loud speaker.And loud speaker can be coil-moving speaker, perhaps relevant loud speaker with piezoelectric ceramic loudspeaker, and the structure of loud speaker itself is not done detailed giving unnecessary details to it for existing known technology at this.
Need to prove; Because the type of mobile phone is varied; And in order to obtain best acoustical quality; The size of the airtight cavity in the sound chamber and shape can be come concrete the setting according to the difference of mobile phone, and the shape of passive radiator can be not to be to immobilize according to the size and the shape setting of corresponding airtight cavity yet.
