Background technology
Loud speaker as a kind of can be the device of acoustic energy by electric energy conversion, be now widely used in the terminal electronics such as computer, mobile phone, MP4, PDA.Along with electron trade and scientific and technical continuous progress and development, audient also must propose higher requirement for the acoustical behavior of loud speaker.Resonance frequency (F
0) be one of important indicator of loud speaker, resonance frequency is lower, and passband is then wider, and acoustical behavior is also better.
Existing loud speaker module, due to the restriction by space, its resonance frequency is general higher, and the method reducing resonance frequency in theory mainly contains increase back cavity, extends ante-chamber, uses thinner vibrating diaphragm and use heavier voice coil loudspeaker voice coil etc.But above-mentioned several method has its inevitable drawback and limitation: when cumulative volume is certain, increase back cavity inevitable conflicting with prolongation ante-chamber; Thinner vibrating diaphragm easily causes the potential risks such as polarization and rupture of membranes, and the whole structure that loud speaker module reduces resonance frequency by thinning vibrating diaphragm is very limited; Heavier voice coil loudspeaker voice coil then means higher or thicker voice coil loudspeaker voice coil, and BL (stress-electric coupling coefficient) nature can reduce.Therefore, as can be seen from the above analysis, reduce resonance frequency and there is no good plan.In addition, for Microspeaker module, easily there is resonance in its ante-chamber, and FH (frequency response curve medium-high frequency resonance peak) is the high frequency boundary of passband, and reducing FH is the effective ways widening passband, but there is no good measure at present.
Therefore, be necessary for the problems referred to above, the structure of loud speaker module is improved, to widen passband, improve its acoustical behavior.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of loud speaker module, in the front operatic tunes, arrange cavity configuration, reduces resonance frequency, improves radiation efficiency, optimizing product performance.
To achieve these goals, the utility model by the following technical solutions: a kind of loud speaker module, comprises module casing; Described module casing comprises module upper casing and module lower casing; Described module upper casing and described module lower casing complement each other to form the module inner chamber of accommodating loudspeaker monomer; Described loudspeaker monomer is the front operatic tunes and the rear operatic tunes described module lumen segmentation, wherein, obliquely in the described front operatic tunes is provided with partition wall; One end of described partition wall and a sidewall of described module lower casing are connected and fixed, and the other end is positioned at the described front operatic tunes and speaks the root position of passage, are formed to fall chamber in the described front operatic tunes.
Improve as one, described chamber is arranged at speaking on passage of the described front operatic tunes.
Improve as one, described partition wall is linear pattern, circular arc or index line style.
Improve as one, the other end of described partition wall is positioned at the described front operatic tunes and speaks the optional position of root passageway.
Improve as one, the other end of described partition wall is positioned at the described front operatic tunes and speaks the centre position of root passageway.
Improve as one, described loudspeaker monomer comprises vibrating diaphragm; Described vibrating diaphragm, described partition wall and described module lower casing form described chamber.
Improve as one, described chamber is collapsible horn structure.
Improve as one, another sidewall of described module lower casing is provided with the phonate hole of module; The front operatic tunes of described module is communicated with described phonate hole.
Improve as one, described module upper casing is provided with ultrasound lines pedestal; Described ultrasound lines pedestal is provided with ultrasound lines, the described chamber of sealing.
Due to loud speaker module of the present utility model, obliquely in the front operatic tunes be provided with partition wall, one end of partition wall and a sidewall of module lower casing are connected and fixed, the other end is positioned at the front operatic tunes and speaks the root position of passage, chamber is formed in the front operatic tunes, this kind of design equivalence can extend the front operatic tunes, increases acoustic mass, thus effectively reduces resonance frequency.
Because chamber is collapsible horn structure, this design effectively can increase radiation resistance, improves radiation efficiency, thus makes up the defect of the product sensitivity decrease caused because increasing acoustic mass.
Shape due to partition wall can be linear pattern, circular arc or index line style, the shape of partition wall is optimized to the sensitivity that can also improve speaker product further.
In sum, arrange cavity configuration in the operatic tunes before module, effectively can suppress the resonance phenomena of the front operatic tunes, thus reduce frequency response curve medium-high frequency resonance peak FH, widen passband, improve high frequency radiation, can effectively reduce the harmonic distortion caused because of the resonance of the front operatic tunes simultaneously, optimize the acoustical behavior of speaker product.
