Embodiment
With reference to the accompanying drawings the present invention is described in more detail.
Fig. 3 is the stereogram of the mobile communication terminal structure of the loudspeaker assembly that is provided with one installation resonant tank among the present invention; Fig. 4 is that the one among the present invention is installed the loudspeaker assembly structure of resonant tank and the stereogram of mounting structure, and Fig. 5 is that the one among the present invention is installed the loudspeaker assembly structure of resonant tank and the sectional view of mounting structure.
In the following explanation of carrying out, for the basic technological thought of clear and definite the present invention saves specifying of known function or structurally associated.
To shown in Figure 5, the loudspeaker assembly of the one among the present invention being installed resonant tank adopts the example at hinged-lid mobile communication terminal to describe as Fig. 3.
Hinged-lid mobile communication terminal comprises body 120; Be folded to above-mentioned body 120, be positioned at and be used for the front of the above-mentioned body 120 of switch, but the turning cover part 130 that connects with respect to body 120 turns.Wherein, but relatively turn is in conjunction with above-mentioned body 120 in order to make turning cover part, and the set space that is separated by, the bottom of above-mentioned turning cover part 130 is formed with a pair of hinge portion (131) of renovating; The upper end of above-mentioned body 120 then is formed with body hinge portion 121, but makes its turn be incorporated into above-mentioned renovating between the hinge portion 131.
The front of above-mentioned turning cover part 130 is equipped with the display part 132 that is used to export set image information, and the upper end, front of turning cover part 130 then is provided with the receiver portion 133 that is used to transmit the other side's voice.
The inside of above-mentioned body 120 accommodates main printed circuit board 125, the traffic operation that is used to import various information and controls mobile communication terminal.The front of above-mentioned body 120 is provided with a plurality of buttons 122 that are used to import various information, and the microphone portion 123 that is used to transmit user speech, and its back side then is combined with battery 124 and can carries out dismounting.
And the inside of above-mentioned body 120 is equipped with the loudspeaker assembly 140 among the present invention, and is used to generate both sound press of sizing.Above-mentioned loudspeaker assembly 140 comprises: the loud speaker 141 that is used to produce sound press; Be integrally formed at the rear of above-mentioned loud speaker 141, and inner resonant tank 142 with sympathetic response space.
Wherein, above-mentioned loud speaker 141 fixedly mounts by the loud speaker accommodation section of the vertical extension that protrudes 126 formation of inner face of body 120.
For the sound press that makes the mesolow that produces in the rear area that compiles loud speaker 141 and carry out sympathetic response, the inside of above-mentioned resonant tank 142 forms multiple shapes such as rectangular cylinder or cylinder, makes the inside of above-mentioned resonant tank 142 have set sympathetic response space.When carrying out plane projection, above-mentioned resonant tank 142 is preferably compared the wideer area of above-mentioned loud speaker 141.
And, causing reducing tonequality for making the interference that prevents the reflection sound wave of reflection in the above-mentioned resonant tank 142, the back side of above-mentioned resonant tank 142 is formed with both leakages of sizing (leak) hole 142a with perforation.Above-mentioned leak 142a makes the part sound press in the mesolow sound press that produces in the rear area of loud speaker 140 leak into the outside of resonant tank 142, thereby realizes the sympathetic response effect of mobile communication terminal the best.Above-mentioned leak 142 is preferably formed as the core that reaches above-below direction in about resonant tank 142 back sides.
In addition, in above-mentioned explanation and illustrated embodiment, the tone quality improving apparatus among the present invention adopts and is illustrated at hinged-lid mobile communication terminal.But, also the tone quality improving apparatus among the present invention can be adopted at straight plate (bar) type and cover type mobile communication terminal.
More than the useful embodiment among the present invention is illustrated, but the present invention is defined in aforesaid embodiment, in not exceeding the claim scope of putting down in writing in claims, the operator of relevant industries can carry out suitable distortion to it.
As mentioned above, at the mobile communication terminal that one is installed the loudspeaker assembly of resonant tank that is provided with among the present invention, integrally formed resonant tank in the rear area of loud speaker, thus can improve the tonequality of loud speaker and satisfy demand in user's use.
