Embodiment
First embodiment
Please be simultaneously with reference to Fig. 2, Fig. 3, Figure 2 shows that according to the loudspeaker mechanism 110 of first embodiment of the invention and use its electronic installation 100 schematic diagrames.Figure 3 shows that the loudspeaker mechanism 110 of Fig. 2 and use the exploded view of its electronic installation 100.Electronic installation 100 comprises a housing 120, a control unit 140 and a loudspeaker mechanism 110.Control unit 140 is arranged in the housing 120.Loudspeaker mechanism 110 comprises an audio amplifier 111, a loudspeaker element 112 and a sound compensation element 113.Loudspeaker element 112 is arranged at audio amplifier 111 surfaces.Control unit 140 is electrically connected to loudspeaker element 112, sends a sound signal S1 with control loudspeaker element 112.Sound compensation element 113 is arranged at audio amplifier 114 surfaces.Sound compensation element 113 comprises a resonance film 1131 and a weightening finish element 1132.Resonance membrane 1131 resonates in a resonance frequency scope, is generally 400 hertz (Hz) first resonance point to loudspeaker element 112, with compensating sound signal S1 in the intensity of sound of resonance frequency scope.Weightening finish element 1132 is attached at the surface of resonance membrane 1131.The weight of weightening finish element 1132 is relevant with the resonance frequency scope.
In the present embodiment, the resonance frequency scope of sound compensation element 113 in 400 hertz (Hz) to 500 hertz (Hz) has best resonance effect.Generally speaking, the audio amplifier 111 of small size (for example is below 4 cubic centimetres, in the present embodiment, the volume of audio amplifier 111 is 1.5 cubic centimetres) in 400 hertz (Hz) poor effect to the lower resonant frequency scope of 500 hertz (Hz), by sound compensation element 113 of the present invention, can compensate 400 hertz (Hz) sound signal S1 effectively to the resonance frequency scope of 500 hertz (Hz).
In addition, the 3rd opening 111c of audio amplifier 111 more can be coupled to housing 120 except can being coupled to circuit board 130, to form closed space.The structural design of user's visible electronic device 100 is done suitable adjustment.
As shown in Figure 2, loudspeaker element 112 and sound compensation element 113 are positioned at same audio amplifier 111.When the sound signal S1 that loudspeaker element 112 is sent resonated in audio amplifier 111, sound compensation element 113 also received sound signal S1, and synchro-resonance is to strengthen sound signal S1.
Moreover the loudspeaker element 112 of present embodiment and sound compensation element 113 are arranged at the same side (being the positive direction of Z axle) of audio amplifier 111.By this, loudspeaker element 112 and sound compensation element 113 can be transmitted sound signal S1 towards same direction, to obtain the effect of resonance.
Please refer to Fig. 3, in the process of resonance membrane 1131 along with sound signal S1 resonance, the weight of weightening finish element 1132 is relevant with the resonance frequency scope.The user can be suitable the weight of adjustment weightening finish element 1132 (for example be 100～300 milligrams (mg), in the present embodiment, the weight of weightening finish element 1132 is 200 milligrams), can make the resonance frequency scope of sound compensation element 113 in 400 hertz (Hz) to 500 hertz (Hz) of present embodiment obtain best effect.
Please refer to Fig. 4, Fig. 5, Figure 4 shows that the loudspeaker mechanism 110 of Fig. 2 and use the vertical view of its electronic installation 100, Figure 5 shows that the profile of the loudspeaker mechanism 110 of Fig. 4 along section line 5-5 '.As shown in Figure 5, weightening finish element 1132 attaches the centre of resonance membrane 1131.Resonance membrane 1131 is in resonance process, because weightening finish element 1132 has certain weight, resonance membrane 1132 is swingingly comparatively slow.Make the sound compensation element 113 of present embodiment in low frequency ranges, produce resonance at an easy rate.
As please refer to Fig. 6, it is depicted as the measurement figure of the loudspeaker mechanism 110 of present embodiment.Curve A represents not attach the measurement curve of the resonance membrane 1131 of weightening finish element 1132, and curve B represents to attach the measurement curve of the resonance membrane 1131 of weightening finish element 1132.The transverse axis of Fig. 6 is represented resonance frequency (Hz), and the longitudinal axis is represented yield value (dB).With curve A and curve B relatively, curve B obviously exceeds curve A many (shown in the dashed region of Fig. 6) at 400 hertz (Hz) to the yield value in the resonance frequency scope of 500 hertz (Hz).That is to say that the loudspeaker mechanism 110 that is pasted with weightening finish element 1132 has splendid effect at 400 hertz (Hz) to the resonance frequency scope of 500 hertz (Hz).
In addition, the material of resonance membrane 1131 also can influence the resonance frequency scope of sound compensation element 113.Generally speaking, the resonance frequency of hard more material (for example being metal) is high more; The resonance frequency of soft more material (for example being plastics) is low more.In the present embodiment, the purpose of sound compensation element 113 is the sound signal S1 in order to the compensation bass frequency range, so adopt the resonance membrane 1131 of plastic film as present embodiment.
Moreover the thickness of resonance membrane 1131 also can influence the resonance frequency scope of sound compensation element 113.The thickness of resonance membrane 1131 is thin more, and the easy more swing of resonance membrane 113 makes that the resonance frequency of resonance membrane 1131 is high more.The thickness of resonance membrane 1131 is thick more, and resonance membrane 1131 is not easy swing more, makes that the resonance frequency of resonance membrane 1131 is low more.The user can adjust the thickness of resonance membrane 1131 according to actual demand.
As mentioned above, no matter be that the weight of weightening finish element 1132, the material or the thickness of resonance membrane 1131 of resonance membrane 1131 all can make sound compensation element 113 resonate in the resonance frequency scope that desire is strengthened through after the suitable adjustment.
In addition, if desire increases the air-tightness of audio amplifier 111, the structure that resonance membrane 1131 can be formed in one with audio amplifier 111 is to keep audio amplifier 111 good air-tightness.Perhaps, when resonance membrane 1131 and audio amplifier 111 are selected unlike material for use, also can be assembled into a confined space by rubber or sponge.
As mentioned above, the reinforcement sound signal S1 in the lower resonant frequency scope of sound compensation element 113 makes loudspeaker mechanism 110 under the volume of element that does not increase any complexity (for example being another loudspeaker) or increase audio amplifier 111, can obtain best bass effect.
