請合併參閱圖1及圖2，本申請的一種微型揚聲器模組100包含第一殼體110、第二殼體120、頂蓋130、振膜組件140及出音口貼片150。其中，如圖2所示，第一殼體110具有第一容置空間112。第二殼體120組接設置於第一殼體110上方。第二殼體120具有第二容置空間122及導音管124，第二容置空間122對應於第一殼體110的第一容置空間112，且如圖4所示，第二容置空間122延伸至導音管124。請再次參閱圖2，第二殼體120外側面具有開口126，開口126與第二容置空間122相連通，頂蓋130設置於第二殼體120外側並覆蓋開口126。振膜組件140夾設於第一殼體110的第一容置空間112與第二殼體120的第二容置空間122之間。出音口貼片150設置於導音管124的導音管出口124a。Please refer to FIG. 1 and FIG. 2 together, a miniature speaker module 100 of the present application includes a first casing 110 , a second casing 120 , a top cover 130 , a diaphragm assembly 140 and a sound outlet patch 150 . Wherein, as shown in FIG. 2 , the first housing 110 has a first accommodating space 112 . The second casing 120 is assembled and disposed above the first casing 110 . The second housing 120 has a second accommodating space 122 and a sound guide tube 124. The second accommodating space 122 corresponds to the first accommodating space 112 of the first housing 110, and as shown in FIG. 4, the second accommodating space 122 corresponds to the first accommodating space 112 of the first housing 110 The space 122 extends to the sound guide tube 124 . Referring to FIG. 2 again, the outer side of the second casing 120 has an opening 126 , the opening 126 communicates with the second accommodating space 122 , and the top cover 130 is disposed outside the second casing 120 and covers the opening 126 . The diaphragm assembly 140 is sandwiched between the first accommodating space 112 of the first casing 110 and the second accommodating space 122 of the second casing 120 . The sound outlet patch 150 is disposed on the sound guide tube outlet 124 a of the sound guide tube 124 .

於本實施例中，導音管124呈長條管狀，且連通第二容置空間122的一端呈彎曲設置，而另一端則朝外側延伸形成導音管出口124a，並讓導音管124出音的一端平行於第二殼體120的外側表面。另外，需進一步說明的是，振膜組件140包含有音圈、上極片、下極片與磁鐵等組件，關於振膜組件140的結構為現有常見的可供電磁運作發聲的結構，因此，在此不再詳細贅述。In this embodiment, the sound guide tube 124 is in the shape of a long tube, and one end that communicates with the second accommodating space 122 is curved, while the other end extends outward to form the sound guide tube outlet 124a, and allows the sound guide tube 124 to exit. One end of the sound is parallel to the outer side surface of the second housing 120 . In addition, it should be further noted that the diaphragm assembly 140 includes components such as a voice coil, an upper pole piece, a lower pole piece, a magnet, and the like. The structure of the diaphragm assembly 140 is a conventional structure that can be used for electromagnetic operation and sound. Therefore, The details are not repeated here.

詳細而言，請一併參閱圖2及圖4，由於導音管124連通第二容置空間122的一端為局部彎曲朝上，故第二殼體120與導音管124的連通處便相應地具有呈斜面狀朝下設置的通孔128。換言之，第二殼體120是通過斜面狀朝下設置的通孔128與導音管124的局部彎曲端連接，使第二殼體120的第二容置空間122可延伸至導音管124並與導音管124的導音管出口124a連通，從而具有將振膜組件140振動時所產生的聲學負載（即：聲壓）傳遞至導音管124的導音管出口124a的效果。In detail, please refer to FIG. 2 and FIG. 4 together. Since the end of the sound guide tube 124 that communicates with the second accommodating space 122 is partially bent upward, the connection between the second shell 120 and the sound guide tube 124 is corresponding The ground has a through hole 128 downwardly arranged in an inclined plane. In other words, the second housing 120 is connected to the partially bent end of the sound guide tube 124 through the through hole 128 disposed downward in a slope shape, so that the second accommodating space 122 of the second housing 120 can extend to the sound guide tube 124 and It communicates with the sound guide pipe outlet 124 a of the sound guide pipe 124 , so as to transmit the acoustic load (ie, sound pressure) generated when the diaphragm assembly 140 vibrates to the sound guide pipe outlet 124 a of the sound guide pipe 124 .

請再次參閱圖2，於本申請的微型揚聲器模組100中，出音口貼片150的出音口152具有出音口面積A1，導音管124的導音管出口124a具有導音管出口面積A2，且出音口面積A1小於導音管出口面積A2。透過出音口面積A1小於導音管出口面積A2的特殊設置，振膜組件140振動時所產生的聲學負載傳遞至導音管124的導音管出口124a後，將會受到出音口貼片150的阻擋，從而加大自出音口152處所對應輸出的聲學負載，因而可以如圖6所示，於低頻感度的部分基本無影響，於中頻感度3kHz~4.2kHz的部分有所增加，於中頻感度4.5kHz~5kHz的部分稍微下降，但是於高頻感度9kHz~12kHz的部分則有明顯提升，因此能夠顯著地優化本申請的微型揚聲器模組100在高頻區段的表現。Please refer to FIG. 2 again, in the micro speaker module 100 of the present application, the sound outlet 152 of the sound outlet patch 150 has a sound outlet area A1, and the sound guide pipe outlet 124a of the sound guide pipe 124 has a sound guide pipe outlet Area A2, and the area A1 of the sound outlet is smaller than the area A2 of the outlet of the sound guide tube. Through the special setting that the area A1 of the sound outlet is smaller than the area A2 of the outlet of the sound guide tube, the acoustic load generated when the diaphragm assembly 140 vibrates is transmitted to the sound guide tube outlet 124a of the sound guide tube 124, and will be affected by the sound outlet patch 150, so as to increase the acoustic load corresponding to the output from the sound outlet 152. Therefore, as shown in Figure 6, the low-frequency sensitivity is basically unaffected, and the mid-frequency sensitivity is increased from 3kHz to 4.2kHz. The mid-frequency sensitivity of 4.5 kHz to 5 kHz is slightly decreased, but the high-frequency sensitivity of 9 kHz to 12 kHz is significantly improved, so the performance of the micro speaker module 100 of the present application in the high frequency range can be significantly optimized.

於本申請的較佳實施態樣中，出音口面積A1為導音管出口面積A2的0.25~0.5倍。此外，如圖1-圖3所示的實施例中，出音口貼片150的出音口152可為橫向開口，或是如圖5所示，出音口貼片150的出音口152可為縱向開口，但並非以此作為限制。In a preferred embodiment of the present application, the area A1 of the sound outlet is 0.25-0.5 times the area A2 of the outlet of the sound guide tube. In addition, in the embodiment shown in FIGS. 1-3 , the sound outlet 152 of the sound outlet patch 150 may be a horizontal opening, or as shown in FIG. 5 , the sound outlet 152 of the sound outlet patch 150 Longitudinal openings are possible, but not limited thereto.

需進一步說明的是，出音口152的形狀設置可以為但不限於如圖1-圖3所示中為矩形開口狀，當然也可依據製造者的實驗測試而定，可為其他形狀的開口，例如三角形開口、圓形開口或多邊形開口…等，僅需達到如圖6所示的高頻區段的表現即可視為本申請所請求保護的範圍。It should be further noted that the shape of the sound outlet 152 can be, but is not limited to, a rectangular opening as shown in FIGS. 1 to 3 . Of course, it can also be determined according to the manufacturer’s experimental test, and can be other shapes of openings. , such as a triangular opening, a circular opening or a polygonal opening, etc., only the performance of the high frequency section as shown in FIG. 6 can be regarded as the scope of protection claimed by the present application.

此外，於本申請的微型揚聲器模組100中，出音口貼片150是以貼合方式固定於導音管124的導音管出口124a，且出音口貼片150的材質為塑膠或矽膠，因此，出音口貼片150具有一定的彈性力，可於出音時產生共振與擋音的作用。如此一來，由於所增設的出音口貼片150無須透過額外的結構組裝於導音管124的導音管出口124a，且出音口貼片150僅為輕薄的塑膠或矽膠，因此並不會對原有的可攜式設備的整體設計造成影響，甚至可直接沿用原有的可攜式設備的設計進行組裝，從而能減少設計成本與避免更改原有結構的問題。In addition, in the miniature speaker module 100 of the present application, the sound outlet patch 150 is fixed to the sound guide tube outlet 124a of the sound guide tube 124 in a bonding manner, and the material of the sound outlet patch 150 is plastic or silicone Therefore, the sound outlet patch 150 has a certain elastic force, which can produce resonance and sound blocking effects when sound is emitted. In this way, since the added sound outlet patch 150 does not need to be assembled to the sound guide tube outlet 124a of the sound guide tube 124 through an additional structure, and the sound outlet patch 150 is only made of thin plastic or silicone, it does not need to be assembled. It will affect the overall design of the original portable device, and even directly follow the design of the original portable device for assembly, thereby reducing the design cost and avoiding the problem of changing the original structure.

請參閱圖2及圖3，於本申請的微型揚聲器模組100中，當振膜組件140夾設於第一殼體110的第一容置空間112與第二殼體120的第二容置空間122之間時，振膜組件140與位在下方的第一殼體110的第一容置空間112用於形成聲學後腔（圖未示出）。當振膜組件140夾設於第一殼體110的第一容置空間112與第二殼體120的第二容置空間122之間時，振膜組件140、第二殼體120的第二容置空間122及頂蓋130用於形成聲學前腔（圖未示出）。透過上述的設置，振膜組件140所產生的振動便能夠在聲學前腔與聲學後腔之間輸出相對應的高頻效果與低頻效果。Please refer to FIG. 2 and FIG. 3 , in the micro speaker module 100 of the present application, when the diaphragm assembly 140 is sandwiched between the first accommodating space 112 of the first casing 110 and the second accommodating space of the second casing 120 Between the spaces 122 , the diaphragm assembly 140 and the first accommodating space 112 of the first housing 110 located below are used to form an acoustic back cavity (not shown). When the diaphragm assembly 140 is sandwiched between the first accommodating space 112 of the first casing 110 and the second accommodating space 122 of the second casing 120 , the diaphragm assembly 140 , the second accommodating space 122 of the second casing 120 The accommodating space 122 and the top cover 130 are used to form an acoustic front cavity (not shown in the figure). Through the above arrangement, the vibration generated by the diaphragm assembly 140 can output corresponding high-frequency effects and low-frequency effects between the acoustic front cavity and the acoustic rear cavity.

如圖4所示，由於第二殼體120所具有的第二容置空間122通過斜面狀朝下設置的通孔128連通至導音管124，因此當振膜組件140、第二容置空間122及頂蓋130形成聲學前腔時，聲學前腔便通過通孔128連通於導音管124的導音管出口124a。As shown in FIG. 4 , since the second accommodating space 122 of the second housing 120 is connected to the sound guide tube 124 through the through hole 128 provided downwardly in a slope shape, when the diaphragm assembly 140 and the second accommodating space are When the acoustic front chamber 122 and the top cover 130 form an acoustic front chamber, the acoustic front chamber is communicated with the sound guide pipe outlet 124a of the sound guide pipe 124 through the through hole 128 .

綜上所述，本申請的微型揚聲器模組100乃是透過出音口貼片150的設置，使出音口貼片150的出音口面積A1小於導音管出口124a的導音管出口面積A2，藉此加大自出音口152處所對應輸出的聲學負載，從而優化微型揚聲器模組在高頻區段的表現。此外，所增設的出音口貼片150無須透過額外的結構設計便可貼合於導音管124的導音管出口124a，且出音口貼片150僅為輕薄的塑膠或矽膠，因此並不會對原有的可攜式設備的整體設計造成影響，而得以直接沿用原有的可攜式設備的設計進行組裝。To sum up, the micro-speaker module 100 of the present application is configured by the sound outlet patch 150, so that the sound outlet area A1 of the sound outlet patch 150 is smaller than the sound guide outlet area of the sound guide pipe outlet 124a A2, thereby increasing the acoustic load corresponding to the output from the sound outlet 152, thereby optimizing the performance of the micro speaker module in the high frequency range. In addition, the added sound outlet patch 150 can be attached to the sound guide tube outlet 124a of the sound guide tube 124 without additional structural design, and the sound outlet patch 150 is only made of thin plastic or silicone, so it does not The overall design of the original portable device will not be affected, and the design of the original portable device can be directly used for assembly.
