Ceramic speaker sound output improver

This creation is about a sound output improver, especially a sound output improver for ceramic speakers.

As portable electronic products continue to develop lightly and thinly, ceramic horns with thinner, smaller, and lower power consumption advantages are increasingly favored by designers, and it is highly likely to replace traditional horns in the future. For example, ceramic horns have been installed on ultra-thin smart mobile phones.

However, because the characteristics of ceramics are hard and brittle, and the bass (or low-frequency sound) requires a large amplitude and diaphragm, the bass output of the ceramic speaker is less obvious, and this is a major defect of the ceramic speaker. .

As described above, since the treble portion of the ceramic horn is significantly more prominent than the bass portion, as shown in the first and second high frequency portions H1 and H2 in the response diagram shown in Fig. 1, thus the listener When the ear hears it, it will not sound like the bass part, and as a result, the sound of the treble is obviously lower and louder, and the listener will be quite uncomfortable and feels noisy, and these ceramic horns The shortcomings still cannot be successfully overcome.

Therefore, how to design a novel that can improve the above-mentioned defects is a major issue that the creators of this case want to solve.

The main purpose of this creation is to provide a sound output improver for ceramic horns, which can attenuate the two high-frequency parts to an appropriate size by means of a high-frequency cut-off device and a band-stop device, respectively. The bandage device can modify the originally harsh and noisy part, and finally the signal amplifying device can amplify the attenuated portion, so that the original defect of the ceramic horn: the high frequency portion is significantly lower. The frequency is highlighted, and it can be perfectly improved. The whole sound (all sound effects) that the listener hears will be more average and smooth.

In order to achieve the above objective, the present invention provides a sound output output improver for a ceramic horn, comprising: a high frequency cutoff device, a band stop device and a signal amplifying device, and the band stop device is coupled to the high frequency cutoff device The signal is amplified between the devices. Wherein, the high frequency cutoff device is provided with a plurality of capacitive elements and a fifth resistive element, the fifth resistive element being coupled to the second of the plurality of capacitive elements to attenuate a high frequency portion of the sound effect; The band stop device is provided with a plurality of capacitive elements and a plurality of resistive elements to attenuate another high frequency portion of the sound effect, the band stop device comprising a first via portion and a second via portion coupled to each other, The first via portion is provided with a first resistive element, a second resistive element and a fifth capacitive element coupled to each other, the second via portion is provided with a third capacitive element coupled to each other, and a fourth The capacitive element and a third resistive element, wherein the low frequency portion and the high frequency portion of the sound effect pass through the first and second passage portions, respectively.

In this way, in order to make the ceramic horn's original defect: the high-frequency part is obviously lower and the frequency part is prominent, and it can be perfectly improved, and all the sounds (all sound effects) that the listener hears will be more average and smooth.

The first via portion 21 is provided with a first resistive element R1 and a second coupled to each other. a resistor element R2 and a fifth capacitor element C5, the second path portion 22 is provided with a third capacitive element C3, a fourth capacitive element C4 and a third resistive element R3 coupled to each other. The low frequency portion and the high frequency portion pass through the first and second passage portions 21, 22, respectively, in other words, the frequency in the middle will not pass, thereby achieving an improvement.

The high frequency cutoff device 1 is further provided with a first capacitive element C1 for stabilizing the sound effect signal. The fifth resistive element R5 and the second capacitive element C2 of the high-frequency cutoff device 1 are connected in series with each other, and a first contact 41 is disposed between the fifth resistive element R5 and the second capacitive element C2. The first and second resistive elements R1, R2 of the stripping device 2 are connected in series from the first contact 41, and the first and second resistive elements R1, R2 have a second contact 42; The third and fourth capacitive elements C3 and C4 connected in series are connected to the first The first and second resistive elements R1, R2, and the third and fourth capacitive elements C3, C4 have a third contact 43; one end of the fifth capacitive element C5 and one end of the third resistive element R3 are respectively The second contact 42 and the third contact 43 are connected in parallel, and the other end is coupled between the second capacitive element C2 and the second resistive element R2 (as shown, the resistive The second resistive element R2 of the device 2 is further coupled to the signal amplifying device 3 via a sixth capacitive component C6 and a fourth resistive component R4. Therefore, one end of the fifth capacitive component C5 and the third resistive component The other end of R3 is coupled between the second capacitive element C2 and the fourth resistive element R4.
