no. 1 example

[0039] like Figure 1 to Figure 3 As shown, the resonance sheet 12 has a center (not shown in the figure), and the iron core post 13 , the sound plate 14 , the voice coil 15 and the vibrator 16 are arranged on the resonance sheet 12 away from the center of the resonance sheet 12 . In this way, when the resonant sound 10 resonates, the side of the resonant sheet 12 where the iron core column 13 is located off the center will have a smaller vibration amplitude than the opposite side, and the high-pitched effect will be better.

[0040] Of course, the iron core post 13 , the sound plate 14 , the voice coil 15 and the vibrator 16 can also be arranged on the center of the resonance sheet 12 .

[0042] like Figure 4 and Figure 5 As shown, the sound cover 11b is provided with an air hole 112b for communicating with the outside and the resonance cavity 111b, and an air duct 113b for enhancing gas resonance extends inward from the hole wall of the air hole 112b. When the resonant cavity 111b resonates, the resonant gas inside it will convect with the outside through the air duct 113b and the air hole 112b, so that the resonance frequency of the resonant cavity 111b will be changed. Therefore, by adjusting the aperture size of the air hole 112b, or adjusting The length of the body of the air duct 113b is used to adjust the resonance frequency of the resonant cavity 111b, thereby increasing the mid-frequency and mid-low frequency.

[0043] finely, as Figure 4 and Figure 5 As shown, the resonance cavity 111b includes a left cavity 1111b and a right cavity 1112b, the iron core column 13b, the sound plate 14b, the voice coil 15b and the vibrator 16b are arranged in the r...

[0046] like Image 6 and Figure 7 As shown, the sound cover 11c is provided with a first through groove 112c, and the first through groove 112c is provided with a diaphragm 113c for resonating with the sound cover 11c to enhance the mid-range and mid-bass. When the resonance cavity 111c resonates, the resonant gas inside will act on the diaphragm 113c to make the diaphragm 113c vibrate.

[0047] finely, as Image 6 and Figure 7 As shown, the resonance cavity 111c includes a left cavity 1111c and a right cavity 1112c, the iron core column 13c, the sound plate 14c, the voice coil 15c and the vibrator 16c are arranged in the right cavity 1112c, and the diaphragm 113c is arranged on the top of the sound cover 11 and located in the in the left cavity 1111c. Since the vibration amplitude of the resonance plate 12c located in the left cavity 1111c is larger than that of the resonance plate 12c located in the right cavity 1112c, the gas in the left cavity 1111c also has a larger...

Abstract

The invention relates to the technical field of acoustics, and provides resonant acoustics, comprising a sound cover with an inner cavity and an opening at one end, and a resonance sheet for covering the opening to form a closed resonance cavity in the inner cavity. A sound board is sleeved on the column, a voice coil is sleeved on the sound board, and a vibrator is sleeved on the voice coil. The soundboard and the voice coil are energized to cause the soundboard and the voice coil to vibrate back and forth in the magnetic field of the iron core column, so as to cause the vibrator to vibrate together, and transmit the vibration to the resonance chamber, and the resonance chamber transmits the vibration to the resonance sheet and the sound cover. , the resonant sheet vibrates and produces sound to improve high frequency; the sound cover and resonant cavity resonate sound to improve the intermediate frequency and low frequency; Improve sound quality. In short, the resonance sound has low consumption, high efficiency, high sound quality, high treble, mid-frequency and low-frequency effects.

Description

technical field [0001] The present invention belongs to the technical field of acoustics, and particularly relates to resonant acoustics. Background technique [0002] The known traditional sound is produced through the inductive coil and speaker set in the sound. The sound quality of this traditional sound is closely related to the speaker. The speaker is the only sound-emitting device in the sound, and its sound quality is fixed. The speaker cannot arbitrarily change the sound quality of the speaker. [0003] With the development of economy and technology, people's pursuit of sound quality is getting higher and higher. In recent years, resonance sound has appeared on the market. The existing resonance sound mainly uses active resonance speakers, which generally use a sticking structure, and adhere to any hard object in contact with it through the sticking structure, and use the principle of resonance to convert the audio frequency. The signal is converted into audio mech...
