In an alternative embodiment, the diameter of the hole structure 231 is equal to the diameter of the through hole 211, so that each hole structure 231 on the dome 23 of the back sound chamber can communicate with the front sound chamber through the through hole 211, and the ventilation amount of the diaphragm 20 is ensured, i.e. the air flow between the front sound chamber and the back sound chamber can be ensured to flow back and forth through the air holes 231 and the channel formed by the through holes 211.
In an alternative embodiment, the diameter of the hole structure 231 or the through hole 211 is 0.1 to 0.3 mm; and/or the number of the hole structures 231 or the through holes 211 in each row is 12, so as to meet the performance requirement of the loudspeaker on the sound film 21 in the vibration sound production process. The diameter and the number of the hole structures 231 or the through holes 211 may also be equal to other values, and may be specifically set according to the width and the length of the sound film 21 and the performance requirements of the sound film 21.
In an alternative embodiment, the sound membrane 21 is provided with a folded ring part 214 which is formed by being recessed from the surface connected with the dome 23 to a direction away from the dome 23, and the through hole 211 is provided on the mounting part 212 inside the folded ring part 214, so that the vibration of the air in the rear sound chamber can be responded to more rapidly, and the bass quality of the loudspeaker is improved.
The sound membrane 21 includes a fixing portion 213, an installation portion 212, and the above-mentioned ring-folding portion 214, the installation portion 212 is connected to the fixing portion 213 through the ring-folding portion 214, and the fixing portion is fixedly connected to the frame 10. Wherein, the dome 23 is attached to the mounting portion of the sound film 21.
In an alternative embodiment, the waterproof breathable film 22 is adhered to the through hole 211 of the mounting portion 212 by the adhesive layer 221.
In an alternative embodiment, the frame 10 includes a bottom frame 11 having the above-mentioned receiving space and a top cover 12 covering the opening of the receiving space, and the sound film 21 is fixed at the joint of the top cover 12 and the top cover 12 through the fixing portion 213, so that the bottom frame 11, the top cover 12 and the sound film 21 can enclose a sealed space to ensure the sealing property.
In an optional embodiment, the material for manufacturing the sound membrane 21 includes silica gel, rubber, PEEK, TPU and other high polymer materials, and the waterproof and breathable membrane includes a fabric layer, an adhesive layer and a waterproof and breathable layer, which are sequentially bonded and compositely connected. Wherein, waterproof ventilative layer is preferred to be the inflation polytetrafluoroethylene micropore thin film layer after the biaxial stretching is handled, inorganic filler particle forms the micropore with the plastic film base member junction of stereotyping at the biaxial stretching in-process, because the size of these micropores is sub-nanometer, the micropore aperture can be between 0.05 ~ 15 mu m, the air current of being convenient for can flow round trip through the micropore, and the micropore aperture size is not enough to let the hydrone pass through, play water-proof effects, not only avoided moisture to pass through the micropore and got into the cavity down, also prevented simultaneously that dust or metal powder from getting into the cavity down and influencing the sound quality of speaker through the micropore.
In summary, the following steps: during the operation of the speaker to generate sound, under the combined action of the varying current and the magnetic circuit system 40, the voice coil 30 drives the diaphragm 21 to vibrate, so that the air near the diaphragm 21 vibrates to generate sound, and during the vibration of the diaphragm 21, the front sound chamber and the rear sound chamber are isolated by the diaphragm 21. The pressure difference is generated due to the vibration of the sound diaphragm 21, which affects the performance of the speaker. Therefore, the dome 23 and the waterproof breathable film 22 are separately arranged on the upper side and the lower side of the sound film 21, so that the air permeability of the sound film 21 can be increased, the air flow between the front sound chamber and the rear sound chamber can be ensured to flow back and forth through the hole structure and the through holes, the pressure difference value between the front sound chamber and the rear sound chamber is reduced, namely the resistance force applied to the sound film 21 in the vibration process is reduced, and the tone quality and the stereo effect are improved. In addition, since the waterproof breathable film 22 is provided at the through hole, a waterproof function can be achieved.
