[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model discloses an integrated side-emitting speaker module for both high and low frequencies, comprising a panel 1. The panel 1 includes an inner cavity located on the inner side and an outer cavity located on the outer side. The inner cavity is filled with N-bass powder 2, and the surface of the N-bass powder 2 is covered with an N-bass powder mesh 3. A woofer 4 and a tweeter 5 are also installed in the inner cavity. The woofer 4 is a speaker driver specifically designed for playing low frequencies, and the tweeter 5 is a speaker driver specifically designed for playing high frequencies. The outer cavity consists of a front woofer cavity 1-1 and a rear woofer cavity 1-2. A woofer steel plate 6 and a woofer steel plate mesh 7 are disposed through the front woofer cavity 1-1 and the rear woofer cavity 1-2. The woofer steel plate 6 is located outside the woofer steel plate mesh 7, which is used to adjust the bass response and prevent air leakage. A sound outlet 8 is provided on the front cavity 1-1 of the bass driver. A tweeter 9 is also installed inside the front cavity 1-1 of the bass driver. The tweeter 9 is arranged parallel to the bass driver 6 and is adjacent to the sound outlet 8. A back plate 10 is also installed on the inner side of the panel 1, covering the N-bass mesh 3, the bass driver 4, and the tweeter 5. The function of the bass driver 6 and the tweeter 9 is to increase the space of the outer cavity of the panel, that is, to seal the cavity and facilitate the sound output of the high and low frequencies.

[0019] The tweeter and woofer share the same woofer front cavity 1-1, with the tweeter steel plate 4 installed inside the woofer front cavity 1-1, saving space in the final product. The woofer steel plate 6 has several through holes 6-1, which effectively improves sound quality and heat dissipation of the internal tweeter module.

[0020] The size of the bass plate 6 is larger than that of the tweeter plate 9. The large size of the bass plate 6 is designed to match the physical characteristics of low-frequency sound waves and ensure sufficient air thrust and sound pressure. The small size of the tweeter plate 9 is designed to adapt to the rapid vibration and precise control of high frequencies. The division of labor between the bass plate 6 and the tweeter plate 9 enables the speaker to reproduce sound across the entire frequency range.

[0021] A vent pad 11 corresponding to the woofer 4 is installed on the back plate 10, which serves to prevent air leakage. Similarly, a damping mesh 12 corresponding to the tweeter 5 is installed on the back plate 10, which also serves to prevent air leakage. Preventing air leakage is crucial for ensuring the acoustic performance, sound fidelity, and mechanical reliability of the speaker module; the seal directly affects the accuracy, dynamic range, and overall listening experience.

[0022] The N-bass powder mesh 3, bass resonator mesh 7, and damping mesh 12 all have numerous tiny holes and can be made of knitted yarn or similar materials. The bass resonator mesh 7 and damping mesh 12 reduce external noise and interference, improving sound quality by filtering out some sharp noises, resulting in a purer and clearer sound. The N-bass powder mesh 3 prevents the N-bass powder 2 from spilling out of the panel's internal cavity, thus preventing it from being blown away by wind during speaker operation. This ensures the N-bass powder 2 remains inside the speaker module and does not scatter due to vibration or airflow, thereby guaranteeing the normal operation of the speaker module.

[0023] The cavity inside the panel is filled with N-bass powder 2. The core purpose of filling with N-bass powder 2 is to optimize acoustic performance (reduce resonance, extend low frequencies) and improve heat dissipation / structural stability. Specifically, the reason for filling the cavity inside the panel with N-bass powder 2 is that when the speaker is working, the sound wave reflection inside the cavity inside the panel will form a standing wave, which will cause certain frequencies to be enhanced or canceled (especially low frequencies), resulting in distortion. Sound-absorbing materials such as N-bass powder 2 convert sound energy into heat energy through porous structure or particle friction, reduce standing waves and cabinet resonance, and make the frequency response smoother. High-power speakers will generate heat when working for a long time. N-bass powder 2 can help dissipate heat and protect the voice coil and magnetic circuit.

[0024] This integrated high and low frequency side-emitting speaker module enhances the rigidity and heat dissipation performance of the module by adding a steel plate structure, while optimizing the separation of high and low frequencies to improve sound quality. The integrated high and low frequency design also saves space in the end product.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
