Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a dual independent front cavity parallel module. Background Technology

[0002] As a rising star in sports audio equipment, the OWS clip-on earphones boast a sophisticated structural design that perfectly blends ergonomics and acoustic engineering. The core components, the first and second earpieces, precisely integrate high-resolution audio decoding chips and low-latency Bluetooth transmission modules, enabling not only lossless real-time sound reproduction but also stable audio transmission during vigorous exercise. The elastic bridge connecting the two earpieces is made of shape memory alloy with a built-in flexible circuit board, allowing for 180° free bending while ensuring stable audio signal transmission. Modular customizable components, such as anti-slip wings and a magnetic charging dock, can be replaced according to user needs, giving the product a high degree of personalization and adaptability.

[0003] In the consumer electronics industry, OWS clip-on headphones are facing a sharp contradiction between acoustic performance and size control. In pursuit of ultimate comfort, engineers have compressed the overall thickness to below 12mm, but this makes it difficult for traditional single speakers to provide sufficient low-frequency radiation space. Limited by the amplitude range of the miniature diaphragm, when playing electronic music or movie soundtracks, the originally powerful low-frequency effect is weakened into a thin hum, and the sound pressure level struggles to exceed 85dB, failing to meet the demand for powerful sound effects in action scenarios. Attempts to enhance low frequencies by connecting multiple speakers in parallel suffer from increased low-frequency distortion due to the close spacing between the miniature drivers and the interference of sound waves generated by different diaphragms within the confined space. Utility Model Content

[0004] The purpose of this invention is to provide a dual independent front cavity parallel module to solve the problems of phase resonance distortion and weak low-frequency response in the existing speaker structure.

[0005] To achieve the above objectives, this utility model provides a dual independent front cavity parallel module, including an upper speaker, a lower speaker, and a front cavity channel. The front cavity channel is disposed between the lower speaker and the upper speaker. A front cavity isolation plate is disposed between the upper speaker and the lower speaker. The front cavity isolation plate, the upper speaker, and the lower speaker are all connected to an external support member.

[0006] Preferably, the outer support member is made of plastic and is configured as a cylindrical structure.

[0007] Preferably, the cross-sections of the peripheral support members are all connected to the upper speaker and the lower speaker, and the lower speaker, the upper speaker, and the peripheral support members are all connected by adhesive sealing.

[0008] Preferably, the upper speaker and the lower speaker adopt a parallel acoustic path.

[0009] Preferably, the diaphragms of the upper speaker and the lower speaker are arranged opposite to each other and both face the front cavity isolation plate.

[0010] Preferably, the peripheral support member and the front cavity isolation plate are connected by an in-mold injection molded steel sheet.

[0011] Therefore, the present invention employs the above-mentioned dual independent front cavity parallel module, which has the following beneficial effects:

[0012] (1) By setting the front cavity isolation plate, the front cavity channel is divided into two independent cavities, eliminating acoustic interference and reducing distortion. The independent front cavity isolation diaphragm vibration effectively solves the problem of phase resonance distortion.

[0013] (2) By connecting the upper and lower speakers in parallel, the problem of insufficient sound pressure in small devices can be effectively solved, and the low-frequency response and overall volume can be significantly enhanced.

[0014] (3) By setting up the lower speaker, the problem of weak low-frequency sound is effectively improved, and the depth and elasticity of low frequency are improved.

[0015] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] Example

[0022] Please see Figure 1 This utility model provides a dual independent front cavity parallel module, including an upper speaker 1, a lower speaker 4, and a front cavity channel. The front cavity channel is located between the lower speaker 4 and the upper speaker 1. A front cavity isolation plate 3 is provided between the upper speaker 1 and the lower speaker 4, dividing the front cavity channel into two completely independent cavities, front cavity channel one 2 and front cavity channel two 6, which correspond to the upper speaker 1 and the lower speaker 4, respectively, realizing independent sound wave transmission paths and eliminating sound wave interference, thus reducing distortion. The front cavity isolation plate 3, the upper speaker 1, and the lower speaker 4 are all connected to the external support member 5.

[0023] The outer support component 5 is made of plastic and is designed as a beveled cylindrical structure with a trapezoidal cross-section. The shape of the outer support component 5 is not unique; it can also be a cylindrical structure with a rectangular cross-section. The outer support component 5 supports the upper speaker 1, the lower speaker 4, and the front cavity partition plate 3. The outer support component 5 is connected to the front cavity partition plate 3 via an in-mold injection-molded steel sheet. The outer support component 5 is installed between the front cavity partition plate 3 and the upper speaker 1, and between the lower speaker 4 and the front cavity partition plate 3. The lower speaker 4, the upper speaker 1, and the outer support component 5 are all sealed together with adhesive. The outer support component 5 is located outside the upper speaker 1 and the lower speaker 4, and its dimensions are larger than those of the upper speaker 1 and the lower speaker 4.

[0024] The bottom plane of the outer support member 5 is connected to the front cavity isolation plate 3. The oblique cut surfaces of the outer support member 5 are all connected to the upper speaker 1 and the lower speaker 4, so that the upper speaker 1 and the lower speaker 4 are set at an angle. The outer support member 5 fixes the upper speaker 1 and the lower speaker 4 in a facing arrangement. The diaphragm of the upper speaker 1 and the diaphragm of the lower speaker 4 are set opposite each other and both face the front cavity isolation plate 3, so that the diaphragms vibrate in opposite directions face to face, thereby optimizing the sound wave coupling efficiency.

[0025] The upper speaker 1 and the lower speaker 4 employ a parallel acoustic path to maximize sound pressure superposition efficiency, increasing sound pressure by 5dB. This significantly enhances low-frequency response and overall volume, solving the problem of insufficient sound pressure in small devices. The upper speaker 1 is responsible for full-range output, while the lower speaker 4, a dynamic driver unit, is responsible for full-range, multi-focused low-frequency enhancement. By focusing on low-frequency enhancement, the lower speaker 4 improves the depth and elasticity of low frequencies.

[0026] Therefore, this utility model adopts the aforementioned dual independent front cavity parallel module. Through the setting of the front cavity isolation plate, the front cavity channel is divided into two independent cavities, eliminating sound wave interference, reducing distortion, and effectively solving the problem of phase resonance distortion by isolating the diaphragm vibration in the independent front cavities. The parallel arrangement of the upper and lower speakers effectively solves the problem of insufficient sound pressure in small devices, significantly enhancing low-frequency response and overall volume. The lower speaker effectively improves the problem of weak low-frequency sound, improving low-frequency depth and elasticity.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
