Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example:

[0039] Please refer to Figures 1-6 As shown.

[0040] This application provides a Bluetooth headset with an integrated sound cavity, including a headset body, the headset body including a fitting part 41 and a sound-emitting part 42;

[0041] The sound outlet 428 of the sound-emitting part 42 is located on the side near the fitting part 41 and faces the human ear;

[0042] The sound-emitting part 42 is provided with a sound outlet cavity 429, which is connected to the sound outlet 428. The sound-emitting part 42 includes an outer shell 421, and the outer shell 421 is provided with a top cover 423 on the side opposite to the fitting part 41.

[0043] The outer shell 421 and the sound outlet cavity 429 are integrally formed.

[0044] Currently, in existing technologies, for ease of production, the main body of the earphone usually contains many spliced ​​parts, including the sound outlet cavity 429 and the outer shell 421, which are all spliced ​​together. This results in many gaps between the parts, which leads to sound leakage. When sound leakage occurs, there is not only a risk of privacy leakage, but it also affects the sound effect, thus greatly affecting the audio-visual experience.

[0045] In this embodiment, sound is output through the sound cavity 429 and the sound outlet 428. Therefore, the optimal way to output sound is to converge it and output it through the sound outlet 428. This embodiment uses a one-piece molded outer shell 421 and sound cavity 429, thereby reducing the gaps between parts within the sound outlet 428. With fewer gaps, sound waves will not leak out, thus ensuring the integrity of sound wave transmission. There is no splicing operation between the one-piece molded outer shell 421 and the sound cavity 429, so there is no interaction force between components, which can reduce wear between components during wear and improve the service life of this embodiment to a certain extent. The one-piece molded outer shell 421 and sound cavity 429 also have better mechanical properties, thereby improving the impact resistance of this embodiment.

[0046] In summary, this embodiment can ensure that the sound outlet cavity 429 does not leak sound, and can also ensure the overall stability of the headphone body and increase the service life of the headphone body.

[0047] Furthermore, a bass-enhancing slope 426 is provided in the sound outlet cavity 429, the bass-enhancing slope 426 extends to the sound outlet 428, and there is an angle between the bass-enhancing slope 426 and the axis of the sound outlet 428, the angle between the bass-enhancing slope 426 and the axis of the sound outlet 428 is 20°.

[0048] Because the sound-producing section of the headphone housing has limited space (42), the ventilation in the rear cavity is easily reduced or eliminated. This increases the acoustic impedance of the rear cavity, reducing the amplitude of the speaker diaphragm's vertical vibration. The most direct impact is a reduction in the low-frequency components of the sound, making the headphone sound thin and deteriorating the overall subjective experience. Current industry solutions often use dynamic equalizers with added EQ or virtual bass with added harmonic components to compensate for the leaked bass. However, this does not directly solve the problem of the low proportion of bass in the headphone's sound; in fact, it may create a risk of disharmonious audio proportions.

[0049] While directly increasing the output power of the headphone body may result in more bass output, the treble output can easily be adjusted to a level that can damage the ears.

[0050] This embodiment improves the problem of insufficient bass content by setting a bass-enhancing slope 426, which utilizes the reflection and loss of high frequencies and the preservation of low frequencies.

[0051] In this embodiment, the sound-emitting part 42 emits sound, and the emitted sound waves include long waves and short waves. The high-frequency wavelength is short and the low-frequency wavelength is long. As a result, the sound waves will be reflected and cancel each other out in the sound outlet cavity 429. By setting the bass enhancement slope 426, the high frequencies are consumed more in the sound outlet cavity 429, thereby enhancing the release rate of the short waves and achieving the purpose of enhancing the bass effect.

[0052] In this embodiment, the bass-enhancing slope 426 in the sound outlet cavity 429 has the function of having no effect on bass and reflecting and dissipating treble, so that the sound-emitting part 42 can emit a reasonable ratio of treble and bass, thereby enhancing the sound quality. When the output power of the headphone body is increased, there will not be excessive treble output. By adjusting the amount of treble, the goal of both obtaining clear bass and protecting the human ear can be achieved.

[0053] In this embodiment, the angle of the bass enhancement slope 426 is set to 20°, which can better preserve the wavelength of the bass range and consume the wavelength of the treble: the bass can be emitted directly from the sound outlet 428, and the treble will be continuously reflected in the sound outlet cavity 429, thereby canceling each other out.

[0054] Furthermore, it also includes a neckband connecting line 1. The headphone body includes a first headphone body and a second headphone body. One end of the neckband connecting line 1 is connected to the first headphone body 4, and the other end is connected to the second headphone body 6. The neckband connecting line 1 is provided with a semi-encircling ear hook 8 at the connection points with the first headphone body 4 and the second headphone body 6. The semi-encircling ear hook 8 is flipped towards the center line of the neckband connecting line 1.

[0055] The first earphone body 4 and the second earphone body 6 have the same structure.

[0056] In this embodiment, by setting up the first earphone body 4 and the second earphone body 6, the user can wear earphones on both sides at the same time, thereby enabling the user to effectively use stereo playback.

[0057] In this embodiment, the semi-circular ear hook 8 is used to fit the outer ear auricle under force. The semi-circular ear hook 8 is rotated towards the center line of the neck hook connecting line 1, so that the semi-circular ear hook 8 can more effectively fit the changes in head shape and avoid the semi-circular ear hook 8 from warping when worn on the ear.

[0058] Furthermore, the first earphone body 4 also includes a connection end 43, which is electrically connected to the neckband connection cable 1;

[0059] The sound-emitting part 42 is provided with a sound-emitting unit 44, and the bonding part 41 is provided with a capacitor sheet 412.

[0060] The fitting part 41 and the sound-emitting part 42 overlap and are fixed together, but are partially offset.

[0061] The outer casing 421 is used to house the sound-emitting unit 44 and to provide space for sound quality improvement after the sound-emitting unit 44 emits sound.

[0062] In this embodiment, the connecting end 43 is located outside the fitting part. The connecting end 43 connects the first earphone body 4 and the second earphone body 6 to the neckband connecting cable 1, thereby achieving the purpose of synchronous operation of the two. Furthermore, the external connecting end 43 can improve the center of gravity position of the first earphone body 4 by adding counterweight in the direction away from the ear, thereby improving the user's wearing comfort by avoiding the first earphone body 4 pressing on the human skin.

[0063] Because ear-hook headphones don't fit snugly against the ears and lack a locking mechanism to prevent slipping, traditional ear-hook Bluetooth headphones offer a poor user experience and suffer from significant sound leakage. Meanwhile, headphones with external speakers pose a serious privacy risk due to their external speaker design.

[0064] In this embodiment, the neckband connection cable 1 is used to increase the force points of the headphones, thereby making the overall wearing of this embodiment more stable. The sound-emitting part 42 and the fitting part 41 are partially staggered, so that the sound outlet 428 can be aligned with the human ear.

[0065] When the sound-emitting part 42 emits sound, it can effectively emit sound from the staggered part. The fitting part 41 is close to the human body, and the sound-emitting part 42 is far away from the human body, so that the sound-emitting part 42 is not restricted by the human body structure and can have more space to improve the sound quality.

[0066] In this embodiment, since the fitting part 41 is relatively close to the ear and the sound-emitting part 42 is relatively far from the ear, this embodiment can use the fitting part 41 as a limiting mechanism to restrict the relative position of the sound outlet 428 and the ear, thereby achieving the purpose of effectively aligning the sound outlet 428 with the ear. To a certain extent, this can more effectively avoid the problem of sound leakage. Since the fitting part 41 is not restricted by the sound-emitting operation, it can be shaped to fit the ear without affecting the sound quality, thus enabling this embodiment to obtain better sound quality and better wearing comfort.

[0067] Furthermore, the bonding portion 41 includes an electronic housing 413, which contains a circuit board 45 and a battery 46.

[0068] The capacitor sheet 412 is located on the outer surface of the electronic housing 413. A bonding pad 411 is also provided on one side of the capacitor sheet 412. The capacitor sheet 412 is electrically connected to the circuit board 45.

[0069] In this embodiment, the electronic housing 413 of the fitting part is used to accommodate the circuit board 45 and the battery 46, and can increase the fit between the sound outlet 428 and the human ear by conforming to the human body, thereby avoiding sound leakage to a certain extent.

[0070] In this embodiment, the use of a fitting pad 411 makes the contact between the fitting part 41 and the human body more comfortable. Furthermore, the use of a capacitor pad 412 effectively utilizes the change in capacitance of the capacitor pad 412 caused by the human body's resistance to identify the wearing status, thereby enabling timely detection when the first earphone body 4 and the second earphone body 6 are removed.

[0071] Furthermore, the second earphone body 6 is equipped with a microphone 5 and an external charging connection unit 7. The microphone 5 faces away from the neckband connection cable 1, and the external charging connection unit 7 faces the side closer to the neckband connection cable 1.

[0072] In this embodiment, a headset 5 and an external charging connection unit 7 are provided on the second earphone body 6 to facilitate calls and charging. In this embodiment, both the headset 5 and the external charging connection unit 7 are models that can be configured on a large scale using existing technology, which facilitates mass production of this embodiment.

[0073] Furthermore, a buckle 2 is fitted onto the neck strap connecting line 1, and a storage box 3 is fixed onto the buckle 2.

[0074] In this embodiment, the storage box 3 is fixed using the snap-fit ​​2. The storage box 3 is used to store the 2.4GHz receiver, thereby improving the Bluetooth connection efficiency of this embodiment. The snap-fit ​​2 structure facilitates the disassembly, assembly, and position adjustment of the storage box 3, and also facilitates maintenance of the Bluetooth connection module. Simultaneously, the external receiver provides more sound output space for the earphone body, allowing the sound outlet cavity 429 to output better sound quality.

[0075] Furthermore, the upper cover 423 has a through hole 427 in the center, and the upper cover 423 is provided with a dust cover 422 that can completely cover the through hole 427.

[0076] The top cover 423 and the through hole 427 on the top cover 423 allow air to enter the outer shell 421, thereby enabling the sound-emitting unit 44 to emit sound waves smoothly. The dust cover can effectively prevent dust from entering the headphone body.

[0077] Furthermore, a transition connection portion 425 is provided at the connection between the outer shell 421 and the fitting portion 41, and the transition connection portion 425 has an arc surface structure.

[0078] In this embodiment, the transition connection part 425 uses an arc-shaped structure to make the connection between the outer shell 421 and the fitting part 41 smooth, thus avoiding local squeezing injury to the human body when wearing the first earphone body 4.

[0079] Furthermore, a slope 424 is provided between the outer shell 421 and the upper cover 423, and the angle between the surface of the slope 424 and the upper cover 423 is an acute angle;

[0080] The outer casing 421 is provided with a fixing seat 4210. One side of the fixing seat 4210 is connected to the sound-generating unit 44, and the other side is inserted into the through hole 427.

[0081] A fitting structure 4211 is provided between the upper cover 423 and the outer shell 421, and the upper cover 423 and the outer shell 421 are detachably and fixedly connected through the fitting structure 4211.

[0082] A slope 424 is provided between the outer shell 421 and the upper cover 423, and the angle between the surface of the slope 424 and the upper cover 423 is an acute angle;

[0083] The outer casing 421 is provided with a fixing seat 4210. One side of the fixing seat 4210 is connected to the sound-generating unit 44, and the other side is inserted into the through hole 427.

[0084] A fitting structure 4211 is provided between the upper cover 423 and the outer shell 421, and the upper cover 423 and the outer shell 421 are detachably and fixedly connected through the fitting structure 4211.

[0085] In this embodiment, the slope 424 can effectively avoid damage from the squeezing of sharp edges and provide better vibration space for the sound-generating unit 44.

[0086] In this embodiment, the fixing base 4210 can effectively utilize the through hole 427 as a force point, thereby making the force on the sound generating unit 44 more balanced, thus improving the sound quality of the vibration sound generation.

[0087] In this embodiment, the fixing base 4210 can also effectively ensure the unobstructed flow of the through hole 427, so that enough air can be taken into the outer shell 421 for vibration and sound generation.

[0088] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
