Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and more specifically, to a bass-enhanced Bluetooth headset. Background Technology

[0002] Bluetooth is a widely used wireless communication technology. It is a special short-range wireless technology that establishes a communication environment for fixed and mobile devices based on low-cost short-range wireless connections. Using Bluetooth technology, communication between mobile terminal devices can be effectively simplified. In recent years, Bluetooth technology has been increasingly used in the headphone field to replace the mode of wired headphones being directly connected to audio source devices, thereby improving their ease of use.

[0003] Due to size constraints, existing Bluetooth headphones have a very small sound-producing volume and a small diaphragm vibration amplitude, resulting in compromised bass performance. Furthermore, since the sound enters the ear directly, it's difficult to modify or improve the bass response. Therefore, in practical applications, due to technological and cost limitations, a balance between sound quality and price must be achieved by sacrificing some aspects, significantly impacting the overall sound quality of existing headphones.

[0004] Therefore, how to enhance the bass sound quality has become an urgent problem to be solved in the field of Bluetooth headphone technology. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, such as reduced bass sound quality due to the limited sound-emitting space of Bluetooth headphones.

[0007] A bass-enhanced Bluetooth headset includes a headset body, the headset body including a fitting part and a sound-emitting part;

[0008] The sound outlet of the sound-emitting part is located on the side near the fitting part and faces the human ear;

[0009] The sound-emitting part is provided with a sound outlet cavity, which is connected to the sound outlet. A bass-enhancing slope is provided in the sound outlet cavity, and the bass-enhancing slope extends to the sound outlet.

[0010] Furthermore, there is an angle between the bass-enhancing slope and the axis of the sound outlet, and the angle between the bass-enhancing slope and the axis of the sound outlet is 20°.

Semi-encircling ear hooks are provided at the connection points between the neckband connecting cable and the first headphone body and the second headphone body. The semi-encircling ear hooks are all flipped towards the center line of the neckband connecting cable.

[0012] The first and second earphone bodies have the same structure.

[0013] Furthermore, the first earphone body also includes a connection terminal, which is electrically connected to the neckband connection cable;

[0014] The sound-generating part is provided with a sound-generating unit, and the bonding part is provided with a capacitor sheet;

[0015] The fitting part and the sound-emitting part overlap and are fixed together, but are partially offset.

[0016] Furthermore, the sound-generating part includes an outer shell, and the outer shell has a top cover on the side opposite to the fitting part. The top cover has a through hole in the center and a dust cover that can completely cover the through hole.

Detailed Implementation

[0032] 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, 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.

[0033] 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.

[0034] Example:

[0035] Please refer to Figures 1-6 As shown.

[0036] This application provides a bass-enhanced Bluetooth headset, including a headset body, the headset body including a fitting part 41 and a sound-emitting part 42;

[0037] 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;

[0038] The sound-emitting part 42 is provided with a sound outlet cavity 429, which is connected to the sound outlet 428. The sound outlet cavity 429 is provided with a bass enhancement slope 426, which extends to the sound outlet 428.

[0039] Currently, Bluetooth headphones are mainly divided into several types: in-ear, semi-in-ear, ear-hook, and speakerphone. However, in-ear and semi-in-ear headphones can cause ear damage when worn for a long time. Therefore, in order to protect the ears, ear-hook and speakerphone headphones are usually used to reduce the damage to the ears.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] Furthermore, there is an angle between the bass enhancement slope 426 and the axis of the sound outlet 428, and the angle between the bass enhancement slope 426 and the axis of the sound outlet 428 is 20°.

[0046] 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.

[0047] 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.

[0048] The first earphone body 4 and the second earphone body 6 have the same structure.

[0049] 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.

[0050] 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.

[0051] Furthermore, the first earphone body 4 also includes a connection end 43, which is electrically connected to the neckband connection cable 1;

[0052] 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.

[0053] The fitting part 41 and the sound-emitting part 42 are overlapped and fixed, and partially offset.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] Furthermore, the sound-generating part 42 includes an outer shell 421, and an upper cover 423 is provided on the side of the outer shell 421 away from the fitting part 41. The upper cover 423 has a through hole 427 in the center, and a dust cover 422 is provided on the upper cover 423 that can completely cover the through hole 427.

[0060] In this embodiment, the outer casing 421 is used to house the sound-emitting unit 44 and provide space for sound quality improvement after the sound-emitting unit 44 emits sound. The upper cover 423 and the through hole 427 on the upper cover 423 can allow air to enter into the outer casing 421, thereby enabling the sound-emitting unit 44 to emit sound waves smoothly.

[0061] 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.

[0062] 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.

[0063] Furthermore, the bonding portion 41 includes an electronic housing 413, which contains a circuit board 45 and a battery 46.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] Furthermore, a buckle 2 is fitted onto the neck strap connecting line 1, and a storage box 3 is fixed onto the buckle 2.

[0070] 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-emitting space for the earphone body, allowing the sound output cavity 429 to output better sound quality.

[0071] 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. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
