Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a Bluetooth headset with a steel strip connecting the sound channels. Background Technology

[0002] Over-ear Bluetooth headphones typically include a headband, left and right earphone units 12 (including speakers) connected to both ends of the headband, and a mainboard (used for processing audio signals and enabling wireless connectivity) located within the headband or earphone units. To achieve the electrical connection (transmission of audio signals, i.e., positive and negative polarity connection) between the mainboard and the left and right speakers, traditional technology commonly uses two wires as the conductive medium. One end of the wire is connected to the mainboard, and the other end is connected to the positive and negative terminals of the left and right speakers, respectively, to transmit audio signals from the mainboard to the speakers on both sides.

[0003] However, traditional wire connection methods have the following drawbacks: the wire material is relatively soft, and during the use of headphones, the headband needs to be bent and stretched frequently to adapt to different users' head circumferences. The wire is under dynamic stress for a long time, which can easily lead to problems such as breakage and aging, affecting the service life and reliability of the headphones.

[0004] Furthermore, the wires inside the headphones require complex wiring and fixing, which increases the complexity of the assembly process and raises production costs.

[0005] Therefore, there is an urgent need to design a Bluetooth headset with a steel bar connecting the sound channels to solve one or more technical problems that are lacking in the existing technology. Summary of the Invention

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a Bluetooth headset with a steel bar connecting the sound channels, comprising: a headband assembly, a left earphone unit, a right earphone unit, and a main board; both the left earphone unit and the right earphone unit are equipped with speakers; characterized in that the headband assembly includes a first steel bar, a second steel bar, a first support member, and a second support member, the first steel bar and the first support member are electrically connected to form a first conductive path, the second steel bar and the second support member are electrically connected to form a second conductive path; one end of the first conductive path is electrically connected to one electrode of the main board, the other end of the first conductive path is electrically connected to the corresponding electrode of the left earphone unit and / or the right earphone unit, one end of the second conductive path is electrically connected to the other electrode of the main board, and the other end of the second conductive path is electrically connected to the corresponding electrode of the left earphone unit and / or the right earphone unit.

[0008] In a preferred embodiment, the headband assembly further includes an insulating wrapping, wherein the first steel bar, the second steel bar, the first support member, and the second support member are all located within the insulating wrapping, and the insulating wrapping is bent at a predetermined curvature.

[0009] In a preferred embodiment, the headband assembly further includes: a third steel bar, a fourth steel bar, a third support member, and a fourth support member. The third steel bar and the third support member are electrically connected to form a third conductive path, and the fourth steel bar and the fourth support member are electrically connected to form a fourth conductive path. One end of the third conductive path is electrically connected to one of the electrodes of the main board, and the other end of the third conductive path is electrically connected to the corresponding electrode of the right earphone unit / the left earphone unit. One end of the fourth conductive path is electrically connected to the other electrode of the main board, and the other end of the fourth conductive path is electrically connected to the corresponding electrode of the right earphone unit / the left earphone unit.

[0010] In a preferred embodiment, the first support member, the second support member, the third support member, and the fourth support member are made of metal or non-metallic materials with a conductive layer on their surface.

[0011] The beneficial effects of this utility model are as follows: This application replaces the traditional wire connection method with the first and second steel bars, which effectively avoids the head beam from being frequently bent and easily broken under tension, significantly improving service life and reliability. At the same time, the steel bars have both support and conductivity, eliminating the need for additional wires, reducing the complexity of internal wiring, lowering assembly difficulty, and improving production efficiency.

[0021] like Figures 1-2 As shown, this utility model provides a Bluetooth headset with a steel bar connecting the sound channels, including: a headband assembly 10, a left earphone unit 11, a right earphone unit 12, and a main board (not shown in the figure); both the left earphone unit 11 and the right earphone unit 12 are equipped with speakers; the headband assembly 10 includes a first steel bar 13, a second steel bar 14, a first support member 15, and a second support member 16, the first steel bar 13 and the first support member 15 are electrically connected to form a first conductive path, the second steel bar 14 and the second support member 16 are electrically connected to form a second conductive path; one end of the first conductive path is electrically connected to one of the poles of the main board, and the other end of the first conductive path is electrically connected to the corresponding pole of the left earphone unit 11 and / or the right earphone unit 12; one end of the second conductive path is electrically connected to the other pole of the main board, and the other end of the second conductive path is electrically connected to the corresponding pole of the left earphone unit 11 and / or the right earphone unit 12;

[0022] Specifically, the first steel strip 13 and the second steel strip 14 are made of stainless steel with a diameter of 1.5mm, giving them good conductivity and toughness; the first support member 15 and the second support member 16 are preferably made of aluminum alloy, which is conductive and lightweight. The first steel strip 13 is electrically connected to the first support member 15, and the second steel strip 14 is electrically connected to the second support member 16, forming a first conductive path between the first steel strip 13 and the first support member 15, and a second conductive path between the second steel strip 14 and the second support member 16. One end of the first conductive path is connected to the positive terminal of the main board, and the other end of the first conductive path is connected to the speaker in the left earphone unit 11. The positive terminal of the speaker is connected; one end of the second conductive path is connected to the negative terminal of the motherboard, and the other end of the second conductive path is connected to the negative terminal of the speaker in the left earphone unit 11, forming a positive terminal of the motherboard → a positive terminal of the first conductive path → a positive terminal of the left earphone unit 11, and a negative terminal of the left earphone unit 11 → a negative terminal of the second conductive path → a negative terminal of the motherboard. When the motherboard outputs an audio signal, the audio signal is transmitted into the left earphone unit 11 through the first conductive path and returns to the motherboard from the negative terminal of the left earphone unit 11, realizing the left channel sound output; in order to reduce contact resistance, gold-plated conductive terminals are provided at the connection points of the first and second conductive paths with the motherboard and the left earphone unit 11.

[0023] The connection of the right earphone unit 12 is similar. By setting the third steel bar (not shown in the figure), the fourth steel bar (not shown in the figure), the third support (not shown in the figure), and the fourth support (not shown in the figure), a third conductive path and a fourth conductive path are formed, connecting the motherboard and the right earphone unit 12 to realize the right channel output.

[0024] In another embodiment, one end of the first conductive path can be connected to the positive terminal of the left earphone unit 11, and the other end can be connected to the positive terminal of the right earphone unit 12. It is then connected to the positive terminal of the motherboard through wires or the like. One end of the second conductive path is connected to the negative terminal of the left earphone unit 11, and the other end is connected to the negative terminal of the right earphone unit 12. It is then connected to the negative terminal of the motherboard through wires or the like, forming a parallel circuit.

[0025] Furthermore, the first steel bar 13 and the first support member 15, and the second steel bar 14 and the second support member 16 can be connected by welding, riveting, or by conductive connectors. The conductive connectors can be conductive bolts or conductive adhesives, etc. In this embodiment, spot welding is preferred to ensure the connection is firm and conductive.

[0026] Furthermore, the headband assembly 10 also includes an insulating wrapping component made of flexible insulating material, used to wrap the first steel bar 13, the second steel bar 14, the first support member 15, and the second support member 16, to avoid direct contact with the user's head and to improve wearing comfort.

[0027] Furthermore, the first support member 15, the second support member 16, the third support member, and the fourth support member can be made of metal, preferably aluminum alloy or non-metallic material with a conductive layer on the surface. The non-metallic material needs to have a certain supporting capacity to cooperate with the support of the steel bar lifting head beam.

[0028] In summary, this application replaces the traditional wire connection method with the first steel bar 13 and the second steel bar 14, effectively avoiding frequent bending of the head beam and easy breakage under tension, significantly improving service life and reliability. At the same time, the steel bars have both support and conductivity, eliminating the need for additional wires, reducing the complexity of internal wiring, lowering assembly difficulty, and improving production efficiency. Furthermore, the conductivity of the steel bars is stable and less affected by environmental factors (such as temperature and humidity), ensuring stable transmission of audio signals.

[0029] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
