Description

Technical Field

[0001] The utility model relates to the technical field of wireless earphones, and specifically discloses a clip-on earphone with a metal appearance part as a Bluetooth antenna. Background Art

[0002] As a wireless communication technology, Bluetooth technology is widely used in various electronic devices, and earphones are one of the most common applications. The Bluetooth antenna of the earphone, as a key component for realizing wireless communication, is crucial for ensuring the stability and reliability of sound quality transmission. The design of the antenna directly affects the reception and transmission efficiency of Bluetooth signals, and thus affects the user experience.

[0003] Currently, the Bluetooth earphones on the market mainly adopt three types of antennas: on-board antennas, patch antennas, and laser-engraved antennas. The on-board antenna is an antenna directly installed on the PCB board. This design is simple but will increase the size of the PCB board, restricting the miniaturization design of the earphone. The patch antenna is a miniaturized antenna, usually installed on the outer shell of the earphone, but requires a certain clearance area to ensure performance, and when the human body is close, it may absorb some radio waves, affecting the Bluetooth connection effect. The laser-engraved antenna places the wire outside the shell, which has a greater impact on the appearance and requires additional multi-layer spraying processes for covering, resulting in higher costs.

[0004] In the design of existing clip-on earphones, due to their special shape and volume limitations, the current Bluetooth antenna design often has difficulty in balancing miniaturization and production costs while meeting the signal stability and transmission efficiency, so further improvement is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a clip-on earphone with a metal appearance part as a Bluetooth antenna.

[0006] The utility model discloses a clip-on earphone with a metal appearance part as a Bluetooth antenna, adopting the following technical scheme:

[0007] A clip-on earphone with a metal appearance part as a Bluetooth antenna, which includes a front cavity housing, a rear cavity housing, and a connecting bridge housing connected between the two. The connecting bridge housing includes a connecting bridge upper cover and a connecting bridge lower cover that are assembled and fixed. There is a cavity between the connecting bridge lower cover and the connecting bridge upper cover. The connecting bridge upper cover is farther from the human body than the connecting bridge lower cover. The connecting bridge upper cover is made of metal and serves as the radio frequency antenna for the Bluetooth function of the earphone.

[0008] Preferably, a speaker assembly is provided in the front cavity housing, and an electronic assembly including a PCB board, an earphone battery, and charging contacts is provided in the rear cavity housing.

[0009] Preferably, one end of the upper cover of the connection bridge close to the outer shell of the rear cavity is provided with an antenna contact, and the antenna contact is electrically connected to the PCB board.

[0010] Preferably, a connecting wire is connected between the front cavity outer shell and the rear cavity outer shell, and the connecting wire passes through the connection bridge housing and is arranged in the cavity.

[0011] Preferably, a wire groove for placing the connecting wire is provided inside the lower cover of the connection bridge.

[0012] Preferably, the upper cover of the connection bridge is provided with a male stop, and the lower cover of the connection bridge is provided with a female stop, and the male stop is assembled and fixed with the female stop.

[0013] Preferably, glue is applied for fixing between the male stop and the female stop.

[0014] Preferably, the upper cover of the connection bridge is arc-shaped or in other shapes.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] By arranging a connection bridge housing between the front cavity outer shell and the rear cavity outer shell and designing the upper cover of the connection bridge as a metal material, the upper cover of the connection bridge not only undertakes the function of decorating the outer shell of the earclip-type earphone, but also has the ability to transmit radio frequency signals, saving production costs. When a user wears such an earphone, since the upper cover of the connection bridge is located on the outer side of the human body, this helps to reduce the interference of the human body on the Bluetooth signal, thereby reducing signal loss and improving the stability and transmission efficiency of Bluetooth communication. In addition, by using the upper cover of the connection bridge as an external Bluetooth antenna, the cavity between the upper cover of the connection bridge and the lower cover of the connection bridge can be used as the clearance area required by the antenna. This not only optimizes the receiving performance of the radio frequency antenna, but also avoids the extra space required by the built-in antenna, making full use of the structure of the earphone connection bridge housing and helping to better achieve the miniaturization of the earphone design.

[0022] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0023] This embodiment discloses an earclip-type headphone with a metal appearance part as a Bluetooth antenna. Referring to Figures 1-3 , it includes a front cavity housing 1, a rear cavity housing 4, and a connection bridge housing connected between the two; a speaker assembly is installed in the front cavity housing 1 for emitting sound close to the human ear canal; an electronic assembly including a PCB board, a headphone battery, and a charging contact point is provided in the rear cavity housing 4 to be responsible for functions such as audio signal processing, power supply, and charging.

[0024] Among them, the connection bridge housing includes an upper cover 2 of the connection bridge and a lower cover 3 of the connection bridge that are assembled and fixed. There is a cavity 7 between the lower cover 3 of the connection bridge and the upper cover 2 of the connection bridge. The upper cover 2 of the connection bridge is farther from the human body than the lower cover 3 of the connection bridge. The upper cover 2 of the connection bridge is made of metal and serves as the radio frequency antenna for the Bluetooth function of the headphone. The upper cover 2 of the connection bridge is arc-shaped or other shapes. By setting the material of the upper cover 2 of the connection bridge to be a metal material, the upper cover 2 of the connection bridge not only serves as the housing appearance part of the earclip-type headphone, but also can be used to transmit radio frequency signals. When wearing the earclip-type headphone, since the upper cover 2 of the connection bridge is located in the area on the side without human body occlusion, it can effectively reduce the absorption of radio waves of the Bluetooth antenna by the human body, reduce the loss of Bluetooth signals, and is beneficial to the Bluetooth use effect. Moreover, since the upper cover 2 of the connection bridge is used as an external Bluetooth antenna, the cavity 7 formed between the upper cover 2 of the connection bridge and the lower cover 3 of the connection bridge can be used to provide the required clearance area for the radio frequency antenna, better ensuring the receiving sensitivity of the radio frequency antenna of the upper cover 2 of the connection bridge. Compared with the existing built-in antenna without the need to set an additional clearance area, the product volume of the headphone is effectively reduced, which is beneficial to the miniaturization of the headphone.

[0025] In this embodiment, the connection bridge housing can also be used to place the connecting wire 8. A connecting wire 8 is connected between the speaker assembly of the front cavity housing 1 and the electronic assembly of the rear cavity housing 4. The connecting wire 8 passes through the connection bridge housing and is arranged in the cavity 7. Specifically, a wire groove for placing the connecting wire can be provided in the lower cover 3 of the connection bridge to facilitate the better arrangement of the connecting wire 8 in the inner cavity of the connection bridge.

[0026] In this embodiment, an antenna contact 9 is provided at one end of the connection bridge upper cover 2 close to the rear cavity housing 4, and the antenna contact 9 is electrically connected to the PCB board. Specifically, the antenna contact 9 is part of the connection bridge upper cover 2. In other embodiments, the antenna contact 9 can also be replaced by a wire, and the wire connects the connection bridge upper cover 2 to the PCB board provided in the rear cavity housing 4 to form a loop.

[0027] In this embodiment, the connection bridge upper cover 2 is provided with a male stop 5, and the connection bridge lower cover 3 is provided with a female stop 6. The male stop 5 and the female stop 6 are assembled and fixed. As a further preferred solution, glue is applied between the male stop 5 and the female stop 6 to better ensure the connection stability between the connection bridge upper cover 2 and the connection bridge lower cover 3.
