Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of Bluetooth headsets, and more specifically, particularly relates to a Bluetooth headset with an external antenna. Background Art
[0002] The antennas of existing Bluetooth headsets are all set inside the headset shell. An antenna transceiver component is set on the PCBA of the headset or a spring is used to contact the copper foil attached to the inside of the headset shell. Since the internal space of the headset shell is small and there are many other components that affect the antenna performance, especially for ear clip Bluetooth headsets, the PCBA and the headset shell will be blocked by the ear, resulting in an antenna blind area. The shielding of the headset antenna causes the connection between the headset and the mobile phone to become stuck and disconnected.
[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a Bluetooth headset with an external antenna is provided, in order to achieve a more practical purpose. Summary of the invention
[0004] In order to solve the above technical problems, the present invention provides a Bluetooth headset with an external antenna, which is achieved by the following specific technical means: A Bluetooth headset with an external antenna comprises a PCBA fixed shell and an earphone speaker fixed shell, wherein the PCBA fixed shell and the earphone speaker fixed shell are connected via a connector, a PCBA is fixedly installed inside the PCBA fixed shell, an antenna port is provided on one side of the PCBA, and a metal wire is connected to one side of the antenna port, and the other end of the metal wire extends to the inside of the connector.
[0005] Furthermore, connectors are fixedly installed on the top sides of the PCBA fixed housing and the headphone speaker fixed housing, and the connectors are fixedly connected to both ends of the connector respectively.
[0006] Furthermore, an inner support member is connected between the two groups of joints, and the inner support member is arranged inside the connecting member.
[0007] Furthermore, the connecting piece and the inner supporting piece are both made of silicone.
[0008] Furthermore, the bottom side of the joint is provided with a through hole communicating with the upper end thereof, and the interior of the inner support is provided with a mounting hole for accommodating the metal wire, and one end of the mounting hole is communicated with the through hole.
[0009] Furthermore, a speaker is fixedly installed inside the earphone speaker fixing shell, a wire is connected between the speaker and the PCBA, and the main body of the wire is arranged inside the connector.
[0010] Compared with the prior art, the present invention has the following beneficial effects: The present invention utilizes a metal wire to connect with the antenna port on the PCBA, and arranges the metal wire inside the connector to replace the existing antenna structure. The metal wire can be completely exposed outside the ear, and can better receive the signal sent back by the mobile phone and feed it back to the headset, which can effectively improve the receiving performance and is less likely to cause the headset and the mobile phone to be blocked by the ear. The connection is stuck and disconnected; at the same time, the metal wire is arranged inside the connector, which can improve the performance of the headset antenna without changing the product size and appearance, and can effectively reduce the size of the headset body.
