Description

Technical Field

[0001] The utility model relates to the technical field of intelligent terminals, in particular to a combined installation device of a microphone and an antenna and a handheld intelligent terminal with the device. Background Art

[0002] With the increasing development of economy and technology, people's living standards have been continuously improved, and portable handheld intelligent terminals have become increasingly popular in people's lives and work.

[0003] As is well known, a handheld intelligent terminal needs to receive and send network signals and data through an antenna, and receive external sounds through a microphone and convert them into voice signals to ensure the normal operation of the network connection and voice interaction functions of the handheld intelligent terminal. Among them, in order to ensure the normal operation of the antenna, the area where the antenna is installed should be far from metal or metal parts (the distance between the antenna and metal or metal parts should be ensured to be more than 5 mm), and it cannot be directly attached to the metal. There needs to be a large clearance area between the antenna and nearby objects. Otherwise, it will be difficult to match the antenna, the radiation field will be distorted, and the antenna efficiency will also be reduced.

[0004] Therefore, not only should the antenna not be in contact with adjacent metal parts, but also a certain safety distance should be maintained. When assembling a handheld intelligent terminal, the antenna must be far from the microphone. Moreover, both the antenna and the microphone must be installed on the side wall of the handheld intelligent terminal housing, so that the antenna and the microphone need to be installed side by side with a horizontal gap on the housing of the handheld intelligent terminal, which requires a large amount of installation space. This not only affects the installation and layout of other components in the handheld intelligent terminal, increases the production cost, but also makes the volume of the handheld intelligent terminal need to be larger to meet the installation requirements, and it is difficult to meet the production and use requirements of the small and compact handheld intelligent terminal.

[0005] Therefore, there is an urgent need for a combined installation device of a microphone and an antenna and a handheld intelligent terminal with the device to overcome the above problems. Summary of the Utility Model

One end of the sound guiding channel is butt-connected and communicated with the sound hole of the microphone, and the other end of the sound guiding channel is butt-connected and communicated with the avoidance hole.

[0009] Optionally, a receiving groove is formed at the bottom of the sound guiding seat body, and the microphone is received in the receiving groove.

[0010] Optionally, the end of the sound guiding channel away from the avoidance hole is butt-connected and communicated with the receiving groove, and the end of the sound guiding channel away from the avoidance hole is directly opposite to the sound hole of the microphone.

[0011] Optionally, an annular chamfer is formed at the end of the sound guiding channel close to the avoidance hole.

[0012] Optionally, the end of the sound guiding channel close to the avoidance hole is horizontally arranged.

[0013] Optionally, the end of the sound guiding channel close to the receiving groove has an arc bending structure.

[0014] Optionally, a plurality of positioning convex columns are formed by the bottom of the sound guiding seat body protruding downward.

[0015] Optionally, both the sound guiding hole and the avoidance hole are arranged to penetrate along the horizontal direction.

[0016] Optionally, two limiting convex blocks are further formed on the housing, and the sound guiding seat body is fixedly limited between the two limiting convex blocks.

[0017] To achieve the above object, a second aspect of the embodiments of the present utility model provides a handheld intelligent terminal.

The circuit board is fixedly installed in the housing. The microphone is fixedly installed on the circuit board, and the microphone is electrically connected to the microphone connection end on the circuit board. The antenna is electrically connected to the antenna connection end on the circuit board.

[0018] Since the antenna of the microphone and antenna combined installation device of the present utility model is attached to the inner side wall of the housing, a sound guiding hole is formed on the housing, an avoidance hole is formed on the antenna, and the avoidance hole is directly opposite and communicated with the sound guiding hole; the microphone is fixedly installed in the housing, the sound guiding seat body is fixedly installed in the housing, a sound guiding channel is formed on the sound guiding seat body, one end of the sound guiding channel is butt-connected and communicated with the sound hole of the microphone, and the other end of the sound guiding channel is butt-connected and communicated with the avoidance hole.
