Problems solved by technology

[0008] That is, in order to cope with the influence of the horn on the antenna radiation, the patent application arranges the main radiation strip of the antenna away from the horn of the mobile phone, but this makes the miniaturization design of the components difficult

Embodiment Construction

[0025] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0026] see figure 1 , figure 2 as well as image 3 , the embodiment of the horn and antenna assembly of the present invention includes:

[0027] A small sound cavity, the sound cavity includes an insulating support 11 as a cavity, a horn 12 located in the sound cavity, and an antenna first radiator 23 located on the insulating support 11;

[0028] The horn 12 includes an audio metal upper cover 24 as the second radiator of the antenna, and the feed point of the first radiator 23 is used to connect the external feed point and the feed point to form a PIFA antenna form, that is, an inverted F antenna. A first coupling gap 42 is provided between the first radiator 23 and the second radiator.

[0029] In the present invention, the audio f...

Abstract

The invention discloses a communication device, a horn and an antenna assembly thereof. The horn and the antenna assembly comprise a small tone cavity; the tone cavity comprises an insulation bracket serving as a cavity, a horn arranged in the tone cavity and a first antenna radiator positioned on the insulation bracket, wherein the horn comprises an upper voice frequency metal cover serving as asecond radiator of the antenna, the load point of the first radiator is used for connecting a disjunctive feeding point and an earth feeding point to form a PIFA antenna form, and a first coupling slot is arranged between the first radiator and the second radiator. The invention can enable the antenna to have the characteristics of super-small volume, high radiation, multiple frequency band and super-wide frequency band and turns the waste into the valuable.

Description

technical field [0001] The invention relates to an electronic device, in particular to a communication device and its horn and antenna assembly. Background technique [0002] At present, mobile phones are developing toward personalization, miniaturization, broadband, multi-antenna, high volume, and high sound quality. Especially with the arrival of the 3G era, the bandwidth requirements of the antenna are wider and the gain is higher. Due to the requirements for the sound quality of the mobile phone, the prior art mobile phone generally puts the speaker in the antenna bracket to form a sound cavity. The antenna is made on the antenna bracket. Because the horn is made of metal materials, the distance between the horn and the antenna is very close under the structural condition of miniaturized components, so it has a great impact on the radiation of the antenna, and it is often a negative impact, that is, it reduces the radiation of the antenna. [0003] In order to improve ...
