A mobile phone device with a microphone concealed structure

Abstract

The invention discloses a mobile phone device with a microphone concealed structure. A microphone channel with a combined closed space is arranged between the microphone component and the sound pickup hole; The length directions of the main circuit boards of the microphone components are consistent; the microphone sound channel is located below the keyboard of the mobile phone device and on both sides of the mobile phone device. Due to the use of the microphone channel of the combined closed space, and the design that the pickup hole of the microphone channel is concealed in the gap of the back cover part, the overall appearance of the mobile phone device is not affected by the pickup hole; plus The microphone channel in the closed space reduces the possibility of entering dust and other sundries or blocking the sound channel due to use; at the same time, the combined microphone channel also keeps the microphone components away from the antenna of the mobile phone device, greatly reducing the impact of the microphone components during work. The effect of the antenna improves the signal performance of the mobile device.

Description

technical field [0001] The invention relates to the microphone structure and application field of wireless communication terminal equipment, and more specifically, the improvement relates to a mobile phone device with a microphone concealed structure. Background technique [0002] With the progress and development of human electric hand technology, mobile phones have become one of the essential wireless communication terminal devices for people to communicate anytime and anywhere. Take China as an example. The China Mobile network was founded in 1987. Mobile phones have changed the way people communicate with each other. Ten years ago, China had only 10 million mobile subscribers, and many urban residents still mainly rely on China. Telecom's fixed-line telephone calls; after 2001, my country's economy developed rapidly, and the number of mobile phone users increased sharply. According to the data of the Ministry of Information Industry of China, China had 487.4 million mobil...

Problems solved by technology

No matter which mobile phone is used, the microphone part is mostly kept on the exposed surface of the mobile phone in the form of at least one small hole, which affects the overall look and feel of the mobile phone

[0004] like figure 1 As shown, the microphone in the prior art is located near A on the panel of the mobile phone, and the small hole is easily blocked by the cheek, causing the voice of the other party to listen to the phone to be reduced; when the microphone is located near B, it is easily affected by the airflow when speaking and produces a whistling sound , and it is also easy to cover the small hole with the fingers of the larger hand, resulting in the weak voice of the other party when listening to the phone

The mobile phones with these microphone positions are inconvenient to use

[0005] Secondly, if figure 1 As shown, when the microphone is located near C, for mobile phone manufacturers, in order to pursue ultra-thin or healthy design (here refers to the influence of electromagnetic waves too close to brain cells), the antenna is often installed at the bottom of the mobile phone. In or near the microphone, instead of being placed on the top of the phone as usual, so that the microphone may affect the performance of the antenna when it is working, reducing the signal performance of the phone
