Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] combine figure 1 , the ceramic mobile phone antenna that can receive FM signal in the present invention comprises antenna, lead, FM chip, and antenna is connected with FM chip by lead, and described ceramic mobile phone antenna adopts ceramic mixed material to make, and the composition of ceramic mixed material is silicon carbide 15%, 8% of boron carbide, 5% of uranium carbide, and 72% of silicon dioxide are formed by dry pressing with 1-5% polyvinyl butyral binder by mass ratio. The dry pressing molding process is to directly form ceramic powder through a press.

[0012] After receiving the RF signal, the antenna transmits the RF signal to the FM chip through the wire, and then adjusts it into an FM conduction signal through the FM chip, and restores it into sound through the speaker.

[0013] The invention is a ceramic mobile phone antenna capable ...

Abstract

The invention discloses a ceramic mobile phone aerial capable of receiving FM signals and comprises the aerial, a lead and an FM aerial. After receiving RF signals, the aerial transfers the RF signals to an FM chip via the lead to be adjusted into FM conductive signals by the FM chip to be restored into voice via a speaker. The invention adopts built-in aerial to free a subscriber from constraint of earplug aerial so as to realize direct FM reception; the ceramic mobile phone aerial is smaller in volume and more convenient in application compared with traditional earplug aerials and digital pens which are widely applied to mobile phones for FM reception, and has adequate flexibility in installation inside the mobile phones.

Description

technical field [0001] The invention belongs to a novel mobile phone FM radio antenna device, in particular to a ceramic mobile phone antenna capable of receiving FM signals. Background technique [0002] Frequency modulation (FM) radios have been used for many years in high-fidelity music and voice broadcasts, providing excellent sound quality, stable signals, and immunity to noise. Due to the maturity and stability of FM radio technology and the extensive use requirements provided to users, the application of FM radio on mobile phones has been widely welcomed by consumers and has become one of the necessary functions of mobile phones. However, the traditional FM design method must use a very long antenna. Most of the mobile phone products on the market currently use earphones (also FM antennas) as FM radio antennas. It is necessary to wear earphones to start FM radio. direct inconvenience. In addition, as consumers have higher requirements for product portability and con...
