BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a transceiver microphone, and more particularly, to a compact and portable clip-on transceiver microphone. 
     2. Description of the Related Art 
     Owing to technological progress, electronic products all head for the trend of using wireless transmission in place of conventional wireline transmission. Since electronic products capable of conveniently searching information or sending e-mail through wireless networks penetrate into all aspects of daily life of modernized people, mobile devices, such as smart phones, tablet personal computers (PCs), and notebook computers have become more and more indispensable and greatly lessen the use of desktop PCs with wired connection to networks for communication. Likewise, a conventional wired speaker microphone also needs to be connected to a receiver, such as a speaker, through a cable to transmit the speaker&#39;s voice to the receiver for playing. Because of the physical cable, the user can only speak in a range limited by the cable and movement freedom is restricted to prevent the microphone connector from being disconnected. 
     One conventional way of wirelessly transmitting voice signals can be implemented by a wireless microphone and a receiving host. When speaking to the wireless microphone, user&#39;s voice can be wirelessly transmitted to the receiving host and played by a speaker connected to the receiving host. 
     Another conventional way of wirelessly transmitting voice signals can be implemented by an audio receiver and a wireless transceiver. The wireless transceiver has an audio receiver and a wireless transceiver. The wireless transceiver has a microphone jack connected to the audio receiver through a connection wire for the audio receiver to generate sound signals which are transmitted out by the wireless transceiver. Being sort of bulky, the wireless transceiver is oftentimes hung at a lower back of the user. Therefore, the connection wire that must be extended from the sound-uttering position to the audio receiver is rather long and causes operational inconvenience for being far from the sound-uttering position of the user. 
     SUMMARY OF THE INVENTION 
     An objective of the present invention is to provide a clip-on transceiver microphone with compact size and portability. 
     To achieve the foregoing objective, the clip-on transceiver microphone has a first body, a second body, and a pivot shaft assembly. 
     The first body has a circuit board, a microphone jack, a first shaft bracket, and a first force exertion portion. 
     The microphone jack is formed on the first body and is electrically connected to the circuit board. 
     The first shaft bracket is formed on an inner surface of the first body. 
     The first force exertion portion is located on a top portion of an outer surface of the first body opposite to a portion of the inner surface of the first body with the first shaft bracket. 
     The second body has a battery, a second shaft bracket, and a second force exertion portion. 
     The battery is mounted inside the second body with a power wire electrically connected to the circuit board in the first body to supply power to the circuit board. 
     The second shaft bracket is formed on an inner surface of the second body. 
     The second force exertion portion is located on a top portion of an outer surface of the second body opposite to a portion of the inner surface of the second body with the second shaft bracket. 
     The pivot shaft assembly is pivotally mounted through the first shaft bracket and the second shaft bracket with a bottom portion of the inner surface of the first body abutting against a bottom portion of the inner surface of the second body after the pivot shaft assembly is assembled with the first body and the second body. 
     Given the foregoing clip-on transceiver microphone, the circuit board is mounted inside the first body, and the battery is received inside the second body with the circuit board electrically connected to the battery. Therefore, the size of the transceiver microphone is significantly reduced. The first body and the second body are pivotally connected with the pivot shaft assembly mounted between the first body and the second body to form a clipping structure. Accordingly, after force is applied on the first and second force exertion portions, the clip-on transceiver microphone can be clipped on an object of a user and carried around with the user. 
     Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
