Abstract
The utility model discloses a loudspeaker box capable of connecting with a fixed-line telephone for hands-free calls. The loudspeaker box comprises a PCB, a loudspeaker, a microphone and a housing. The PCB, the loudspeaker, and the microphone are fixed in the housing. The loudspeaker and the microphone are respectively connected with the PCB by wires. The loudspeaker box also comprises a telephone handle wire interface. The telephone handle wire interface is connected on an end of a telephone handle wire, and the other end of the telephone handle wire is connected with a telephone. The loudspeaker box capable of connecting with the fixed-line telephone for hands-free calls is connected with the fixed-line telephone, and the connected fixed-line telephone does not need to improve. A hands-free call function can be realized by directly connecting the loudspeaker box capable of connecting with the fixed-line telephone for hands-free calls with an ordinary fixed-line telephone. The loudspeaker box has relatively louder sound, and a handsfree distance is larger than one meter. The loudspeaker box satisfies multi-user teleconferences, and has a record function and can record business negotiation contents and teleconference contents. The loudspeaker box is novel in creativity, simple and reasonable in structure, and practical in functions.
Description
Technical field
The utility model belongs to the communication equipment technical field, is specifically related to a kind of audio amplifier with microphone, can connect landline telephone and carry out hand-free call.
Background technology
At present, the most of telephone sets on the market, hand-free function a little less than, hand-free call send words sound less, the hand-free call close together is generally less than 0.5 meter, can't be used for many people videoconference, and office telephone machine in the market generally do not have sound-recording function.For addressing this problem, corresponding a kind of TeleConference Bridge appearred, and the hand-free call quality is better, but its system complex, expense is higher, and most of TeleConference Bridge, can only realize hand-free call, does not possess sound-recording function.
Summary of the invention
In order to overcome the above-mentioned technical problem that the prior art field exists, the purpose of this utility model is, a kind of audio amplifier that landline telephone carries out hand-free call that connects is provided, and realizes high-quality hand-free call, and has recording function of telephone.
The connect landline telephone that the utility model provides carries out the audio amplifier of hand-free call, and it comprises pcb board, loudspeaker, microphone and shell, and pcb board, loudspeaker, microphone are fixed in the enclosure, and loudspeaker are connected with pcb board by lead respectively with microphone.It also comprises the telephone handle line interface, and the telephone handle line interface connects an end of telephone handle line, and the other end of telephone handle line is connected with landline telephone.
The connect landline telephone that the utility model provides carries out the audio amplifier of hand-free call, its beneficial effect is, can connect landline telephone, the landline telephone that connects need not to improve, directly can connect the audio amplifier that landline telephone carries out hand-free call and be connected with normal telephone, and can realize the hand-free call function, sound is bigger, hands-free distance can satisfy many people videoconference greater than 1 meter; Have sound-recording function, can record commercial negotiation content and videoconference content; The intention novelty, simple and reasonable, the function practicality.
