Alternatively, the second transmitter is electrically connected to the memory 21 so that the audio document outputted from the presenter body 10 to the second transmitter through the first transmitter can be directly transmitted to the memory 21 through the second transmitter.

Or both the second transmitter and the interface 25 are electrically connected to the memory 21.

The above-mentioned electric connection mode can be wire connection or wireless connection.

It can be understood that, since the demonstrator body 10 of the above-mentioned embodiment has the sound pickup 11 and the adapter 20 has the memory 21, the demonstrator body 10 can realize the recording function and save the recorded file in the adapter 20, the storage and carrying are more convenient, and in addition, the adapter 20 with the memory 21 can help the whole demonstrator to realize more functions, including but not limited to voiceprint encryption and the like, and the memory 21 is integrated in the adapter 20, without affecting the weight and volume of the demonstrator body 10, so that the whole demonstrator body 10 is more light and convenient to use.

The utility model provides a voice print that recording, storage and recording combine the storage can be realized to the demonstrator, and the whole demonstrator body 10's simple structure, and the quality is light.

In some embodiments, as shown in fig. 2, the presenter body 10 includes: this body shell 12, adapter 11 and first transmitter are all installed in this body shell 12, and body shell 12 can also be equipped with the hole that is used for dodging adapter 11, and adapter 11 and first transmitter are all installed in this body shell 12, and this body shell 12 can play the effect of protection to adapter 11 and first transmitter.

The body case 12 is provided with a receiving chamber 13, and the adapter 20 is adapted to be received in the receiving chamber 13. Thus, during periods of non-operation, the presenter body 10 and adapter 20 may be stored as a single unit for portability.

As shown in fig. 3 to 4, the adapter 20 includes: the adapter shell 22, the storage 21, the second transmitter and the socket 25 are all mounted on the adapter shell 22, wherein the storage 21 and the second transmitter can be mounted in the adapter shell 22, one part of the socket 25 can be mounted in the adapter shell 22, the other part of the socket 25 extends out of the adapter shell 22, the adapter shell 22 can protect the storage 21 and the second transmitter, and at least part of the adapter shell 22 is suitable for matching with the inner side wall of the accommodating cavity 13.

As shown in fig. 2, the accommodating chamber 13 is disposed at an end of the body case 12, the accommodating chamber 13 is open at the end of the body case 12, a notch 14 penetrating through the accommodating chamber 13 is disposed on a side wall of the body case 12, and the notch 14 may extend to the end of the body case 12.

As shown in fig. 3 and 4, the adapter case 22 includes a body case 23 and a boss 24, and the body case 23 is adapted to be inserted into the accommodation chamber 13 from an end of the body case 12 such that the boss 24 is located at the notch 14.

Thus, when the adapter 20 is separated from the presenter body 10, the adapter 20 can be removed by pressing the projection 24 and pushing the adapter 20 in the end direction at the notch 14.

The body case 23 and the boss 24 may be formed in one body.

As shown in fig. 3 and 4, in an actual implementation, the protrusion 24 is provided on a side wall of the body case 23, and the width of the protrusion 24 is smaller than that of the side wall of the body case 23. In this way, the boss 24 is easily formed and the notch 14 fitted out of the boss 24 is easily machined.

As shown in fig. 3 and 4, the socket 25 protrudes from one end of the main body case 12, and the protrusion 24 is disposed on one end of the sidewall of the main body case 23 away from the socket 25. Thus, when the adapter 20 is stored in the demo body 10, the socket 25 can be protected by the body case 12, and the length of the whole demo is short.

As shown in fig. 2 and 3, the notch 14 and the corner of the boss 24 are respectively provided with a circular arc transition section. This prevents the corners from scratching the operator.
