The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

In the prior art, a teacher usually uses a public address device to amplify sound in the course of giving lessons, and although the voice of the teacher can be prevented from speaking with high voice, the voice-using time of the teacher is not shortened. Consider that the teacher always inevitably reads the text during the course of giving lessons. The utility model discloses aim at utilizing OCR (optical character recognition) technique, provide a teaching public address equipment that possesses characters and change speech function and be used for this teaching public address equipment's headset and megaphone.

In order to more clearly illustrate the technical solution proposed by the present invention, the following examples are given.

Example 1

Referring to fig. 1 to 5, the present embodiment provides a teaching microphone device with a text-to-speech function, which includes a headset 1 and a microphone 2. It is noted that the headset 1 and the loudspeaker 2 referred to herein comprise the functionality of the existing headset 1 and loudspeaker 2. That is, the headset 1 can be used to pick up sound to acquire target voice information, and the loudspeaker 2 can also be used to amplify the sound.

The difference with the prior art lies in: the headset 1 is provided with an identification component 11 for identifying text information, a first processor component 12 for converting the text information into a first audio signal and a wireless transmitting component 13 for outputting the first audio signal; the wireless transmitting part 13 and the identification component 11 are both electrically connected with the first processor part 12.

In a specific application, the headset 1 can be made into the shape of the existing headset 1, and can also be made into the shape of an ear-hanging type bluetooth headset. The present embodiment is not limited to this, but no matter what shape is set, in order to realize the function of acquiring text information and converting the text information into audio information, the identification component 11 needs to be arranged on the headset 1.

The loudspeaker 2 is provided with a wireless receiving component 21 for receiving the first audio signal and a loudspeaker component 22 for playing the first audio signal; the sound amplifying part 22 is electrically connected with the wireless transmitting part 13. In one embodiment, the speaker 22 is a horn.

In specific use, please refer to fig. 6, taking the reading text scene as an example: when the teacher needs to read the text of the book, the identification component 11 on the headset 1 can be aligned with the text to be read. The recognition component 11 can recognize the characters on the book to obtain the corresponding character information, the first processor component 12 outputs the character information as a first audio signal, and the first audio signal is sent to the loudspeaker 2 through the wireless transmission component 13 on the headset 1. The wireless transmission part 13 on the loudspeaker 2 receives the first audio signal, which is played by the loudspeaker part 22. Therefore, when needed, the text information on the book can be identified and converted into sound to be played. Is beneficial to reducing the using time of teachers.

Referring to fig. 1, fig. 3 and fig. 4, as a preferred implementation manner, the identification component 11 includes a camera 111 and an identification module, the camera 111 is electrically connected to the identification module, and the identification module is electrically connected to the first processor component 12. In particular, the recognition module is implemented by OCR technology, which can be implemented by a person skilled in the art. When the device is used, the to-be-read text content is aligned through the camera 111, and text information in an area aligned by the camera 111 is identified through the identification module.

Referring to fig. 1, as a preferred implementation, the headset 1 further includes a microphone 14 for picking up the voice of the wearer. As for the sound pickup function, the present embodiment may be the same as that in the related art. However, compared with the prior art, the utility model discloses turn into first audio signal's function and sound after the characters discernment and pick up the function and combine together for headset 1 not only can pick up sound, can also turn into first audio signal with the characters. And then the loudspeaker in wireless connection can ensure normal use of the sound amplifying function on one hand and convert characters into voice on the other hand.
