In certain embodiments, the storage module 13 includes one or more erasable read-only memories (EROMs) in which the wireless transmission device is miniaturized and can repeatedly read and write data.

The processing module 15 can store the audio signal acquired by the audio capturing module 11 in the storage module 13 or read the audio signal stored in the storage module 13 when permitted.
In this or some embodiments, the processing module 15 writes a set of audio signals as one or more audio files to the storage module 13 and adds an end-of-file (EOF) flag to each audio file. . When reading one audio file of the storage module 13, the processing module 15 can determine the end of one audio file by reading the EOF, so that the processing module 15 can be connected to the wireless transmission device except the wireless transmission module 17. Modules (including themselves) can be prohibited.
In particular embodiments, without limitation, the processing module 15 may be an application-specific integrated circuit (ASIC), an advanced RISC machine (ARM), a central processing unit (CPU), a single chip controller, or other suitable operation. It can be a part and a command part.

The wireless transmission module 17 can transmit the audio signal stored in the storage module 13 by permitting the processing module 15 according to the transmission permission signal. In a specific embodiment, when the wireless transmission device operates in the hibernation mode, only the wireless transmission module 17 is permitted and the other modules are prohibited.
Here, when the wireless transmission module 17 receives the transmission permission signal, the processing module 15 is permitted by the wireless transmission module 17 to control other modules in the wireless transmission device. Further, the processing module 15 can read out the audio signal stored in the storage module 13 and control the wireless transmission module 17 to wirelessly transmit the audio signal to the transmission destination device of the transmission permission signal.
When the transmission destination signal transmission destination device transmits a transmission prohibition signal to the wireless transmission module 17, the processing module 15 prohibits other modules except the wireless transmission module 17, and then prohibits the wireless transmission module 17. .

  In one embodiment, the wireless transmission module 17 of FIG. 2 includes a reception unit 171, a transmission unit 173, and a switching unit 175. The transmission unit 173 and the switching unit 175 are electrically connected to the processing module 15, and the switching unit 175 is electrically connected to the reception unit 171 and the transmission unit 173.

Here, the receiving unit 171 acquires an interrupt request detection signal from the transmission destination device, and the switching unit 175 prohibits the processing module 15 and the transmission unit 173 according to the interrupt request detection signal.

In addition, both the reception unit 171 and the transmission unit 173 are idle for a predetermined period (for example, 15 seconds or 30 seconds) (that is, the signal is not transmitted between the wireless transmission device and any destination device). And the wireless transmission device specifies that it has completed the current signal transmission task and has not yet received a command from any destination device.
Here, the switching unit 175 prohibits the processing module 15 and the transmission unit 173. As a non-limiting example, the wireless transmission module 17 can be a Bluetooth® receiver, a wireless receiver in the IEEE 802.11 standard, or other suitable wireless receiver.

As a non-limiting example, the wireless transmission device can be applied to a wireless electronic stethoscope. The wireless electronic stethoscope is set to operate in hibernation mode after recording heartbeat or breath sounds in its memory. Here, another electrical device such as a mobile phone or a computer can wirelessly search for a wireless electronic stethoscope.
When receiving a radio wave from an electrical device searching for a usable wireless electronic stethoscope, the wireless electronic stethoscope returns the radio wave to establish a wireless connection between the wireless electronic stethoscope and the electrical device. The wireless electronic stethoscope's processing module will then allow it to read and transmit another heartbeat or breath sound file stored in the wireless electronic stethoscope after receiving a command identifying this action from the electrical device. Is done. The electrical device can also send a command to interrupt file transmission at any time.
On the other hand, when one or more files are completely transmitted, or when the connection between the electrical device and the wireless electronic stethoscope is turned off (ie, completely between the electrical device and the wireless electronic stethoscope). Without signal transmission, the wireless electronic stethoscope disables all modules and automatically operates in hibernation mode instead of operating mode until any electrical device requests or commands file transmission.
