Detailed Description

The utility model is described in more detail below with reference to the drawings and examples.

The utility model discloses a voice call enhancement earphone, please refer to fig. 1 and 4, which comprises:

The Bluetooth SOC module 1 is used for establishing Bluetooth connection with the intelligent terminal;

the bone voiceprint sensor 5 is connected to the Bluetooth SOC module 1, and the bone voiceprint sensor 5 is used for collecting bone vibration waves of human ears and transmitting the bone vibration waves to the Bluetooth SOC module 1 in an electric signal mode.

In the above structure, the bluetooth SOC module 1, the audio amplifier 2, the speaker 3 and the conversation microphone 4 form a basic structure of a bluetooth headset, audio signals received by the bluetooth SOC module 1 are amplified and restored by the audio amplifier 2 and the speaker 3, conversation voice is collected by the conversation microphone 4 and then transmitted to the intelligent terminal by the bluetooth SOC module 1, on the basis, the bone voiceprint sensor 5 is additionally arranged, the bone voiceprint sensor 5 is attached to an ear of a person, bone vibration waves of the ear of the person can be collected, when a user speaks, the bone vibration waves are sensed by the bone voiceprint sensor 5 and then converted into electric signals to be transmitted to the bluetooth SOC module 1, and the signals collected by the conversation microphone 4 and the bone voiceprint sensor 5 are overlapped and then are uploaded to the intelligent terminal by the bluetooth SOC module 1, so that a high-definition voice signal of the person is obtained, and a high-quality conversation function is realized.

Referring to fig. 1, the main structure of the earphone of the present utility model includes an earphone main body 6 and an ear hook 7, the bluetooth SOC module 1, the audio amplifier 2, the speaker 3 and the microphone 4 are all disposed in the earphone main body 6, and the bone voiceprint sensor 5 is disposed on the ear hook 7.

Regarding the specific working principle of the earphone of the present utility model, please refer to fig. 2 and 3, the earphone mainly relies on a conversation microphone arranged in the earphone shell to collect/pick up voice signals and feed back the voice signals to the main control of the bluetooth SOC module 1 during communication, meanwhile, a bone voiceprint sensor arranged on the ear hook collects bone vibration signals of the ear part of a person when speaking, converts the bone vibration signals into electric signals and feeds back the electric signals to the main control, the main control carries out superposition processing on the two received signals and then sends the signals to a receiving end through a mobile phone network, in this process, because the bone voiceprint sensor is not interfered by external environment, the collected signals are pure voice signals, and the phase and the frequency width of the collected signals are basically consistent with those of voice signals collected by the conversation microphone, therefore, when two groups of voice signals with the same phase and frequency width are superposed, the loudness (amplitude) of the voice signals can be improved, and when the whole signals are played back, the loudness of the voice signals can be improved, thereby improving the conversation quality (i.e. the receiving end is more clear).

Specifically, when a call is made, the call microphone generates two electric signals, one is a human voice signal V _voice1 and one is an environmental noise V _noise1, and meanwhile, the bone voiceprint sensor also generates an electric signal, namely a human voice signal V _voice2, because the bone voiceprint sensor is not affected by the environmental noise, the generated V _voice2 signal is basically consistent with the V _voice1 in phase and bandwidth, and the V _voice1 and the V _voice2 can be overlapped in the system to obtain a V _voice3 with higher human voice loudness, so that the bone voiceprint sensor has the following functions:

V_{Communication system Mic}+V_{Bone voiceprint}＝(V_voice1+V_nosie1)+V_voice2≈V_voice3+V_nosie1;

Based on the operation, the voice signal with high definition can be obtained, so that high-quality conversation is realized.

Referring to fig. 1, regarding the preferred position of the bone voiceprint sensor 5:

The bone voiceprint sensor 5 is arranged at one end of the ear hook 7 close to the earphone main body 6;

or the bone voiceprint sensor 5 is arranged at a position of the earhook 7 close to the uppermost end;

Or the bone voiceprint sensor 5 is arranged at a position of the earhook 7 near the lowest end.
