Detailed Description
Referring to fig. 1 and 2, which show a specific structure of a preferred embodiment of the present invention, the present invention is a talking earphone with wind noise resistance based on bone conduction technology, including a main body 10, the main body 10 having an inner portion 11 to be placed in an ear canal and an outer portion 12 to be located outside the ear canal, the inner portion 11 having a bone conduction microphone 20 at a position corresponding to the ear canal, the outer portion 12 having a bone conduction speaker 30.
The utility model discloses a traditional earphone form is broken to the earphone, and the loudspeaker of traditional earphone form is put into the duct, and the microphone is put near mouth radio reception outside the duct. When the headset is in a noisy or windy place, the spoken sound is often covered by the noisy sound and is not heard by the other party. The utility model discloses a principle is to plug bone conduction microphone 20 into the duct to make an uproar and make a noise restriction with all outside wind, utilize human inside duct to collect sound, improve speech quality again through optimizing. Since the ear canal is acted upon by the bone conduction microphone 20, the speaker is placed outside the ear, and the bone conduction technique is used to achieve the conversation effect.
Conventional bone conduction microphones are typically applied outside the ear canal, for example, and are often used to vibrate and produce sound using the larynx. The bone conduction microphone 20 is applied to the ear in the scheme, and the sound production of vibration in the ear canal is directly collected. Preferably, the bone conduction microphone directly contacts with the skin of the auditory canal, and is a piezoelectric ceramic bone conduction microphone which generates voltage change by utilizing the inverse piezoelectric effect of piezoelectric ceramic to collect sound. In addition, bone conduction telephone reception based on other technologies can be realized. Simultaneously in order to increase the comfort of wearing, the bone conduction microphone can also be the skin that contacts the duct between the contact, sets up the silica gel or the sponge that increase the comfort on the binding face between bone conduction microphone and skin and so on.
And, the headset further comprises a circuit board 40. The circuit board 40 is provided with a sound optimization processing unit 41, a bluetooth main chip 42 and an audio power amplifier 43. The sound optimization processing unit 41 has at least an amplifier 411 and an audio processor 412, wherein the amplifier 411 is electrically connected to the bone conduction microphone 20 and the audio processor 412. The bluetooth main chip 42 is electrically connected to the audio processor 412, and an antenna 421 is disposed on the bluetooth main chip 42. The audio power amplifier 43 is electrically connected to the bluetooth main chip 42 and the bone conduction speaker. Further, a key 44 is provided, and the key 44 is electrically connected to the bluetooth main chip 42. And, there is a power supply 45, the power supply 45 is electrically connected to the bluetooth main chip 42.
Since the bone conduction microphone 20 directly obtains the sound of the ear canal with poor quality, the sound quality can be improved and the sound can be made bright by the sound optimization processing unit 41. The amplifier 411 amplifies the volume signal received by the bone conduction microphone 20, and then processes the sound signal by the audio processor 412, for example, it may need to perform parametric equalization, frequency division, delay, and sound mixing on the sound signal for signal processing. In some embodiments, the audio processor 412 is implemented in hardware, and in other embodiments, is implemented in software, such as a DSP power amplifier.
In this embodiment, the earphone for resisting wind noise for conversation based on bone conduction technology is a wireless true bluetooth earphone, that is, a TWS earphone popular at present, and the bluetooth master chip 42 is arranged to implement the synchronization of sound playing of the left and right earphones and the interconnection with an intelligent terminal (for example, a mobile phone) for receiving signals of an intelligent terminal, and the wireless mode facilitates wireless conversation of people.
The audio power amplifier 43 is a common component in the field of acoustics, and its working principle is to amplify and process the sound signal received by bluetooth, and then transmit the sound signal to the bone conduction speaker for playing. The circuit composition and control method are not described herein.
As shown in fig. 2, it is one of the implementation manners of the present invention, the earphone for speaking and resisting wind noise based on the bone conduction technology has a sponge plug 13 for the built-in part 11, a communication channel 14 is arranged in the middle of the sponge plug 13, and the bone conduction microphone 20 is arranged in the communication channel 14, so that the bone conduction microphone 20 can acquire the sound transmitted by the ear. As a preferable option, the bone conduction microphone 20 is mounted on a vibration-proof member 15, the vibration-proof member 15 is assembled to the body 10, and the vibration-proof member 15 is, for example, silicon rubber, and has a vibration-absorbing function so that noise generated by other vibrations is buried in addition to sound collection, which can keep vibration from being transmitted to the bone conduction speaker to generate an unnecessary vibration to be attached to the earphone body 10.
In other forms, the anti-wind noise earphone for conversation based on the bone conduction technology can also be a headset, or an earphone hung on the neck by a rope, and can also be other forms of earphones.
The working principle of the utility model is as follows: the call process includes two states of transmitting voice to the opposite side and receiving voice of the opposite side.
When the sound is transmitted to the opposite side, the earphone wearer speaks, and the speaking has two transmission modes, namely, the transmission through air and the transmission through the inside of a human body, wherein the auditory canal can also transmit the sound, and belongs to the transmission mode in the inside of the human body. Since the bone conduction microphone 20 is placed in the ear canal after being worn, the vibration during the call is transmitted from the ear canal to the bone conduction microphone, which serves as a receiver, receiving the speaking signal and the internal environment of the ear canal is free from wind noise and other noise, so that the sound recorded into the microphone is pure and free from impurities. However, since bone conduction telephone reception is different from traditional air-borne telephone reception, and the directly recorded voice is dark, the voice optimization processing unit 41 is provided to improve the voice quality, and then the bluetooth main chip 42 sends the telephone reception communication content to the other party of the call through the intelligent terminal (such as a smart phone).
When receiving the voice of the other party, the bluetooth main chip 42 receives the voice call content from the intelligent terminal, and after passing through the audio power amplifier, the bone sensing loudspeaker generates vibration. The vibration acts on the human ear bone and human position, and is transmitted through the ear nerve to achieve the purpose of receiving and receiving sound.
The utility model discloses an earphone can also be applied to occasions such as recording, listening music, is not limited to the conversation and uses.
To sum up, the design of the present invention is characterized in that, since the bone conduction microphone 20 is disposed in the built-in part 11 of the earphone main body 10, the built-in part 11 is to be placed in the ear canal, and directly obtains the sound from the ear canal, rather than the traditional way of obtaining the sound again through air conduction; and, the bone conduction speaker 30 is provided to the external portion 12 of the earphone body 10, the external portion 12 being located outside the ear canal, rather than the conventional way of placing the speaker inside the ear canal. The bone conduction microphone 20 is plugged into the ear canal to limit all external wind noise and noisy sound, the ear canal inside the human body is used for collecting sound, the bone conduction microphone 20 directly obtains poor sound quality of the ear canal, and the sound quality can be improved through the arranged sound optimization processing unit 41, so that the sound is bright. Since the ear canal is acted upon by the bone conduction microphone 20, the speaker is placed outside the ear, and the bone conduction technique is used to achieve the conversation effect.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
