Description

Headphones that play ambient sound

technical field

The present invention relates to earphones, in particular to an earphone that allows users to choose whether to listen to ambient sounds at the same time, and specifically to an earphone that can play ambient sounds.

Background technique

Due to the maturity of music compression technology and the electronic industry, MP3 players have been mass-produced. At present, the general public has almost one MP3 player. It has become the most popular electronic product nowadays. The business opportunities of MP3 players are huge, so that all manufacturers have invested in research and development. Now no matter on the road, on the subway or on the bus, people can be seen wearing earphones and indulging in the beautiful world of music. In addition, some manufacturers have conducted research on earphones and developed a variety of earphone styles, such as: full-cover earphones, half-cover earphones, and earbud earphones. Most of their design concepts still tend to fully present music Its own characteristics, for example: the above-mentioned earplug type earphone completely seals the inner cavity of the ear to block the sound of the outside world, so that the music itself can be completely presented in front of the user without being disturbed.

However, there are hidden risk factors in this design concept. When an emergency occurs, the user may not hear other people's warning sounds, horn sounds or reminder sounds, which may cause danger or delay time.

Contents of the invention

In view of the above-mentioned earphones often in actual use, the user ignores other environmental sounds such as warning sounds, horn sounds, or broadcasting sounds, causing the user to react too late and fall into danger. Therefore, the present invention aims at the above-mentioned problems. Based on years of professional knowledge and accumulated technical experience, people have developed and designed an earphone capable of playing ambient sounds of the present invention, which effectively solves the above-mentioned problems.

In order to realize the above-mentioned purpose of the present invention, the present invention provides a kind of earphone that can play ambient sound, comprising: at least one pronunciation part, is located on the earphone, in order to output sound source signal; A signal connection part, is located on the earphone, respectively Connect with each described sounding part, for connecting an external portable electronic device, and transmit the first sound source signal played by the described portable electronic device to each described sounding part; an environmental sound module, set The earphone includes a sound source acquisition part and an adjustment part, and the sound source acquisition part is connected with the adjustment part to obtain an ambient sound through the earphone. The adjustment unit is used to drive the sound source acquisition unit and adjust the size of the environmental sound; a control unit is connected to the environmental sound module and the pronunciation unit respectively, and the environmental sound convert it into a second sound source signal, and transmit the second sound source signal to the sounding part.

The earphone includes an ambient sound effect module and a sounding part, which can be connected to a portable electronic device, and output audio signals such as voice, music or radio played by the portable electronic device through the sounding part. This ambient sound module can obtain the external surrounding ambient sound. And the earphone outputs the obtained ambient sound through the pronunciation part. In this way, when the user listens to audio signals such as telephone, music, or radio through the sounding part, the user can still obtain the ambient sound in the environmental sound effect module, and can also listen to the ambient sound through the sounding part.

Detailed ways

Below by embodiment of the present invention and accompanying drawing, to the purpose of the present invention, shape, structure device feature and effect thereof, be described in detail as follows:

An earphone capable of playing ambient sound according to the present invention is shown in FIGS. 1 and 2 . The earphone 20 (such as: bluetooth wireless earphone or earphone) includes a control part 40 (such as: audio decoder, audiodecorder), a signal connection part 70 (connector, such as: earphone connector or bluetooth receiving module), an environmental sound module 30 (background audio module) and at least one pronunciation part 50 (speaker). Wherein, each sounding part 50 is provided on the earphone 20 . The signal connection part 70 is provided on the earphone 20 and is connected with each sound emitting part 50 . In addition, the signal connection part 70 can communicate with the portable electronic device 80 (such as: MP3 player or mobile phone) in a wired or wireless manner, and receive the first sound source signal played by the portable electronic device 80 (such as: voice, music or radio, etc.). Then, the signal connecting part 70 transmits the first sound source signal to each sounding part 50 for broadcasting.

The environmental sound effect module 30 includes a sound source acquisition unit 34 and an adjustment unit 31 (volume tuner). The sound source capturing part 34 is disposed on the earphone 20 , and the sound source capturing part 34 can be a microphone with wide-area sound collecting capability. The sound source extraction part 34 is connected with the adjustment part 31, and after the adjustment part 31 of the environmental sound effect module 30 is turned on, the adjustment part 31 promptly drives the sound source extraction part 34, so that the ambient sound around the earphone 20 is obtained from the outside, wherein , the user can also adjust the volume of the ambient sound.

The control unit 40 is connected to the environmental sound effect module 30 and each sound producing unit 50 respectively. After the sound source extraction unit 34 acquires the ambient sound, it first converts the ambient sound into a voltage signal and sends it to the control unit 40 . The control unit 40 converts the voltage signal into a digital signal, and transmits the second sound source signal to each sound generating unit 50 after the second decoding conversion. Therefore, the earphone 20 can simultaneously output the acquired ambient sound and the sound source signal through each sounding part 50 . In this way, when listening to the phone, music or radio, the user can still listen to the ambient sound through the sound emitting parts 50 after the ambient sound module 30 obtains the ambient sound. For example: arrival announcement, horn sound, warning sound, etc., to avoid unresponsive or missing important information.

In an embodiment of the present invention, as shown in FIGS. 1 and 2 , the environmental sound effect module 30 further includes a sound amplifier 35 (amplifier). The sound amplifying part 35 is connected with the adjustment part 31, and after the adjustment part 31 is turned on, according to the degree of adjustment of the adjustment part 31, the volume of the ambient sound is proportionally raised or lowered. The adjustment part 31 can be designed as, for example, a disc-shaped turntable 32 , and the turntable 32 can rotate on the earphone 20 . When the turntable 32 is rotated, the environmental sound effect module 30 can trigger the sound source capture part 34 , so that the sound source capture part 34 captures the surrounding sound of the earphone 20 . The turntable 32 can be rotated from one side of the earphone 20 to the other side. The loudspeaker 35 increases the volume of the ambient sound proportionally according to the degree of rotation of the turntable 32 . On the contrary, when the turntable 32 is turned back to one end on the earphone 20 , the ambient sound effect module 30 stops the sound source capturing part 34 from capturing ambient sound around the earphone 20 .

In addition, in the present invention, referring back to FIGS. 1 and 2 , the earphone 20 also includes a sound collecting part 60 . The sound collecting part 60 may be a microphone with high directivity sound collecting ability. The sound receiving part 60 is connected with the signal connecting part 70 , and after receiving the ambient sound, converts the ambient sound into a voltage signal, and then sends it to the portable electronic device 80 through the signal connecting part 70 .

The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications that can be easily conceived in the field of the present invention described by those skilled in the art can be covered. In the protection scope of the present invention.
