Embodiment Construction

[0025] see figure 1 , which is a schematic structural diagram of an automatic volume adjustment device in an embodiment of the present invention. It should be noted that the volume adjustment device involved in the present invention may be an electronic device that can produce sound, such as earphones. In this embodiment, a wired earphone is used as an example for illustration. The earphone may be a wired earphone that transmits audio signals through an earphone cable, or a wireless Headphones of this type, such as Bluetooth headsets that transmit audio signals using high-frequency signals in specific frequency bands.

[0026] In this embodiment, the earphone 1 includes an earphone cable 10 and an earpiece 20 . In this embodiment, one end of the earphone cable 10 is electrically connected to the earpiece 20, and the other end is used to electrically connect to the audio signal generating device. Therefore, the earphone cable 10 is used to output the audio signal output by th...

Abstract

The invention relates to automatic volume regulating equipment and a volume regulating method thereof. The automatic volume regulating equipment comprises an electroacoustic converter and an outer shell for containing the electroacoustic converter, and the electroacoustic converter is used for converting a received electric signal which includes an audio signal into an acoustic signal. The automatic volume regulating equipment is characterized in that the electroacoustic converter comprises a magnet, a coil and a vibrating membrane; the magnet is used for generating a magnetic field; the coil is positioned in the magnetic field and is further used for receiving the electric signal; the vibrating membrane generates the acoustic signal corresponding to the electric signal; the vibrating membrane is attached onto the coil; the resistance value of the coil is increased along with the rise of a temperature; and the output power of the coil, which corresponds to the audio signal, is decreased, so that the vibrating membrane automatically decreases the volume of the acoustic signal correspondingly.

Description

technical field [0001] The invention relates to an automatic volume adjustment device in the field of electroacoustic conversion, in particular to an earphone for automatic volume adjustment. Background technique [0002] With the widespread promotion of entertainment electronic devices such as Walkman, CD, MP3, MP4 and computers, earphones have become a basic accessory of entertainment electronic devices as audio output components. When wearing earphones to listen to music or other voice materials, the sound frequency is concentrated on the vibrating membrane of the earphones. At the same time, because the earphones are basically in the auricle or very close to the ears, the propagation range of the sound waves is very small and relatively concentrated. Or wearing earphones at a higher volume to listen to voice data will cause the eardrum of the human ear to be subjected to long-term or sudden impacts, and the auditory nerves of the human body will be stimulated and excited...
