JPH04123598A - Sound leakage prevention device for headphone - Google Patents

Abstract

PURPOSE:To prevent sound leakage completely without relying on the judgement of the user by providing a noise detector comparing and detecting a sound volume of a headphone with an external noise sound and an electric signal transmitter informing it to the user of the headphone that the sound of the headphone is leaked outside to the device. CONSTITUTION:A headphone 3 is provided with a noise sound detector 1 detecting an external sound volume and an electric signal transmitter 2 sending a weak electric signal not giving any harm to the human body and a sound volume regulator 4 sets a sound volume of the headphone 3. Then the noise sound detector 1 is used to compare the sound volume of the headphone 3 set by the sound volume regulator 4 with an external noise sound and when the sound volume of the headphone 3 set by the sound volume regulator 4 is larger, the electric signal transmitter 2 sends an electric signal weak not giving harm to the human body to the headphone so as to inform it to the user of the headphone 3 and then the user reduces the sound volume by using the sound volume regulator 4. Thus, sound leakage externally is completely prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sound leakage prevention device for headphones used in audio equipment such as headphone stereos.

BACKGROUND ART Conventionally, as shown in FIG. 2, a user of headphones 3 recognizes external noise with his or her ears and adjusts the volume using a volume controller 4 according to the user's judgment to the extent that no sound leaks outside. is adjusted to prevent the sound from the headphones 3 from leaking to the outside.

Problems to be Solved by the Invention However, in the conventional configuration described above, the volume is adjusted at the discretion of the headphone user, so even if the user intends to listen at a low volume, there may be sound leakage. There was a problem in that it was not possible to completely prevent sound leakage.

The present invention solves the above-mentioned conventional problems, and aims to provide a sound leakage prevention device for headphones that can completely prevent sound leakage without relying on the user's judgment.

Means for Solving the Problem To achieve this object, the sound leakage prevention device for headphones of the present invention includes a noise detection device that compares and detects the volume of the headphones with external noise, and a noise detection device that detects the volume of the headphones by comparing it with external noise. The device is equipped with an electrical signal sending device that notifies the headphone user that the headphone is in use.

With this configuration, by comparing the volume of the headphones with external noise, if the volume of the headphones is higher, the sound leakage from the headphones is eliminated.

Dohon users will be notified.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, headphones 3 that can be used to listen to sounds from audio equipment include a noise detection device 1 that detects external sound volume, and an electrical signal transmitter that transmits weak electrical signals that are harmless to the human body. A device 2 is provided, and a volume controller 4 is used to set the sound flowing through headphones 3.

The sound leakage prevention device of the headphones configured as described above is configured using the noise detection device 1, the operation of which will be explained below.
and external noise), and if the volume of the head (3) set with the volume controller 4 is higher, the electric signal transmission and device 2 should send a weak electric signal that is not harmful to the human body.・Inform the users of headphones 3 by playing it on the headphone.
According to the present embodiment, the user lowers the volume using the volume controller 4.2 According to this embodiment, the noise detection device 2-12 compares and detects the volume of the headphones (the volume and the external noise). By providing an electrical signal selection device that informs the user that it is louder than the noise, the noise detection device can mechanically compare the volume of the headphones with the external noise, and if the volume of the headphones is louder than the external noise. gives the user a mild impact that is harmless to the human body, so the user is sure to notice and reduce the volume of the headphones to reliably prevent sound leakage.

Effects of the Invention As is clear from the description of the embodiments above, the present invention has a configuration in which headphones are provided with a noise detection device and an electrical signal selection device, so that the user can detect whether the sound of the headphones is leaking to the outside. It is possible to realize an excellent headphone sound leakage prevention device that can reliably reduce the volume of the headphones and completely prevent sound leakage to the outside.
