Description

The present invention relates to a lateral pressure regulator attached to headphones.

In general, headphones consist of a pair of left and right housings each containing a sound source unit, and the outer sides of these housings are connected by a support member called a headband, which contains a leaf spring. It has a structure to hold it.
In headphones that are normally used, the left and right gaps between the ear pads of the headphones are made to fit most people, but for people with large heads, the left and right gaps between the ear pads of the headphones are too narrow, The side pressure was too strong, and I often had a headache when using it for a long time.
Some newly marketed headphones have a headphone lateral pressure adjustment function, but there is no simple lateral pressure adjuster that consumers can attach to their headphones.

Headbands for headphones and headphones in which a headband and a lateral pressure adjuster are integrated are known. This prevents users from attaching and detaching only the lateral pressure adjusters to and from their headphones (see Patent Document 1). ).

Japanese Patent Application Laid-Open No. 2021-040281

It can be attached to the headphones that consumers have on hand, and anyone can easily fine-tune the lateral pressure of the headphones, and the lateral pressure of the headphones can be easily adjusted in various usage situations such as web conferences, listening to music, and sports broadcasts. It has an adjustable function, and furthermore, even if the user falls asleep while using the headphones and drops the headphones from the head, the user will not be injured, the user's hair will not be caught and pulled out, and the entire corner will be To provide a side pressure regulator for a headphone which has an oval shape with no voids and has a simple structure which can be provided at a low cost.

The present invention has been made to solve the above-mentioned problems, and is composed of upper and lower elastic members, the lower member being called an adjuster main body and the upper member being called an adjuster lid.
The present invention will be described below in a landscape orientation.
The main body of the regulator is about 180 mm wide, about 50 mm deep, and about 40 mm high, and has an oval box shape with an open top. The wall is called the regulator main body wall, and a convex wall with a width of about 3 mm and a height of about 3 mm having four notches surrounds the upper edge of the regulator main body wall, and is called the outer peripheral convex wall, and the upper edge is called the outer peripheral convex wall. The four cutouts are referred to as peripheral cutouts.
The regulator cover is about 180 mm wide, about 50 mm deep, and about 10 mm high. The extending wall is called the regulator lid wall, and around the lower edge of the regulator lid wall is a concave portion with a width of about 3 mm and a height of about 3 mm, which fits with the outer peripheral convex wall of the regulator body. It is called the peripheral recessed wall.

On the back of the adjuster lid, prisms with a height of about 15 mm and a width and depth of about 5 mm protrude downward from four points on the inner side of the adjuster lid wall at positions about 32 mm in both left and right directions from the center in the longitudinal direction. , are called hook columns.
Each hook post has a protuberance extending in the longitudinal direction on the outer side of the tip region of the hook post, which is referred to as a hook post protrusion.
The adjuster main body has a square hole at a position where the hook post protrusion is fitted when the adjuster lid is closed, and is called a hook post protrusion receiving hole.
When the adjuster lid is closed, the hook column acts to prevent it from opening due to repulsive resilience, and when the adjuster lid is opened, it can be opened by the elasticity of the hook column.

A total of four holes with a diameter of about 8 mm are formed at positions of about 20 mm in both left and right directions from the left and right center and about 20 mm from the bottom on the front side and the back side of the adjuster main body wall.

The adjuster body wall has a round hole with a diameter of about 8 mm at a position about 35 mm to the right and about 2 mm downward from the position of the round hole for threading on the right side of the front. There is a round hole with a diameter of about 8 mm at a position about 5 mm to the right from a and about 1 mm to the right, which is called round hole piece b. There is a round hole of about 8 mm, called round hole piece c.
The round hole piece a, the round hole piece b, and the round hole piece c overlap each other, and the long hole formed by overlapping the round hole piece a, the round hole piece b, and the round hole piece c is called a long hole h.
The elongated hole h thus formed has a slightly upward shape when viewed from the front.
There is a symmetrical elongated hole at a position symmetrical from the center with respect to the elongated hole h, called elongated hole i. This is referred to as a slot k, but a total of four slots are collectively referred to as stringing slots.

Headphones consist of a headphone earpiece, a housing, and a headband.
Place the main body of the adjuster on top of the headband and spread the headband to the left and right with a string or binding band so that the headphone ear pads are in the correct position. , the lateral pressure applied to the ear of the person using the headphones can be adjusted.

If the headband is tied with a string or binding band at a position outside the inside of the slotted hole, the headband opens wide and the lateral pressure of the headphones on the ear is weakened.
If the headband is tied with a string or binding band at a position closer to the inside of the slotted hole, the headband opens slightly and the lateral pressure of the headphones on the ear increases.
Since the slotted hole for the string is a slotted hole in the shape of three overlapping circles, the string or binding band can be easily moved from the inside to the outside or from the outside to the inside, so the opening of the headband can be easily adjusted. You can easily adjust the lateral pressure applied to the ear of the headphone.

In the case where the regulator main body and the regulator lid are integrated, it is called an integrated regulator.
The integrated regulator has round holes with a diameter of about 16 millimeters passing through it at the same two locations as the lacing round holes, which are referred to as lacing through holes.
The integrated adjuster has two symmetrical elongated through-holes in the shape of three overlapped circles with a diameter of about 16 millimeters centered on the same position as the elongated hole for the string thread. It is called a string through hole.

Place the integrated adjuster on top of the headband, and spread the headband to the left and right with a string or binding band through the round hole and the oblong hole for the cord so that the headphone ear pads are in the correct position. By tying them together, the lateral pressure applied to the ears of the person using the headphones can be adjusted.

By tying the headband with a string or binding band at a position outside the inside of the slotted hole, the headband opens wide and the lateral pressure of the headphones on the ear is weakened.
If the headband is tied with a string or binding band at a position closer to the inside of the slot through which the string passes, the headband opens slightly and the lateral pressure of the headphones on the ear increases.
Since the slotted hole for passing through the string is an elongated hole in the shape of three overlapping circles, the string or binding band can be easily moved from the inside to the outside or from the outside to the inside, so the opening of the headband can be easily adjusted. , even with the integrated adjuster, the lateral pressure applied to the ear of the headphone can be easily adjusted.

The headphone lateral pressure regulator of the present invention can be attached to the consumer's handheld headphones.
Anyone can easily fine-tune the lateral pressure of the headphones by widening the headband of the headphones.
It has a function that allows you to easily adjust the lateral pressure of the headphones in three stages in various usage situations such as web conferences, listening to music, and sports broadcasts.
Since the overall shape is an oval with no corners, even if the user falls asleep while using the headphones and drops the headphones from the head, the user will not be injured. And my hair doesn't fall out.
It is possible to provide consumers with a side pressure regulator for headphones at a low cost.
