Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic sounding unit in which a board on which electronic sounding components are mounted is attached to a thin case.

Conventionally, an electronic sounding device has been proposed that plays a melody when the cover of an album or the like is opened. It is difficult to assemble because the components are assembled and connected by lead wires, and each component is separate, and each component is thin and small, making it inconvenient to handle. They were pasted on, embedded in cardboard to protect or hide the design, or covered with paper so that the inside could not be seen. In this case, the set sound pressure and sound quality were not fully satisfied.

The purpose of this invention is to propose an electronic sounding unit in which each component is attached to a circuit board and mounted in a thin case so that it will not be damaged even if subjected to external forces such as bending, and the sound pressure and sound quality will be uniform. That's true.

A feature of the present invention is that a thin sounding body is fixed to a board on which a photosensitive switch element and an electronic sounding component for playing a melody or the like are mounted so that the thin sounding body and the board are substantially flat. , a substrate having the photosensitive switch element, an electronic sounding component, a thin battery, and the thin sounding body are attached to a thin case, and the thin case is made of a light-transmitting material or a portion facing the photosensitive switch element. It is made of a non-transparent material with a transparent part provided thereon.

The present invention will be explained below with reference to illustrated embodiments. 1st
As shown in FIGS. 3 to 3, the electronic sound generating unit has a thin case 1 made of a transparent material, and component units 2 are mounted inside the thin case.

The thin case 1 is formed into a rectangular shape, for example, and has a through hole 1a for sound emission on the front surface, and a recess 1b in which the component unit 2 is attached on the back surface.

The component unit 2 has one side of a sounding body 4 such as a thin speaker soldered to a board 3 so as to be substantially flat with the board, and a movable side 4a of the sounding body.
A lead wire 5 is connected between the board 3 and the board 3.
On the top, an electronic sounding component 6 consisting of a resistor or an IC, a photosensitive switch element 7 such as a CdS or a photo transistor constituting a switch, and a spring plate 8 are soldered, and a battery 9 is attached to the spring plate 8. There is.

When the electronic sound unit is constructed as described above and light is applied to the thin case 1 at the photosensitive switch element 7, the circuit switch is closed and the sound generating body 4 is turned on.
For example, a melody stored in the storage section of the electronic sound generating component 6 is played. The sound is resonated by the thin case, resulting in good sound quality and amplified volume. The thin case 1 may be provided with a cavity for adjusting sound quality and volume. Furthermore, since the component unit 2 is assembled on the board 3, it is convenient to handle, and since it is made up of thin parts, it is vulnerable to bending, etc., but its strength is increased by being attached to the thin case 1. It will not easily break due to external force.

If the thin case 1 is made of an opaque light-transmitting material, light can be applied to the photosensitive switch element 7 without making the internal component unit 2 visible, which is preferable in terms of design. The thin case 1 is made of a non-transparent material,
The light-transmitting portion facing the photosensitive switch element 7 may be formed of a light-transmitting material or a through hole. The through holes may be covered with a film or the like.

The back side of the thin case 1 may be closed with tape or a back cover, or may be attached to the product to be used using double-sided adhesive tape.

The sounding body 4 may be a piezoelectric buzzer, and the sound to be played may be a buzzer sound or other electronic onomatopoeia.
The battery may be connected externally.

The light-sensitive switch element 7 is used as a trigger switch, and the electronic sound unit is configured so that one song starts when exposed to light, and the electronic sound unit is incorporated into greeting cards, albums, jewelry boxes, suitcases, etc. When you want to play, you can open the cover or lid and place it in a bright place, and at other times you can close the cover or lid and place it in a dark place, or you can use it by attaching it.

Since the present invention is constructed as described above, the component units that are thin and vulnerable to external forces are protected and are easy to handle, which improves the sense of discomfort when the component units are hidden behind a thin case and attached to a product. The thin case improves the sound quality and volume, and when it is attached to the product, it can be attached to any place, and it is also easy to attach a design sticker that matches the product to the thin case. It is possible to provide an electronic sounding unit that can be attached and has excellent practical effects.
