Description

Side-out buzzer structure

This creation is a side-out buzzer structure, especially for a traffic vehicle, industrial safety, commercial warning, or home security warning for the side-sound buzzer structure.

The buzzer is an electronic sounder that is powered by voltage and is widely used in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronics, telephones, timers, etc. as sounding devices. The buzzer and the horn are different products. When the buzzer is powered on, it will emit a vibration warning tone for anti-theft or other warning purposes.

The conventional buzzer structure has a sounding direction that is consistent with the direction in which the piezoelectric ceramic piece vibrates. In order to form a sufficient chamber space to achieve an appropriate sound pressure, the buzzer structure must have a certain thickness. . In addition, there are many portable electronic devices, such as tablets, cameras, etc. Because of their small size and short size, the sound outlet is often not designed directly in front of or behind the product, so how to design the sound from the side (side) side The buzzer has become an important issue.

This creation is a side-out buzzer structure, which solves the problem of how to make sounds from the side, which is light and thin, and can be used with different product applications.

The present invention provides a side-sound buzzer structure, comprising: a first housing having a first chamber and a first opening; a first partition formed around the first chamber, and Forming a second chamber and a second opening; one side sound outlet formed by the second chamber extending outwardly and forming a side opening by the first casing; and a piezoelectric sound piece covering At the second opening.

Through the implementation of this creation, the following advancements can be achieved: 1. The structure of the side-out buzzer can be made lighter and thinner. Second, it can be easily installed in thin product applications. Third, in the case of side (side) sound, up to the alarm regulations 3M/85dB standard. Fourth, the overall shape of the design required by the customer can be greatly reduced. 5. The benefits of the space available within the amplifier. Sixth, the application of the product can send the sound from the side of the product, without the need to send from the front or back of the product.

In order to enable any skilled artisan to understand the technical content of the present invention and implement it according to the contents, patent application scope and drawings disclosed in the specification, any skilled person can easily understand the purpose and advantages of the present invention. Therefore, the detailed features and advantages of the present invention will be described in detail in the embodiments.

As shown in FIG. 1A and FIG. 1B, this embodiment is a side-sound buzzer structure 100, comprising: a first housing 10; a first partition 20; a sound outlet 30 on one side; And a piezoelectric sound piece 40.

The first housing 10 is a main structural member of the side sounding buzzer structure 100. The first housing 10 has a first chamber 110 and a first opening 120.

The first partition plate 20 is formed in the first chamber 110 and forms a second chamber 210 and a second opening 220. The second opening 220 of the second chamber 210 is combined with the piezoelectric sound piece 40. And the second chamber 210 can function as a resonant chamber that interacts with the piezoelectric piece 40.

a side sound outlet 30 formed by the second chamber 210 extending outwardly and forming a side opening by the first housing 10; more specifically, the side sound outlet 30 can be formed by the first housing 10 A first plate body 130 and a second plate body 140 are formed.

In order to enable the sound to be smoothly led out, a guide portion is formed in the chamber between the second chamber 210 and the side sound outlet 30, that is, on the second plate body 140 of the first casing 10. The guiding portion may be a beveled guiding portion 150 or a guiding portion or a curved surface guiding portion 160. When the guide portion is a curved surface guide portion 160, the cross-sectional area of the side sound outlet port 30 is made small, so that the sound can be more concentrated.

In order to make the side sound buzzer structure 100 more robust, the first housing 10, the first partition 20 and the side sound outlet 30 of the side sound buzzer structure 100 may be an injection molding body. Molded structure.

a piezoelectric sound piece 40, which is an element that generates vibration by voltage driving and further emits an audio warning sound, such as a piezoelectric ceramic piece; the piezoelectric sound piece 40 is coupled to the first opening 120 such that the piezoelectric sound piece 40 and The first housing 10 forms a unitary structure. In order for the piezoelectric piece 40 to interact more effectively with the second chamber 210, the piezoelectric piece 40 is designed to cover the second opening 220.

As shown in FIG. 8, after testing the side-sound buzzer structure 100 of the present embodiment, under the test conditions of 3,200 Hz, 28 vpp square wave drive and measuring distance of 30 cm, the sound pressure can still reach 105 dB, so completely It meets the requirements of the customer's side (side) sound, and still meets the 3M/85dB standard of the alarm regulations.

However, the above embodiments are intended to illustrate the features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the contents of the present invention and to implement it, and not to limit the scope of the patent of the present invention. Equivalent modifications or modifications made by the spirit of the disclosure should still be included in the scope of the claims described below.
