Description

Technical Field

[0001] This invention relates to the field of positioning devices, and in particular to a positioning finder. Background Technology

[0002] A location tracker is a device used for location positioning and tracking. During outdoor activities such as mountaineering and camping, people commonly attach a location tracker to their backpacks. Existing location trackers are mainly divided into two types: electronic location trackers equipped with GPS or other positioning modules, whose primary function is large-area positioning; and location trackers for small-area positioning, facilitating the search for items. These trackers primarily use sound to alert the user of their location. Current sound-based location trackers mainly use speakers for alerts and alarms. Speakers consume a lot of power during use, typically lasting only 3-5 days, and require battery replacement after the battery is depleted, making them extremely inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a power-saving and loud-voice-powered location finder.

[0004] The present invention is achieved through the following technical solution: a location finder, characterized in that: it includes a housing, the interior of which is provided a first resonance cavity located above, a second resonance cavity located below, and a buzzer for separating the first resonance cavity and the second resonance cavity and for emitting sound; the location finder also includes a motherboard connected to the buzzer for controlling the power supply of the buzzer and a power supply device connected to the motherboard for supplying power to the motherboard.

[0005] To better implement this solution, the following optimization schemes are also provided:

[0006] Preferably, the first resonant cavity and the second resonant cavity form two spaces of different sizes.

[0007] To facilitate light projection and positioning, a light-transmitting hole is provided in the middle of the buzzer plate, a light source controlled by the main board is provided above the light-transmitting hole, and a light-transmitting channel connecting to the outside is provided at the bottom of the second resonance cavity. The light emitted by the light source is projected outward through the light-transmitting hole, the second resonance cavity and the light-transmitting channel in sequence.

[0008] Preferably, a light-transmitting projection component is installed in the light-transmitting channel. The projection component has a predetermined projection pattern, and the light source projects onto the projection component to project and display the projection pattern outward.

[0009] To further amplify the sound, the housing or projection component is also provided with a sound-emitting through hole for convenient sound generation.

[0010] Preferably, the outer diameter of the buzzer is 6.5mm-50mm, and the thickness of the buzzer is 0.15mm-0.85mm.

[0011] Preferably, the buzzer chip includes a substrate and a conductive ceramic dielectric disposed on the substrate, wherein the substrate is made of one or any combination of copper sheet, stainless steel sheet, nickel alloy sheet and iron sheet.

[0012] To prevent light from scattering, the projection component is provided with a light-transmitting column extending into or below the light-transmitting hole.

[0013] Preferably, the motherboard is installed in the housing and located above the buzzer, and the motherboard and the buzzer are connected by a pin or a flexible hinge.

[0014] For ease of installation, the housing includes a lower housing and an upper housing.

[0015] Preferably, the upper surface of the upper housing is provided with a recessed battery compartment, the power supply device is a button battery and is installed in the battery compartment, and a cover is also provided on the top of the battery compartment.

[0016] Preferably, the motherboard is further provided with a communication module that can connect to external devices.

[0017] To ensure that the sound is more focused and does not diffuse, the diameter of a single hole for facilitating sound generation shall not exceed 10mm.

[0018] To help amplify the sound by rotating it in the air, the second resonating cavity is funnel-shaped, wider at the top and narrower at the bottom.

[0019] Furthermore, to help amplify the sound by rotating it in the air, the second resonating cavity and the first resonating cavity form a funnel-shaped air circulation system.

[0020] Preferably, the diameter of the light-transmitting hole does not exceed 6 mm.

[0021] Compared with previous technologies, the beneficial effects of the present invention are as follows:

[0022] 1. The location finder described in this invention uses a buzzer to generate sound, which consumes less power than other sound-generating components such as buzzers or speakers. When using a button battery, its service life can be extended by more than double. Furthermore, the housing is provided with two resonance cavities, which work together to amplify the sound emitted by the buzzer.

[0023] 2. The positioning finder of the present invention also has a light-transmitting hole in the buzzer plate, so that the light emitted by the light source can be projected onto the projection component through the light-transmitting hole, thereby projecting a predetermined mark pattern outward, which makes it convenient for users to find in dark environments.

[0024] 3. The location finder described in this invention has a lightweight and thin overall structure, is easy to install, and has a reasonable design that facilitates its widespread use. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in detail with reference to the accompanying drawings:

[0036] Example 1:

[0037] like Figure 1-8As shown, a location finder is characterized by comprising a housing 1, wherein the housing 1 has a first resonant cavity a located above, a second resonant cavity b located below, and a buzzer 2 for separating the first resonant cavity a and the second resonant cavity b and for emitting sound. The location finder also includes a main board 3 connected to the buzzer 2 for controlling the power supply of the buzzer 2, and a power supply device connected to the main board 3 for supplying power to the main board 3.

[0038] The location finder uses a buzzer 2 to generate sound. Compared to buzzers or loudspeakers, the buzzer 2 consumes less power and has a longer operating time, requiring only a button battery. The buzzer 2 mainly consists of a piezoelectric ceramic plate with electrodes printed on both sides and a metal plate (brass or stainless steel). An adhesive is used to bond the piezoelectric vibrating plate and the metal plate together. When a DC voltage is applied between the two electrodes of the piezoelectric vibrating plate, mechanical deformation occurs due to the piezoelectric effect, producing sound. Because the sound emitted by the buzzer 2 is relatively quiet, the location finder has resonance cavities below and above the buzzer 2. The sound emitted by the buzzer 2 resonates with the first resonance cavity a and the second resonance cavity b, achieving a double-ended sound amplification effect.

[0039] Preferably, the first resonant cavity a and the second resonant cavity b form two spaces of different sizes.

[0040] To facilitate light projection positioning, a light-transmitting hole 21 is provided in the middle of the buzzer 2. A light source 31 controlled by the main board 3 is provided above the light-transmitting hole 21, and a light-transmitting channel b1 connecting to the outside is provided at the bottom of the second resonance cavity b. The light emitted by the light source 31 is projected outward through the light-transmitting hole 21, the second resonance cavity b and the light-transmitting channel b1 in sequence.

[0041] Preferably, a light-transmitting projection component 5 is installed in the light-transmitting channel b1. The projection component 5 has a projection pattern, which can be designed as a predetermined mark. The light source 31 projects onto the projection component 5 to project and display the mark outward.

[0042] The symbol is not restricted and can be of any shape; in this embodiment, a cross shape is preferred.

[0043] To further amplify the sound, the housing 1 or projection component 5 is also provided with a sound-emitting through hole 51 for facilitating sound generation.

[0044] The projection component 5 is provided with a light-transmitting column 52 extending into or below the light-transmitting hole 21. The light projected by the light source 31 can be extended to the projection component 5 through the light-transmitting column 52, which can prevent the light from spreading. In addition, the light-transmitting column 52 can partially block the light-transmitting hole 21, thereby increasing the volume of the sound amplification.

[0045] Because the buzzer 2 is a thin sheet structure, it is prone to cracking when a hole is drilled in the center of the buzzer 2 to allow light to pass through and when it vibrates to produce sound. After long-term experiments, it was found that this problem can be solved by using a specially designed thickness and diameter of the buzzer 2. Therefore, this embodiment provides the following preferred data for the buzzer 2: the outer diameter of the buzzer 2 is 6.5mm-50mm, and the thickness of the buzzer 2 is 0.15mm-0.85mm.

[0046] Preferably, the buzzer chip 2 includes a substrate and a conductive ceramic dielectric disposed on the substrate, wherein the substrate is one of copper sheet, stainless steel sheet, nickel alloy sheet and iron sheet or any combination thereof.

[0047] Preferably, the motherboard 3 is installed in the housing 1 and located above the buzzer 2, and the motherboard 3 and the buzzer 2 are connected by a pin 6.

[0048] For ease of installation, the housing 1 includes a lower housing 11 and an upper housing 12.

[0049] Preferably, the upper surface of the upper housing 12 has a recessed battery compartment 121, and the power supply device is a button battery installed in the battery compartment 121. A cover 8 is also provided on the top of the battery compartment 121. The connection method between the button battery and the motherboard is as follows: Figure 4 Connect to the contact point 4 shown.

[0050] Preferably, the motherboard 3 is further provided with a communication module that can be connected to external devices.

[0051] To ensure that the sound is more focused and does not diffuse, the diameter of a single hole for facilitating sound generation shall not exceed 10mm.

[0052] To help amplify the sound by rotating it in the air, the second resonating cavity b is funnel-shaped, wider at the top and narrower at the bottom.

[0053] Furthermore, in order to help amplify the sound by rotating it in the air, the second resonant cavity b and the first resonant cavity a form a funnel-shaped air circulation system.

[0054] Preferably, the diameter of the light-transmitting hole 21 does not exceed 6 mm.

[0055] Example 2:

[0056] like Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the motherboard 3 and the buzzer 2 are connected by a flexible hinge 7. Using the flexible hinge 7 to connect the motherboard 3 and the buzzer 2 allows for a thinner overall structure of the positioning finder compared to the connection method using the pin 6.

[0057] Although the present invention has been illustrated and described through specific embodiments and alternative methods, it should be understood that various changes and modifications may be made without departing from the spirit and scope of the invention. Therefore, it should be understood that the present invention is not limited in any sense except by the appended claims and their equivalents.
