The sound performance of the smartphone with a built -in stereo speaker is improving year by year.In order to regenerate the audio of the smartphone at a loud volume, it is necessary to use an external speaker such as Bluetooth speaker, and it is necessary to use earphones when traveling, but in a quiet place such as your own room, it is built into your smartphone.You can fully enjoy videos and music with the sound of stereo speakers alone.However, it is a shadow where Bluetooth speakers and earphones spread, and the interest in the stereo speaker built into smartphones seems not very high.Therefore, we have developed a smartphone stand "Backboard" that can bring out the sound performance of a smartphone with a built -in stereo speaker."Backboard" is a new smartphone stand with unlikely features.

Improves the power and realism of the smartphone stereo playback sound

The left and right reflector leads to the sound of the smartphone forward, improving the power and presence of stereo regeneration sounds.Since the external speaker is not used, there is no delay in sound.

Product Name: Backboard Full Wooden Dimensions: Width 265mm Height 171mm Depth 110mm Material: Walnut Weight: 811g

The inventor Co., Ltd. planning and designed, and carefully manufactures one by one at a Vietnam factory under the management of Nichigan Co., Ltd., the longest wooden toy maker in Japan.

The reason for developing backboard is that the sound performance of the smartphone with a built -in stereo speaker is improving year by year. When listening to videos and music on a smartphone, I often used earphones and Bluetooth speakers, but if I listen to videos and music in quiet places such as my own room, I think that "the smartphone function is enough?" It has come to be like. Nevertheless, the speaker built into the smartphone is very small, so it can only produce sounds that are biased to high notes and low bass. Therefore, the power and realism during stereo regeneration are not sufficient. This is a structural fate of a smartphone that emphasizes portability. However, if the sound from the speaker located on the left and right when the smartphone is placed horizontally can be guided forward, the power and realism during stereo regeneration can be slightly improved. Based on this naturally, we started prototyping backboard. When I exhibited several prototypes at some exhibitions, I got a high reputation. In particular, it was highly evaluated by high school students and above, and we received many requests to sell quickly. So I decided to commercialize it. In commercialization, we aimed to achieve the following points. (1) Structure that leads the sound of the internal speaker located on the left and right when a smartphone is placed horizontally (2) The structure that leads the sound of the internal speaker located at the lower end when the smartphone is placed vertically (3). ) Structure that can attach a commercially available wireless charger (4) Structure that does not disturb the smartphone screen touch and button operation (5) Functional beauty and durability (6) Prototype in Japan that can be used for a long time with attachment, 1) ~ (5) was achieved. (6) was abandoned in terms of cost, but under the management of Nichigan Co., Ltd., a long -history wooden toy maker in Japan, it can be manufactured at a Vietnamese toy factory where woodworking products are produced. 。 Backboard was developed for this reason. Normally, the selling price was less than 10,000 yen, but as a result of using luxury wood for the ingredients, the result was greatly exceeded. In this era when there is a smartphone stand that can be purchased for 100 yen, I was worried that a smartphone stand that costs more than 10,000 yen will be accepted, but I decided to challenge it. Backboard is confident that the user will be satisfied with its function and luxury.

In the early stages of product development, a smartphone stand that combines a wooden square board and a smartphone supporting parts made by bending a metal stick.From that form, it was named Backboard because it was associated with the backboard of the basketball and the meaning of "back plate" expressing the product concept.

Q1.Can I use a smartphone without a built -in stereo speaker?A1.Yes, it can be used.However, I think the benefits of using are small.

Q2.Can I use it without a wireless charger?A2.Yes, it can be used.If the smartphone has a built -in stereo speaker, it will improve the sense of stereo sound by using it horizontally.

Q3.Why is stereo sound improving?A3.By setting the smartphone on the backboard horizontally, the fled to the stereo sound output from the left and right speakers of the smartphone is suppressed, and the volume that is led forward is increased by that much.As a result, the volume that reaches the user's ear increases, and the effect of improving the power and realism of stereo sounds is obtained.Although there are individual differences in how powerful and realism feel, it is certain that the volume reached from the smartphone to the user ears will result in an advantageous acoustic effect.

Q4.Do you amplify the sound of your smartphone?A4.No, the sound of the smartphone cannot be amplified.The size of the sound depends on the performance of your smartphone.

Q5.Is it suitable for use in places with loud noise?A5.No, it is not suitable for use in places with loud noise.

Q6.Can I use all the commercially available wireless chargers?A6.No, not all commercially available wireless chargers can be used.Use a circular wireless charger with a diameter of 105mm or less.We recommend using a wireless charger with a diameter of 96 mm or more.

Q7.Can I use a small wireless charger like an Apple Magsafe charger?A7.Yes, it can be used.However, it is necessary to fix it with double -sided tape (see the above [Magseef compatible wireless charger]).Use a heat -resistant double -sided tape to be used to fix the wireless charger (for example, 3m 9448A diameter 30mm).

Q8.What are the criteria for selecting a wireless charger (excluding shape and dimensions)?A8.Please use a wireless charger with power output that matches your smartphone.[15W output] iPhone12, Samsung Note 10+ / 10+ 5g, Sharp Aquos R3 / R5G, [10W output] Samsung Galaxy S11 / S10+ / S9 / S9+, [7.5W output] iPhone11 /XS /XS Max /XR /X /8 /8 Plus, [5W output] Sony Xperia 1 II /XZ3 /XZ2 Premium /Pixel4 /3 /3 XL, Huawei P30 Pro, etc.

Q9.What are the wireless chargers (up to 10W output) and wireless charger (up to 15W output) included in the return product?A9.The wireless charger (up to 10W output) is 10W, 7.It is a displaced Qi pad with a diameter of 100mm that supports 5W and 5W charging.A Qi pad (color is black), which is equivalent to the manufacturer reference price of 2,000 yen, will be the included return product.The wireless charger (up to 15W output) is 15W, 10W, 7.A circular wireless charger with a diameter of 105mm that supports 5W charging.It also supports the charging of Sony / pixel / Sharp / Huawei.A wireless charger (color is black), which is equivalent to a normal price of about 1,200 yen, will be the included return product.
