我们正在寻找最好的硬件公司和工程师,以帮助揭示硬件产品开发背后的许多挑战,课程和哲学。

In this硬件聚光灯,我们有机会与Soundfocus联合创始人Alex Selig坐下。亚历克斯(Alex)和他的联合创始人Varun Srinivasan创立了该公司,其目标是建立革命性的音频处理技术,以赋予数百万人能够在日常生活中更好地听到的能力。在设计时,我们与Alex聊了聊灵感,用户​​测试和重要的课程。

告诉我您的故事以及它如何导致您创建音频

I grew up with hearing loss – I have hearing aids in both ears. I’ve struggled to hear the world my entire life so I guess I pay attention to what I hear more than most. When I was studying mechanical engineering and product design at Stanford I had the opportunity to really understand everything about my ears as well as the great audio systems and how to build them.

What problem were you aiming to solve with音频

Audio is a critical element of a great immersive experience with phone calls, music, and movies. Today, audio is a second class citizen on mobile phones today. Our product, Amp, fixes that. We give you great audio no matter where you are or what you are doing. This is done through a combination of great speakers and smart audio processing. To get the sound just right, we tune to your audio to your hearing, tastes, and the environment around you. So the obvious missing element on mobile devices today is sound. The sound is subpar and it’s always shooting out the wrong direction so you’re cupping your hand around the back of it hoping you get the sound to come towards you. With our product we offer personalized sound that analyzes your hearing needs, as in which frequencies of sound you hear well and which ones you don’t, your hearing tastes, and the effects of the environment around you.

告诉我您的原型哲学 - 您的过程是什么样的?

The prototyping process is really something they drill into you at Stanford. In the engineering building they had a sign on the first floor that read, ETC – express, test, cycle. This means that you give just enough form to an idea that allows you to gather useful feedback, then you test it out and gather that feedback and repeat the process over and over. It was the one thing they wanted all engineers to know because without continuous learning and testing, the products you design will fail to hit their mark and truly solve a customer’s problems.

在您的产品开发中,这种理念如何形成?

在我们的整个过程中,我们并不害怕忠诚原型。有时,这实际上可以帮助客户想象它可能是什么,而不是它是什么。一开始,您真的不想拥有太多的细节 - 您只想早日就核心概念获得反馈,问:“如果您的耳机电缆上有矩形盒子,您会买吗?”

因此,在我们让人们测试功能齐全的产品之前,我们采用了3D打印的原型,只有无电子设备的固体塑料,然后将它们交给附近公园中的人们,并问他们真正的基本问题,例如“这感觉很好,而且这适合您的口袋吗?”令人惊讶的是,即使几毫米对产品的物理形式的反应也可以产生多大差异。例如,.8mm是一个巨大的尺寸。我不骗你,.8mm生产或破坏产品。

What was the impact of 3D printing in your overall process?

您永远不会从渲染中了解的小事情将成为很大的事情。例如,像按钮。您会在CAD中看到它,就像:“哦,它看起来很大,但这并不大。”然后,您将其打印出来,就像“看起来像按钮怪兽,是一个专为学龄前儿童设计的按钮,因此他们永远不会错过它。”这些是您在3D物理上看到的各种东西。

不过,更具体地说,虚构的进来并确实改变了我们产品开发过程的动态。当我们开始开发第一个耳机适配器原型时,我们正在使用其他供应商,这些供应商大约是每个原型昂贵的3倍,而且我们无法依靠的供应商,因为它们的转折时间不一致。使用虚构的人,我实际上可以比以前做更严格的计划,因为交付是如此一致,我有一个原型合作伙伴,我的建议我实际上可以信任并且可以依靠。与您的原型合作伙伴建立良好关系是您生存的唯一方法,而虚构的人就像我们团队的扩大部分。

让我们深入研究您的产品开发的细节 - 您的第一个工作原型是什么样的?

我们要做的第一件事是将软件在iPhone/PC上运行,然后将其移植到Beaglebone上。因此,基本上,我们在上面有一个带有大型弹性徽标的特百惠盒,就像由USB电话充电器供电的耳机适配器的巨型版本。这根本不是关于硬件设计的,而是将件像MacGyver这样的碎片放在一起。我们正在一起将一个盒子盒子满足基本的肠检查。为了证明我们可以成功地将手机上的处理方法转移到硬件上。

“Fictiv came in and really changed the dynamics of our product development process…I have a prototyping partner whose advice I actually trust and can rely on.”

您的第一个使用工作原型的用户测试体验呢?

我们降落在正确的形式因素后product using the basic 3D prints, we decided to make 40 beta units of the headphone adaptor and actually sell them. Eric, the CEO of Pebble, gave us the advice that every customer who interacts with a beta needs to treat the product like it’s the real thing or else they will promise to use it and then it will sit on a shelf for three weeks. So we sold each unit for $100 each and put in extra effort with the packaging and presentation using soft tooling with really nice finishing and these nice little boxes with well designed instruction pamphlets to make people believe the beta units were like a finished product.

您从该测试中获得了什么样的信息?

这些反应很棒,人们确实将其视为真正的产品,从而为我们提供了广泛而高质量的反馈。我们了解到人们真的很喜欢它,但抱怨要记住要收取东西。而且,如果您最热情的客户(您的10个净促销员中的10个)抱怨您必须仔细聆听的特定问题。因此,当我们意识到我们可以朝着构建智能手机外壳而不是耳机适配器方面迈进时。借助我们的新产品称为AMP(现在可以在我们的网站上预订),您不需要任何其他设备。您会一直带有两个高质量的扬声器。您有令人难以置信的免费电话,所有应用程序的出色声音,耳机听起来好像已经重新制作了。这是您不必担心充电的额外奖励,当您为放大器充电时,您可以为手机充电。

“如果您过度管理混乱,那么您的动作就不够快。另一方面,如果您管理混乱,那么什么也不会发生。”

What is it like to develop a product dependent upon an OEM like Apple?

绝对是神经损坏。我不知道您是否曾经与那些为谋生手机箱的人进行交谈,但实际上,他们是在iPhone商店可以买到的第一台电话,他们在大约一个小时内飞往中国。因为每天不在市场上使用最新版本的产品都是您从该案例中失去潜在利润的一天。但是,另一方面,每个新设备都是我们制造更好产品的机会。

您在旅途开始时会给其他硬件初创公司有什么建议?

First I’d say that high quality prototyping like 3D printing is awesome, but even before you do that, you should go quicker and dirtier – fold up some paper like origami style and do a gut check. Because that gut check takes you 5 minutes and zero money. Some companies burn big holes in their pockets spending thousands of dollars on prototypes when they could have learned a lot in 5 minutes from a couple pieces of foam board duct taped together.

我给出的另一个建议是,作为一家创业公司,混乱很难管理。但是,如果您过度管理混乱,那么您的动作就不够快。另一方面,如果您管理混乱,那么什么也不会发生。找到余额。
